Habitat and seasonal occurrence

This is a fairly common species that occurs in beach forests, mangroves and all types of terrestrial forests. Previously this species was reported from Kranji, Sungei Biloh, Sime forest and Nee Soon ( Shamshev & Grootaert 2007). It is present throughout the year, but with a higher activity in the second half of the year. The sex ratio of 0.5/1 indicates that females have a different activity pattern than males.

Species Complex 3. - Hind tibia lacking prominent bristles.

No new information was found on that group since Shamshev & Grootaert (2007).
