Review of Semagystia monticola species group (Lepidoptera, Cossidae: Cossinae) with description of four new species from Central Asia

Abstract

The article gives a revision of the Semagystia monticola (Groum-Grshimaïlo, 1890) species group (Lepidoptera, Cossidae, Cossinae). The group comprises nine valid species. Detailed data on the distribution of all the species are provided. Four new species from Central Asia are described: S. churkini Yakovlev & Shapoval, sp. n. (Type locality: Kyrgyzstan, Moldo-Too Range, Kichine-Kindyk River), S. fomichevi Yakovlev & Shapoval, sp. n. (Type locality: Tajikistan, Eastern Pamir Mts., Zulumart [Palangguzar] Mt. Rg.), S. toropovi Yakovlev & Shapoval, sp. n. (Type locality: Kirgizia, Tschatkal Mt., Sary-Chelek lake), and S. uvaydo Yakovlev & Shapoval, sp. n. (Type locality: Tajikistan, Darvaz Mts., Khozratishoh Range, Khaburobot pass). The article is illustrated with imagoes of specimens from different localities and male genitalia of all new species.

Introduction

In the recent years, we have started the revision of Carpenter-Moths of the tribe Endagriini Duponchel, 1844 (Yakovlev et al. 2016, 2020, 2022; Yakovlev 2022; Yakovlev & Naydenov 2022), including over a hundred taxa of the species group, most of which are hard to identify. The tribe representatives are widely distributed in Middle East and Central Asia, also in Europe, North Africa, Southern Urals and Western Siberia (Daniel 1962; Yakovlev 2011; 2015).

The genus Semagystia Schorl, 1990 (type species, by original designation: Endagria agilis Christoph, 1884) includes 19 species (Schoorl 1990; Yakovlev 2011, 2014, 2015; Yakovlev et al. 2015), most of which are distributed in Central Asia and Afghanistan, only two of them (S. cuhensis de Freina, 1994 and S. enigma Yakovlev, 2007) live on Turkey and Transcaucasia, and two species (S. kamelini Yakovlev, 2004 and S. tarbagataica Yakovlev, 2014) penetrate deeply into the north-east of the genus range and are endemics of the mountains of south (Kazakhstan) Altai and Tarbagatay in East Kazakhstan.

One of the morphologically well isolated species is the highland S. monticola (Groum-Grshimaïlo, 1890). Endagria monticola was described from “Elle a été prise sur les pentes méridionales des monts Alaï, sur le col Djirgué-talbil (10,500 à 11,000 p. [3200−3350 m]), à la mi-Juillet, la nuit, à la lueur d’une lampe, et pendant une averse” in the remarkable monograph on the Lepidoptera fauna of Pamir, published in French and providing wonderful informative illustrations (Groum-Grshimaïlo 1890: 544−445, Pl. XX: Fig. 5) (Fig. 1). Examining the specimens, externally similar to S. monticola, we have found four new species. Their description is given below.

Material and methods

Male genitalia were mounted in euparal on slides following Lafontaine and Mikkola (1987). The imagoes were photographed using digital camera of iPhone 7. The genitalia preparations were photographed using an Olympus DP74 camera attached to an Olympus SZX16 stereomicroscope. The morphological terminology used in the description follows Kristensen (2003). The images were processed using Corel Photo-Paint 2017 software. The distribution map was generated using SimpleMappr software (Shorthouse 2010).

The material is deposited in the Museum Witt, Munich (MWM), Zoological Institute, St. Petersburg (ZISP); Naturhistorisches Museum, Wien (MNHW), and private collection of first author, Barnaul (RYB).

Description. Fore wing in length 16 mm in holotype, 11−16 mm in paratypes. Antenna about 1/3 of fore wing in length, bipectinate, setae very short, not longer than antenna stem in diameter. Fore wing light-grey, with thin white border on costal edge (with small grey dots), brown strokes throughout all wing (more expressed from base to postdiscal portion), small white spot at top of discal cell, thin oblique dark-brown band in postdiscal portion cubitally, tiny hardly noticeable brown strokes submarginally and marginally, border thin, brown, fringe mottled (dark at veins, light between veins). Hind wing light-grey without pattern, border thin, brown, fringe mottled (dark at veins, light between veins).

Male genitalia. Uncus robust, tapered, basally wide, slightly narrowing to apex, apically slightly acute, strongly sclerotized; gnathos arms thin, short; gnathos of medium thickness, roll-like; valve poorly narrowing from base to apex, distal (apical) portion of valve membranous, costal edge of valve with semicircular, strongly sclerotized crest of medium size (crest edge with small folds), apex of valve lanceolate; transtilla process thick, short, poorly curved in medium third, apically sharp; juxta tiny, saddle-like, with short lobe-like lateral processes diverged at blunt angle; saccus small, semicircular; phallus shorter than valve (about 3/4 of valve in length), slightly curved in medium third, slightly narrowing from base to apex, vesica aperture in dorso-lateral direction, about 1/2 of phallus in length, vesica without cornuti.

Female unknown.

Diagnosis. The new species differs from the close S. monticola in a series of characters:

• the distinct thin oblique dark-brown band in the postdiscal portion cubitally;

• the thinner gnathos;

• the relatively poorly expressed crest on the costal edge of the valve;

• the short phallus.

Distribution. Kyrgyzstan (Inner Tian-Shan).

Etymology. The new species is named after our friend and colleague Sergei Churkin (Reutov), a well-known specialist in systematics and zoogeography of Papilionoidea in the Palaearctic, who made a significant contribution into the study of the Inner Tian-Shan fauna.

Female unknown.

Diagnosis. The new species differs from the close S. monticola in a series of characters:

• the process on the costal edge of the valve is semicircular, with small teeth (in S. monticola, the process on the costal edge of the valve is trapezoidal),

• the transtilla processes are more curved (in S. monticola, the transtilla processes are less curved).

Distribution. Tajikistan (Eastern Pamir Mountains).

Etymology. The new species is named after our friend and colleague, the famous arachnologist Alexander Fomichev (Barnaul), who did a great job studying the spiders of Central Asia, including the Eastern Pamirs.

Female unknown.

Diagnosis. The new species differs from the close S. monticola in a series of characters:

more mottled, fine-spotted coloring of the fore wing,
the thin processes of the transtilla (in S. monticola, the transtilla processes are thicker),
the shorter aperture of the vesica, 2/5 of the phallus in length (in S. monticola, the vesica aperture is 3/5 of phallus in length).

Etymology. The new species is named after the first author's friend, our guide in the Pamirs, Mr. Uvaydo Kudratbekov (Pershinev, Tajikistan), without his help our research into the mountains of Badakhshan would have been impossible.

Discussion

Thus, Semagystia monticola (Groum-Grshimaïlo, 1890) species group includes 9 species, widespread in mountainous areas from Altai to Paropamiz (Fig. 20). The most north-eastern location is the Narym Range in the Kazakh part of the Altai Mountains (S. kamelini), and the south-western one is Logar Valley in the Central Afghanistan (S. witti). The species discussed here are endemic to certain mountain systems of Central Asia. If we consider the distribution of the group from north to south, then the endemic of Altai and Dzungarian Alatau is S. kamelini; of the Inner Tian-Shan – S. churkini; Western Tian-Shan − S. toropovi; Alai and Transalai – S. monticola; Gissar – S. lukhtanovi; Darvaz – S. uvaydo; Eastern Pamir – S. fomichevi; Paropamiz – S. wernerithomasi and S. witti. The specimens of this species group are among the highest altitude representatives of the Cossidae family in Eurasia . In Altai, they are reported from the altitudes up to 2100 m, in Tian-Shan − up to 2400 m, on Alai and Transalai Mts. − up to 3400 m, on the Gissar and Darvaz Mts. − up to 3350 m, on the Eastern Pamir − 3900 m, on the Paropamiz − 3000 m. The flight of adults occurs in the middle of the summer, with the exception of Afghanistan (in April−May), where the phenological summer begins much earlier than in more northern regions. Further molecular genetic research of this group representatives is of great interest; the DNA sequences have already been obtained for most taxa, which will be analyzed in our subsequent works.
