; several efforts have been made to obtain more material but failed. This is because of the “International Coastal Cleanup Program” of clearing “unsightly” timber and polyethylene bags from the mangroves since 1997 (Ng &amp; Sivasothi, 1999), which effectively removed the air filled cavities which are inhabited by many enigmatic arthropods.

It can be distinguished by the thorax having lesser and shorter setae and shining disc-like plates, by the scent gland orifice situated slightly behind middle of mediotergite IV, and by the concave posterior margin of male abdominal segment VIII. Other differences between the two species are summarised in Table 1.
