Diagnosis. Stridulatory file sinuous ( Fig. 13A–B ). Cerci long, conical, curving inwards from base to beginning of apical portion ( Fig. 11I –K ); inner margin of apical portion with numerous curved spines arranged in a row ( Fig. 11I –K ). Styli short, slender, dorso-ventrally flattened, parallel from the base to median portion and curved inward at the apex ( Fig. 11I –K ). Styli half the length of cerci ( Fig. 11J–K ).
