Ptomaphaginus caroli Schilthuizen & Perreau, 2008: 193, figs 14-15, 26; type from Gunung Mas, Sabah, Borneo (in RMNH).

Description.

(Adapted from Schilthuizen and Perreau (2008)). Length 2.7 mm. Habitus relatively slender and narrow, flat. Pronotum 1.62 times as long as wide, slightly narrower than the elytra. Elytra 1.41 times as long as their combined width (length measured from the caudal tip of the scutellum to the apex of the elytra). Winged. Long setae on the ventral side of the male profemur and protibia absent. Aedeagus apically with two short ‘wings’ and a very small, indistinct terminal processus. Spiculum gastrale long-triangular, the apex nearly truncate, with a small central projection; similar in shape to P. latimanus and P. similipes .

Differential diagnosis.

Ptomaphaginus caroli has a similar aedeagus as P. bryanti , P. similipes , and P. bryantioides . However, it differs in having a distinctly elongated habitus (elytral index of 1.41) and very short apical ‘wings’ on the aedeagus.

Habitat and distribution.

So far, only known from the type specimen, collected in lower montane forest at 1350 m in the Crocker Range of Sabah. The aedeagal shape shows that it belongs within the " bryanti -group".

Remarks.

The aedeagus of the holotype has been lost shortly after it was first collected and studied (in 2000). Before the loss, sketches were made of the dorsal and lateral view of the aedeagus, which form the basis for the line drawing in Figure 8 and in Schilthuizen and Perreau (2008).
