Ischnopodarugosa Pa ś nik, sp. n. ( Figs. 81–83 )

Type material. Holotype: ♂: Ethiopia: Gemu G., Arba Mireli, 1971, G. de Rougemont ( BMNH) . Paratype: ♀: Ethiopia: Bale , Sof Omar, 1200 m, XII.1971, under damp vegetation ( BMNH) .

Description. Body. Length 2.6 mm, convex, parallel­sided, weakly glossy; body colour brown; elytra brownish red, abdomen black with tergites 3–4 red, legs red, antennae brown with antennomeres 1–2 and 10–11 yellow.

Head quadrate in outline, moderately convex, broadly and shallowly impressed medially; eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; surface of head with fine isodiametric mesh microsculpture; puncturation coarse and dense. Antennae short, clearly increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–10 longer than wide, antennomere 11 nearly conical.

Pronotum subquadrate, moderately convex, lateral sides concavely narrowed to obtuse hind angles; before base with small transverse impression; surface with strong isodiametric mesh microsculpture, puncturation fine and dense; pubescence at midline directed posteriorly in apical half and anteriorly in basal half.

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

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

Male. Aedeagus as in Figs. 81–82 .

Female. Spermatheca as in Fig. 83 .

Remarks. Ischnopoda rugosa is closely related to I. nebulosa , from which it can be distinguished by the head distinctly impressed medially, the smaller eyes, subequal in length to that of postocular region, the elytra with distinct granulose microsculpture and by antennomere 10 longer than wide.

Etymology. The name rugosa refers to the pronotal sculpture.

Distribution. The new species is known only from Ethiopia.
