Ptomaphaginus anas Schilthuizen & Perreau, 2008  Figures 4a, 6 i–j, 9a

Ptomaphaginus anas  Schilthuizen & Perreau, 2008: 199, figs 16-17; type from Gombak, Selangor, Peninsular Malaysia (in RMNH).

Material.

(In addition to that given in Schilthuizen and Perreau (2008)): Sarawak. Kuching, Semongok, 1°24.7'N, 110°19.3'E, 16.i.1978, ( RMNH.INS.549311) 1 male.

Description.

(Adapted from Schilthuizen and Perreau (2008)). Medium-sized (2.3-2.9 mm) and dark-coloured species. Pronotum 1.65 times as wide as long, as wide as the elytra. Elytra 1.1 times as wide as their combined length (length measured from the caudal tip of the scutellum to the apex of the elytra). Winged. Aedeagus in dorsal view gradually narrowing towards the apex. The tip is triangular and subtly asymmetric. A broad medial furrow runs over the dorsal side of the aedeagus, and dissolves just short of the apex. In lateral view, the median lobe is strongly curved, almost semicircular, and distinctly thickened at the point of strongest curvature.

Differential diagnosis.

The aedeagus is characteristically shaped: strongly curved, distally tapering into a narrow, flattened, and slightly upturned apex. Ptomaphaginus louis  and P. muluensis  have a similar aedeagus, which, however, is less strongly curved in the terminal half.

DNA barcodes.

One individual ( RMNH.INS.549311; see under Examined material) is available in BOLD, but no DNA has been successfully sequenced from this specimen.

Habitat and distribution.

Lowland and lower montane forest, up to 1,500 m. Sabah: Batu Punggul, Kinabalu Park HQ, Kibongol; Sarawak: Semongok. Peninsular Malaysia: Gombak, Cameron Highlands.
