Diagnosis. Ascoids each with a long proximal branch reaching or exceeding the proximal margin of the flagellomere. Male: paramere thin with sinuous setae in ventral margin of apical portion (directed toward gonopod). Female: cibarium with 6 or more horizontal teeth, numerous vertical teeth irregularly placed, with the central teeth more robust compared to those at the edge, arch complete and pigmented area extensive; spermathecae cylindrical, annulated, longer than individual spermathecal ducts and as long as common duct. Female is indistinguishable from that of Pa. cratifer (Fairchild & Hertig) .

Material examined. MEXICO: CHIAPAS: Guadalupe Miramar, 17-ii-2010, 1 ♂. Collected with CDC light trap.

Distribution. MEXICO (Chiapas, Oaxaca, Veracruz), BELIZE, GUATEMALA, HONDURAS, EL SALVADOR, COSTA RICA, COLOMBIA, ECUADOR (Young & Duncan 1994; Alexander et al. 1996; Ibáñez- Bernal 2002).

Remarks. Males are easily distinguished from other species by the shape of the parameres, but it is impossible to separate the females from those of Pa. cratifer (Fairchild & Hertig); for that reason, we present below undetermined females of these species, as Pa. cratifer also has been collected in Chiapas, despite the fact that, in this work, we did not find males. Female feeding habits are not known but they are not anthropophilous.
