Male genitalia ( Fig. 8 ). Uncus bell-shaped. Apical process of gnathos clubbed, 1.2 times length of uncus, hooked at apex. Transtilla n-shaped on anterior margin, with three short processes at middle and lateral sides of posterior margin. Valva broad in basal half, apical half about 1/2 width of basal half, apex rounded, densely setose in apical 2/5; costa slightly sinuate, triangularly protruded at basal 1/3, humped at basal 2/3; clasper well developed, presented as a smooth sclerite extending from basal 1/3 of costa to end of sacculus, then angled and outwardly stretched to apical 1/6 of valva along ventral margin, with a lobate, setose process at base; sacculus stout, clubbed, 3/5 length of valva, rounded-triangularly protruded near end. Vinculum 1.8 times as long as wide. Lateral lobes of juxta stout, with globular, setose apex. Aedeagus slender, about same length of valva; cornuti consisted of a twist sclerotized crimple at base, and three or four clusters of spinule distally. Culcita one pair.

Female genitalia ( Fig. 11 ). Ostium at center of seventh segment, surrounded sections strongly sclerotized in flabellate shape. Antrum semicircular. Ductus bursae slightly broader, membranous, twist in anterior 1/3 slightly; narrowed, strongly sclerotized in posterior 2/3, with two slender lateral thorns at posterior margin in V shape. Corpus bursae elongate, oval, slightly longer than ductus bursae, crimpled at junction with ductus bursae. Signa about 10 flag-shaped sclerites located at sclerotized ovate plates, obliquely arranged in posterior 2/5 of corpus bursae.
