Figs 2 I – L View Figure 2 , 4 F View Figure 4 , 15 Q, R View Figure 15 , 20 C, D View Figure 20

Specimens examined.

Holotype: Malaysia: • Borneo Island, Sabah, Kinabalu Park Headquarters , alt. 1800–2500 m, 15. III. 1993, H. Hiratate, male deposited in KUM, JHLHY_DAR_077 .

Diagnosis.

Body length 1.9 mm. Cuticle coated in dark, sandy gray, and white scales in indistinct pattern. Funicle with six articles. Procoxae contiguous. Second and odd-numbered elytral intervals with erect scales. Erect elytral scales concentrated in small bundles of two or three along second elytral interval at midpoint; evenly distributed along other intervals. Elytral interval 5 + 6 not distinctly arched at base. Femora all with large, acute tooth along ventral edge. Scutellum distinct, bulging, and covered in white scales. Prosternal cavity prominent and with steep lateral ridges. Metaventrite with a distinct elevated transverse ridge separating the meta- and mesocoxae. Metatibial uncus of male claw-shaped (Fig. 2 I – L View Figure 2 ). Aedeagus with diagnostic, laterally expanded apex (Fig. 15 Q, R View Figure 15 ). Internal sac with M-shaped, basal protruding structure (Fig. 15 Q, R View Figure 15 ).

Distribution.

This species is only known from one site in Kinabalu Park, Borneo.

Etymology.

This specific name spinosus is a Latin adjective in reference to the distinctly acute, elongate tooth on the ventral side of the femora.

Comments.

Although the female is unknown it is likely the case that the metatibial uncus is sexually dimorphic as in other closely related Aphanerostethus species.
