Hyperolius angolensis Steindachner, 1867 (fide Marques et al. 2018).

Remarks.

Depicted in Ahl (1931b: 421, fig. 294, probably ZMB 50089). The three type specimens of H. nossibeensis were originally inventoried in 1882 as "3 [specimen] Hyperolius vermiculatus Pts." under inventory number ZMB 10100. According to the ZMB inventory catalogue the specimens were collected by "Dr. M. Buchner" at “Lunda”.

Because of a reading error, assuming ZMB 10100 instead of ZMB 10101, a new label was written for this collection jar in the 1920s, for which erroneously the information of ZMB 10100 was adopted, viz. “Nossi-Bé” and "Museum Senckenberg". This transmission error and the specimens became the basis for Ahl’s (1930) new description of H. nossibeensis . In 1992, Frank Glaw ( ZSM) located the syntypes of H. nossibeensis in the ZMB collection. The jar with the label from the 1920s mentioned Mantidactylus granulatus from Nosy Be, ZMB 10100. Glaw and Vences (1993: 216) discussed the status and identity of H. nossibeensis , synonymized it with Hyperolius marmoratus and corrected the terra typica to "das Äthiopische Afrika" [Ethiopian Africa]. Subsequently the three syntypes were re-inventoried as ZMB 50098-50100. This was necessary as the inventory number ZMB 10100 had already been assigned to a specimen of " Mantidactylus granulatus " (= paralectotype of Limnodytes granulatus Boettger, 1881) from "Nosy Bé, don. Museum Senckenberg" (see Glaw and Vences 1993).

The physician Dr. Buchner arrived in Luanda on 5 December 1878 and travelled via Dondo (20 December 1878) and Malanje (30 January to 22 July 1879) to Mussumba in the Lunda Empire (11 December 1879 to June 1880). He returned to Malanje (28 February 1881) and via Golungo and Cazengo travelled back to Luanda, where he arrived at the end of August 1881. He finally returned to Berlin in January 1882 ( Heintze 2007).
