No full text5. Tetramorium exile Csösz & Radchenko New species (figs 39-42) Description of Worker (figs 39-42). Morphometric data of the holotype worker: CL: 725; CW: 675; FR: 240; FL: 240; SL: 585; ML: 790; MW: 440; PEW: 215; PEH: 240; NOH: 130; NOL: 130; PEL: 155; PPW: 240; PPL: 160; PPH: 210; SPL: 90; SPSP: 130; EL: 135; EH: 100; ED: 170; Small size, CS 695 [620, 743]. Whole body and appendages brown to dark brown. Head elongated, CL/CW 1.06 [1.04, 1.08], with very feebly convex sides, straight occipital margin and narrowly rounded occipital corners. Eyes small, EYE 0.167 [0.158, 0.175]. Frons very narrow, FR/CS 0.34 [0.33, 0.35], frontal lobes as wide as frons, FL/FR 1.0 [1.0, 1.02]. Scape very long, SL/CS 0.84 [0.82, 0.85], without longitudinal dorsal carina basally, smooth and shiny. Promesonotal dorsum slightly convex, metanotal groove very shallow or completely absent. Propodeal teeth moderately long and acute, directed mainly upwards. Petiolar node trapezoidal in profile, NOH/NOL 1.04 [0.90, 1.16], petiole relatively high, PEH/NOL 1.83 [1.70, 1.96]. General appearance moderately rugose, ground surface microreticulate, dull. Head dorsum longitudinally rugose, ground surface microreticulate, occiput rugoso-reticulate. Alitrunk dorsum and petiolar node rugoso-reticulate ground surface microreticulate, mesopleuron usually rugulose and microreticulate, dorsum of postpetiole longitudinally rugulose and microreticulate. Polygonal striation continuous on 1st gastral tergite (see fig. 8.). Ventral surface of head with several short and few moderately long, straight setae arising posterior to buccal cavity (see fig. 5.). Gynes and Males are unknown. Material examined: HOLOTYPE [[worker]]: AFGHANISTAN - O-Afghanistan, Walang, 2520m, Salangtal, Hindukusch, 29.09.1952. leg. J. Klapperich (HNHM); PARATYPES: 35 [[workers]] from the same nest (3[[workers]] / HNHM, 4[[workers]] / MIZ, 25[[workers]] / NHMW 1[[worker]] / PCAS). Morphometrics: (33 workers were measured). Diagnosis. According to the literature (Collingwood 1961a, 1961b, Pisarski 1967a, 1967b, 1969) and collection materials there are no similar Tetramorium species, described from Afghanistan. Workers of T. exile n. sp. differ from related species by absence of psammophore, relatively small eyes, (EYE, Table 1.), extremely narrow firons, the very long and smooth scape (FR/CS and SL/CS, Table 1.), and by the trapezoidal petiolar node (NOH/NOL and PEH/NOL, Table 1.). Tetramorium exile n. sp. is mostly similar to T. anatolicum sp.n. and T. chefketi, but differs from the latter by the shape of petiolar node: in T. exile n. sp. it is relatively high and short, trapezoidal in profile, while in T. chefketi it is relatively low and longer, cubic in profile, (PEH/NOL and NOH/NOL, Table 1.). The following Discriminant D(3a) function proves the separation between T. exile n. sp. and T. chefketi: D(3a) = 0.052 PPW -0.057 FL -0.081 NOL +14.667, T. exile n. sp. D(3a) = +3.418 ±0.901 [+2.169, +4.756] (n=33), T. exile n. sp., holotype D(3a) = +3.023, p<0.001, T. anatolicum n. sp. D(3a) = +3.164 ±0.796 [+1.746, +4.606] (n=38), T. anatolicum n. sp., holotype D(3a) = +3.246, p<0.001, T. chefketi D(3a) = -3.417 ±1.004 [-5.680, -0.524] (n=107), T. chefketi lectotype D(3a) = -4.179, p<0.001; T. sarkissiani lectotype D(3a) = -2.809, p<0.001; T. turcomanicum syntype worker D(3a) = -4.169, p<0.001. T. exile n. sp. differs from T. anatolicum n. sp. by its longer scape and narrower firons (SL/CS and FR/CS, Table 1.). The following Discriminant D(2a) function provides the separation between T. exile n. sp. and T. anatolicum n. sp.: D(2a) = 0.081 SL - 0.151 FL - 7.652 T. exile n. sp. D(2a) = +2.683 ±0.762 [+1.193, +3.493] (n=33), T. exile n. sp., holotype D(2a) = +3.493, p<0.001, T. anatolicum n. sp. D(2a) = -2.683 ±1.064 [-4.682, -0.042] (n=38), T. anatolicum n. sp., holotype D(2a) = -3.117, p<0.001. For further combination of morphometric characters see Table 1-2. Distribution. Known from the type locality only. Etymology. This adjective [exilis / -e; exile (neutrum) = slender] refers to the elongate body of this species.Published as part of Csösz S., Radchenko, A. & Schulz, A., 2007, Taxonomic revision of the Palaearctic Tetramorium chefketi species complex (Hymenoptera: Formicidae)., pp. 1-38 in Zootaxa 1405 on pages 22-2

His collection contains several specimens of the new species. Diagnosis. The species is very similar to D. hirtipes, hardly distinguishable from it in general appearance. Specimens of D. morawitzi are slightly smaller (body length: female 9–14 mm [N = 50], fig. 1–4; male 9.5–13.5 mm [N = 50], fig. 9, 10, 13, 14, 17) than D. hirtipes (female 11.5–15.5 mm; male 10–15 mm), but still broadly overlap in size. The main character, which sharply distinguishes these species is the structure of galeal surface in both males and females, rippled by wavelike lines in D. morawitzi (fig. 20, 21) and completely covered with small tubercles in D. hirtipes (fig. 22, 23) as well as in D. oraniensis (fig. 26, 27) and D. albipila (fig. 28). The galeal surface is intermediate in D. sinuata (fig. 24, 25) and partly D. tubera Warncke, 1973 (fig. 29). However, the latter species differs sharply by the structure of the gonostylus, which has three well-developed processes. In comparison with D. hirtipes, the central apical part of male S 6 in D. morawitzi is more produced anteriorly (fig. 35, 38), the apical projections on S7 are more broadly rounded (fig. 36, 39), S8 is wider, with more projected outgrowths at each side (fig. 37, 40–42), the apical part of S8 is wider and rounded, with two separated teeth on its the ventral side (fig. 43), which are shorter and closer than those of D. hirtipes (fig. 44) and D. sinuata (teeth connected in D. albipila). The inner process of the gonostylus has a shorter fringe of hairs on the margin (fig. 45, 47, 49, 50, 61 – 66), similar to that of D. albipila (fig. 49, 50) and D. sinuata, but distinct from the very long branched hairs in D. hirtipes (fig. 46, 48, 55, 56). The base of the gonostylus in D. morawitzi is untoothed, only with an elongated area that is rounded, crest-shaped, and protruded apically (fig. 51, 61); in D. albipila the base of the gonostylus has protrusion in the form of a small flat visor, which is widely rounded (fig. 54), whereas in D. hirtipes is a triangular tooth forming a curved inward axil, fig. 57, 58). In D. oraniensis this tooth is more rounded apically (fig. 59, 60). Description. Male: holotype—one of the most recently collected specimens which by the size of the body and the color of hairs (fig. 17–19) occupies an intermediate position between the forms that were at the extremes by these parameters (fig. 9–16). Body length ( vertex–T7): 11 mm (paratypes: 9.5–13.5 mm), Mesosoma: W (between tegulae) = 2.5 mm (paratypes: 2.3–2.8 mm). Head: L = 2.5 (paratypes: 2.4–2.6 mm), W = 2.8 mm (paratypes: 2.7– 3.1 mm). Face mainly covered with long white, grayish-white and small admixture (in some paratypes with large admixture or without it) of dirty yellow hairs adjacent to clypeus obscuring integument (fig. 12, 16, 18). Pubescence sparse on vertex near ocelli, with admixture of dark brown and black hairs (fig. 19). Malar distance very short, as in female (see below). Thorax dorsally mostly with dirty yellowish hairs, ventrally and laterally with light white ones (scutum in some paratypes covered with grayish-white hairs), center of scutum with little admixture of dark hairs. Hind tibia (fig. 32–34) intermediate structure between D. hirtipes and D. sinuata. Apical bands on terga consisting of different hairs, from white to dirty yellow (or almost reddish): on T1 widely interrupted, T2 whole (or interrupted narrowly), T3–T6 with continuous apical bands. T1–T3 at base with long erect white and dirty yellow (or grayish-white) hairs, on T4–T6 with such erecte light hairs located at sides of metasoma, otherwise covered with short dark brown or black hairs (on T4–T5 often with admixture of erect light hairs anterior to apical band), T7 covered with black and dark brown, relatively long, appressed hairs with great admixture of light hairs on the sides of terga. All sterna apically lightened, translucent, with narrow band of short, light white (or gray) hairs, on S5 with admixture of reddish-yellow hairs on sides (fig. 11, 15) (certain paratypes, particularly small-sized, with long and densely pubescent sterna). Inner process of gonostylus with short, thick, almost unbranched hairs (fig. 63), except some hairs with small number of short side branches (Fig. 66). All different color variants of body pubescence (same as at females) are observed throughout the range of the species. Lighter forms usually characteristic for smaller specimens. Female (fig. 1 – 8). Body length: 10.5–14 mm. Mesosoma: W (between tegula) = 2.6–3.3 mm. Head: L = 2.8– 3.2; W = 3.3–3.7 (in SIZK was found 2 very small specimens of females, with body length only 8.5 and 9 mm; mesosoma W = 2.0– 2.1 mm; head: L = 2.3–2.4; W = 2.8–3.0 mm; one collected in environs of Kiev, and second in village Zinkiv, Poltava Region of Ukraine). Face mainly with light-colored (white or gray) hairs, with little (fig. 8) or significant (fig. 7) admixture of dark hairs on frons and vertex. Malar distance very short (0.87× shorter than mandible width at the base; fig. 30), as in other representatives of this group. Mesonotum with light gray, yellowish-gray or yellowish-brown (almost reddish) hairs, at middle with little (fig. 2, 4) or greater admixture of dark brown or black hairs (fig. 1, 3). Metasoma with broad, white, apical hair bands on T2–T4 (on T2 often narrowly interrupted), on basal part covered by erecte and decumbent black hairs, T5 with very dense, appressed, dark gray (or grayish-brown) hairs apically, remaining surface covered with long, dark hairs; prepygidial and pygidial fimbria dark gray or grayish-brown. Pygidial plate narrowly elongated at apex, relatively deeply excised apically (fig. 31). Apical parts of sterna slightly enlightened, S3–S5 with continuous and wide apical bands of dark gray-brown (fig. 5) or lighter yellowbrown (fig. 6) plumose erect hairs. Scopa on hind legs golden-yellow, sometimes lighter: grayish-yellow to grayish-white (fig. 1–4). Distribution. The new species occurs from Vinnitsa Region of Ukraine to western Kazakhstan, and from St. Petersburg to the south of the Crimean Peninsula, the Caucasus and Turkey (fig. 67). Most likely, D. morawitzi is rather widespread, but study of European collections is needed to clarify occurrence across the Palaearctic realm. In some regions, for example in western Kazakhstan and in the Crimea, specimens of D. morawitzi are more common than those of D. hirtipes. Floral visitation. Based on the label data, females prefer to collect pollen from plants of the families Asteraceae (mostly Inula britannica, Cichorium intybus and Picris hieracioides) and Plumbaginaceae (Limonium gmelini), although some females were recorded on Apiaceae (Eryngium planum), Boraginaceae (Echium sp.), Caprifoliaceae (Scabiosa isetensis, S. ochroleuca) and Lamiaceae (Lycopus europaeus, Origanum vulgare, Stachys sp.). In addition, single males were collected on plants of Campanulaceae (Campanula sp.) and Convolvulaceae (Convolvulus arvensis). Dasyposa morawitzi has supposedly a wider range of trophic links than D. hirtipes, but these data also need to be clarified because these two species have long been confused. Flight period. End of May (in the Crimea from mid-May) — mid- September. There is one unusually smallsized female specimen (9 mm long) in the collection of SIZK that was collected in Kiev (Ukraine) on 18.04.1954. Such early flight of this species is probably an artifact. Comments. The discovery of this new species r

Paratype: 1 ♂ with the handwritten label: “ Dasypoda ♂, Vila Nova de Milfontes (P[ortugal]) [37.723, -8.788], 20-V-2012, A.Livory u R.Coulomb leg.”. Both specimens are stored in the collection of Naturalis Biodiversity Center, Leiden, the Netherlands (RMNH). Etymology. Named after Denis Michez, an authority on Dasypoda and other bees. Diagnosis. Dasypoda michezi sp. nov. may be regarded a representative of the subgenus Heterodasypoda due to the possession of all its diagnostic features, namely the shape and structure of maxillary palpi, galea (Fig. 7), malar space, nervulus (Fig. 1), S6–8 (Figs 23, 27, 31, 35, 39), genitalia (Figs 43, 47, 51, 55), and gonostylus (Figs 59, 63, 67, 68). The new species differs from other species of this subgenus by having: apical projection of S6 apically deeply emarginated in the form of wide triangle (Fig. 23), apicolateral processes of S7 with triangle shaped distal expansion (Fig. 28), inner ventral lobe of gonostylus with only few setae (Figs 63, 71), distal half of external lobe of gonostylus significantly widened and convex in middle of outer surface, diamond-shaped (Figs 43, 47, 51, 55) and its inner surface with several hairs, each of which inserted into crater-like raised alveoli (Figs 67–69, 72). Description. Male: Holotype. Body length ( vertex to T7): 11.8 mm (paratype: 12.0 mm). Mesosoma: W (between tegulae) = 3.0 mm (same in paratype). Head: L = 2.9 mm (paratype: 3.1 mm), W = 3.3 mm (paratype: 3.5 mm); Body black, head slightly wider than long (Figs 3, 4), clypeus, densely punctured by oblique, downward punctures. Lateral edges of clypeus with impunctate bands on sides and apex of clypeus with narrow depressed band (Fig. 4). Face below antennal toruli with relatively wide (equal to the width of scapus), smooth, almost impunctate band reaching base of clypeus. Malar space narrow, 0.15× as long as broad, in 2× shorter than pedicel. Body mostly covered with light yellow-grey hairs (Figs 1–6); head also with such hairs except upper part of face between compound eyes and vertex covered with sparse brown hairs (Figs 3, 4). Back of head and thorax with long, semi-erect hairs. Wings slightly infuscate, notably in distal half. Legs with long greyish-yellow pubescence, apart from dense short dark-yellow pubescence of inner side of metabasitarsus, and very short grey hairs of 2–5th tarsomeres with a sparse sheaf of long hairs on apices of 2–4th tarsi. T1–2 covered by light, long erect hairs, T3–5 with semi-erect hairs and T6–7 with appressed hairs (T5–6 with pale pubescence only on the margin and sides), each hair rising from an oblique backward-directed puncture. Distances between puncture about 2–4× as long as diameter of puncture. Pubescence sparse and revealing surface of tergum. T2–6 with very short, thin branched dark-brown hairs situated in areas between long hairs (length of lateral branches equal to 1/2–2/3 of total hair length). T5–6 with basal parts bearing only dark-brown hairs with small admixture of light hairs on sides. Basal parts of sterna densely punctate, mainly bearing dark brown hairs. Central part of S5–6 with larger sparse punctures. S3–5 with apical bands of appressed dark-brown hair, with longer light yellow-grey hairs on sides of sterna (Fig. 6). Apical part of S6 with wide and deeply emarginated outgrowth (Fig. 23); distal part of latero-apical processes of S7 triangularly expanded (Fig. 28); apex of S8 posterodorsal part with transverse carina slightly notched in center (Fig. 35; carina shown by white arrow). Inner ventral lobe of gonostylus almost bare on apex (Figs 63, 71); distal half of external lobe of gonostylus significantly widened and convex on its outer surface, diamond-shaped (Figs 43, 47, 51, 55), its inner surface with several hairs, each inserted into crater-like raised alveoli (Figs 67–69, 72). Female: unknown. Distribution. South-western Portugal (Fig. 73). Floral visitation. Pollen grains of a Cistus plant (Cistaceae) were found on the body of the paratype (Fig. 70). Other representatives of this subgenus, in particular D. morotei and D. pyrotrichia, are also associated with Cistaceae (Michez et al. 2004b, 2008; Ruiz 2013; Özbek 2014), whereas D. albimana is mostly found on Asteraceae, but also recorded on Cistaceae, Lamiaceae and Rosaceae (Michez et al. 2003, 2004b; Ruiz 2013). Flight period. May. All other Heterodasypoda species also fly in late spring to summer: D. albimana —from May to July (Michez et al. 2003); D. morotei —from May to August, with some sporadic records in April and September and one—later in November (Ornosa & Ortiz-Sánchez 1998, 2004); D. pyrotrichia —from mid May to late August (Grace 2010). Comparative remarks. Dasypoda michezi sp. nov. is most likely to be confused with D. albimana. Both species have similar body length and size of head, approximately same surface punctation of different body parts and colour of pubescence. However, D. michezi sp. nov. is characterized by the shorter first flagellar segment (Figs 15, 19) and differs from all other species of the subgenus in the ratio of different flagellar segments (Figs 17–18, 21–22; Tabl. 1). Flagellomeres 3–8 of D. michezi sp. nov. are cylindrical (Fig. 15), the same as in D. albimana (Fig. 16) and D. pyrotrichia (Fig. 18), in contrast to D. morotei, in which they are slightly curved (Fig. 17). The clypeus of D. michezi sp. nov. (Figs 3, 4) lacks an impunctate median band (this feature is almost invisible when pubescence is undamaged), likewise in D. albimana. Also, the apex of the clypeus is straight in D. michezi sp. nov. (the clypeus of D. morotei and D. pyrotrichia has a more or less distinct, impunctate median band; also it the apex is emarginated in D. morotei). The glossa of D. michezi sp. nov. (Fig. 11) is very narrow and long: 1.5× longer than in D. albimana (Fig. 12) and D. morotei (Fig. 13), but has same length as in D. pyrotrichia (Fig. 14). The most noticeable differences concerns the ratio of the glossa width at base to its length: this proportion is about 1: 6.7 in D. michezi sp. nov., 1: 4.6 in D. pyrotrichia, 1: 3 in D. albimana and 1: 2.3 in D. morotei (Figs 11–14). The surface of the galea of D. michezi sp. nov. (Fig. 7) is clearly structured with many small tubercles merged into sinuous lines in many places, and is less shiny than in D. albimana and D. pyrotrichia (Figs 8, 10). This surface is completely covered with separate small tubercles in D. morotei (Fig. 9).

The main significant differences between D. michezi sp. nov. and the other three species of Heterodasypoda concern the structure of S6–8 of males. The outgrowth on apical part of S6 is significantly expanded at apex (ratio between width of outgrowth at base to its width at apex is 1: 1.25), apically deeply emarginated in the form of wide triangle (Fig. 23) in D. michezi sp. nov., unlike other species in which such outgrowth on apex is not expanded (in D. albimana and D. morotei; Figs 24, 25) or almost undeveloped (in D. pyrotrichia; Fig. 26). The new species also differs in the structure of latero-apical process at S7 (Figs 27–30). S8 of D. michezi sp. nov. is chunkier (Figs 31, 39), and superficially appears similar to D. albimana (Figs 32, 40), but significantly differs from that of D. morotei, which has undulating depressions on the sides of basal part of this segment (Figs 33, 41; shown by black arrows), and D. pyrotrichia is possessing more extended sides on the basal part of this segment (Figs 34, 42). The transverse carina situated anteriorly to the apex of the inner part of S8 has a small notch in the center in D. michezi sp. nov. (Fig. 35), (cf. D. albimana and D. morotei (Figs 36, 37) in which it is more deeply cut in or even completely bilobed in D. pyrotrichia (Fig. 38)). The inner ventral lobe of the gonostylus is almost bare in D. michezi sp. nov., with a few thin and short setae (Figs 63, 71), unlike other species, in which this lobe is covered with numerous, more or less long and pointed setae (Figs 64–66). The distal half of external lobes of the gonostylus of D. michezi sp. nov. is considerably widened and convex in the middle of the outer surface, diamond-shaped (Figs 43, 47, 51, 55). Unlike the new species, these lobes are narrow or more strongly elongated toward apex and widely concave in the middle of outer surface in other discussed species (Figs 44–46, 48–50, 52–54, 56–58). The inner medial surface of the outer lateral lobe of gonostylus is bearing several hairs, each of which is inserted into the crater-like raised alveoli (Figs 67–69, 72) in D. michezi sp. nov.; no such hairs are found in other species of Heterodasypoda.Published as part of Radchenko, Vladimir G., 2017, A new bee species of the genus Dasypoda Latreille (Hymenoptera, Apoidea) from Portugal with comparative remarks on the subgenus Heterodasypoda Michez, pp. 164-176 in Zootaxa 4350 (1) on pages 167-174, DOI: 10.11646/zootaxa.4350.1.10, http://zenodo.org/record/105202

Basal and apical margins of S 1–4 yellowish with apical bands of white erect hairs. Pp as in Fig. 2 h. Floral visitation. Most specimens were collected on Limonium meyeri (Boiss.) Kuntze (Plumbaginaceae) but six females were found on Galatella villosa (L.) Rchb.f. (= Linosyris villosa (L.) DC.) (Asteraceae). The species might be eclectic oligolege (sensu Müller & Kuhlmann 2008) but palynological analysis is required for confirmation. Biotope. Only found in xerophytic steppe. Distribution. Crimea. Only known from the type locality. Comment. M. budashkini seems to be closely related to M. ezoana and M. sibirica. The latter two species show wider East-Palaearctic distribution (Michez & Eardley 2007). Crimea could have been an isolated glacial refugia where M. budashkini shifted on alternative host-plants. All females of M. budashkini have been collected foraging on Plumbaginaceae or Asteraceae while M. ezoana and M. sibirica are Fabaceae specialist and generalist respectively (Michez et al. 2008).Published as part of Michez, Denis, Kuhlmann, Michael, Ivanov, Sergey P. & Radchenko, Vladimir G., 2012, Description of four new species in the bee genus Melitta Kirby, 1802 (Hymenoptera: Melittidae), pp. 57-67 in Zootaxa 3337 on pages 58-61, DOI: 10.5281/zenodo.28134

Queens, males and ecology unknown. T a x o n o m i c n o t e s. T. pisarskii the most resembles T. kabulistanicum, sharing with the latter the character of sculpture on the first gastral tergite. Moreover, holotype and paratype specimens of T. pisarskii were originally included by Pisarski (1967) to the paratype series of T. kabulistanicum. Nevertheless, Pisarski (loc. cit., p. 405) noted that “Workers from Hassan Guilan have somewhat coarser, but more regular sculpture than those from Cheikhabad” (out translation from French). T. pisarskii distinctly differs from T. kabulistanicum by the sculpture of mesosoma and waist: the mesosomal dorsum is with more regular, almost straight longitudinal rugae, the waist dorsum is with regular longitudinally-concentric rugae vs. the mesosomal and waist dorsum are with sinuous longitudinal rugae in the latter species. Additionally, longitudinal rugosity on the head dorsum in T. pisarskii is less coarse, number of rugae between frontal carinae level with the eyes ≥ 20 (≤ 15 in T. kabulistanicum).Published as part of Radchenko, A.

Diagnosis. Workers of T. sanetrai n. sp. can be separated from related species by the absence of psammophore, relatively coarse body sculpture, cubic petiolar node (NOH/NOL and PEH/NOL, Table 1.) and very short scape (SL/CS, Table 1.). Workers of T. sanetrai n. sp. mostly resemble those of T. rhodium and T. alternans. Tetramorium alternans has microreticulate sculpture on dorsum of petiole and postpetiole with very feeble rugulae, and microreticulate, in contrast with T. sanetrai n. sp. dorsum of petiolar node and postpetiole rugoso-reticulate and microreticulate. Differentiation between T. sanetrai n. sp. and T. rhodium is based on microreticulation of the body including gaster and scape sculpture. Tetramorium rhodium has stronger microreticulation between the primary ornamentation, best visible on head, petiole and postpetiole dorsum, which is strongly and irregularly rugose with densely microreticulate ground surface. In T. sanetrai n. sp. especially the dorsal surface of petiole is partially unsculptured and shining between the rugulae. The scape of T. rhodium is strongly sculptured, parallel costulae cover the whole surface of scape, in contrast to T. sanetrai n. sp. the scape is smooth and shinning at least proximally, distal end sometimes very feebly costulate. First gastral tergite of T. rhodium is basally microreticulate, that of T. sanetrai n. sp. is never microreticulate, but polygonally striate. Moreover, CS/PEW and CS/PPW give appropriate discrimination between T. sanetrai n. sp. and T. rhodium (Table 1.). For separation between T. sanetrai n. sp. and T. rhodium the following Discriminant D(5) function is provided: 0.114 FR - 0.016 CS + 0.043 SL - 0.026 PEW - 0.086 PPW - 13.907 results of D(5) analysis: T. sanetrai n. sp. D(5) = -2.448 ±0.833 [-3.977, -1.137] (n= 15), T. sanetrai n. sp. holotype D(5) = -1.257, p<0.001. T. rhodium D(5) +2.425 ±1.155 [+4.643, +1.155] (n= 22), T. rhodium syntype series D(5) mean = +2.652 (n= 4). The less complicate Discriminant D(3b) function gives separation: D(3b) = 0.118 MW - 0.121 PEH - 0.084 PPH - 4.585. T. sanetrai n. sp. D(3b) = -2.643 ±0.901 [-4.022, -0.882] (n= 15), T. sanetrai n. sp. holotype D(3b) = -1.302, p<0.001. T. rhodium D(3b) = +2.643 ±1.449 [-0.619, +4.595] (n= 22), T. rhodium syntype series D(3b) mean +3.665 (n= 4). Petiole and frons characters (NOH/NOL, PEH/NOL, FR/CS, Table 1.) give appropriate separation between T. sanetrai n. sp. and T. alternans. For separation between T. sanetrai n. sp. and T. alternans the following Discriminant D(2b) function is provided below: T. sanetrai n. sp. vs. T. alternans D(2b)= 0.093 FR - 0.148 NOL - 2.941 results of D(2b) analysis. T. sanetrai n. sp. D(2b) = -2.647 ±0.866 [-4.206, -0.982] (n= 15), T. sanetrai n. sp. holotype D(2b) = - 1.528, p<0.001; T. alternans D(2b) +2.647 ±0.878 [+1.069, +4.647] (n= 34), T. alternans lectotype D(2b) = +1.969, p<0.001, T. kahenae lectotype D(2b) = +1.070, p =0.01. Gynes of T. sanetrai n. sp. can be distinguished by lacking of psammophores, smooth scape, wide scutum, (MW/CS Table 2.) relatively narrow petiole and postpetiole, (WAIST Table 2.) and rugo-reticulate katepisternum. Gynes of T. sanetrai n. sp. mostly resemble those of T. chefketi, but scape length (SL/CS, Table 2.) gives discrimination between them. For further combination of morphometric characters see Table 1-2. Distribution. Based on the studied material this species seems to be endemic to the South Italian mountains. Etymology. This species [sanetrai] is dedicated to Matthias Sanetra for his fundamental work with the genus Tetramorium.Published as part of Csösz S., Radchenko, A. & Schulz, A., 2007, Taxonomic revision of the Palaearctic Tetramorium chefketi species complex (Hymenoptera: Formicidae)., pp. 1-38 in Zootaxa 1405 on pages 28-3

Innovative Turbine Intake Air Cooling Systems and Their Rational Designing
No full textInnovative Turbine Intake Air Cooling Systems and Their Rational Designing / A. Radchenko, E. Trushliakov, K. Kosowski, D. Mikielewicz, M. Radchenko // Energies. – 2020. – № 13 (23). – P. 6201.Abstract: The efficiency of cooling ambient air at the inlet of gas turbines in temperate climatic conditions
was analyzed and reserves for its enhancing through deep cooling were revealed. Amethod of logical analysis of the actual operation efficiency of turbine intake air cooling systems in real varying environment, supplemented by the simplest numerical simulation was used to synthesize new solutions. As a result, a novel trend in engine intake air cooling to 7 or 10 ◦C in temperate climatic conditions by two-stage cooling in chillers of combined type, providing an annual fuel saving of practically 50%, surpasses its value gained due to traditional air cooling to about 15 ◦C in absorption lithium-bromide chiller of a simple cycle, and is proposed. On analyzing the actual efficiency of turbine intake air cooling system, the current changes in thermal loads on the system in response to varying ambient air parameters were taken into account and annual fuel reduction was considered to be a primary criterion, as an example. The improved methodology of the engine intake air cooling system designing based on the annual effect due to cooling was developed. It involves determiningtheoptimalvalueofcoolingcapacity,providingtheminimumsystemsizesatmaximum rate of annual effect increment, and its rational value, providing a close to maximum annual effect without system oversizing at the second maximum rate of annual effect increment within the range beyondthefirstmaximumrate. Therationalvalueofdesigncoolingcapacityprovidespracticallythe maximum annual fuel saving but with the sizes of cooling systems reduced by 15 to 20% due to the correspondinglyreduceddesigncoolingcapacityofthesystemsascomparedwiththeirvaluesdefined by traditional designing focused to cover current peaked short-term thermal loads. The optimal value of cooling capacity providing the minimum sizes of cooling system is very reasonable for applyingtheenergysavingtechnologies,forinstance,basedon the thermalstoragewithaccumulating excessive (not consumed) cooling capacities at lowered current thermal loads to cover the peak loads. The application of developed methodology enables revealing the thermal potential for enhancing the efficiency of any combustion engine (gas turbines and engines, internal combustion engines, etc.)
