Ischnopodaspissata Pa ś nik, sp. n. ( Figs. 97–98 )

Type material. Holotype: ♂: Ethiopia: Kaffa , 16 km N of Jimma, 2100 m, X.1971, under heaps of muddy sticks and twigs ( BMNH).

Description. Body. Length 2.3 mm, convex, parallel­sided, glossy; body colour brown; legs yellow, antennae brown with first antennomere red.

Head quadrate in outline, moderately convex; 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 coarse and dense. Antennae long, increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–7 longer than wide, antennomeres 8–10 as long as wide, antennomere 11 nearly conical.

Pronotum subquadrate, moderately convex, broadly and moderately deeply impressed medially, lateral sides concavely narrowed to obtuse hind angles; before base with small transverse impression; surface without microsculpture, puncturation coarse and dense; pubescence at midline directed posteriorly in apical half and anteriorly in basal half.

Elytra subquadrate, at suture as long as pronotum at midline; surface without microsculpture; puncturation fine and moderately dense, much finer than that on pronotum.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, impressions coarsely and densely punctuate, tergal puncturation fine and moderately dense, surface lacking microsculpture.

Male. Aedeagus as in Figs. 97–98 .

Female unknown.

Remarks. Ischnopoda spissata is closely related to I. capensis and I. basilewskyi , but can be distinguished from both by its smaller body size, the abdomen uniformly brown, antennomere 10 as long as wide and particularly by the shape of the aedeagus.

Etymology. The name spissata refers to the very dense head and pronotal puncturation.

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