Blommersia angolafa is a species of frogs in the family Mantellidae. This recently described species is endemic to eastern Madagascar. The specific epithet is derived from the term “angolafa” or “angolafo”, which is the Malagasy vernacular name used by the Betsimisaraka people for the Dypsis palm species (mostly for Dypsis lastelliana), whose leaves and prophylls are the habitat for this frog. Description Blommersia angolafa is a small frog, with a body size of 17–21 mm, enlarged tips on fingers and toes, and without any dark area in the tympanic and frenal region, present in the other Blommersia. B. angolafa has a rather uniform dorso-lateral colouration, shading from yellowish–light brownish to dark brown, with light-bluish spots on the flanks and light-bluish terminal parts of the fingers and toes. The species also appears to be chromatically sexually dimorphic. In fact, males differ from females in having a light colouration, while females are more brownish. Blommersia angolafa is similar to B. grandisonae. Although both B. angolafa and B. grandisonae have enlarged finger tips, they are much more developed in B. angolafa. Eggs and tadpoles Egg clutches are found only from December onwards; they are glued to the inside walls of palms' dead prophylls filled with water and fallen on the ground. Several different stages of tadpoles can be found sharing the water accumulated within the same fallen prophyll. Under captive conditions, all the eggs of a single clutch hatched after a period of 7–10 days, and the total duration of the larval development was 57–70 days. Distribution and habitat Blommersia angolafa occurs at four forest blocks in eastern Madagascar: Masoala, Ambatovaky, Zahamena and Betampona and occupies rain forest with an elevation range between 90 m (Ankavanana River, Masoala Peninsula) and 508 m (Vohitsivalana, RNI de Betampona). It is found both in primary and secondary forest, due to the tolerance of some Dypsis palms to occur in secondary rain forest at Betampona. The observed elevational distribution at Betampona ranged from 332–548 m asl. Andreone et al. suggest that this species may also occur at other rain forest sites that fall within this elevational and latitudinal range for eastern Madagascar, such as Makira and Mananara Nord. Life history, activity and special behaviours A peculiar aspect characterising this species is its novel life history and reproductive mode. Both sexes live and breed in a phytotelmic habitat of water accumulated within fallen prophylls and fallen leaf sheaths
