Redescription.
Length
7mm
. Body brown with head darker. Legs and palpi pale, antennae brown with paler terminal segments.
Head large (pronotum 1.5x wider than long) slightly transverse (1.1x wider than long), temples well developed (Fig. 23). Area in front of antennal insertion pigmented. Micro-punctures very sparse. Short dense pubescence behind eyes. Three pairs of interocular setae and a line of five postocular setae visible from above on each side. Maxillary palpi with last two segments densely pubescent, terminal segment much more rounded on outer margin than inner margin, so markedly asymmetric, longer than penultimate segment which is also elongate (
Fig. 72
). First segment of antenna as long as next five. Segments I to V elongate, VIII to XI transverse (
Fig. 99
).
Pronotum transverse (1.2x wider than long) with rounded sides and widest at centre. Shining with no micro-punctures. One pair of dorsal and one pair of lateral setae. Marginal setae long and more numerous than in
A. orientalis
. Elytra transverse (1.6x wider than long) with long pubescence, asperate punctures stronger but less dense than in
A. orientalis
. Apical fringe of bristles much longer than hairs on the rest of the elytra. Scutellum markedly less strongly punctured than elytra. Abdominal tergites with very long and semi-erect pubescence, asperate punctures much weaker and sparser than on elytra. Punctures on apical tergites much sparser than on proximal segments. Apical fringe of bristles on each tergite of equal length. The form of the aedeagus is unknown.
