Hyperolius vermicularis Ahl, 1931a: 24.

Syntype.

ZMB 10988, “Zanzibar” [Unguja Island, Tanzania], coll. Franz Ludwig Stuhlmann.

Present name.

Hyperolius marmoratus Rapp, 1842.

Remarks.

Hyperolius vermicularis Ahl is a nomen novum pro Rappia vermiculata Pfeffer, 1893 which is preoccupied by Hyperolius vermiculatus Peters, 1882a. A copy of Pfeffer’s (1893, pl. 1, fig. 12) drawing is depicted by Ahl (1931b: 275, fig. 145). Pfeffer (1893) mentions two specimens (catalogue no. “352”) from "Sansibar, Insel", collected by Fülleborn on 6 August 1888. The type specimens of Rappia vermiculata are not mentioned in the herpetological type catalogues of ZMH ( Hallermann 1998, 2006). A new search in ZMH collection also failed to locate the type material (Jakob Hallermann in litt. 29 July 2020). ZMB 10988 was inventoried as " Rappia vermiculata Pffr." collected by Stuhlmann, allegedly at “Quillimane”. However, Tornier (1896: 141) stated that the locality is “Zanzibar” and depicted this juvenile specimen on plate 4, figure 34.
