Revision of the American genus Platyvelia Polhemus & Polhemus, 1993 (Heteroptera: Gerromorpha: Veliidae)

ABSTRACT

ABSTRACT The subfamily Veliinae (Heteroptera Gerromorpha Veliidae) includes ten genera worldwide, seven of which are endemic to the American continent. Here, we provide a revision of Platyvelia Polhemus and Polhemus, 1993, which is distributed from the United States to northern Argentina, and included nine valid species prior to this study. Six species are redescribed, the synonymies of P. egregia (Drake and Harris, 1935) and P. verdica (Drake, 1951) with P. brachialis (Stål, 1860) are proposed, a lectotype is designated for P. annulipes, and two species groups are erected based on male characters the P. annulipes group and the P. brachialis group. Keys to the species groups and species within each group, photos, and distribution maps are also included.
