Hyperolius marmoratus Rapp, 1842.

Remarks.

Depicted in Ahl (1931b: 353, fig. 228). Ahl (1931a: 81) mentioned no collector or donor for the type specimens. However, the syntypes were mentioned earlier by Sokolowski (1903: 541 f.) who described two Rappia specimens collected by the botanist Baum on 14 January 1900 "am Longa oberhalb Minnesera" during the "Kunene-Sambesi-Expedition 1899-1900" led by Pieter van der Kellen. Based on Baum’s notes, Sokolowsy (l. c.) almost literally described the same observations, as was later repeated by Ahl (1931a: 81), i.e. “[…] kleine auf Blättern von Sträuchern nach Art unserer Laubfrösche sitzende Fröschchen [ …]” [ … small frogs sitting on leaves of bushes like our tree frogs …]. Baum’s expedition route in Angola was illustrated by Heintze (2007, map 2).
