Vein Rs longer than distance between basal end of vein Rs and apical end of vein sc-r. Male: genitalia yellow in ground color, gonocoxal projection yellow, sternal projection of S 9 black, basal portion of aedeagus yellow. S 9 ( Fig. 14 View FIGURE 14 a: S 9) narrow, 1 / 4 as wide as long, with sternal projection ( Fig. 14 View FIGURE 14 a: sp) keel-like in shape. Gonocoxite ( Fig. 14 View FIGURE 14 a, b: gc) without gonocoxal lobe. Gonostylus ( Fig. 14 View FIGURE 14 a: gs) slender, apical 1 / 4 less than 1.5 times as wide as base. Aedeagus ( Fig. 14 View FIGURE 14 a, b) dilated at apical half, without projections. Sclerotized part of aedeagus ( Fig. 14 View FIGURE 14 a: sa) tapered to apex, with slender, angled lateral extension. Female unknown.
