Head quite hirsute, almost circular, postocular suture scarcely marked, width/length = 0.79; eyes not large OR = 0.60; Md: 3-2 incisor teeth and 2-1 molar teeth. Mm conspicuous, Sm hirsute, anterior margin membranous and basally broad (Fig. 13 ). Forewing length 9.50 mm, hindwing length 7.80. Wing base union type B, wing venation (Fig. 14 ): Ma, Ma1, Ma2, and Mp diffuse but clearly reach wing edge, Cua less conspicuous not reaching wing edge; cross-veins in forewing: R1-Rs: 4, Rs-Ma1: 2, Ma-Mp: 1 o 2, Cu-A: 2 (Fig. 14 ). Basitarsus of hind leg narrow and large (Fig. 15 ): length 0.58, width/length = 0.26, medial bladder large, medial bladder diameter/ basitarsus width = 0.67; single row of setae on retrolateral face, four rows on anterolateral face, two or three rows of setae on ventrobasal face. Terminalia (Figs 16-18 ), anterior margin of 10L slightly concave, inner basal angle of 10L excavate (Fig. 16 ); 10Lp1 not bifid, prolonged, and straight, without longitudinal carina, apex moderately curved (Fig. 17 ); 10Rp1 with apex dorsally acute and ventrally globose (Fig. 18 ); 10Rp2 clearly defined bar (Fig. 16 ). Ep conspicuous. Hp with longitudinal keels (Fig. 18 ), Lpp as Fig. 18 , microtrichia present; Rpp not conspicuous. LC2 clearly longer than LC1, longitudinal ratio of LC1/LC2: 0.65; LC1dp medial, shape as Fig. 16 . Female. Unknown.
