Aemona infuscata Devyatkin & Monastyrskii 2008, stat. rev.
No full textAemona infuscata Devyatkin & Monastyrskii, 2008 stat. rev. (Figs. 11A, B) Aemona infiscata Devyatkin & Monastyrskii, 2008 was originally described as a subspecies of A. tonkinensis Rothschild, 1916. The status of the latter taxon was established by Devyatkin & Monastyrskii (2008) showing that A. amathusia (Hewitson, 1868) and A. tonkinensis are separate species. Aemona infuscata is smaller than A. tonkinensis. The hindwings are ochreous brown and darker than the forewings with faint submarginal lunules. The original description does not describe genitalia. However, since the description of infuscata, we have been able to examine the genitalia of many specimens and find that the phallus has a conspicuous, sclerotised rib, the centre of which bears a few spines (Figure 11A, B). In A. infuscata, only the distal margin of the clasper’s tip is covered by spines, while in A. tonkinensis spines cover around half of tip. This difference, in concert with differences in size and wing colouration demonstrate that infuscata should be elevated to the species level.Published as part of Monastyrskii, Alexander L. & Lien, Vu Van, 2021, New taxa and new records of butterflies from Vietnam (Lepidoptera, Papilionoidea), pp. 486-510 in Zootaxa 5048 (4) on page 502, DOI: 10.11646/zootaxa.5048.4.2, http://zenodo.org/record/555659

Description. ♂ Forewing length: 29.5–31 mm. Forewing strongly elongated towards the apex. Upperside: ground color greyish brown; forewing postdiscal band with the paler outer border vestigial; forewing yellow subapical spots in cells M 1 and M 2 present; forewing with a weak and slender orange marginal line; hindwing postdiscal spots with the yellowish iris narrower and separated from each other by veins. Underside: ground color pale brown with markings similar to those of L. manzorum; reddish fasciae and bars narrow. Male genitalia. (Figs: 17, 18, 25 c) Uncus: very long and strongly bent downwards. Gnathos: base normal in width, then gradually tapering towards the end; it is bent downwards near the base, and bent upwards near the apex. Valva: apical part elongated distally as a tongue-shaped lobe; apex more or less rounded; dorsal edge weakly humped in apical half; central part of ventral edge angular. ♀ Forewing length: 33–34 mm. Similar to male. Upperside: forewing postdiscal band with well visible outer yellowish border which is vestigial in male. Underside: the same as in male. Diagnosis. L. sisii may be distinguished from L. manzorum by the combination of the following characters: a) upper surface of forewing with paler outer markings of postdiscal band vestigial, but prominent in L. manzorum; b) upper surface of hindwing with series of yellow ringed submarginal slender spots separated from each other; these spots somewhat wider and confluent in L. manzorum; c) under surface of both wings with reddish fasciae and bars much narrower than in L. manzorum (e.g. width of hindwing postdiscal fasciae in space 3: 0.9 –1.0 mm in this new species, 1.5–1.6 mm in manzorum); d) uncus longer than that in L. manzorum; e) gnathos bent downwards near the base, whereas it is bent upwards in L. manzorum; f) apical part of valva much more elongated than that in L. manzorum. Etymology. The specific name sisii is named after Mr. Si Si from Chengdu, a good friend of the first author. Distribution. China (Sichuan, Chongqing, SE Gansu, S. Shaanxi, Hubei, Jiangxi).Published as part of Lang, Song-Yun & Monastyrskii, Alexander L., 2016, Description of two new species of the Lethe manzorum - group (Lepidoptera, Nymphalidae, Satyrinae) from China, pp. 453-462 in Zootaxa 4103 (5) on pages 454-455, DOI: 10.11646/zootaxa.4103.5.3, http://zenodo.org/record/26487

No full textRagadia latifasciata crystallina Monastyrskii & Vu, subspec. nov. (Figs. 10C–F) Description: Male: length of forewing: HT 21 mm; PTs 23, 24, 21, 20 mm. ♂ Upperside (Figure 10C–D). Ground colour of both wings is black with two whitish bands on both wings; forewing with very wide postdiscal band which is broad at dorsum and gradually tapering toward the apex and ending near vein M 1; the thin subterminal fascia starting from vein 1A+2A and ends at vein M 3; terminal fascia barely noticeable; poorly visible basal and sub-basal fasciae starting from vein 1A+2A and extending to subcostal vein; hindwing white discal fascia starting from costal edge and gradually narrowing at dorsal edge; basal and subbasal fasciae very poor visible; narrow submarginal whitish fascia prominent. Underside (Figure 10E–F). Ground colour of both wings blackish brown. Forewing pattern of fasciae similar to upperside, but all whitish fasciae prominent, and postdiscal whitish band reaches costal edge near apex; submarginal blackish area bears series of single yellow ringed ocelli from the cell R 4 to Cu 1a; there are two ocelli in the cell Cu 1b; every ocellus has a bluish pupil surrounded by a thick black ring. Hindwing pattern of fasciae similar to upperside, but all whitish fasciae prominent; broad submarginal blackish brown area bears series of oval ocelli in cells Cu 1b -Rs except cell M 1; the cell Cu 1b includes two ocelli. Female: length of forewing: 2PTs 20, 24 mm. ♀ (Figures 10E–F). Both upperside and underside wing pattern similar to that in the ♂. Male genitalia (Figure 9B) similar to the nominate subspec. latifasciata and other subspecies including critias and cristata from W. China, N. Vietnam and Thailand (Lang, 2017). Diagnosis. The new subspecies differs from the nominate subspecies and subspecies critias in the following characters: 1. Compared to the nominate subspecies, both sexes of crystallina have much narrower whitish postdiscal bands on both wings; 2. Similar to the nominate subspecies, the new taxon lacks an ocellus only in cell M 1, while subspecies critias lacks submarginal ocelli in cells M 1 and M 3.

Previously this rare species was recorded by A. de Cooman in 1928 from Hoa Binh province (north-western Vietnam) (Monastyrskii, 2019). This specimen resembles ssp. japonica Ménétriés, though populations from S. China are similar to ssp. rudra Moore. The specimen collected in Ha Giang province (eastern side of N. Vietnam) is similar to ssp. rudra.Published as part of Monastyrskii, Alexander L. & Lien, Vu Van, 2021, New taxa and new records of butterflies from Vietnam (Lepidoptera, Papilionoidea), pp. 486-510 in Zootaxa 5048 (4) on page 507, DOI: 10.11646/zootaxa.5048.4.2, http://zenodo.org/record/555659

Faunis indistincta subsp. luctus Monastyrskii & Vu 2021, subspec. nov.
No full textFaunis indistincta luctus Monastyrskii & Vu subspec. nov. (Figure 13, 14) Description: Male: length of forewing: HT: 45.0 mm; PTs: 46.0; 45.0; 46.0 mm; antennae dark brown (22.0 mm). Forewing upperside (Figure 13A): ground colour uniformly grey; area from termen and apex to postmedian and subcostal penetrating into discal cell uniformly blackish brown; there is a smooth transition from greyish black to bright grey in the postmedian area; series of small whitish subterminal spots is lined from cell R 4 to Cu 1a; cilia dark brown. Hindwing upperside (Figure 13A): ground colour uniformly grey with blackish brown bordering from termen to subterminal area and smooth transition to greyish colour; there is a series of small and subtle whitish subterminal spots from cell Rs to Cu 1a; cilia dark brown. At base of cubitus there is hair tuft touching a small spot of specialised scent scales on underside of forewing base. Forewing underside (Figure 13B): Ground colour dark brown with three darker brown fasciae located within discal cell (submedian) and at postmedian and subterminal areas; series of subterminal small whitish spots located in a row from cell R 4 to Cu 1a. Hindwing underside (Figure 13B): ground colour is similar to the forewing; the hindwing pattern includes submedian straight fascia extending from Sc+R 1 to Cu 1b; postmedian fascia extending from Sc+R 1 to Cu 1b and subterminal fascia from Rs to Cu1b; series of small whitish subterminal spots extending from cell Rs to Cu 1a Female: unknown Diagnosis. The new taxon collected in Lao Cai Province resembles members of the Faunis aerope speciesgroup distributed in southern China and northern Vietnam. The most distinctive character of F. indistincta Mell is the male genitalia structure which vaguely resembles that of F. aerope: relatively short and curved valvae with apex covered by dense spines (Figure 14A, C–E). Faunis indistincta luctus is similar to recently the described species Faunis caelestis Monastyrskii & Lang, 2016 (Figure 13C–D). Both species have similar wing patterns on the undersides of both wings, though in F. caelestis the ground colour is paler. The upperside of F. indistincta luctus is similar to F. aerope yunnanensis Brooks and F. caelestis, though the new taxon has broad black borders on both wings (Figure 13A) and distinctive male genitalia (Figure 14A, C–E). The female genitalia structures in species of F. aerope group are also distinctive; however, this character cannot be used in the current study because the female of F. indistincta luctus has not yet been discovered. Type material. Holotype: NORTHERN VIETNAM, ♂, Lao Cai province, Hoang Lien N.P., Cong Troi pass (Tram Ton ranger station), 20.V.2011; evergreen mountain forest at ~ 1,900 m; VVL leg.; Paratypes: 3♂: same data as holotype. The holotype and two paratypes will be deposited in the VNMN (Hanoi); one paratype will be deposited in the NHM (London). Distribution and habitats. The new taxon has been recorded only at Hoang Lien National Park in the vicinity of Fan Si Pan peak and the forest ranger station at elevations around 2,000 m.Published as part of Monastyrskii, Alexander L. & Lien, Vu Van, 2021, New taxa and new records of butterflies from Vietnam (Lepidoptera, Papilionoidea), pp. 486-510 in Zootaxa 5048 (4) on pages 505-507, DOI: 10.11646/zootaxa.5048.4.2, http://zenodo.org/record/555659
Ragadia latifasciata subsp. cristata Monastyrskii & Vu 2021, subspec. nov.
No full textRagadia latifasciata cristata Monastyrskii & Vu, subspec. nov. (Figs. 8, 9) Description: Male. Length of forewing: HT 22.5 mm. ♂ Upperside (Figure 8A). Ground colour of both wings blackish with a broad, white postdiscal band broadened at dorsum on the forewing and to the costal edge on the hindwing; on the forewing the band ends at vein M 1. Basal and sub-basal whitish fasciae on the forewing are indistinct. Underside (Figure 8B). Both wings ground colour blackish with broad postdiscal white band and well distinct basal, sub-basal and submarginal whitish fasciae. Forewing with series of submarginal eye spots including spots in cells from Cu 1b (double spot) to R 4 (single spots in all other cells); hindwing with series of subterminal eye ringed spots spreading from cell Cu 1b to Rs; spot in cell M 1 is absent. Female: length of forewing: PTs 24.0; 24.5; 25 mm. ♀ (Figure 8C, D) The female is slightly larger than the male with a convex terminal edge on the forewing; wing patterns on both surfaces are similar to that in the male. The most conspicuous character is the absence of an eye spot in cell M 1 of the hindwing. Male genitalia. (Figure 9). Uncus long, slender and gradually tapering at tip; uncus in 1.5 times longer than tegumen and pointed towards the tip; gnathos is ½ of the uncus length and pointed towards the end; saccus relatively long but shorter than valvae; phallus long with hooked bend at the tip; valvae elongated with the round apex and small and small spike at upper side. Diagnosis. Specimens recently collected in Ha Giang province are similar to the ♂ and ♀ R. latifasciata type specimens described from Moupin [Baoxing, Sichuan] (W. China) and deposited in the NHM. It is definitely a rare species that has not been collected or mentioned since Leech’s (1892–94) publication of the species description. Recently, the taxon latifasciata was misidentified as a subspecies of R. crisilda in Lang (2017) and has been regarded as a form of R. crisilda. However, type specimens of latifasciata from China and the recent discovery from Ha Giang bear no resemblance to R. crisilda, which has a complete series of submarginal spots on the hindwing underside. The wing patterns of R. latifasciata are similar to those of R. critias Riley & Godfrey, 1921 from central Vietnam, which can be easily distinguished from specimens from the type locality (N. Thailand) and from Southern China (Yunnan province, near the border to Vietnam). At the same time, the male genitalia of latifasciata from N. Vietnam and critias from C. Vietnam, Thailand and S. China show high similarity (Figures 10). Considering these observations, we suggest a revision of these species. Type material: Holotype: NORTHERN VIETNAM, ♂ Ha Giang province, Dong Van district, Yen Minh commune, VI.2015, local collector leg. Paratypes ♀ the same location and date as holotype, local collector leg.; ♀ the same location as holotype, VI.2009, HVT leg.; ♀ Ha Giang province, IV–V.2007, local collector leg. Distribution. The new taxon is known only from Ha Giang province (northern Vietnam), though it may occur in southern China.Published as part of Monastyrskii, Alexander L. & Lien, Vu Van, 2021, New taxa and new records of butterflies from Vietnam (Lepidoptera, Papilionoidea), pp. 486-510 in Zootaxa 5048 (4) on page 500, DOI: 10.11646/zootaxa.5048.4.2, http://zenodo.org/record/555659
