Remarks.

Depicted in Tornier (1896, pl. 4, fig. 100 and 101) and partly redrawn in Ahl (1931b: 332, fig. 205).

The name Rappia fimbriata Tornier (1896: 153, pl. 4, figs 100, 101) is categorized as nomen inquirendum, "Name(s) unassigned to a living or extinct population" by Frost (2021). Tornier (1896) attributed the authorship of this name to "B e P" which refer to Buchholz and Peters instead of “Duméril and Bibron" as claimed by Frost (2021). Tornier (l.c.) mentioned the type material as collected at "Gowe Limbareni", a writing error for "Limbareni am Ogowe [river]" (Peters 1876). However, Buchholz and Peters never together described a reed frog with the specific epithet " Rappia fimbriata ". Tornier’s name Rappia fimbriata does not meet the requirements of Art. 33.2 of the ‘Code’ (ICZN 1999) for an “emendation” . We therefore consider Rappia fimbriata Tornier, 1896 as an incorrect subsequent spelling of the specific epithet fimbriolata Buchholz & Peters in Peters, 1876.
