Sunius dearmatus View in CoL spec. nov.

( Figs 19–22 View Figs 15–26 )

Type material: Holotype ♂: “E. NEPAL: KOSI, Chichila s/Ahale , 2200 m, 24.IV.84, Löbl-Smetana / Holotypus ♂ Sunius dearmatus spec. nov. det. V. Assing 2015” ( MHNG) . Paratype ♂ [forebody missing]: same data as holotype (cAss) .

Etymology: The specific epithet is the past participle of the Latin verb dearmare (to disarm) and alludes to the absence of long sclerotized structures in the internal sac of the aedeagus.

Description: Body length 3.4 mm; length of forebody 1.7 mm. Eyes approximately twice as long as postocular region in dorsal view ( Fig. 19 View Figs 15–26 ). Other external characters similar to those of S. marratus .

♂: sternite VII without distinct modifications; sternite VIII ( Fig. 20 View Figs 15–26 ) weakly oblong, posterior excision small and shallow, less than one-tenth as deep as the length of sternite; aedeagus ( Figs 21–22 View Figs 15–26 ) of distinctive morphology, approximately 0.5 mm long; ventral process of distinctive shape; internal sac only with short and moderately sclerotized structures.

Comparative notes: Based on the external and male sexual characters, S. dearmatus belongs to the S. manasluensis group. It differs from other species of this group by the shape of the male sternite VIII and particularly by the morphology of the aedeagus.

Distribution and natural history: The type locality is situated in Kosi province, East Nepal, at an altitude of 2200 m.
