Cuticle dark red and largely bare; covered unevenly with yellow scales. Funicle with six articles. Procoxae contiguous. Eyes dimorphic (connected at base of rostrum in male; separated in female). All elytral intervals with erect scales. Erect elytral scales evenly distributed, not concentrated in bundle. Scutellum reduced. Femora without ventral tubercle or tooth. Prosternal cavity very weakly defined and without steep lateral ridges. Metaventrite flattened between meta- and mesocoxae, without a distinct elevated transverse ridge. Metatibial uncus weakly spiral-shaped in male (Fig. 2 M – P ). Aedeagus wide at midpoint, and tapering near apex (Fig. 15 O, P ). Internal sac with basal protruding structure (Fig. 15 O, P ). Distribution. This species is currently only known from Malaysia (Brinchang). Etymology. The specific name nudus is a Latin adjective that refers to the distinctly naked (unscaled) cuticle of this species.
