Abstract

A taxonomic review of the lebiine subtribe Pericalina in the Western Hemisphere, this paper includes a treatment of the genus-groups, a key to the genera, keys to subgenera, species groups, and species of each polybasic genus, descriptions of new species and new subgenera, new locality records for previously described species, re-rankings, and new synonymy. In total, 111 species and subspecies are treated, 26 of which are described as new.

A review of the taxonomically useful mandibular structure, based on stereo-electron (SEM) photographs, requires changes in previously published names of various structures. A review of adhesive vestiture on the front tarsi of males shows 3 different types each characteristic of different taxa.
