Barsine thagyamin Volynkin & Černý

sp. nov.

Barsine thagyamin Volynkin & Černý   , sp. nov.

( Figs 15, 16 View FIGURES 9–16 , 38, 39 View FIGURES 36–39 )

Type material. Holotype ( Figs 15 View FIGURES 9–16 , 38 View FIGURES 36–39 ): “ Myanmar (Burma), Putao , 500m, 23.V.1998, leg. Murzin & Sinjaev”, slide MWM 33587 View Materials Volynkin (Coll. MWM / ZSM).  

Paratype: 1 ♁, same data as in the holotype, slide MWM 33694 View Materials   Volynkin (Coll. MWM / ZSM).

Diagnosis. Forewing length is 12 mm in males. Externally, B. thagyamin   is very similar to B. hreblayi   , but can be distinguished by its broader and paler yellow stripes on forewing veins and paler hindwing. Compared to B. inflexa   , B. thagyamin   has the pale red hindwing (that is pale ochreous in B. inflexa   ) and narrower blackish edge of forewing costa. The male genitalia of B. thagyamin   resemble those of B. victoria   , but differ clearly by their uncus being shorter and narrower basally; more heavily sclerotized juxta; smaller medial costal process; much larger, trigonal distal costal process directed dorsally (whereas in B. victoria   that is short and directed distally); smaller distal membranous lobe of valva; broader and longer sacculus bearing a small medial process (that is absent in B. victoria   ); longer distal saccular process; larger aedeagus; larger, bilobate subbasal diverticulum without cornuti; smaller dorsal medial diverticulum with a narrower cluster of small cornuti; narrower and more elongated ventral medium diverticulum; and smaller cluster of cornuti at base of the distal diverticulum. The male genitalia of B. thagyamin   can be easily distinguished from those of B. gloriosa   by their longer and basally narrower uncus, much larger distal costal process, much broader distal saccular process, less curved aedeagus, bilobate subbasal diverticulum (that is unilobate in B. gloriosa   ), narrower dorsal medial diverticulum, the presence of a dorsal distal diverticulum (absent in B. gloriosa   ) and more robust cornuti on the ventral medial diverticulum.

Female is unknown.

Distribution. The species is known only from its type locality in Kachin State, North Myanmar.

Etymology. Thagyamin is the highest-ranking nat (spirit worshipped in Myanmar) in traditional Burmese Buddhist belief.
