Two new arboreal microhylid frogs are described from the rainforests of northeastern Madagascar. Platypelis tetra is a very small frog, reaching about 20mm SVL, and inhabits phytotelms in screw Pandanus pines. It was found in some low and mid-altitude rainforests, such as Anjanaharibe-Sud, Besariaka, Tsararano, and Masoala Peninsula. This species diverges from the other Platypelis by its small size and colouration, with a series of whitish spots on the back, of which four are more evident. Furthermore, its advertisement call is composed by a long series of discrete notes at about 3.5-4KHz of frequency, and a repetition rate of about 3.0 notes/s. The second species, Platypelis mavomavo, reaches a larger size (about 30mm SVL), and is characterized by a yellowish colouration of the ventral surface, and a dorsal surface with a network of dark spots on a beige-yellow background. It is currently known from Anjanaharibe-Sud and Ambolokopatrika, around the Andapa water-basin, but is expected to have a wider distribution.

Although laboratory trials suggest that stick insects (Phasmatodea) are a highly palatable prey group for spiders, field observations confirming this hypothesis are very rare. We report on a predatory event involving a huntsman spider of the genus Damastes (Araneae: Sparassidae) on a stick insect of the genus Antongilia (Bacillidae: Antongiliinae) from Madagascar. Despite the anti-predator adaptations that characterise this insect group (e.g. the cryptic camouflage) the stick insect was recognized and overwhelmed by the sparassid spider.
