Remarks. Zwick (1982) reported this species from several Malaysian and Thai sites and additional localities were given in Zwick & Sivec (1985). The latter study includes specimens from Sumatra which have egg collars markedly different from mainland specimens. In our experience this much variation in such a structure suggests more than one species is involved. In our opinion various populations of P. simplex should be carefully re-examined when material becomes available.
