Vein Rs as long as distance between basal end of vein Rs and apical end of vein sc-r. Male: genitalia yellow in ground color, gonocoxal projection brown, gonocoxal lobe and surrounding parts brown, basal portion of aedeagus yellow. S 9 narrow, less than 1 / 10 as wide as long, visible as seam between gonocoxites 9, without sternal projections. Gonocoxite ( Fig. 14 View FIGURE 14 c, d: gc) with gonocoxal lobe ( Fig. 14 View FIGURE 14 c, d: gl) with 2 dentations at apical margin. Gonostylus ( Fig. 14 View FIGURE 14 c: gs) slender, apical 1 / 4 less than 1.5 times as wide as base. Aedeagus ( Fig. 14 View FIGURE 14 c, d) dilated at apical half, without projections. Sclerotized part of aedeagus ( Fig. 14 View FIGURE 14 c: sa) tapered to apex, with slender, angled lateral extension. Female unknown.

Specimens examined. Holotype. Male. “(FENCHIHU)/ Chiayi – Hsien,/ FORMOSA / August 23 rd, 1968 / Coll. M. Nishikawa”, green disk label, “Ne. 4007 ” ( EUMJ).

Etymology. The specific epithet is derived from Latin and refers to the gonocoxal lobe being dentate (denticulatus) at the apex ( Fig. 14 View FIGURE 14 c).
