Hyperolius brevipalmatus Ahl, 1931a: 25.

Holotype.

ZMB 24499, "Sangmelina, Süd Kamerun" [ Sangmélina, Lobo Division, South Province, Cameroon], purch. Franz Hermann Rolle.

Present name.

Afrixalus brevipalmatus Ahl, 1931a.

Remarks.

Drawing in Ahl (1931b: 279, fig. 150). Perret (1976b: 21) listed two specimens, i.e. ZMB 24499 and ZMB 20132, as syntypes of H. brevipalmatus Ahl. However, Ahl’s description is clearly based on a single specimen "1 Stück [piece]" from “Sangmelina” purchased from “Rolle”. Furthermore, the collection data of ZMB 20132 from “Bipindi” [Bipindi village, Océan Department, South Province, Cameroon], coll. Georg August Zenker, do not match the information provided in the original description.

Rolle was a well-known dealer of zoological and enthnological objects. He maintained a worldwide network of collectors and suppliers and acquired several important collections. From 1889 onwards, he supplied private collectors as well as important European museums with zoological objects from Berlin. In later years, he traded objects under the name of the natural history institute “Kosmos”.
