Direct development has evolved in rhaco- phorine frogs independently from other anuran lineages, thereby offering an opportunity to assess features associ- ated with this derived life history. Using a developmen- tal series of the direct-developing Philautus silus (Ranidae: Rhacophorinae) from Sri Lanka, we examine features of cranial morphology that are part of a suite of adaptations that facilitate feeding in free-living tadpoles, but have been changed or lost in other direct-developing lineages. Larval-specific upper jaw cartilages, which are absent from many non-rhacophorine direct-developing species (such as Eleutherodactylus coqui), develop in embryos of P. silus. Similarly, lower jaw cartilages ini- tially …

A distinctive new species of Gastrotheca from the Rio Chanchamayo Valley in the Cordillera Oriental in Peru is the only known member of the genus that lacks a tympanum. Another new species from the Cordillera de Carpish is distinctive in having a pair of lateral brood pouches and only basal webbing on the foot.
