Distribution. From Mexico to Argentina ( Hincks and Dibb 1935, Reyes-Castillo 1973) and Cuba, Grenada, Jamaica, and Trinidad and Tobago ( Arrow 1907, Reyes-Castillo 1973, Ivie & Gillogly 1998, Peck et al. 2002).

Comments. Sometimes confused with P. punctiger , P. interstitialis differs by its smaller size, flattened body, and apex of central tubercle not free. Specimens from Jamaica are larger than the maximum size of 29 mm reported Reyes-Castillo (1973) for French Guiana specimens. Morffe et al. (2009) and Morffe & García (2010, 2011) described new species and a new genus of Hystrignathidae (Nematoda) parasite from P. interstitialis .
