Amanota congoensis Cameron, 1950: 52 View in CoL .

Type material. Holotype: ♂: Congo Belge [ Democratic Republic of the Congo]: P. N. A. [Parc Nat. Albert], Shamuhuru (volc. Nyamuragira), 1843 m, 15.VI.1935, G. F. de Witte ( MRAC) . Paratypes: ♂: same data as holotype ( BMNH) ; ♂: Congo Belge [ Zaire]: P. N. A. Kitondo (près Gandjo ), 2000 m, 7–23.I.1935, G. F. de Witte ( BMNH) ; ♂: Congo Belge [ Democratic Republic of the Congo]: P. N. A. Kitondo (près Gandjo ), 2000 m, 7– 23.I.1935, G. F. de Witte ( MRAC) ; ♂: Congo Belge [ Democratic Republic of the Congo]: P. N. A. Mushumangabo (volc. Nyamuragira ), 2075 m, 14.VI.1935, G. F. de Witte ( MRAC) .

Redescription. Body. Length 2.6 mm, convex, parallel­sided, glossy; body colour brown; elytra reddish brown, abdominal tergites 7–8 black, legs and antennae pitchy brown, antennomeres 1–2 and 10–11 red.

Head quadrate in outline, moderately convex, broadly and moderately deeply 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 without microsculpture; puncturation coarse and dense. Antennae long, clearly increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–10 longer than wide, decreasing in length, antennomere 11 nearly conical.

Pronotum subquadrate, moderately convex, broadly and 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 transverse, at suture slightly shorter than pronotum at midline; surface without microsculpture; puncturation fine and dense.

Abdomen parallel sided, 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 dense, surface lacking microsculpture.

Male. Aedeagus as in Figs. 84–85 View FIGURES 84–85 .

Female unknown.

Remarks. Ischnopoda congoensis is closely related to I. basalis , from which it can be distinguished by the convex head, not flattened dorsally, the smaller eyes, subequal in length to that of postocular region and by antennomere 10 as long as wide.

Distribution. The species is known only from a few localities in Democratic Republic of the Congo.
