Leptopelis vermiculatus (Boulenger 1909)

A large to very large (male 39-50 mm, female 61-85 mm) Leptopelis from the Eastern Arc Mountains and Rungwe, Tanzania with well developed webbing and a large tympanum. Males with pectoral glands. Phase A vivid green with fine black vermiculations, sides marbled in black and white. Phase B brown with an irregular darker triangle on dorsum with apex pointing forward, a dark bar or spot between the eyes, and sides heavily marbeled.All juveniles have the beautifil phase A and so do some of the males, while all the females collected by Schiøtz belong to phase B. Some specimens show a transition between the phases where the dorsum has an iridescent green coloration almost covering the phase B pattern. An adult male phase A kept in a terrarium changed within eight months to phase B. Specimens in phase B are very similar to L. flavomaculatus (Schiotz 1999).

A forest species, often found sitting quietly on branches above water. It is known from the eastern Usumbaras and from Rungwe Mts., but strangely enough not with certainty from Uluguru and Udzungwas (Schiotz 1999).

Voice- The voice is a single clack with a peculiar tonal quality resulting from a large number of harmonics about 250-300 cps. apart with a vibrato (Schiotz 1999).
