De Marmels (2004) described the larva. Bota-Sierra (2014) reported H. bariai from Colombia ( Meta Department ) based on three males and one female. Here we report H. bariai from Amazonas, Caquetá , Guaviare and Vaupés Departments. The males of this species are small (abdomen around 35 mm ) with color pattern similar to H. falvidorsum , H. bickorum and H. mitratum mitratum . They differ from H. flavidorsum and H. m. mitratum because these two do not present ventrobasal convexity on cerci in mediodorsal view ( Figs. 9H , 10H ), and from H. bickorum by the distance between bifurcation of medial process and tip of cerci close to one third the length of cerci in H. bariai ( Fig. 7G ), but close to half that distance in H. bickorum ( Fig. 8A ). Females are also small (abdomen around 31mm ) and very similar in color pattern to H. breweri ; they differ by the shape of basal teeth of valves in ventral view, rectangular in H. breweri ( Fig. 13E ), but rounded in H. bariai ( Fig. 12H ).
