Diagnosis

BODY LENGTH. 2.0–3.0 mm.

COLOUR. Body integument black, antennae, femora and tibiae dark reddish; vestiture of elytra generally consisting of recumbent, rounded or slightly longer than wide scales, forming a dark-brown square in basal half and between interstriae 5 of each elytron; rest of scales on elytra greyish to brown, paler near dark-brown square; vestiture of prothorax consisting of brownish scales, with 5 longitudinal whitish stripes.

HEAD. Rostrum slightly longer than head capsule + prothorax in lateral view, moderately downcurved, curvature stronger near base and near antennal insertion.

PROTHORAX. Slightly wider than long (w/l ratio: 1.06), widest before middle of length, sides greatly rounded in basal ¾.

ELYTRA. Distinctly rounded, widest before middle of length (w/l ratio: 0.79).

LEGS. Femora moderately clavate, armed with a distinct ventral tooth, tibiae straight. GENITALIA. Body of penis elongate (w/l ratio: 0.47), 0.8× as long as apodemes, sides straight, subparallel, apex truncate, moderately and regularly curved in lateral view (Fig. 5P).

Remarks

Smicronyx namibicus was wrongly described from Namibia due to a misinterpretation of the handwritten label of the holotype. The locality of this specimen is ‘Zanzib’ (Island of Zanzibar, Tanzania) and not ‘Namib’ (Namib Desert) as reported in Haran (2018). I thank Helene Perrin (MNHN) for highlighting this misreading.
