Type material. Holotype, sex? Ghana, Kumasi [GIS: 6.68, -1.57], 26.x.1961, F.G. Browne, leg. Paratype (1): Same data as HT, except 2.xi.1961 . Holotype in NHMW, paratype in NHMUK.

Diagnosis. Pronotal asperities small and sharp, separated by their size; strial setae as long as distance between them, or slightly longer; ventral setae not longer than interstrial setae.

Description female. Length 1.4–1.5 mm, 2.6 × as long as wide. Colour brown. Frons broadly, lightly impressed, smooth and shiny with short, fine, erect setae; a pair of narrowly separated, tiny tubercles near upper level of eyes; scapus with scant setae; club with a fine procurved suture near apical margin. Eyes separated above by 1.5–1.7 × their width. Pronotum with small sharp asperities on anterior half, each tubercle separated by their size, posterior half smooth and shiny; vestiture consisting of mixed hair-like and spatulate setae. Elytral striae not impressed, interstriae weakly rugose. Vestiture consisting of long recumbent strial setae, length of each as long as or longer than their separation, and densely placed spatulate or truncated broad setae in rows on each interstria. Legs. Protibiae with one lateral and two apical denticles. Ventrites. Vestiture of short, scattered setae, about as long as interstrial setae.
