P. apiculatus sp. n., found in the Pacific coastal states of Mexico, is described and illustrated (holotype male and allotype female: Nayarit State, Mexico, are deposited in Mus. Zool., Univ. Michigan, Ann Arbor, USA). The previously undescribed female of the closely related P. pacificus is also described, the neallotype designated and deposited in the same institution. Because of the close resemblance of P. paciftcus to the present new sp. and several others yet to be described, and the considerable amount of historical uncertainty in the literature concerning its status, the type of P. paciftcus was borrowed for study. Brief notes on the ecology and behavior of P. apiculalus sp. n. are added.
