Abstract

Oreiallagma oreas (Ris, 1918) is a recently rediscovered Colombian Andean endemic species, for which the information available is very scarce. It was originally described from a single male. Since 2008, O. oreas has been recorded in new localities but its life history remained unknown. Here we describe and diagnose the species female for the first time and show evidence of female dichromatism in the genus. Also, we present photographs and illustrations of males and females, a distribution map, and information on this species biology, reporting that it breeds on bromeliads as other species in the genus.

Keywords: Andes, bromeliad breeding, Colombian endemic, color polymorphism, damselfly, dragonfly, Zygoptera
