Diagnosis

BODY LENGTH. 2.0– 2.1 mm.

COLOUR. Body integument black; vestiture of elytra consisting of recumbent, slightly overlapping brown scales, slightly longer than wide, concealing integument, and white scales usually forming a pale oblique band between humeri and apical third of elytral suture.

HEAD. Rostrum moderately downcurved in lateral view, as long as head capsule + prothorax.

PROTHORAX. Slightly wider than long (w/l ratio: 1.15), sides moderately rounded in basal ¾, constricted in apical ⅓, with spots of whitish scales near humeri and at base near scutellum.

ELYTRA. Subparallel in basal two-thirds (w/l ratio: 0.65), rounded toward apex in apical third.

LEGS. Covered with white and brown scales; femora moderately clavate, armed with small but distinct ventral tooth, tibiae straight; claws unequal in length, at least for fore tarsi.

GENITALIA. Body of penis elongate (w/l ratio: 0.30), 1.2× as long as apodemes, sides straight, subparallel, converging near apex; curvature moderate in lateral view ( Fig. 5H View Fig ).

Life history

Smicronyx albosquamosus   is found across its distribution range on pods and flowers of Cuscuta   spp. Adults were collected in southern Africa from November to April.

Distribution

This species is widely distributed across Africa and the Mediterranean region. In the Republic of South Africa, this species is only found in subtropical areas (Gauteng, KwaZulu-Natal, Limpopo and Mpumalanga provinces)

Remark

The identity of this species was established by comparisons of specimens with reference material from the Mediterranean region reported by Haran et al. (2017).
