Ischnopodapseudobasalis Pa ś nik, sp. n. ( Figs. 89–90 )

Type material. Holotype: ♂: Uganda: Ruwenzori Range , Namwamba Valley, 10100 ft., XII.1934 – I.1935, T. H. E. Jackson ( BMNH).

Description. Body. Length 2.3 mm, convex, parallel­sided, glossy; body colour brown; pronotum brownish red, abdominal tergites 3–4 yellowish–brown, legs red, antennae red.

Head quadrate in outline, flattened dorsally; eyes large, moderately protruding from lateral contours of head, length of each seen from above slightly longer than postocular region; surface of head without microsculpture; puncturation relatively coarse and dense. Antennae long, increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–10 as long as wide, antennomere 11 nearly conical.

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

Elytra transverse, at suture slightly 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 punctuate, third impressions smooth, impunctuate; tergal puncturation fine and moderately dense, surface lacking microsculpture.

Male. Aedeagus as in Figs. 89–90 .

Female unknown.

Remarks. Ischnopoda pseudobasalis is closely related to I. basalis , from which it can be distinguished by its smaller size, the elytral puncturation much finer, the antennae uniformly red, the antennomeres 2 and 3 subequal in length and particularly by the shape of the aedeagus.

Etymology. The name refers to the habitus similar to I. basalis .

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