Diagnosis. Male and female epiproct strongly developed, approximately a quarter the length of cercus or more in male, distinctly longer than wide in female, and segment 3 of genital ligula with postero-lateral projections, are unique of this genus. Also diagnostic is the combination of an angled frons; rounded postocular lobes; female posterior lobe of pronotum usually not smoothly convex and/or mesanepisternal plates modified; hind femur relatively long, reaching or surpassing anterior margin of S1 when folded against sterna; CuP&AA' absent; antenodal space 1 less than twice the length of 2; internal fold of genital ligula absent; paraproct well developed, not longer than S10 (Pessacq 2008; Garrison et al. 2010).
