Entypophana hulstaerti Burgeon, 1946: 263 (description and comparison with E. lujai ).
Type locality. “ Flandria [= Democratic Republic of the Congo, Equator Region, Flandria , near Ingende village , between confluence of Busira and Momboyo rivers]”.
Type material. Lectotype (by present designation), ♂, labelled: “ TYPUS [printed] / Hulstaerti / Burg [red, handwritten] // MUSÉE DU CONGO / Equater : Flandria [printed] / 1929 [handwritten] / R. P. Hulstaert [white, printed] // Entypophana / Hulstaerti / Type / Burg [white, handwritten]”.
Type depository. MRAC.
Redescription of lectotype (♂). Body length 18.4 mm, elongate, almost parallel-sided, strongly convex. Dorsal and ventral surfaces weakly shiny, elytra reddish brown, macrosetation pale ( Fig. 3A View FIGURES 3 ). 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. Clypeus transverse, anterior margin weakly upturned and shallowly sinuate, anterior angles rounded. Head including clypeus smooth, matte, densely coarsely punctate; each puncture with an erect macroseta one-half longer than puncture diameter. Frontoclypeal carina elevated, medially sinuate forward; base as punctate as clypeus. Frontoclypeal suture straight. Occipital carina always present, prominent; medially with a flat, broad, glossy, impunctate summit, laterally diminishing ( Fig. 3B View FIGURES 3 ). Space posterior of frontoclypeal suture with a small, triangular facet devoid of punctures and setae. Occiput evenly, moderately punctate. Canthus narrow, short, glabrous. Combined width of both eyes approximately equals width of frons between eyes, eye distinctly extending beyond canthus. Antenna with 10 antennomeres; club with three antennomeres, almost straight, distinctly shorter than antennal shaft (antennomeres 1–7 combined). Antennomeres 1–7 with sparse, long macrosetae; club with sparse, short macrosetae. Terminal maxillary palpomere expanded apically, shorter than palpomeres 2 and 3 combined.
Pronotum transverse, widest behind midlength; with anteromedial, oval 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 toward base impunctate except a narrow medial strip at base with punctures as those present laterally. Anterior part of pronotum distinctly punctate, setae from within punctures one-half longer than puncture diameters. Remaining parts similarly punctate but punctures shallow, setae yellow, scale-like, semirecumbent, no longer than puncture diameters ( Fig. 3C View FIGURES 3 ).
Scutellum large, almost equilaterally triangular, sides and apex rounded; sides punctate, each with four large punctures bearing short, narrow, scale-like, semirecumbent, white macroseta.
Elytra weakly convex, parallel-sided, rounded apically; apical angle approximately rectangular. Striae absent except for weakly indicated sutural stria. Humeral umbones present, weakly swollen. Surface not microsculptured, moderately shiny; punctation coarse, almost evenly spaced; punctures separated by 1x their diameter. Each puncture bearing narrow, scale-like, semirecumbent macroseta as long or slightly longer than puncture diameter. Epipleuron distinct, complete, narrow, laterally glabrous. Macropterous.
Legs with femora narrow, shiny, unevenly punctate; macrosetaceous. Protibia narrow, distinctly tridentate; terminal spine inserted over medial tooth. Mesotibiae and metatibiae slightly expanded distally, each with one macrosetiferous, longitudinal carina. 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. 9C View FIGURES 9 ).
Ventral surface covered only by long, semierect, yellow macrosetae. Pygidium slightly transverse, convex, bordered completely; apically broadly rounded; unevenly covered by coarse, umbilicate, macrosetiferous punctures.
Male genitalia ( Figs. 7C View FIGURES 7 , 8C View FIGURES 8 ). Parameres symmetrical, longer than phallobase, evenly curved and rounded with hump and deflection apically in lateral aspect; covered by short, fine, semierect yellow macrosetae.
Sexual dimorphism. Female differs from male in the following characters: vertex of head with small swelling, pronotum narrower with weak anteromedial depression ( Burgeon 1946).
Geographic distribution. Democratic Republic of the Congo, Equator region ( Fig. 10C View FIGURES 10 ).
Remark. This species was described based on two males. A lectotype is designated here to enhance stability of nomenclature (International Commission on Zoological Nomenclature, Article 74). The location of the paralectotypes is unknown.
