Type species.
Entypophana apicata
Moser, 1913
, by present designation.
Diagnosis.
Entypophana
differs from other schizonychine genera by combination of the following characters: Body elongate (length 14.9–20.0 mm), almost parallel-sided, weakly to moderately convex. Labrum transverse, deeply bilobed, lobes rounded. Clypeus transverse, anterior angles rounded. Frontoclypeal carina elevated, medially sinuate forward. Frontoclypeal suture straight or gently undulate. Occipital carina always present, prominent, medially elevated, laterally diminishing. Head including clypeus with species-diagnostic macrosetose punctation. Eyes small (combined width of both eyes is less than maximum width of frons between eyes) to large (combined width of both eyes exceeds maximum width of frons between eyes). Antenna with 10 antennomeres, club with three antennomeres. Terminal maxillary palpomere elongate, club-shaped. Pronotum transverse, widest behind midlength, with anteromedial 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 top and frontal edges impunctate and remaining parts with species-diagnostic macrosetose punctation. Elytra weakly to moderately convex, parallel-sided, rounded apically, apical angle approximately rectangular. Striae absent. Macropterous. Protibia narrow, tridentate, terminal spine inserted against medial tooth. Claws bifid, with ventrobasal teeth (
e.g.
,
Figs. 9A–F
). Parameres symmetrical, narrow or curved in lateral aspect, blunt or extended apically in dorsal or lateral aspect; apex with tuft of long, yellow macrosetae (
Figs. 7A–F
,
8A–F
).
Sexual dimorphism
. Female differs from male in the following characters: body slightly broadened posteriad; antennal club straight, considerably shorter; eyes small (width of both eyes combined shorter than maximum width of frons between eyes); anteromedial depression flatter.
Geographic distribution.
Central Africa
(
Democratic Republic of the Congo, Tanzania
,
Uganda
) (

).
Remark.
Moser (1913)
established his new genus
Entypophana
for two species:
E. apicata
Moser, 1913
and
E. biapicata
Moser, 1913
, but neither has been designated as the
type
species of the genus. To remedy this,
Entypophana apicata
Moser, 1913
is here designated as the
type
species of
Entypophana
.
