Raorchestes signatus from India

Raorchestes is a genus of frogs in the rowing frog family. They occur from southwest India via Nepal, Myanmar, Thailand, Laos, Vietnam, Cambodia and Malaysia to southern China. The greatest variety of species within this genus can be found in the Indian Western Ghats . Many species that are nowassigned to Raorchestes were before the genus was first described in 2010 in the genus Ixalus , which has since been dissolved, as well as in the genera Philautus and Pseudophilautus .

The species of the genus Raorchestes live on trees and have widened adhesive discs at the finger and toe ends, which make climbing easier for them. Similar to the tree frogs, they have an intermediate cartilage between the penultimate and last finger and toe phalanx, which allows the limbs to be pressed onto the surface in any position of the limbs.

They are relatively small frogs, the head-trunk length in sexually mature specimens is 15 to 45 millimeters, depending on the species. The males' throaty vocal sac is large and transparent as they call.

Reproduction and development

Raorchestes species, in contrast to most other genera of rowing frogs, have a direct development, so there is no tadpole stage. Instead, the larval development takes place within the eggs, which are laid in moist places on land, and ready-made young frogs hatch. Although the eggs still require high levels of moisture and dry out easily, this enables the frogs to colonize moist habitats without open water.

Systematics and taxonomy

The genus was first described in 2010 . The first part of the name of the genus, Rao , honors the Indian herpetologist C. R. Narayan Rao , the second part, Orchestes , recalls the generic name used by Tschudi in 1838 for frog species from the related Philautus group.

species

There are currently 63 species described.
