Acanthagrion peruvianum Leonard, 1977 (Odonata Coenagrionidae) a junior subjective synonym of A. floridense Fraser, 1946 and description of its final stadium larva

Abstract

Acanthagrion peruvianum Leonard, 1977 is considered a junior subjective synonym of A. floridense Fraser, 1946 based on the analysis of type material. The species is diagnosed and SEM images are provided for male and female diagnostic characters. The larva of A. floridense is described based on specimens collected in Salta, Jujuy and Tucumán provinces (Argentina). A distribution map is given showing that this species is recorded for the first time for Misiones and San Luis provinces in Argentina, and for La Paz and Tarija departments in Bolivia.
