Entypopana Lujai Moser, 1917: 255 (description); Burgeon 1946: 263 (comparison of E. hulstaerti and E. maynei)
Type locality. “ Congo belge (Kondué) [= Democratic Republic of Congo, Kasai Oriental Region, near Lusambo]”. Type material. Lectotype (by present designation), ♂, labelled: “Ed. LUJA / KONDUÉ / CONGO - BELGE [white, printed] // Entypophana / Lujai Mos. / Type ♂ [white, handwritten]”.
Type depository. ZMHUB.
Additional material exanimed (1 specimen). DEMOCRATIC REPUBLIC OF THE CONGO: Stanleyville [= Kisangani], Congo, 1 ♀ in IRSNB.
Redescription of lectotype (♂). Body length 19.3 mm, elongate, almost parallel-sided, strongly convex. Dorsal and ventral surfaces weakly shiny, elytra reddish brown, macrosetation pale (Fig. 4A). Dorsal surface of head, pronotum, scutellum, and elytra covered with short, recumbent, scale-like, white macrosetae; ventral surface of thorax and abdomen with long, recumbent, yellow macrosetae. Head appendages and legs covered with moderately long, reddish-yellow macrosetae.
Head with labrum transverse, deeply bilobed; lobes rounded, unevenly weakly punctate; lobes covered with long, erect macrosetae. Head including clypeus smooth, glossy, fissured, densely coarsely punctate; each puncture with an erect macroseta as long as puncture diameter. Frontoclypeal carina elevated, medially sinuate forward, base as punctate as clypeus; setae semierect at varied angles, at least twice as long as puncture diameters. Frontoclypeal suture slightly undulate, medially arched toward occipital carina. Occipital carina always present, prominent, elevated; medially with a flat, broad, glossy, impunctate double summit, laterally diminishing (Fig. 4B). Space posterior of frontoclypeal suture with a small, triangular facet devoid of punctures and setae. Occiput sparsely regularly, moderately punctate. Canthus narrow, short, bare. 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 2–7 combined). Antennomeres 1–7 with sparse, long macrosetae; club sparsely, shortly macrosetaceous. Terminal maxillary broken.
Pronotum transverse, widest behind midlength; with anteromedial, semioval depression narrower and flat in anterior third, then gradually widening and reclining toward 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 frontal and top edges impunctate, between edge of crest and base punctate as sparsely as in anterior part of pronotum. Flat part of depression densely punctate, punctures spherical, setae twice as long as puncture diameters. Remaining parts with macrosetose punctation; setae yellow, scale-like, semierect (Fig. 4C).
Scutellum large, almost equilaterally triangular, sides and apex rounded; disc punctate as elytra.
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; punctation coarse, almost regularly spaced; punctures separated by their diameter. Each puncture bearing a seta as long as or slightly longer 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. 9D).
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. 7D, 8D). Parameres symmetrical, longer than phallobasis, regularly curved in lateral aspect, rounded apically in lateral aspect; covered by short, fine, semierect, yellow macrosetae.
Sexual dimorphism. Female differs from male in the following characters: body shorter (16.0 mm), considerably shorter; anteromedial depression weak.
Geographic distribution. Democratic Republic of Congo, Kasai Oriental Region (Fig. 10D).
Remark. This species was described based on an unstated number of specimens of both sexes. A lectotype is designated here to enhance stability of nomenclature (International Commission on Zoological Nomenclature 1999, Article 74).
