Named after Sri Lankan taxonomist Rohan Pethiyagoda , the frogs of the new genus Rohanixalus are characterised by a rather small and slender body (size about 2 to 3 cm long). Hence Option 1 is Correct . Based on DNA studies, the new genus is also revealed to be a distinct evolutionary lineage from all previously known tree frog genera . There are eight frog species in this genus Rohanixalus . They are known to inhabit forested as well as human-dominated landscapes right from the northeast to Myanmar, Thailand, Malaysia, Indonesia, Vietnam, Laos, and Cambodia, up to southern China . The genus has several unique behavioural traits including maternal egg attendance where the female (mother) attends the egg clutches until hatching and assists in the release of the tadpoles into the water . During the first three days after egg-laying, the female sits over the eggs and produces a gelatinous secretion with which she glazes the egg mass through the clock-wise movement of her legs. This behaviour provides necessary moisture to the eggs laid on exposed leaf surfaces and protects them from insect predation.
