The tree frogs of the taxon Rhacophoridae are known for their impressive diversity of reproductive strategies. Direct development on land has been described in the Old World Bush Frogs belonging to the genera Philautus, Pseudophilautus, and Raorchestes. However, in numerous species especially within the Bornean Philautus, breeding behaviours remain unknown. In this paper, we match a clutch of eggs found on Gunung Mulu National Park, Sarawak, Malaysia (Borneo), using genetic barcoding to syntopically occurring adults of Philautus acutus. This species is known only from its type locality in the montane forests at high elevations on Gunung Mulu. The eggs were found on leaf litter of the forest fl oor and are characterised by a protective, compact, outer jelly capsule. The froglets inside the eggs were at advanced stages of development and showed a bifurcating dorsal pattern similar to adults of P. acutus. Beside the discovery of its breeding behaviour, we add a description of the habitat of this rare species. Furthermore, this account of aerial direct development in a Philautus species from Borneo contributes to our understanding of the evolution of reproductive strategies within the lineage. Finally, we present a review of observations of the breeding behaviour in Bornean Philautus species available in the literature. [ABSTRACT FROM AUTHOR] |
