Raorchestes ochlandrae

Raorchestes ochlandrae (common name: Ochlandrae reed frog) is a species of shrub frog in the family Rhacophoridae. It is endemic to the Western Ghats, India. This species of the oriental shrub frog was first described from Kakkayam Reserve Forest of Calicut district, Kerala state, in the southern Western Ghats in 2007 but has since been recorded at many other sites along the Western Ghats. The specific name ochlandrae refers to microhabitat of the species, bamboo Ochlandra setigera.

Appearance

Males measure 22–26 mm (0.87–1.02 in) and females, based on only one measured specimen, 23 mm (0.91 in) in snout–vent length. The female was observed in amplexus and was larger than the male it was paired with.

Mating Habits

The Ochlandrae reed frog has a unique breeding habit of nesting within the hollow internodes of Ochlandra bamboo culms. Although they have been recorded in internodes of different Ochlandra species, breeding has been recorded so far in Ochlandra setigera. The frogs enter the hollow culms through small holes. Calling males may sit outside the entrance holes. While the entrance holes are towards the bottom of the internodes, eggs are deposited on the inside wall of the bamboo towards the upper side. A clutch size of six eggs has been reported. The presence of frogs in the bamboo indicates parental care by males in this species as in the similar Raorchestes chalazodes, with both species also showing direct development of eggs into juveniles.
