No full textXestia rimas Gyulai, Ronkay & Saldaitis sp. n. (Figs. 4, 12–15) Type material. Holotype: Male, China, N-Sichuan, road Songpan - Jiuzhaigou, 3000 m, 3308.770’N, 10343.624’E, 23.vii.2011, leg. A. Floriani & A. Saldaitis, slide No PGY 3213m (coll. Peter Gyulai, later in Hungarian Natural History Museum, Budapest, Hungary). Paratypes: 5 males, with the same data as the holotype, colls Peter Gyulai, Alessandro Floriani (Milan, Italy) and Gintaras Rimas (Bendoreliai, Lithuania) Slide No PGY 2893m. Diagnosis and Description. Wingspan 36–38 mm. The new species with its prominent morphological autapomorphies represents a unique lineage within the entire Holarctic genus Xestia s. l. Externally it slightly resembles Rhyacia mirabilis Boursin, 1954 and R. admiranda Gyulai & Ronkay, 2001, but has a less robust body and broader trigonical forewings with a short apex and straight outer margin. The dark bluish-ashy grey forewing ground colour distinguishes it from the two bright greenish Rhyacia species; the orbicular and reniform stigmata are lighter than the ground colour, but not so dark as those of R. mirabilis and R. admiranda. Xestia rimas (Fig. 3) is also somewhat similar to certain other Holarctic larger, greyish coloured members of the subgenus Pachnobia Guenée, 1852 (formerly Anomogyna Staudinger, 1871; was synonymised with Pachnobia, Lafontaine, 1998) but is easily separable by the almost unicolorous dark bluish ashy grey forewing ground colour, the unusual light ochreous suffusion of the basal field, the large, regular, light ochreous-grey filled orbicular stigma and the conspicuous small, dark ochreous spot in the indistinct, darkened reniform stigma. Antennae filiform; legs blackish; hindlegs with a single long and two shorter spines; head, thoracic pubescence and palpi light ashy grey; palpi with black underside; abdomen light brown; antemedial line double, wavy; postmedial line simple, arcuate and serrated; both crosslines diffuse, blackish-grey; subterminal line obsolescent, with blackish trigonical costal patch and black arrowheads at inner side; hindwing brownish-grey, with darker cellular discal spot and wavy medial line; cilia of both wings ashy grey. The male genitalia (Figs. 12–15) are typical of the subgenus Pachnobia but the distal part of the valva is more elongated, terminally bifurcate, and resembles those of some species of the subgenus Raddea Alpheraky, 1892 (formerly Erebophasma Boursin, 1963; was synonymised with Raddea, Lafontaine 1998 and Kononenko et al. 2012), especially Raddea hirsuta (Chen, 1985). The specific features of the male genitalia of X. rimas are the large, broadly calyciform juxta, with deep, laterally sinuous V-shaped dorso-medial incision; particularly distally elongated, terminally asymmetrically bifurcate, pointed valva; medium-large, thick and basally strongly curved, apically acutely pointed harpe; large knot-shaped carinal plate, appearing rather like a basal cornutus; the dorsally recurved, ample vesica with sclerotised, slightly serrated subbasal plate. Female unknown. Bionomics and Distribution. The six males were collected at ultraviolet light on 23 July 2011 in Sichuan Province in a remote area located at the southern end of the Minshan mountain range (Fig. 5). The collecting area is near Jiuzhaigou National Park. The climate in the valley is cool, with a mean annual temperature of 7.2 degrees C and total annual rainfall of 661 mm (80% of which occurs between May and October). Jiuzhaigou's ecosystem is classified as temperate broad-leaved forest and woodlands, with mixed mountain and highland systems. Among other summer noctuid species collected at the time were Haderonia albirena (Draudt, 1950), Diphtherocome pallida (Moore, 1867), Xestia morandinii Gyulai, Ronkay & Saldaitis, 2011, Papestra florianii Gyulai, Ronkay & Saldaitis, 2011.

The new species is close to H. praecipua and H. yakobsoni. It externally differs from H. praecipua by paler, ochreous-brown colouration of forewings; from H. yakobsoni it differs by dark ochreous-brown colouration of forewings, much darker, brownish hindwing and more expressed pattern with brown, almost straight postmedial line. The male genitalia of H. shchetkini differ from H. praecipua by narrower uncus with obtuse apex, somewhat smaller cucullus, somewhat shorter digitus, broader vesica and thinner claw-like cornutus with more acute tip; from H. yakobsoni differ by pointed apex of uncus, less separated cucullus, shorter digitus, subbasally broader vesica, longer and thinner cornutus with more pointed tip; from H. delattini differ by smaller juxta, larger and more separated cucullus, shorter digitus and costal process and the presence of only one cornutus in the vesica. The female genitalia differ from H. yakobsoni by shorter apophyses anteriores, narrower antrum and semilunar sclerotised plate of appendix bursae. Description. Adult (Figs 6–9).

I. & A. Floriani & A. Saldaitis; coll. P. Gyulai (Miskolc). Slide No. GYP 2435m Paratypes: 2 males, 2 females, with the same data; slide Nos GYP 2398m, GYP2482 f. The paratypes are deposited in the collections of ASF, GYP, GBG / ZSM and NRCV. Diagnosis and description. Forewing length 16.5–18.0 mm. External morphological features and genitalia place the new species closest to Palaeamathes harpegnoma (Hreblay & Ronkay, 1998). Despite similarities in forewing ground colour (brown, brown-red) with the single worn P. harpegnoma specimen, P. serrulata can be distinguished by having more elongated forewings, an antemedial crossline that is not oblique and a narrower reniform stigmata that has a conspicuously different shape forming a lying V-form pointing toward the basal part of forewing. In the male genitalia of the new species the cucullus is slighter longer, the apical process of the bifurcated harpe is longer, and the medial incision of the juxta is smaller. The vesica has two tiny wide-based cornuti situated in close proximity subbasally, while in P. harpegnoma the smaller cornutus is distally positioned. Distinguishing female genitalia characters, in comparison with the other known Palaeagrotis, are as follows: ostium bursae is wide calycular, with a small posterio-medial incision on the outer belt-like sclerotised lamella; the wall of ductus bursae has a visible characteristic, longitudinal tongue-like sclerotised lamella; the appendix bursae is basally broad and the corpus bursae is sac-like. Distribution and biology. Only known from the Litang area of China's Sichuan province on the east part of the Tibetan plateau. All specimens were collected in mid July at an altitude 4000 m. Both males and females are attracted to light but appear to have a local distribution as P. serrulata was discovered in one small valley near Litang. The new species was uncommon in the alpine grasslands zone where it flies with other rare high altitude moths such as the arctiids Platarctia souliei (Oberthür, 1911) and Murzinowatsonia x-album (Oberthür, 1911). Etymology. The name refers to the serrated distal part of the harpe.Published as part of Gyulai, P., Ronkay, L. & Saldaitis, A., 2011, New Noctuidae species from China (Lepidoptera, Noctuoidea), pp. 46-52 in Zootaxa 2896 (1) on pages 47-48, DOI: 10.11646/zootaxa.2896.1.5, http://zenodo.org/record/528513

Cerastis aspira Gyulai, Ronkay & Saldaitis 2011, sp. n.
No full textCerastis aspira Gyulai, Ronkay & Saldaitis, sp. n. (Figs. 1, 2, 9–11) Type material. Holotype: Male, China, W. Sichuan, Kangding, near Zheduo Pass, 30°17.022'N, 101°50.256'E, 13. iv. 2010, 3230 m, leg. A. Saldaitis, coll. P. Gyulai, slide No. GYP 2431m. Paratypes: 13 males, 5 females, with the same data. The paratypes are deposited in the collections of AFM, ASV, DNK, GBG / ZSM, GRB, HHP, NRCV and GYP. Slide Nos. GYP 2403m, GYP2480 f. Diagnosis and description. Forewing lengths of 16–17 mm and 15mm for the male and female, respectively. The forewing differs from all other Palearctic congeners being the noctuid maculation lighter reddish-brown, than the ground color and forewing pattern differs by the lower parts of the orbicular and reniform stigmata confluent on the main vein forming a characteristic broad V. The forewing is more similar to four North American specie s (C. cornuta Grote, 1874, C. robertsoni Lafontaine & Crabo, 1997, C. enigmatica Lafontaine & Crabo, 1997, and C. gloriosa Lafontaine & Crabo, 1997) but can be distinguished by the shape of the crosslines. Compared to the Neartic taxa (Lafontaine, 1998) the male of the new taxon has narrower valvae terminally, a simple non-twisted vesica without subbasal cornutus, and a twin terminal cornutus. In the female genitalia the appendix bursae of C. aspira is simple (not coiled) and is considerably smaller than in the four Nearctic species; the shape and sclerotization of ostium bursae is different and the otherwise longer ductus bursae has different sclerotized parts. These genitalic differences also apply to the Palaearctic species, however similarities with C. leucographa ([Denis & Schiffermüller], 1775) including tubular, helicoidally twisted vesica and the lack of a subbasal cornutus indicate a possible grouping with that species. Recent faunistic lists still include C. leucographa in the genus Cerastis Ochsenheimer, 1816 but suggestions to put it into a distinct genus began with Heinemann (1859), who established the genus Sora for Noctua leucographa, suggested it was distinct. Subsequently, Tams (1939) stated the homonymy of Sora and gave the replacement name Gypsitea (see Nye, 1975), and both Beck (1992) and Fibiger (1997) considered the possibility of a new taxon. There are clear male genitalic differences between the two allied species: the vesica of the new taxon is not twisted and bears two much shorter and wider basally coincident terminal cornuti, the terminal part of the valva is elongated, the basal part of the harpe is broader, distally thorn-like and dorsally curved, the juxta is differently shaped, and the medial incision is broadly U-formed. Distribution and biology. Only known from the Kangding area of China's Sichuan province on the east edge of the Tibetan plateau. All specimens were collected in mid April at an altitude of 3200 m; both males and females are strongly attracted to light even during periods of snowfall but appear to have a local distribution, as Cerastis aspira was discovered only in the Kangding Valley near Zheduo Pass. The new species was uncommon in the shrubby transition between the mountain primary mixed forests and alpine grassland zones. It flies with other early spring moths such as Hyalobole nigripalpis (Warren, 1911) or overwintering Dasypolia (Dasypolia) bicolor Hreblay & Ronkay, 1995.Published as part of Gyulai, P., Ronkay, L. & Saldaitis, A., 2011, New Noctuidae species from China (Lepidoptera, Noctuoidea), pp. 46-52 in Zootaxa 2896 (1) on pages 46-47, DOI: 10.11646/zootaxa.2896.1.5, http://zenodo.org/record/528513

Slide Nos: PGy 3060m, PGy 3064m, PGy 3065m, PGy 3555m. Diagnosis and description. Wingspan 29–32 mm. Morphologically the new species resembles its only known closely allied taxon, Xestia aplectoides (Draudt, 1963) which was described from Yunnan. The new species can be separated from this sister taxon by its blackish-dark brown palpi, slightly broader, more unicolorous brownish-grey forewings, and the slight reddish-brown suffusion of the medial field apparent on fresh specimens. By comparison, X. aplectoides (Fig. 3) has lighter palpi with a white edge and pure grey forewing ground colour with dark greyish (sometimes blackish) suffusion. The transverse lines of X. elisabetha (Figs. 1, 2) are finer, generally simple and more obsolescent with only the antemedial line clearly visible and the wavy postmedial line less serrated. External diagnostic features are clearly recognizable only in newly emerged specimens so that further genitalic investigation is required for worn individuals. The female is still unknown. The male genitalia (Figs. 6–9) are most similar to those of X. aplectoides (Figs. 10, 11) but with certain conspicuous differences, as follows: the uncus of the new species is much broader and differently shaped distally, being lanceolate and pointed apically; the vinculum is about half as long as in X. aplectoides; the juxta is more elongated-triangular dorsally; the valvae are less elongated, having larger flap-like terminal extensions on the ventral side; the vesica is ventrally recurved, ample, with two (basal and subbasal) cornuti fields with numerous sparsely arranged cornuti compared to X. aplectoides which has a larger basal cornutus or a short, slightly serrated sclerotised field with 1–2 tiny cornuti. Bionomics and Distribution. Known only from the Barkam and Moxi areas in northern Sichuan Province on the east edge of the Tibetan plateau. Nine males were collected at lights on cold nights on 21, 23 September 2011 and 7 October 2012 at an elevation of 3300–3950 m in shrubby, swampy areas. Sympatry with X. aplectoides is unknown, but the latter is generally on the wing somewhat later through October in Yunnan and West Sichuan provinces. Etymology: Dedicated to Mrs. Elisabeth Rau (Grafing, Germany) for her contributions to entomology.Published as part of Gyulai, P., Ronkay, L. & Saldaitis, A., 2013, Two new Xestia Hübner, 1818 species from China (Lepidoptera, Noctuidae), pp. 96-100 in Zootaxa 3734 (1) on page 96, DOI: 10.11646/zootaxa.3734.1.12, http://zenodo.org/record/526885

Diagnosis – Ctenoceratoda scotosparsa is on average the smallest species of the khorgossi -group with its wingspan 33–38 mm. It is most closely related to C. argyrea (Figs 7–8) but is smaller in size and more narrow-winged, the light ochreous-grey ground colour of the forewing is irrorated with whitish and blackish-brown scales, and the entire wing is less shiny than in C. argyrea. The maculation is also different: reniform stigma finely blackish defined, with blackish-brown filling and an L-shaped whitish spot basally, without “pipeshaped” elongate whitish stripe like in C. argyrea and C. khorgossi. The claviform stigma is unicolorous blackish-brown, being very different from those of all other species of the species-group (and the whole genus). The inner side of the subterminal line is followed by sharp black arrowheads. The hindwings are more unicolorous and darker than in all related species. The male genitalia (Figs 43–46) are also proportionally smaller than in the related species, the “head” of the cucullus is not inflated than in C. argyrea and more rounded than in C. cyanochrea (Figs 47–48). The ampulla is relatively broad, slightly curved and rounded terminally; the fascia of cornuti in vesica is shorter than in the related species, as well as the appendix bursae in the female genitalia (Fig. 42). Distribution and bionomics. Mostly unknown. The type-series was collected at medium-high altitude of the Mongolian Altai Mts; the flight period is the early summer.Published as part of Varga, Zoltán, Gyulai, Péter, Ronkay, Gábor & Ronkay, László, 2018, Review Of The Species Groups Of The Genus Ctenoceratoda Varga, 1992 With Description Of Four New Species And A New Subspecies (Lepidoptera, Noctuidae), pp. 51-74 in Acta Zoologica Academiae Scientiarum Hungaricae 64 (1) on page 63, DOI: 10.17109/AZH.64.1.51.2018, http://zenodo.org/record/573463
Loxopamea augustasi Gyulai & Saldaitis, 2015, sp. n.
No full textLoxopamea augustasi sp. n. (Figs 1, 2, 7, 11–13) Type material. Holotype: Female (Figs 1, 11), China, North Sichuan, road Jiuzhaigou-Songpan, 2900 m, N 29 ° 87.340 ’, E 102 ° 30.970 ’, 27.viii. 2014, leg. Floriani & Saldaitis; slide No PGY 4131 f (coll. PGM, later to be deposited in the HNHM). Paratypes: 2 males, 6 females (Figs 2, 7, 12, 13), with the same data as the holotype; slide Nos PGY 4163m, PGY 4088 f, PGY 4107 f (colls AFM & ASV). Diagnosis and description. Wingspan 29–31 mm, length of forewing 14–16 mm. The new species is the sister species of the poorly known Loxopamea albistigma Hreblay & Ronkay, 1998 (Hreblay et al., 1998: pp 146–147 and p. 862, figs. 113, 114 and Zilli et al. 2009: p 117, pl. 33, figs 1, 2; pl. 33, figs 9, 10), however, the two species are much dissimilar externally. The vesture of the head and body, the ground colour of the forewing in the L. augustasi sp. n. are the various shades of ochre brown, the middle and the marginal area are the darkest, however the vertex, the collar and the basal area of forewing are with rufous tone. The orbicular spot is tiny, circular; the reniform stigma and the claviform spot are regular and also brown, with some white or ochre scales in the reniform stigma. The antemedial and postmedial crosslines are clearly visible, defined by blackish and ochreous-brown scales. The ground plan of the wing pattern and coloration of the wings resembles apparently Loxopamea brunnea (Leech, 1900), which is less close relative species by the genitalia armatures; in the new species the forewing apex is more elongated, the ground colour much lighter and unicolorous and the transversal crosslines are more distinctly marked and somewhat differently shaped, the lunulate discal spot in the hindwing less defined or conjectural. By comparison the closest relative L. albistigma, the distinctive external features for the separation of the two species are as follows: L. augustasi has much more unicolorous, less variegated, ochre brown ground colour of the forewing, however darker middle area; regular, brown orbicular spot and claviform stigma; almost lack of the white filling in the reniform stigma, more distinctive transverse lines and the rufous tone of the vertex, collar and the basal area of forewing. The new species is somewhat smaller on average, with the wingspan 29–31mm (versus 32–34 mm of L. albistigma). The distribution of the two sister-species is not known exactly due to the very few found specimens, therefore the collecting locality cannot help in the identification. However, the differences between the genitalia of the two species are remarkably large in case of both sexes, therefore the study of the genitalia can easily confirm the species identity of the examined specimen(s). The armature of both male and female genitalia clearly indicates that the sister species of L. augustasi is the L. albistigma and not the externally more similar L. brunnea. Male genitalia. (Fig. 7) The genitalia ground plan of the new species apparently is almost the same as in the known species of Loxopamea, but the armature of the vesica having two, almost parallel longitudinal cornuti field with a great number of spinules clearly indicates the close relationship to L. albistigma (see Hreblay et al. (1998): 181, gen. fig. 161 and Zilli et al. (2009): 345, gen. fig. 127). L. augustasi can be easily separated from its twin species by a series of conspicuous differences. The key features are in the shape and configuration of the digitus, juxta, vesica and in the length of aedeagus. The digitus is much shorter in the L. augustasi, cca. half sized; the juxta is much lower, weak and broadly cup-like, ventrally rounded, with two dorso-lateral long appendages; the vinculum longer, the aedeagus much shorter and ventrally curved, medio-distally with a strongly sclerotized, finely serrate-toothed field; the vesica is shorter, the two, almost parallel longitudinal cornuti field with a great number of spinules are much shorter and of almost the same length, positioned subbasally and not distally. Female genitalia. (Figs 11–13) The key features are in the shape and configuration of the ostium-antrum complex, the ductus bursae, and the appendix bursae. L. augustasi (Figs 11–13) differs strikingly from L. albistigma (see Hreblay et al. (1998): 181, gen. fig. 164 and Zilli et al. (2009): 345, gen. fig. 127), by its less calycular, broader, more robust ostium-antrum complex; posteriorly broaden, longer, stronger sclerotized ductus bursae; the stick-like, more ample, larger, almost evenly broad, less sclerotized-ribbed appendix bursae and the more globular corpus bursae. Bionomy and distribution. The two males and seven females were collected at ultraviolet light on 27 August 2014 in southwest China Sichuan province in a remote, area located at the southern end of the Minshan mountain range. The collecting area is near the incomparable Jiuzhaigou National Park. The climate in the valley is cool, with a mean annual temperature of 7.2 °C and total annual rainfall is 661 mm, 80 % of which occurs between May and October. Jiuzhaigou's ecosystem is classified as temperate broad-leaved forest and woodlands, with mixed mountain and highland systems. The 300 km ² heart of this scenic area is covered by virgin mixed forests including oaks and endemic varieties of rhododendron and bamboo. Etymology. The new species is named after the son of second author, Augustas Saldaitis (Vilnius, Lithuania) for his enthusiasm and patience during the China trip.Published as part of Gyulai, Peter & Saldaitis, Aidas, 2015, Two new species of the genus Loxopamea Hreblay & Plante 1995 (Lepidoptera: Noctuidae) from China, pp. 345-350 in Zootaxa 4032 (3) on pages 345-349, DOI: 10.11646/zootaxa.4032.3.12, http://zenodo.org/record/23415
