Previous records. Angola, China, Cyprus ( Papadoulis et al., 2009), Hong Kong, India, Indonesia, Malaysia, Philippines, Singapore, Sri Lanka ( Moraes et al., 2004a) and Thailand (Provinces of Bangkok, Chiang Mai, Chiang Rai and Phra Nakhon Si Ayutthaya, Ehara & Bhandhufalck, 1977).

Remarks. Measurements of the specimens examined are similar to those of the original description, but the lengths of Z4 and Z5 of females are closer to those reported for the allotype male and vice versa. This pattern was also observed by Ehara & Bhandhufalck (1977) for specimens from Thailand and for paratype females from Indonesia and Malaysia. The measurements here reported for females are also similar to those reported by Moraes et al. (2004a) for a specimen from Sri Lanka.
