FEMALE GENITALIA ‒ Cerci strongly developed and angled, with wedge-shaped bases projecting toward midline; postgenital lobe somewhat cleft medially; 3 spermathecal capsules, 2 large and one small. MALE GENITALIA ‒ Abdominal tergum IX membranous, without setae; gonocoxite with membranous mesal surface, tergomesal margin not noticeably produced, with many relatively short slender setae; gonostylus irregular in shape, gonostylar claw present; claspette shorter than gonocoxite, with 1 (usually) or 2 short apical spiniform setae; aedeagus broad, more or less oval and rounded distally, lateral plates joined at proximal and distal ends. LARVAE ‒ Head distinctly wider than long; antenna with distal part beyond setae 2,3-A subequal to or shorter than proximal part, distinctly pigmented; setae 2,3-A more or less same length as distal part of antenna; comb with 3‒7 spine-like scales with or without basolateral spicules, sometimes with fringed squamiform scales; ventral brush (seta 4-X) with 3 or 4 pairs of setae on grid and line of precratal setae inserted mid-ventrally on saddle. PUPAE ‒ Apex of trumpet not produced into a heavily sclerotised spine projecting freely from lobe on one side; all or some of setae 1,3,4,6-II‒VII very long; seta 3-II‒VI present, 3-VII absent; seta 11-II‒VII absent; paddle relatively narrow, inner part usually distinctly shorter than outer part.
