Ischnopodaboliviana Pa ś nik, sp. n. ( Figs. 61–63 )

Type material. Holotype: ♂: Bolivia, Yuracaris ( IRSNB) . Paratypes: ♂ and ♀: same data as the holotype ( IRSNB) .

Description. Body. Length 2.9–3.2 mm, convex, parallel­sided, glossy; body colour dark brown; elytra and legs brownish red, antennae brown with antennomeres 1–3 red.

Head circular in outline, convex, narrowly and moderately deeply impressed medially; widest across eyes; eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; surface of head without microsculpture; puncturation moderately fine and dense; pubescence short and dense, directed inward. Antennae short, clearly increased in width apically, antennomere 3 shorter than 2, antennomeres 4–8 longer than wide, antennomeres 9–10 quadrate, antennomere 11 nearly conical.

Pronotum slightly transverse, moderately convex, widest in apical third, lateral sides rounded in front, gradually narrowed in straight line to obtuse hind angles; before base with moderately small and shallow transverse impression, narrowly and relatively deeply impressed medially; surface without microsculpture; puncturation very fine, pinprick­like, dense and not asperate; pubescence at midline directed entirely anteriorly.

Elytra subquadrate, wider than pronotum, at suture as long as pronotum at midline; surface without microsculpture; puncturation fine, dense and slightly asperate.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, impressions coarsely and densely punctuate, tergal puncturation fine and moderately dense; pubescence short, dense and recumbent.

Male. Aedeagus as in Figs. 61–62 .

Female. Spermatheca as in Fig. 63 .

Remarks. Ischnopoda boliviana is very similar to I. drugmandi , from which it differs by its larger size, the pronotal surface distinctly impressed medially, antennomere 10 as long as wide and by the shape of the genitalia.

Distribution. The species is known only from the type locality in Bolivia.
