Additional material. Ethiopia: Iludabor by Didessa River , 1500 m, X.1972, R. Clark, 1 ex ( BMNH) ; 1 ex ( ISEA). Kenya: Kakamega Rain Forest Reserve, ca. 1450 m, Udos Camp site, 12.II.1999, J. Deckert, 1 ex ( ISEA) ; 4 exx ( ZMHB).

Redescription. Body. Length 2.9–3.1 mm, convex, parallel­sided, glossy; body colour black; abdominal tergites 3–4 brown, legs black, antennae black with antennomeres 1–2 and 9–11 yellowish red.

Head transverse, flattened dorsally, broadly and moderately deeply impressed medially; eyes large, moderately protruding from lateral contours of head, length of each seen from above longer than postocular region; surface of head without microsculpture; puncturation relatively coarse and dense. Antennae long, weakly increased in width apically, antennomere 3 longer than 2, antennomeres 4–8 longer than wide, antennomeres 9–10 as long as wide, antennomere 11 nearly conical.

Pronotum subquadrate, moderately convex, moderately broadly and moderately deeply impressed medially, lateral sides concavely narrowed to obtuse hind angles; before base with small transverse impression; surface lacking microsculpture, puncturation coarse 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 coarse 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. 86–87 .

Female. Spermatheca as in Fig. 88 .

Taxonomic notes. My examination of the types listed above, particularly their genitalia, revealed that Amanota bimarginata is conspecific with Myrmecopora basalis . Therefore, Amanota bimarginata Pace is here synonymized with Myrmecopora basalis Cameron , the oldest name available.

Remarks. See under I. congoensis and I. pseudobasalis .

Distribution. Ischnopoda basalis is known from Burundi, Ethiopia, Kenya and Democratic Republic of the Congo.
