Diagnosis. Body length 1.8–2.0 mm. Head black, pronotum dark brown, elytra dull brownish yellow with indistinct brownish borders and more indistinct brownish marking halfway along elytra. Frontal furrows shallow. Elytra with three shallow striae, remaining striae almost invisible.

Comments on classification. Rather similar to T. grandicollis (Chaudoir, 1846) which is known from Caucasus, the Middle East, Arabia and North Africa, with elytra of same colour as pronotum. According to BRUNEAU DE MIRÉ (1963) T. nigrolimbata is smaller and shorter than T. grandicollis , with paler elytra, and with frontal furrows shallower.

Collection circumstances. In 2009 all specimens were collected on the banks of the wadis, near the water.

Distribution. Known from Africa south of the Sahara, Madagascar, Morocco and Egypt. First record from Socotra Island.
