Identification

This genus has tridentate and small mandibles, with paraclypeal fovea short, not reaching ventral edge of eyes. Vein cuqu1 (2-SR) present and sclerotized and nervulus (cu-a) postfurcal. It is differentiated from the genus ''Aspilota'' by the short size of the paraclypeal fovea far separated from the inner margin of the eye. Moreover, this genus can be differentiated from the genus ''Synaldis'' Foerster, 1862 by the presence of the vein cuqu1 (2-SR) and ''Adelphenaldis'' Fischer, 2003 by the short size of the paraclypeal fovea and the presence of the vein cuqu1 (2-SR).
