The holotype is stored in the NMW. The habitus of this species is given in Fig. 16, the male genitalia in Figs 29 and 33; see Figs 15, 28 and 32 for <i>R. agnus</i>.</p> <p> So far this taxon was treated as a subspecies of <i>R. agnus</i>. Because the type localities of the two subspecies are only about 10 km away from each other, the authors of the original description hesitated to assign specific rank to <i>R. argaensis</i>. On the other hand, they found that the two taxa are obviously incapable of dispersal by flight (BILTON & FERY 1996: 924). This is why the authors suspected that both subspecies might be given specific rank following (future) genetic investigations and wrote "... but it would appear that these represent taxa on their way to speciation." (BILTON & FERY 1996: 928).</p> <p> Recently, such genetic investigations have been presented by ABELLÁN et al. (2013, appendices) and Ignacio Ribera (Barcelona, Spain) communicated privately that if both subspecies have "... enough morphological differences they can be upgraded to species... genetically they are very close, but well separated." In particular, the differences in the male genitalia are very distinct (see Figs 28 and 29), and thus the rank of <i>argaensis</i> is here elevated from subspecific to specific.</p> <p>The data of the specimens used for the genetic studies in ABELLÁN et al.

Oreodytes shorti SHAVERDO & FERY 2006
No full textNotes on Oreodytes shorti SHAVERDO & FERY 2006 This species was recently described from Mongolia and so far known only from three localities in a small region of the Changai mountain range, ca. 450 km WSW Ulaanbaatar, and ca. 25-75 km SW Tsetserleg (straight line). Since then specimens from a fourth, nearby locality became known with the following collecting data: Arkhangay Aimag, Bulgan Soum, Urd Tamir Gol, braid upstream of bridge, ca. 63 km SW of Tsetserleg, 47.11192N 101.01048E, 2066 m, 13.- 15.7.2004, A.E.Z. Short leg. All four localities are so close to each other that they can be represented by only a single square in the map (Fig. 19). For comparison, the male genitalia are given in Figs 9-10 and the male and female right fore legs in Figs 13-14.Published as part of Fery, H., P.

Type material: Holotype: Male: “ AUSTRALIA / WA Great Eastern Hwy, 80 km WSW Coolgardie “Scenic Lookout”, sandstone hill, Mallee, 12.I. 2000, in gnammas, Lars Hendrich leg. (loc. 16 / 162)” [white, printed]; “ HOLOTYPE Paroster ursulae sp. n. Hendrich & Fery des. 2007 ” [red, printed] {10} (WAM). Paratypes: 196 exs. with the same locality data as the holotype and a red printed paratype label (BNMH, CDB, CHF, CLH, NMW, SAMA, WAM, ZSM). Differential diagnosis: Habitus as in Figs 1, 4, 5; more stout and compact; distinctly larger than P. baylyi sp. n. Measurements: holotype: TL: 3.9 mm, TL-H: 3.6 mm, MW: 2.0 mm, TL/MW: 1.95, TL-H/MW: 1.80; paratypes: males (n = 20): TL: 3.7–4.2 mm (3.95 ± 0.36 mm), TL-H: 3.35–3.85 mm (3.64 ± 0.13 mm), MW: 1.95–2.2 mm (2.08 ± 0.08 mm), TL/MW: 1.81–2.03 (1.90 ± 0.05), TL-H/MW: 1.70–1.97 (1.75 ± 0.04); females (n = 20): TL: 3.4–3.9 mm (3.72 ± 0.13 mm), TL-H: 3.15–3.6 mm (3.43 ± 0.14 mm), MW: 1.75–2.1 mm (1.98 ± 0.09 mm), TL/MW: 1.80–2.17 (1.88 ± 0.08), TL-H/MW: 1.67–1.97 (1.74 ± 0.07). Species appearing much darker than P. baylyi sp. n., because yellowish areas on surface much less extended and brownish areas distinctly darker. Also underside somewhat darker; antennomeres almost entirely dark brownish beginning with fifth or sixth. Pronotum in dorsal view, behind anterior angles not diverging posteriorly, but sides more or less straight and parallel or slightly rounded and converging; thus, point of maximum width not at base, but often distinctly before base, and discontinuity in outline between pronotum and elytra rather prominent. Reticulation and punctation on upper surface similar to that of P. baylyi sp. n., but generally more distinct. Setae longer and at least on sides and anterior margin of pronotum more distinct. Variability: As in P. baylyi sp. n. mainly concerning extent of dark areas; on elytra in several specimens reaching until base, yellowish markings on pronotum often reduced on rather narrow stripes on sides and a band parallel to anterior margin before centre of disc; even this band often darkened medially. As in P. baylyi sp. n. often elytra with dark areas weakly lightened centrally. Male: Most characters as in P. baylyi sp. n., but median lobe larger, in ventral view rather narrow and more or less evenly tapering to truncate apex (Fig. 10); left paramere as in Fig. 13. Female: On average smaller than males (see Measurements). Reticulation of upper surface strongly impressed, in particular on elytra; thus, latter appearing very matt. Gonocoxae as in Fig. 16; gonocoxosternum large, less elongate (Fig. 19). Etymology: Dedicated to the senior author's mother Ursula Hendrich. Distribution: Only known from the type locality near Boorabbin, south-western Australia (Fig. 22). Probably more widespread in an area around Kalgoorlie and Coolgardie. Habitat: All beetles were collected in exposed, very small (1–1.5 m ²), shallow (up to 15 cm depth) and ephemeral puddles and pools on granite outcrops, by using various small nets and a kitchen strainer. Bottom consisting of sand of bare rock and stones (Figs 23–24). Most beetles were stationary in the middles of pools under flat stones, with a few hiding among rotten debris.Published as part of Hendrich, Lars & Fery, Hans, 2008, Paroster baylyi sp. n., P. ursulae sp. n.

Type material: Holotype: Male: 19.7. 2004 Turkey, Erzurum, Bingöl Mts., ca. 30 km SW Tekman, SSE Hamzalar, ca. 2150 m, little ponds, Ö. Köksal Erman leg., 39.23.09N 41.22.07E [printed], “ Holotype, Hydroporus neclae sp.n., Ö. Köksal Erman & H. Fery det. 2006 [red, printed] (NMW). Paratype: 1 female: same label data as the holotype, and with a red paratype label (CKE). Description. Habitus and size. Body narrowly elongate (Fig. 1), elytra almost parallel in anterior two thirds, widest shortly before middle; in dorsal view without discontinuity in outline between pronotum and elytra. The measurements give the following values: Holotype (male): TL: 3.6 mm, TL-H: 3.3 mm, MW: 1.75 mm, WP: 1.55 mm; TL-H/WP: 2.12. Paratype (female): TL: 3.5 mm, TL-H: 3.2 mm, MW: 1.65 mm, WP: 1.5 mm; TL-H/ WP: 2.13. Colour. Both specimens studied are slightly immature and, thus, the upper and ventral surface brown to dark brown. We assume, however, that mature specimens, as other similar species of the memnonius -group and in particular H. longicornis, are blackish brown or even black, with some parts being lighter brownish. Despite this immaturity, it can be recognised that the head has the anterior margin of clypeus lighter, as well as a rather broad transverse stripe on frons; the antennal articles are lighter brownish and darkened apically beginning with the fifth; most probably, the gula is lighter than the genae, and the sides of pronotum, at least the rim lighter than its disc; finally, the legs seem to be lighter brownish than most other parts of the venter. General surface sculpture. Entire surface covered by fine reticulation of small, more or less round meshes, however, in contrast to H. longicornis, and especially to H. melanarius, not appearing dull at all, but shiny throughout, even on apex of elytra. Head. Punctation simple and sparse, denser and coarser in two clypeal grooves between anterior margin of eyes; punctation on frons and vertex absent. Second article of antennae almost as long as third and fourth together; third and fifth articles of same length, fourth one shorter than these. Pronotum. Punctation near margins coarse and rather dense; inside hind angles with an impression, however, not nearly as deep as in H. obsoletus; here coarse punctures still denser and longitudinally prolonged in part. Disc of pronotum with only a few fine punctures, but a distinct scratch in its centre. Lateral margins in posterior half almost straight and converging anteriorly, stronger rounded anteriorly; lateral beading rather broad, more or less equal to half of diameter of antennal articles. Elytra. Punctation simple and almost evenly distributed, punctures rather coarse, only finer beside suture and on apex; on disc distance between punctures ca. 1.5 that of their diameter; puncture lines almost imperceptible. Beading of margins in lateral view distinct, epipleuron not visible to humeral angle; lateral margin weakly ascending to humeral angles. Epipleura with a few coarse punctures. Setae on elytra present, but extremely fine and almost imperceptible. Ventral surface. Sides of metasternum, metacoxae, and abdominal sternites with fine microreticulation, almost imperceptible in middle of third sternite, strongly impressed on last sternite, however, entire surface shiny. Large parts of venter provided with fine sparse yellowish setae, however these are rather indistinct. Prosternal process with a transverse ridge between procoxae, anteriorly not prolonged as a convexity, but flat and here provided with some very weak transverse grooves; shape of blade (behind procoxae) lanceolate, longitudinally carinate, sides narrowly flattened, here with a few coarse punctures and short setae; apex of process shortly rounded. Metasternum, metacoxae, and first two abdominal sternites with coarse punctures, however, centre of metasternum and areas right and left of it without punctures. Third to sixth sternite with punctures sparser and smaller. Metacoxal lines divergent anteriorly, ending short before posterior margin of metasternum; intralinear space with a few coarse and in part longitudinally prolonged punctures, in posterior half with distinct suberect yellowish setae. Posterior margin of each metasternal process almost straight, but both forming an obtuse angle (Fig. 12), thus, similar to those of H. melanarius (cf. Fig. 194 in Nilsson & Holmen 1995). Protibia provided with one line of coarse punctures. Male. Median lobe (Fig. 4) in ventral view almost evenly tapering to apex in apical half, not strongly narrowed before tip and with long process as in H. longicornis (compare Fig. 5) (the base of the median lobe is somewhat incomplete and deformed, probably due to the immaturity); paramere as in Fig. 7. Compare also the median lobe of H. melanarius (Fig. 6) and its paramere (Fig. 9) and that of H. longicornis (Fig. 8). First three protarsomeres—if at all—indistinctly broadened, protarsal claws more curved near base, otherwise straighter than in female. Female. Gonocoxosternum as in Fig. 11; gonocoxae (Fig. 10) without any angularity on inner side (cf. Figs. 78–80 in Fery 1999). Reticulation on head and pronotum slightly more strongly impressed than in males, nevertheless, surface not appearing dull. Protarsal claws evenly curved. Transverse grooves on base of prosternal process more distinct than in male holotype, this, however, possibly due to individual variation. Distribution. Turkey; known only from the type locality. Etymology. Named for Necla, the first name of the senior author's mother. Faunistics. Hydroporus neclae was found in an assemblage of about 10 ponds on a mountainous plain at an altitude of ca. 2150 m. These ponds have diameters of 5–30 m, and a depth of 1 m or somewhat more. The smaller ponds have well developed vegetation, the bigger ones less so. Other Dytiscidae found in these ponds are: Agabus bipustulatus (Linnaeus), A. caraboides Sharp, A. congener (Thunberg), A. glacialis Hochhuth, A. labiatus (Brahm), A. nebulosus (Forster), Platambus lunulatus (Fischer von Waldheim), Hydroporus erzurumensis (recorded with doubt since both specimens collected are very immature), H. kozlovskii, H. marginatus (Duftschmid), H. nigellus, H. palustris (Linnaeus), H. pubescens (Gyllenhal), H. thracicus, H. transgrediens Gschwendtner, Hygrotus lernaeus (Schaum), H. marklini (Gyllenhal), Scarodytes halensis (Fabricius), and Stictotarsus griseostriatus (De Geer). Discussion. Hydroporus neclae is most similar to H. longicornis and H. melanarius Sturm. It can be separated from the latter by the narrower habitus (cf. Figs. 1, 3), shape of the median lobe (cf. Figs. 4, 6), and the surface of the cuticle which is reticulate in both species, but dull in both sexes of H. melanarius, and shiny in H. neclae. Both the holotype and paratype have the TL-H more than twice as long as the WP, a feature which was used by Nilsson & Holmen (1995: 44) to separate H. longicornis from H. melanarius, and, thus, H. neclae 's body shape clearly fits more that of the narrowly elongate H. longicornis than that of the broader H. melanarius. The shape of the hind margins of the metacoxal processes is more or less the same in both species (Fig. 12). On a first glance, H. neclae could also be taken for a member of the H. longulus -group, but these have the hind margins of the metacoxal processes distinctly sinuate and the males in most cases have an asymmetric median lobe (cf. e.g. that of H. erzurumensis, Fig. 5 in Erman & Fery 2000). Hydroporus longicornis is similar to H. neclae with respect to the habitus (Fig. 2); the shape of the median lobe is also similar, but in ventral view much more distinctly narrowed before the apex in H. longicornis (Fig. 5). The latter also has the hind margins of the metacoxal processes slightly sinuate and distinctly protruded backwards in the middle (Fig. 13), while in the new species (Fig. 12) each margin is almost straight and together they form an oblique angle as in H. melanarius. In addition, the surface of H. longicornis is less shiny than that of H. neclae since the reticulation is more strongly impressed in both sexes. Notes: The drawings of the ventral aspect of the median lobe of H. longicornis in Schaeflein (1972: 31) and Nilsson & Holmen (1995: 54) are somewhat misleading since the narrowing before the apex is figured as too weak; this may be due to a slightly different angle of observation. Foster & Angus (1985: 12), Friday (1988: 83), and Fery (1999: 257) provide more appropriate figures of the median lobe since the apex is figured in a more or less perpendicular view. Finally, it shall be mentioned that we have also taken into consideration that the new species might be H. jacobsoni, a species which was described from the adjacent Caucasian mountains. The study of a female syntype revealed, however, that this latter species has strongly sinuate hind margins of the metacoxal processes and, thus, belongs to the longulus -group of genus Hydroporus.Published as part of Erman, Ömer Köksal & Fery, Hans, 2006, Hydroporus neclae sp. n. from north-eastern Turkey, a new member of the memnonius - group of Hydroporus Clairville (Coleoptera: Dytiscidae), pp. 39-47 in Zootaxa 1355 on pages 41-45, DOI: 10.5281/zenodo.17458

Additional material studied. The following six specimens probably belong to the new species, but are not treated as paratypes since they are females and I am not sure about their identity: 1 ♀, ‘ Armenia: N Yerevan (65), 24 km NW Hrazdan, bel.

Shaverdo & Schillhammer’ [printed] {12}, ‘ Hydroporus jacobsoni Zaitz., Shaverdo H. det. 2001’ [printed, hw Shaverdo in part] (CHS). 1 ♀, ‘Arm. Sevan Lake, Tsovagynch [= Tsovagyugh, ca. 40.63N 44.95E], 17.– 20.6.1981, Josef Král lgt.’ [printed] {11}, ‘ Hydroporus (Sternoporus) ♀?, jakobsoni [sic!] Zaitz, Wewalka 1983’ [hw Wewalka] (CGW). Differential diagnosis (given chiefly as differences from H. jelineki sp. nov.). More similar to H. jelineki sp. nov. and especially to H. hajeki sp. nov. than to H. jacobsoni. Maximum width of body more or less in middle of total length, distinctly before middle of elytral length. Discontinuity of body outline in dorsal view between pronotum and elytra weak, maximum width of pronotum at posterior angles. Punctation on disc of elytra more or less as in H. jelineki sp. nov., puncture lines distinct. Upper surface mostly black; only vertex of head, short stripe above insertion of each antennae and pronotal rim at posterior angles dark brownish. Venter with contrast between brownish appendages and body surface not prominent, more or less as in H. jelineki sp. nov. Darkening of middle of femora indistinct. JJ. Median lobe (Fig. 7) in ventral view with tip broader rounded than in H. hajeki sp. nov. (Fig. 6) and H. kryshtali (Fig. 8), and clearly much broader than in H. jacobsoni (Figs. 5–7). Paramere as in Fig. 14. Sucker cups on first tarsomere of pro- and mesotarsomeres present. ♀♀. Without conspicuous external differences to males. Gonocoxosternum and gonocoxae as in Figs. 20 and 25. Measurements. TL: 3.45–3.9 mm, MW: 1.65–1.85 mm, TL/MW: 1.97–2.14, IO/MP: 0.47–0.50. Variability. Some specimens also dark brownish next to suture of elytra and/or on entire pronotal rim; in a few specimens elytra in larger extent dark brownish. Punctation slightly varying in coarseness and density; sides of pronotum in a few specimens slightly more curved posteriorly. Distribution. So far known as endemic for Armenia, collected in the northern as well as in the southern part (Fig. 26). Biology. The following additional collecting data have been communicated by H. V. Shaverdo (see also SHAVERDO 2003): locality {10}: puddles on the banks of Kadzharan river, between large granite rocks (diameter ca. 3 m), plenty of Heracleum, bottom of puddles covered by decaying plant material. Locality {12}: puddle, caused by deep car tracks, probably longlasting, shaded, with much flooded vegetation (Ranunculus), in surrounding forest. Locality {13}: small spring fed puddles, bottom sandy-stony, thick layer of decaying leaves, grass, twigs and branches, banks with Caltha. Locality {14}: shallow stagnant area and flooded grassland, ca. 10 cm deep, near Marmaryk river; geology: granite with volcanic and crystalline components. Locality {15}: small river, fast flowing, ca. 2–5 m wide, exceedingly cold (ca. 5°C), most aquatic beetles from small accompanying rivulets with dense aquatic vegetation (incl. moss); geology: volcanic (basalt, tuff). Etymology. The species is named after my colleague and friend Helena V. Shaverdo (Vienna, Austria), who kindly submitted her material for study (noun in apposition in the genitive case).Published as part of Fery, Hans, 2009, New species of the Hydroporus longulus-group from Iran, Armenia and Turkey with a synopsis of the group (Coleoptera: Dytiscidae), pp. 529-558 in Acta Entomologica Musei Nationalis Pragae 49 (2) on pages 547-549, DOI: 10.5281/zenodo.532017
