Previous records. Cosmopolitan, including Thailand (Provinces of Bangkok, Chiang Mai, Nakhon Pathom and Nakhon Ratchasima, Ehara & Bhandhufalck, 1977).

Remarks. Measurements of the specimens examined are similar to those reported by Denmark & Muma (1989) for a specimen of unspecified origin. However, our specimens differ by having longer Z5 (266–272 instead of 206) and cervix of spermatheca (23 instead of 18). Moraes et al. (2000) had also observed such differences for specimens from the Caribbean. Our measurements agree with those reported by Moraes et al. (2000) and Schicha (1981b) for specimens from the South Pacific, Moraes et al. (2004a) for specimens from Sri Lanka and Zannou et al. (2007) for specimens from sub-Saharan Africa.
