Ground color white (specimens preserved in ethanol before examination), eyes grey, face with indistinct longitudinal brown medial band. Basal triangles of mesonotum brown. Forewing dark brown apically near costal margin. (Figs 24 a–d) Anal tube appendage (Fig. 1e) narrow, base curved, apex blunt, as wide as base.

Aedeagal shaft (Figs 1k, l) narrow and straight; preatrium rudimentary, region between preatrium and dorsal apodeme slightly wider than base of shaft in caudal view; gonopore central. Measurement. Male length 3.00mm. Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.196'S, 015°28.267'E, 23.viii.2008, coll. Braet & Sharkey. Paratypes: 1♂, same data as holotype; 2♂, same data except 25.viii.2008; 1♂, same data except 03°16.020'S, 015°31.440'E, 19–26.viii.2008. Etymology.
