Abstract The article describes a new species, Patoptoformis poltavskyi, sp. nov. (Lepidoptera, Cossidae: Cossinae) from Northern Laos. We give the images of the adults and genital structures for all the species of the genus. The distribution map of the genus Patoptoformis Yakovlev, 2006 is provided.

Key words: Biodiversity, carpenter-moths, Oriental Region, taxonomy, entomology.

Introduction

The genus Patoptoformis was established for Patoptoformis hanuman Yakovlev, 2006 from Assam (NE India) (Yakovlev 2006). In the same publication, the previously described (Yakovlev 2004) from N. Nepal Patopta (sic!) ganesha Yakovlev, 2004 was recombined to the genus Patoptoformis. Later, Patoptoformis rimsaitae Saldaitis & Yakovlev, 2012 was described from Central Sichuan (China) (Ivinskis et al. 2012). The genus is characterized by the following features. Moths small, dark. Antenna bipectinate in males, filiform in females. Fore wing with poorly expressed undulated pattern of dark transverse lines. Hind wing without pattern. Fringe dark on all wings. Male genitalia. Uncus long, triangle, apically sharp. Gnathos arms long, gnathos of medium size, covered with fine spikes. Valves with costal crest, its distal edge abruptly passes into membranous part. Transtilla processes basally thick, of medium length, hooked. Juxta tiny. Saccus semicircular, very small. Aedeagus short, thick, apex obliquely cut, distal aperture in dorso-apical position, about half of aedeagus in length. Female genitalia. Ovipositor long, papillae anales elongated, cylindrical, apically rounded. Apophyses very long. Posterior apophyses two times longer than anterior. Ostium immersed, heart-shaped. Ductus thin, long, bursa copulatrix bag-like, elongated. Ductus seminalis thin, flowing into base of bursa copulatrix. Examining the materials stored in the Museum Witt, Munich, Germany (later − MWM) we found a new species of this rare genus collected in northern Laos.

NEW SPECIES OF PATOPTOFORMIS YAKOVLEV, 2006 FROM NORTHERN LAOS

Material and methods

Adults of Cossidae were collected using light traps. Male and female genitalia were mounted in euparal on slides following Lafontaine and Mikkola (Lafontaine & Mikkola 1987). The adults were photographed using different digital cameras. The genitalia preparations were photographed using a Olympus DP74 camera attached to an Olympus SZX16 stereomicroscope.

Description of new species

Patoptoformis poltavskyi Yakovlev, sp. nov. Figs 1, 5, 9

Material examined. Holotype, male, Laos NW, 5 km E Muang Sing, Chiang Tung (Stupa) GH, 750 m, 26.iii.−05.iv.2010, leg. local coll. (MWM).

Description. Antenna bipectinate, crest processes 2.5 times longer than antenna rod diameter. Length of fore wing 10 mm. Fore wing relatively short, apically rounded, dark-brown, with poorly expressed dark pattern in root area and narrow black bands discally, postdiscally and submarginally, fringe dark-brown. Hind wing black, without pattern, fringe black. Male genitalia (GenPr Heterocera MWM N 25.261). Uncus long, apically semicircular; gnathos arms long, thin; gnathos robust, covered with fine spikes; valve basally wide, narrow in medium third, slightly widening to apex, membranous edge of valve obliquely connected with sclerotized part on abdominal edge, poorly expressed crest on costal edge; transtilla process strongly sclerotized, hooked, gradually narrowing from base to apex; juxta saddle-shaped with deep semicircular cut in medium part and two long thin lateral processes; saccus semicircular; aedeagus thick, strongly curved in medium third, apex sharp, obliquely cut, vesical aperture about 2/3 of aedeagus in length, vesical without cornuti.

Diagnosis. The new species clearly differs from all the known species of the genus: - from P. ganesha – externally: the new species is significantly smaller, in P. Ganesha the thin transverse bands on the fore wing are more expressed; - from P. hanuman and P. rimsaitae – in the male genital structure (in the new species, the membranous edge of the valve is very blunt and short; in P. Hanuman, the saccus is significantly smaller, in P. rimsaitae – the juxta lateral processes are more robust).

Etymology. The new species is named after my dear colleague and co-author, Dr. Alexandr N. Poltavsky (Rostov-na-Donu, Russia) (1954−2020) well-known entomologist, specialist in Lepidoptera on the Caucasus, who untimely left us during the pandemic.
