All tadpoles were collected from small to medium-sized forest streams. The description is mainly based on ZMB 82112 and ZMB 82115. The latter specimen was the bases of the description by Channing et al. (2012). The N. corrugatus tadpole was first described by Amiet (1971). The genotyped tadpole has been compared with an adult from the vicinity of Ediensoa, Cameroon (GenBank DQ 283361). The two sequences were identical.	en	Griesbaum, Frederic, Hirschfeld, Mareike, F.
