Type material. Holotype, male(?): Madagascar, Parc National d’Ankarafantsika , 40 km NW Andranofasika, in Malaise trap, B. Fischer, leg. 2001, BLF3520 . Holotype is deposited in CAS .

Diagnosis. Stout species, 2.1 × long as wide; interstrial setae short and broad, truncated, on interstriae 1 with multiple confused rows, on 2 and 3 only slightly so; interstriae 4–7 not reaching elytral apex but striae 3 on declivity.

Description, male(?). Length 1.3 mm, 2.1 × long as wide; colour black. Frons flattened to lightly concave, more so just above epistoma; surface rugose-reticulate, vestiture consisting of evenly distributed, short, erect setae. Eyes separated above by 3.3 × their width. Antennal scapus small, rounded, with a fine tuft of few setae as long as the antennal club; club with two transverse or weakly procurved sutures. Pronotum broader than long, anterior half strongly asperate, posterior half smooth or finely rugose; vestiture consisting mainly of evenly distributed, coarse, spatulate setae, fewer and very fine setae intermixed. Elytral interstriae 2–8 with regular rows of very closely placed, truncated, short spatulate setae, on interstriae 1 and posterior part of 9 and 10 with multiple confused rows; interstriae 4–6 not reaching apex but terminates on striae 3 on declivity. Protibiae with three lateral denticles.

Etymology. The Latin nominative adjective plenus means plump or filled, referring to the very stout body shape of this species.
