Pseudochirista longicornis Ramme, 1931: 921, 927, pl.11, fig. l. (Transferred to Gymnobothrus by Uvarov 1953: 122).

Material.

-Holotype male longicornis : CENTRAL AFRICAN REPUBLIC: Bosum, Sanga-Lobadje.

Description.

-As defined in the key above.

Discussion.

-The various subspecies in this complex include several closely related taxa which are distributed across western Africa to East Africa and south to ANGOLA. In view of their close similarity and occurrence of clinal links between these species, they are here reduced to the level of subspecies under longicornis Ramme. It is conceivable, however, that two other extant taxa, oberthuri I. Bolívar, 1890 and romeri (Karny, 1909), from Tabora and Amani in TANZANIA respectively (not reviewed here as no material was available), could also belong to this group and thus in due course take precedence as older synonyms of longicornis .
