MALE GENITALIA – Gonocoxite without scales, basotergal area with well-developed projection or small rounded lobe with apical setae; aedeagus not differentiated, phallosome simple, bottle-like or with 3 apical lobes; claspette absent. LARVAE – Seta 3-C minute, less than 0.10 length of seta 2-C, single or forked; setae 5–7-C multi-branched, less than 0.50 length of head capsule. PUPAE – Trumpet without notch at apical margin; seta 13-CT sometimes present, its alveolus present if seta absent; seta 9-II,III short, seta 9-II–VII long, progressively longer from segment IV to segment VII; paddle with fringe of spicules on outer and inner margins.
