Description.

Length 2.3-3.0 mm. Habitus slender, ovoid. Pronotum 1.68-1.86 times as wide as long, as wide as the elytra. Elytra 1.2-1.3 times as long as their combined width (length measured from the caudal tip of the scutellum to the apex of the elytra). Winged. Aedeagus short and wide, with two elongated apical, laterally directed ‘wings’ and a short terminal processus. Spermatheca thin, broadly bent over a 90° angle, slightly bulbous at the basis and with several indistinct annulations at the terminus. Spermiduct long, narrow, with numerous coils. Antennae short, as long as the width of the head. Long setae on the ventral side of the male profemur and protibia absent. Female elytral apices drawn out, male elytral apices rounded, not truncated. Male with a central extension on the 4th visible abdominal sternite.

Differential diagnosis.

Similar in aedeagal shape to P. bryantioides  , but very different in habitus, which is more slender in P. kinabaluensis  . Furthermore, P. kinabaluensis  has only slightly dilated male protarsi, no setae on the male profemur and protibia, and extended elytral apices in the female.

DNA barcodes.

For the following specimens, DNA barcodes are available in BOLD: RMNH.INS.555601-555606 (Kinabalu Park HQ), RMNH.INS.555629, 555631 (Gunung Alab). RMNH.INS.549265-549267 are available in BOLD, but we have not yet succeeded in obtaining DNA sequences for them.

Habitat and distribution.

In montane forest at 1400-1930 m. Sabah: Kinabalu Park (around Park HQ), Crocker Range Park (Gunung Alab and km 51 KK-Tambunan road). The Crocker Range and Kinabalu populations are genetically very similar (BOLD BIN ACK0160).
