Afromicracis jasminiae (Schedl, 1957)

( Figs 12, 15, 18 )

Dendrochilus jasminiae Schedl, 1957 (original spelling)

Type material. Holotype, sex? Congo, Kivu, Mt. Kahuzi [GIS: -2.30, 28.71], 2240 m ( RMCA) . Paratype (1): Congo, Yangambi ( NHMW) .

Diagnosis, sex? Length 1.7 mm, 2.6 × as long as wide. Frons smooth, slightly concave near epistoma, setae scant; antennal scapus with few dorsal setae; antennal club as long as broad, one procurved suture strongly marked on apical third; eyes separated above by 2.5 × their width. Pronotal asperities close but not contiguous, setae on anterior half hair- or bristle-like, on posterior half spatulate. Elytra with uniseriate rows of spatulate setae on each interstriae, some setae truncated, on declivity closer than on disc, separated by their length or slightly more; strial setae barely visible. Protibiae narrow, with one lateral and three apical denticles.

Remarks. Examination of the entire type series revealed sufficient differences between this species and the next, A. mikaniae . In A. jasminae the interstrial setae are broader and partly truncated (vs bristle-like), separated by 2–3 × their length (vs. separated by less than their length) and located in uniseriate rows throughout (vs confused on lower declivity). A paratype of this species at NHMW are likely not the same species, having a more gently sloping declivity and was from the Congo basin (Yangambi).
