FIGURE 140
. Distribution of
Acylophorus orientalis
Fauvel
= typical form, = southern form).
Head large (pronotum 1.5x wider than head), 1.05x wider than long, temples well developed behind relatively small eyes (
Fig. 27
). Pubescence extending over most of head leaving only a central glabrous strip free of punctures. Two pairs of interocular setae. Five postocular setae visible, the posterior puncture and seta displaced forward and out of line. No additional short seta on hind margin of eye. Mandibles with three medial teeth on right and two on left (
Fig. 50
). Maxillary palpi with terminal segment elongate, glabrous, asymmetric and attenuated at apex (
Fig. 76
). First segment of antenna almost as long as next five (
Fig. 103
). Segments I to IX elongate, X transverse.
Pronotum slightly transverse (1.1x wider than long) with rounded sides and widest in basal half. Somewhat sparse semi-erect pubescence extending over most of surface except for central longitudinal glabrous strip and apical band. Dorsal setae absent. One pair of lateral setae. Marginal setae apparently short and reduced in number, though setae are possibly abraded in material available for study. Elytra transverse (1.6x wider than long) with pubescence arising from somewhat close asperate punctures. Apical fringe of thick bristles shorter than the hairs on the rest of the elytra. Abdominal tergites with long, somewhat outstanding pubescence arising from asperate punctures that are much denser at the base of each tergite than in the apical half.
Paramere simply lobed, pegs confusedly arranged at apex (Fig. 139). Median lobe narrowed at rounded apex, easily surpassing paramere.

Distribution and bionomics.
Only known from a single specimen collected in the
Democratic Republic of Congo
(

). There are no ecological data.
Comparative notes.
Similar to
A. kumbuiensis
,
but distinguished by the smaller eyes and the form of the aedeagus.
