Typhlotectusa frischi nov.sp. ( Figs 1-10 ) T y p e m a t e r i a l: Holotype ♂: " Kyrgyzstan: Issyk-Kul , Kyzyl-Tuu - Kyzyl-Suu: S Barskoon, Barskaun Pass, 3770 m, N41°53'30'' E077°41'59'', 24.06.2011, leg. J. Frisch / Holotypus ♂ Typhlotectusa frischi sp. n., det. V. Assing 2019" (cAss).

E t y m o l o g y: This remarkable species is dedicated to Johannes Frisch, who collected the holotype.

D e s c r i p t i o n: Body length 2.5 mm; length of forebody 1.05 mm. Habitus as in Fig. 1 . Coloration: body yellowish-red with dark-yellow legs and antennae.

Head ( Figs 2-3 ) weakly oblong; punctation very fine and rather dense, barely visible in the pronounced microreticulation. Eyes completely reduced, not even rudiments visible ( Fig. 3 ). Antenna 0.6 mm long; antennomere III of conical shape and weakly oblong; antennomeres IV-X strongly transverse, more than twice as broad as long, and of gradually increasing width, XI slightly longer than the combined length of IX and X.

Pronotum ( Fig. 2 ) very weakly transverse, only 1.05 times as brad as long and 1.05 times as broad as head, with weakly marked posterior angles; punctation dense and extremely fine, nearly invisible in the pronounced microreticulation even at high magnification.

Elytra ( Fig. 2 ) short and slender, as broad as, and 0.7 times as long as pronotum; punctation dense and fine, but more distinct than that of head and pronotum; interstices with shallow microsculpture and glossy. Hind wings completely reduced.

Abdomen 1.1 times as broad as elytra at segment VI; punctation fine and moderately dense; interstices with microsculpture; posterior margin of tergite VII without palisade fringe; posterior margin of tergite VIII truncate ( Fig. 5 ).

♂: sternite VIII ( Fig. 6 ) approximately as long as broad, with weakly convex posterior margin; median lobe of aedeagus 0.27 mm long and shaped as in Figs 8-9 ; paramere ( Fig. 10 ) 0.36 mm long.

♀: unknown.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The type locality is situated in East Kyrgyzstan to the south of Issyk-Kul lake. The holotype was collected at an altitude of nearly 3800 m.
