Ischnopoderona albicornis ( Tottenham, 1957) , comb. n.

( Fig. 21 , Map 1)

Amanota albicornis Tottenham, 1957: 123 .

Type material. Holotype: Ψ: Urundi [ Burundi]: Bururi, Nyamurembe, 900 m, 7.III.1953, P. Basilewsky ( MRAC).

Redescription. Body. Length 3.2 mm, convex, parallel­sided, glossy; body colour brown; tergites III–V reddish­brown, antennae black with antennomeres 1–3 reddish­yellow and antennomeres 10–11 white, legs brown with tibiae and tarsi yellow.

Head circular 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 minute, pinprick­like and moderately sparse. Antennae very long, extending to 3/4 of elytra, slightly increasing in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–10 longer than wide, decreasing in length, antennomere 11 nearly coniform.

Pronotum quadrate, convex, lateral sides sinuately narrowed to obtuse hind angles; before base with small and shallow transverse impression; surface lacking microsculpture; puncturation in posterior half moderately fine and dense, in anterior half very fine and moderately sparse; pubescence at midline directed posteriorly in apical 1/4 and anteriorly in basal 3/4.

Elytra subquadrate, at suture slightly shorter than pronotal length at midline; surface without microsculpture; puncturation minute, pinprick­like and scattered.

Abdomen widened posteriorly, bases of tergites III–V each with deep transverse impression, first impression coarsely and densely punctate, second and third impressions smooth, impunctate; tergal puncturation fine and moderately dense; surface without microsculpture.

Male unknown.

Female. Spermatheca as in Fig. 21 .

Remarks. Ischnopoderona albicornis is very similar to I. transvaalica , from which it can be distinguished by its larger size, the antennomere 11 white (red in I. transvaalica ), the tergites III and IV red (tergites III and IV brown in I. transvaalica ) and by the shape of the spermatheca.

Distribution. Burundi (Map 1).

Male. Aedeagus as in Figs. 22–23 .

Remarks. See remarks under I. albicornis .

Etymology. The name transvaalica refers to the type locality.

Type material. Holotype: ɗ: Gabon, Makokou, 27.I.1963, H. Coiffait ( MNHN); Paratypes: 2ΨΨ: same data as holotype, except: 16.I.1963, H. Coiffait ( MNHN); 2ɗ ɗ, 2ΨΨ: Gabon, Belinga, 20.I.1963, H. Coiffait ( ISEA); ɗ: Democratic Republic of the Congo, Kolwezi, H. Katanga, 6.VIII.1953, V. Allard ( MNHN).

Description. Body. Length 2.4–2.8 mm, convex, parallel­sided, glossy; body colour brown; pronotum reddish­brown, abdomen black with tergites III–IV red, antennae brown with antennomeres 1–2 yellow and 10–11 yellowish­white, legs brown with yellow tarsi.

Head circular in outline, convex; eyes relatively 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 minute, pinprick­like and moderately dense. Antennae very long, extending to 3/4 of elytra, slightly increasing in width apically, antennomere 3 longer than 2, antennomeres 4–10 longer than wide, decreasing in length, antennomere 11 nearly coniform.

Pronotum quadrate, convex, lateral sides sinuately narrowed to obtuse hind angles; before base with small and shallow transverse impression; surface without microsculpture; puncturation in basal 2/3 fine and dense, in anterior 1/3 finer and sparser; pubescence at midline directed posteriorly in apical 1/4 and anteriorly in basal 3/4.

Elytra subquadrate, at suture shorter than pronotal length at midline; surface without microsculpture; puncturation minute, pinprick­like and dense.

Abdomen widened posteriorly, bases of tergites III–V each with deep transverse impression, first impression coarsely punctate, second and third impressions smooth, impunctate; tergal puncturation minute, pinprick­like and moderately dense; surface without microsculpture.

Male. Aedeagus as in Figs. 25–26 .

Female. Spermatheca as in Fig. 27 .

Remarks. Ischnopoderona micans is very similar to I. kaszabi , from which it can be distinguished by the antennomere 3 longer than antennomere 2 (antennomeres 2 and 3 subequal in length in I. kaszabi ), the elytral and tergal puncturation dense (sparse in I. kaszabi ) and by the shape of the aedeagus.

Etymology. The name micans refers to the shining body.

Distribution. Gabon, Congo (Map 1).
