It has been collected only twice, seventy years apart. Current Population Trend: Unknown

Habitat and Ecology (see Appendix for additional information) There is no information specific to this species. Members of the genus, typically recorded in or around bamboo grooves, and often cope with cultivated habitats. A specimen was collected in bamboo by A. Suyanto (U. Sinaga pers. comm). It is not usually dependent on water and it probably lives in small colonies. Other specimens determined as belonging to this species in the collections of RMNH and MZB proved to be represent different species (Csorba 2011).

Systems: Terrestrial

Threats The threats to this species are not known, but habitat loss in the lowland regions could be a threat, assuming its reliant on primary habitat.

Conservation Actions (see Appendix for additional information) This species has been collected by A. Suyato from Gunung Halimun National Park (U. Sinaga pers. comm.). Further research to determine the species' range, population status, habitats and threats is needed. Credits
