Description of the final-instar of Protoneura tenuis (Selys, 1886) (Odonata: Zygoptera), with comments on reproductive behavior and a comparison of known larvae

Abstract

The final instar of Protoneura tenuis (Selys, 1886) is described and illustrated based on laboratory-reared specimens from the municipality of Magalhães Barata, Pará State, northern Brazil. In addition, notes on the reproductive behavior of adults are provided. The larva of P. tenuis can be distinguished from that of P. paucinervis by the number of spines on the lateral margins of the prementum, the shape of the distal margin of the labial palp, and the form of the nodus of the caudal gills. This is the second larva described for a South American species of the genus.

Keywords. Aquatic insect, Amazonia, damselfly, exuviae, larva
