Lithosarctia kozlovi Dubatolov, 2002

( Figs. 9 , 30 )

Lithosarctia kozlovi Dubatolov, 2002 , Atalanta 33 (1/2): 175, pl. 7, Figs. 2, 6 (Type locality: “ China, Sichuan, river Yalong Jiang left side, 80 km NW from Garzê, stand “ Chikok ”, 4000 m ”).

Type material examined. Photographs of the holotype ( Figs. 9 , 30 ): ♀, “ 23.IV.1901, China, Sichuan, river Yalong Jiang left side, 80 km NW from Garzê [Ganzi], stand Chikok, 4000 m, P.K. Kozlov [leg.]” (in Russian) / “ 23 April 1901, stand Chikok, basin of Golubaya, 12.000’. Kozl.” (in Russian) / “ Ocnogynodes n. subg., N.J. Kusnezov det.” / “ Ocnogynodes ♀, y-albula (Obth.). det. V. Dubatolov 1985” / “Holotypus Lithosarctia kozlovi Dubatolov, 2002 ” (Coll. ZISP).

Note. The species is known only by the female holotype in rather poor condition. Here we place L. kozlovi into the L. hoeneyi species-group due to the closer similarity of its female genitalia to those of L. witti sp. nov. and not L. y -albulum, but until a discovery of males of this species, the placement of L. kozlovi remains unclear, as well as its taxonomic status because it may represent a subspecies of L. goergneri , which female is still unknown that makes a correct comparison of these two taxa impossible.

Diagnosis. Forewing length is 9 mm in females. L. kozlovi is most probably a close relative of L. witti sp. nov., from which differs in its smaller size, the paler brown wing coloration, the narrower and shorter costal stroke, and the slightly broader and paler longitudinal stroke along the vein 1A; externally it is also similar to L. goergneri , but differs in its smaller size and the broader light pattern elements of both wings. The female genitalia of L. kozlovi differ from those of L. witti sp. nov. in the antevaginal plate narrower, more weakly sclerotized and with smaller lateral lobes, the broader ostium bursae, the slightly narrower ductus bursae with the significantly shorter anterior sclerotized section, the corpus bursae more weakly sclerotized posteriorly and with three signa anteriorly; compared to L. y-albulum, in L. kozlovi the antevaginal plate is with lateral lobes, the pheromone glands are much smaller, and the corpus bursae is more weakly sclerotized posteriorly.

Distribution. The species is known only from its type locality in north-western part of China’s Sichuan Province ( Fig. 40 ).
