Redescription.

Habitus as in Fig. 49. Body length = 12.0-14.0 mm. Elytra wider and longer than pronotum (width ratio elytra / pronotum = 1.1-1.2; length ratio elytra / the middle of pronotum = 2.4-2.6).

Dorsal side of head dull, with punctures (the intervals between the punctures are smaller than the diameter of the puncture). Frontoclypeal suture coarse. Clypeal emargination relatively deep (clypeal emargination width / depth ratio = 8.0-8.4). Mentum with median part narrow. Submentum with short base. Maxillary palp not widened (width of maxillary palp / length of 3rd antennomere = 1.0-1.1). Length of antennae greater than pronotal length (ratio antenna / pronotum from tip of anterior pronotal angle to tip of posterior pronotal angle = 1.2-1.3). 3rd antennomere relatively long (length ratio of antennomere 3rd / 2nd = 2.7-3.0).

Pronotal disc transverse (middle of pronotum length / width ratio = 0.4-0.5); dull, with coarse punctures (the intervals between the punctures are smaller than the diameter of the puncture). Anterior pronotal angles sharp and protruding outwards. Lateral margins of pronotum sinusoidal. Apophyseal and basal depressions on pronotal disc present; apophyseal depressions rounded. Pronotal hypomera dull; without punctures.

Elytra oblong (elytra length / width ratio = 1.1-1.2). Elytral striae with fine punctures; intervals non-convex, with transverse sculpture. Elytral base slightly rounded. Elytral humeri rounded, not protruding laterad. Wings absent. Scutellum triangular; situated in a depression.

Intercoxal process not protruding towards mesoventrite, rounded at the apex. Metaventrite reduced (length ratio cavity of hind coxa / metaventrite between the insertions of mid and hind coxae ca. 2). In both sexes abdominal process without tubercles; relatively narrow (process of 1st abdominal ventrite / process of metaventrite ca. 2.0. 5th abdominal ventrite without bordering; punctures fine (the intervals between the punctures are greater than the 2 diameters of the puncture).

Male legs. Protarsi slightly narrow. Protibiae as in Fig. 32. Mesotibiae and mesofemorae with large denticle. Metafemorae with an hair fringe. Female legs simple.

Male genitalia. Parameres narrowest in the half of their length; length equal to 0.2 of the rest of aedeagal tegmen. Clavae hook-shaped. Female genitalia. Paraproct equal to coxites. Bursa copulatrix with a sclerite in distal part. Spermatheca with narrow ducts.

Distribution.

This species has been collected in the following ecoregions of Central Africa (Angola, Democratic Republic of the Congo, Republic of Rwanda, Republic of the Congo): Albertine Rift montane forests, Angolan Miombo woodlands, Atlantic Equatorial coastal forests, Western Congolian forest-savanna mosaic (Fig. 41).
