ELECTROHEMIPHLEBIA GEN. NOV.

Etymology: The genus-group name is a combination of the Greek term electron (meaning, ‘amber’) and Hemiphlebia , type genus of the family. The name is feminine.

Type species: Electrohemiphlebia barucheli sp. nov.

Diagnosis: Very small damselflies; head not very transverse; clypeofrontal sulcus deep; antefrons with two strong gibbosities separated by a median depression; strong sulcus between frons and vertex (i.e. the plate bearing the ocelli, limited anteriorly by the frons, laterally by the eyes and posteriorly by the occiput); posterior ocelli on a high gibbosity well separated from others and from the vertex and frontal part of frons by complete sulci set inside strong depressions; suture between vertex and occiput rather well pronounced; pterothoracic interpleural suture only present around metastigmal area; protibial comb absent; wings with short petiole; arculus distinctly distal of Ax2; forewing discoidal cell basally opened, with RP + MA, basal part of MA, and MAb aligned or nearly so; angle between MAb and MP + CuA rather acute in forewing discoidal cell; hindwing discoidal cell basally closed; base of RP3/4 close to subnodus; base of IR2 opposite subnodus; subnodus vertical.
