Hyperolius baumanni Ahl, 1931a.

Remarks.

Drawing in Ahl (1931b: 291, fig. 167). According to Ahl (1831a: 35) the original series consisted of four specimens, i.e. one collected on 26 July 1894 and three on 07 May 1893. However, the latter year given by Ahl is most probably a typographical error. According to Baumann’s preserved original field label, the date of collection was the "7. Mai 1894". Another paratype MCZ A-17627 from “Misahöhe, Togo", coll. Baumann on 07 May 1894, was sent in exchange from ZMB in 1932 ( Barbour and Loveridge 1946: 127). The latter specimen was erroneously regarded as a holotype by Seniagbeto et al. (2007: 77).

The natural scientist and cartographer Baumann joined the German Colonial Service in 1893. He worked at Klein Popo [ Aného, Lacs Prefecture, Maritime Region, Togo] and was later stationed at Misahöhe [Agou Prefecture, Plateau Region, Togo] where he was deputy station chief from 1894-95. In November 1894, he accompanied the “Togo-Hinterland-Expedition” headed by the colonial officer Hans Gruner along the Volta River to Kete Kratschi [Kete Krachi, Oti Region, Ghana] and returned to Misahöhe. In the hinterland of the station (Agome Region) he collected zoological, botanical and ethnological objects, which were given to the museums in Berlin. In 1895 he returned to Germany where he died on 4 September as a result of malaria that he contracted on his return journey ( Danckelmann 1895; Reichenow 1897; Heß 1902; Hafeneder 2008).
