Trichodela Rivalier, 1957 (Rev. Fr. Entom. 14: 342)

The known species of this genus are illustrated in Werner (2000b). The group of Trichodela nubifera was revised by Cassola (1995). It is represented in Angola by a single 1 species.

New localities reported: 75 km N Caconda (near Cuima) and 75 km NE Caconda (HUAMBO) (280) (P. Schüle pers. comm.).

Material examined: Duque de Bragança (Bayão), 1♀, white label with black margin, without reg. nº, “Old Collection” MZUC.

Remarks. A species found in southern D. R. of the Congo and Angola (Werner 2000b). In Angola it is well spread throughout several northern and central provinces. We were unable to locate precisely the collections site on the Kuiva River and the locality of Kasenya mines. Cassola (1995) made a brief redescription of this species and gave a list of material examined by him including the type specimen of Quedenfeldt. Interestingly the MZUC specimen (Fig. 2 B) belongs to the same lot of material collected by Bayão in Duque de Bragança (now Calandula). Wellman & Horn (1908) found that “this species occurs almost entirely on feldspathic soil, against which its indistinct light-colored markings make it impossible to see, except when it is in motion”. Peter Schüle (pers. comm.) found it in open secondary forests.
