Ischnopodadepressa Pa ś nik, sp. n. ( Figs. 74–75 )

Type material. Holotype: ♂: Cameroon, Mts Bamboutos , 2500 m, 2.V.1965, De Mire ( MNHN) . Paratypes: 2♂♂: same data as the holotype ( MNHN) ; ♂: same data as the holotype ( ISEA) .

Description. Body. Length 3.5–3.6 mm, convex, parallel­sided, glossy; body colour dark brown; head black, abdominal tergites 3–4 brownish red, legs and antennae brown, first antennomere and tarsi red.

Head circular in outline, convex, broadly and deeply impressed medially, narrower than pronotum, widest across eyes; eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; temples arcuately narrowed to hind angles; surface of head with dense isodiametric mesh microsculpture; puncturation relatively coarse and dense; pubescence short and dense, directed inward. Antennae short, clearly increased in width apically, antennomere 3 slightly shorter than 2, antennomeres 4–8 longer than wide, antennomeres 9–10 quadrate, antennomere 11 nearly conical.

Pronotum quadrate, convex, widest in apical third, lateral sides concavely narrowed to obtuse hind angles; before base with moderately small and shallow transverse impression, deeply and broadly impressed medially; surface with isodiametric mesh microsculpture, puncturation fine, dense and asperate; pubescence at midline directed entirely anteriorly.

Elytra transverse, slightly wider than pronotum, at suture slightly shorter than pronotum at midline; surface without microsculpture; puncturation fine, dense and asperate.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, first two impressions coarsely and densely punctuate, third impression much finer

punctuate, tergal puncturation uniformly fine and dense; surface lacking microsculpture. Male. Aedeagus as in Figs. 74–75 .

Female unknown.

Remarks. See under I. burgeoni .

Etymology. The name depressa refers to the head deeply impressed medially.

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