Cerci with distal third narrower than middle part in posterior view; parallel. Pregonite and postgonite both with expanded base and sudden narrowing at apex, which is darker than base only in pregonite. Distiphallus with smooth ventroapical margin, square/oblong apex, sinuous dorsal outline, large membranous dorsoapical swelling and lateroapical expansions.
