Entypophana apicata Moser, 1913: 296 (description); Burgeon, 1946: 264 (comparison with E. lujai and E. maynei).
Type locality. “Uganda (Entebbe)”.
Type material. Holotype (designated by monotypy), ♂, labelled: “Entebe, Uganda / Centr. Afr. [white label, printed] // Entypophana / apicata / Type Mos. [white label, handwritten]”.
Type depository. ZMHUB.
Additional material examined (2 specimens). Uganda: Uganda East, Rwenzori Mt., Nyakalengija, 1- 3.i.2006, Lgt. P. Macháček, 1 ♂ in RSCV; Zobia [= about 20 km W of Entebbe], 1939, R. P. Van Woensel, 1 ♀ in IRSNB.
Redescription of holotype (♂). Body length 16.6 mm, elongate, almost parallel-sided, strongly convex. Dorsal and ventral surfaces weakly shiny, elytra reddish brown, macrosetation pale (Fig. 1A). Dorsal surface of head, pronotum, scutellum, and elytra covered with recumbent, short, white, scale-like 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, randomly weakly punctate; lobes covered with long, erect macrosetae. Head including clypeus smooth, glossy, punctate, with setae markedly exceeding puncture diameters. Frontoclypeal carina elevated, medially sinuate forward, basal side impunctate. Frontoclypeal suture straight or gently undulate. Space between frontoclypeal carina and suture sparsely punctate. Occipital carina always present, prominent, medially elevated, with oblique summit, laterally diminishing (Fig. 1B). Space between summit and frontoclypeal suture triangular, without punctures or setae. Occiput 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.
Pronotum transverse, widest behind midlength; with anteromedial, evenly semicircular depression. 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 and toward base impunctate and remaining parts with macrosetose punctation – round punctures with yellow, scale-like, semirecumbent setae twice as long as puncture diameters (Fig. 1C).
Scutellum large, almost equilaterally triangular, sides and apex rounded; glabrous.
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, punctures almost evenly spaced, separated by twice their diameter; each puncture with somewhat recumbent, long (twice puncture diameter), narrow, yellow macroseta. Epipleuron distinct, complete, narrow, laterally glabrous. Macropterous.
Legs with femora narrow, shiny, irregularly punctate, macrosetaceous. Protibia narrow, distinctly tridentate, terminal spine inserted against medial tooth. Mesotibiae and metatibiae slightly expanded distally, with one macrosetiferous longitudinal carina. Upper terminal spine of metatibia flattened, slightly curved, acute apically; almost as long as lower, apically trunctate, chisel-shaped metatibial spine. Claws bifid, with ventrobasal teeth (Fig. 9A).
Ventrum 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. 7A, 8A). Parameres symmetrical, longer than phallobase, evenly curved and with hump apically in lateral aspect; covered by short, fine, semierect, yellow macrosetae.
Sexual dimorphism. Female differs from male in the following characters: body length 17.9 mm; metatibia more strongly expanded apically; tarsomeres of all legs shorter.
Geographic distribution. Uganda (Fig. 10A).
