We provide an expanded description of the tadpole of Amnirana albolabris (Ranidae) that includes external linear morphometrics and colouration across a developmental series ranging from Gosner stages 26–42. This description is based on material collected in Batéké Plateau National Park in south-eastern Gabon. The diurnal tadpoles are strikingly bright orange in life, a colouration that provides effective crypsis for the tannic waters in which they live. We also provide a comparative table for all of the described Amnirana tadpoles. The tadpole of A. albolabris can be identified in life by its unique colouration or in preservative by the seven prominent skin glands, assumed to contain defensive toxins. [ABSTRACT FROM AUTHOR]

The article focuses on a study which examined the external morphology and osteology of type of material of Phrynobatrachus nlonakoensis within the genus Arthroleptis to support a taxonomic change. External examination of the specimens showed that the species exhibits only a inner metatarsal tubercle and lacks a mid-tarsal tubercle and an outer metatarsal tubercle. The presence of rudimentary webbing on the feet of the species was previously described indicating that this species may have been assigned correctly to the genus Phyrnobatrachus.
