Measurements. Length (including forewing): male 3.4–4.1 mm (N = 20), female 3.4–4.5 mm (N = 25).
Coloration. General color grayish yellow to brownish ( Figs 27, 28 View FIGURES 27–39 ). Head ( Figs 27, 29 View FIGURES 27–39 ) grayish white. Vertex ( Figs 27, 29 View FIGURES 27–39 ) with 2 long fuscous stripes along midline from apical third to apex, posterior margin with a brown transverse stripe each sides. Frons ( Fig. 30 View FIGURES 27–39 ) grayish white, with an inverted chevron shaped marking, lateral margins with 2 slender and 1 broad dark brown transverse stripes, middle area white, each side with an oblique dark brown wedge-shaped stripe. Genae ( Fig. 28 View FIGURES 27–39 ) grayish white, with 3 fuscous transverse stripes before eyes (2 above and 1 below ocelli), 1 short transverse stripe dorsad, area beneath antenna with a yellowish brown marking. Eyes fulvous, ocelli reddish-brown. Antennae yellowish brown to brown. Lateral areas of pronotum ( Figs 27, 29 View FIGURES 27–39 ) with 1 brown spots on both sides. Mesonotum ( Figs 27, 29 View FIGURES 27–39 ) with irregular yellowish brown to fuscous markings. Tegula yellowish white to brownish. Forewings ( Fig. 31 View FIGURES 27–39 ) pale brown, many brown to fuscous spots scattered, veins with many white vesicular markings, callus blackish brown, tinged with light red marking. Hindwings ( Fig. 32 View FIGURES 27–39 ) brownish, base of veins brown. Abdomen fuscous, lateral margins brown.
Head and thorax. Head ( Figs 27, 29 View FIGURES 27–39 ) rectangular. Vertex medially longer than wide at base (1.47: 1), disk depressed, with middle carina, lateral carinae strongly keeled. Frons ( Fig. 30 View FIGURES 27–39 ) near rhomboid, longer in midline than wide at widest portion (about 1.32: 1), with a weak median carina, lateral margins strongly foliate. Rostrum with apical as long as subapical segment. Pronotum ( Figs 27, 29 View FIGURES 27–39 ) short, in midline shorter than vertex (0.55: 1), with 3 longitudinal carinae. Mesonotum ( Figs 27, 29 View FIGURES 27–39 ) longer in midline than vertex and pronotum combined (1.73: 1), with 3 carinae. Forewing ( Fig. 31 View FIGURES 27–39 ) slender, longer than maximum width (2.82: 1), CuA 1 obviously convex distad of clavus, not reaching MP. Hindwings ( Fig. 32 View FIGURES 27–39 ) wide, longer than widest part (1.94: 1). Hind tibiae with a lateral spine.
Male genitalia. Pygofer ( Figs 36, 37 View FIGURES 27–39 ) in lateral view, gradually widened from the back to the abdomen, anterior margin strongly concave in the middle, posterior margin distal half obliquely straight, with an obtuse angular process near the middle, medioventral process with a small obtuse process at the apex of dorsal margin; in ventral view, basal margin of pygofer broadly rounded, medioventral process tapering distally, apical margin angular. Anal tube ( Fig. 33 View FIGURES 27–39 ) nearly square in dorsal view, slightly wider at base than apex, apical margin with a wide angular depression medially, anal style long, apical margin rounded and convex, obviously extending out apical margin of anal tube. Aedeagus ( Figs 38, 39 View FIGURES 27–39 ), asymmetrical bilaterally, tubular, membranous, divided into 4 lobes at apex; in ventral view, ventral lobe shorter than dorsal lobe, apical margin angular concave medially, lateral margins serrated, with 7–8 dentate spikes, with a small straight process in the middle toward the base; in dorsal view, right and left dorsal lobes of phallobase separated, apical margins obtuse rounded, each with a row of serrate spines from middle to base, lateral margin of right dorsal lobe with a triangular process medially. Gonostyli ( Figs 34, 35 View FIGURES 27–39 ) bow-shaped, apex rounded and convex; in ventral view, outer margin of distal half with single, large, hornlike process; in dorsal view, distal half of dorsal margin bearing 1 pointed dentate process oriented inward, middle area with 1 twisted broad enlarged process oriented outward, basal side with an obtuse angular process, outer side with a fingerlike process.
Remarks. Chou & Wang (in Chou et al., 1985) described the D. acuminata based on one male specimen from Xinglong, Hainan province, China. In our study we examined topotypic material (20 male specimens) which we identified as D. acuminata based on external morphological characteristics which according to the original description appear completely congruent to those of D. acuminata .
Distribution. China (Hainan) ( Fig. 40 View FIGURE 40 ).
