Type material. Holotype female ( TNHM), ex P. sulphuratus , TRINIDAD: Tumpuna Rd., 25 Aug 1960, TRVL 4725, Brit. Mus. 1974­636. Paratypes ( OSU): 3 females, 2 males, ex P. sulphuratus , COSTA RICA: Guanacaste, Zapote, Bijagua, Canas, 20 Jul 1985, M. A. Marin 280.

Remarks. This species is readily separable from others of this species group by the large dimensions of both sexes coupled with the lengths of the postspiracular setae and the large number of sternal setae on IV–VI.
