Redescription of the lectotype (♂). Body length 14.9 mm, elongate, almost parallel, strongly convex. Dorsal and ventral surface weakly shiny, head and pronotum dark brown, elytra reddish-brown, macrosetation pale (Fig. 5A). Dorsal surface of head, pronotum, scutellum, and elytra covered with white, short, recumbent, scale-like macrosetae; ventral surface of thorax and abdomen with yellow, recumbent, long macrosetae. Head, appendages, and legs covered with reddish-yellow, moderately long macrosetae.
Head with labrum transverse, deeply bilobed; lobes rounded, irregularly and weakly punctate; lobes covered with long, erect macrosetae. Head including clypeus smooth, matte, densely coarsely punctate; each puncture with a macroseta shorter than puncture diameter. Frontoclypeal carina sinuate in the forward direction but medially straight, frons behind the carina randomly punctate, punctures as on clypeus. Frontoclypeal suture undulate, at middle doubly arched toward occipital carina. Occipital carina always present, prominent, elevated; medially extended into a thin (in dorsal view razor-sharp), broad, impunctate double summit, laterally diminishing (Fig. 5B). Surface behind frontoclypeal suture impunctate. Occiput with a mix of sparse and moderate punctate. Canthus narrow, short, glabrous. Width of both eyes combined approximately equal to maximum width of frons between eyes, eye distinctly extending beyond canthus. Antenna with 10 antennomeres; club with three antennomeres, almost straight, as long as antennal shaft (antennomeres 1–7 combined). Antennomeres 1–7 with sparse, long macrosetae; club sparsely, shortly macrosetaceous. Terminal maxillary palpomere expanded apically, approximately shorter as palpomeres 2 and 3 combined.
Pronotum transverse, widest behind midlength; with a round, anteromedial shallow depression gradually rising toward edge of crest. Front margin straight, with angles extended forward. Lateral margins crenulate and macrosetose. Base bordered, medially gently arched toward elytra, with smooth margin paralleled by a row of coarse punctures and hind angles broadly rounded. Crest delimiting anteromedial depression prominent, with edge impunctate. Pronotal punctation asperate and macrosetose, anteriorly denser than toward base; setae no longer than half of puncture diameters, yellow, scale-like, semirecumbent (Fig. 5C).
Scutellum large, almost equilaterally triangular; sides and apex rounded; sides punctate, each bearing short narrow, white, scale-like, almost recumbent macroseta.
Elytra weakly convex, parallel-sided, rounded apically; apical angle approximately rectangular. Striae absent, excepting feebly visible sutural stria. Humeral umbones present, weakly swollen. Surface not microsculptured, moderately shiny, with shallow and regularly spaced punctures separated by their diameter. Each puncture bearing narrow, yellow, scale-like, almost recumbent macroseta; setae as long as or slightly shorter than the puncture diameter. Epipleuron distinct, complete, narrow, glabrous laterally. Macropterous.
Legs with femora narrow, shiny, irregularly punctate; macrosetaceous. Protibia narrow, distinctly tridentate; terminal spine inserted against medial dent. Mesotibia and metatibia slightly expanded apicad, with one macrosetiferous longitudinal carinae. Upper terminal spine of metatibia flattened, slightly curved, acute apically; 1/ 3 longer than lower, apically trunctate, chisel-shaped metatibial spine. Claws bifid, with ventrobasal teeth (Fig. 9E).
Ventral surface covered only by long, semierect, yellow macrosetae. Pygidium slightly transverse, convex, completely bordered; apically broadly rounded; irregularly covered by coarse umbilicate, macrosetiferous punctures.
Male genitalia (Figs. 7E, 8E). Parameres symmetrical, longer than phallobasis, regularly curved in lateral aspect, rounded apically in lateral aspect, with somewhat pincers-like apex; covered by short, fine, semierect, yellow macrosetae.
Sexual dimorphism. Female unknown.
Geographic distribution. Democratic Republic of the Congo, Bas-Fleuve Region (Fig. 10E).
Remark. This species was described based on two males. A lectotype is designated here to enhance stability of nomenclature (International Commission on Zoological Nomenclature 1999, Article 74). The location of the paralectotypes is unknown.
