Diagnosis. This genus can be distinguished from other genera of Ophioninae by the following combination of character states: (1) mandible not twisted, barely tapered, with sparsely long hairs, its apex dichotomy of axial symmetric teeth or upper tooth slightly longer than lower one (Figs 3, 4, 6, 7); (2) clypeus strongly convex, its lateral profile of lower margin nearly straight to slightly convex (Figs 3, 4, 6, 7); (3) occipital carina complete dorsally and laterally, its lower margin absent, without joined to oral carina (Figs 4, 5, 7, 8); (4) posterior transverse carina of mesosternum complete (Fig. 13), rarely interrupted in a few Australasian species; (5) tibial spur of fore leg without membranous flange; (6) mid and hind trochanters simple; (7) distal pecten of hind tarsal claws distinctly longer than true apex of claw and other pectens (Figs 11, 12); (8) fore wing without sclerites (Figs 1, 2, 14–16); and (9) hind wing usually with an apparently elongated penultimate hamulus on R 1 (Figs 9, 10) (Townes, 1971; Gauld, 1977; Gauld & Mitchell, 1981).
