A new species and subspecies of Ardeiphagus

Abstract

This genus was erected for a new form of Ischnocera parasitic on Cochlearius c. cochlearis, collected in Colombia, and has since been collected by the author on two species of herons, Tigrisoma salmoni and T. I. lineatum. The new forms are quite distinct from the genotype, A. cochlearius, are closely related to each other and are, apparently conspecific. In the following descriptions all measurements are in millimeters, and all drawings were prepared by the author. Ardeiphagus salmoni new species.
