Previous records. China, Hong Kong, Japan, New Caledonia, Papua New Guinea, Philippines, Singapore, Taiwan and Thailand (Provinces of Chiang Mai and Kanchanaburi, Ehara & Bhandhufalck, 1977).

Remarks. Measurements of the females examined are similar to those of the original description and those reported by Ehara & Bhandhufalck (1977) for specimens from Thailand. Unlike what was reported by Corpuz & Rimando (1966), females examined have a pair of pores on the ventrianal shield; these are small, difficult to see and located posterior and slightly mediad to JV2. Measures of males are similar to those reported by Ehara & Bhandhufalck (1977) for specimens from Thailand.
