Notes

Types of Thinophilus calopus were collected from a sea coast; later the species was once reported from the National Park Albert (= Virunga), DR Congo, at a height about 1000 m above sea level, by Vanschuytbroeck (1951), far from the sea coast. RMCA collection contains three females identified by Vanschuytbroeck as T. calopus : two of them belong to the genus Tachytrechus and one specimen to an indeterminable species of Thinophilus . I think the species must be excluded from the fauna of the Democratic Republic of the Congo.

Thinophilus annulitarsis was described from a female collected on a beach at Dar Es Salam. It has never been recorded again.A male examined from Zanzibar’s beach, close to the type locality of T. annulitarsis , is identical to the female holotype (examined) and original species description ( Parent 1936) and to the detailed description of T. calopus by Loew (1862). One more male of this species was found at the site Mtwara, close to the Tanzania-Mozambique border. Therefore, I consider the two names as synonyms.

Distribution

Mozambique, * Tanzania.
