Redescription of lectotype ( ♂ ). Body length 17.2 mm , elongate, almost parallel-sided, strongly convex. Dorsal and ventral surfaces weakly shiny, elytra reddish brown, macrosetation pale ( Fig. 2A ). Dorsal surface of head, pronotum, scutellum, and elytra covered with short, recumbent, scale-like, white macrosetae; ventral surface of thorax and abdomen with recumbent, long, yellow macrosetae. Head appendages and legs covered with moderately long, yellow macrosetae. Head with labrum transverse, deeply bilobed; lobes rounded, unevenly weakly punctate; lobes covered with long, erect macrosetae. Head including clypeus smooth, glossy, densely coarsely punctate, with each puncture bearing an erect macroseta shorter than puncture diameter. Frontoclypeal carina elevated, medially sinuate forward; base as punctate as clypeus. Frontoclypeal suture undulate, medially arched toward occipital carina. Occipital carina always present, prominent, medially with two rounded summits, laterally diminishing ( Fig. 2B ). Space between summits and frontoclypeal suture triangular, without punctures or setae. Occiput evenly, moderately punctate. Canthus narrow, short, glabrous. Combined width of both eyes approximately equals maximum 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. FIGURES 2A–D. Entypophana biapicata Moser, 1913 male, lectotype; length 17.2 mm. A, dorsal view; B, detail of head, anterior view; C, head and pronotum, dorsal view; D, labels. Not to scale. Pronotum transverse, widest behind midlength, with anteromedial semioval depression widest and flat in anterior third and then gradually reclined 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. Anterior part of pronotum deeply punctate, punctures separate, setae no longer than puncture diameters. Remaining parts similarly punctate but punctures shallow; setae yellow, scale-like, semirecumbent, no longer than puncture diameters. Scutellum large, almost equilaterally triangular; sides and apex rounded; sides punctate; each puncture bearing short, narrow, scale-like, semirecumbent, white macroseta ( Fig. 2C ). Elytra weakly convex, parallel-sided, rounded apically; apical angle approximately rectangular. Striae absent except weakly indicated sutural stria. Humeral umbones present, weakly swollen. Surface not microsculptured, moderately shiny; punctation coarse, almost evenly spaced; punctures separated by twice their diameter. Each puncture bearing narrow, scale-like, semirecumbent, yellow macroseta as long as puncture diameter. Epipleuron distinct, complete, narrow, glabrous laterally. Macropterous. Legs with femora narrow, shiny, unevenly punctate, macrosetaceous. Protibia narrow, distinctly tridentate; terminal spine inserted against 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 spine. Claws bifid, with ventrobasal teeth ( Fig. 9B ). 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. 7B , 8B ). Parameres symmetrical, longer than phallobase, evenly curved and apically rounded with double hump in lateral aspect, with single apex in dorsal aspect; covered by short, fine, semierect, yellow macrosetae. Sexual dimorphism . Female differs from male in the following characters: body length 15.6–18.4 mm . Geographic distribution . Tanzania , Tanga Region ( Fig. 10B ). 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). The location of the paralectotypes is unknown.
