( Figs. 3–4 View FIGURES 1–6 , 10–12 View FIGURES 7–15 , 19–21 View FIGURES 16–24 , 28–30 View FIGURES 25–33 , 35 View FIGURES 34–36 )
Description
♂, length (from apex of cephalic process to tip of forewings) 11.9–15.6mm; length of head 1.6–1.9mm, width (including eyes) 1.5–2.0mm; length of forewings 9.5–12.7mm; ♀, length (from apex of cephalic process to tip of forewings) 13.9–16.7mm; length of head 1.7–2.1mm, width (including eyes) 1.6–2.1mm; length of forewings 10.9–13.4mm.
Vertex ( Fig. 10 View FIGURES 7–15 ) nearly trapeziform, with ratio of length to width between eyes 1.54:1. Frons ( Fig. 11 View FIGURES 7–15 ) broad and elongate, with ratio of length to width 2.40:1.
Pronotum ( Fig. 10 View FIGURES 7–15 ) with posterior margin angulately concave at about 110°. Mesonotum ( Fig. 10 View FIGURES 7–15 ) tricarinate on disc; lateral carinae curving anteriorly towards median carina and forked obscurely at 1/5 to front, outer forks obscure and straight, inner ones longer and stronger. Stigma long, with 5–7 cells. Hind tibia with 6–7 (mostly 6) lateral spines, spinal formula 8(1112)(1112).
Male genitalia: pygofer ( Figs. 20–21 View FIGURES 16–24 , 28 View FIGURES 25–33 ) narrow and high in lateral view ( Fig. 20 View FIGURES 16–24 ), posterior margin straight and curved anteriorly near 1/3 apex to accommodate anal tube, length ratio of upper margin to lower margin about 1:3; in dorsal view dorsal ( Fig. 21 View FIGURES 16–24 ) margin slightly excavated, dorsal lateral margin not angular; in ventral view ( Fig. 28 View FIGURES 25–33 ) dorsal margin slightly concave, lateral ones nearly parallel. Anal tube ( Figs. 20–21 View FIGURES 16–24 ) large and long in dorsal view ( Fig. 21 View FIGURES 16–24 ), ratio of length to width at middle about 2.5: 1; in lateral view ( Fig. 20 View FIGURES 16–24 ) anal tube triangle, narrow and long. Anal style ( Figs. 20–21 View FIGURES 16–24 ) narrow and long. Paramere ( Figs. 20 View FIGURES 16–24 , 28 View FIGURES 25–33 ) large and broad in lateral view ( Fig. 20 View FIGURES 16–24 ), apex expanded and broad with a stout, inward toothed process; middle with a stout, ventrad directed process. Aedeagus ( Figs. 29–30 View FIGURES 25–33 , 35 View FIGURES 34–36 ) stout and large; phallobase cylindrical, sclerotized, pigmented with 4 pairs of membranous saclike processes; first pair narrow and long, produced posteriorly in lateral view ( Fig. 35 View FIGURES 34–36 ); second pair relatively stout and short, produced dorsad in lateral view ( Fig. 35 View FIGURES 34–36 ); third pair relatively stout and long, produced ventrad in lateral view ( Fig. 35 View FIGURES 34–36 ), apex with numerous short setae; fourth pair stout and long, produced laterad in dorsal and ventral views ( Figs. 29–30 View FIGURES 25–33 ); phalli forked at base, with a pair of parallel slender processes produced posteriorly, pigmented and sclerotized at apex.

Etymology This species is named for its 4 pairs of membranous saclike processes on the aedeagus.
35. D. octaprotrusa sp. nov. (♂, holotype). 36. D. sichuanensis sp. nov. (♂, holotype).
Remarks
This species is similar to D. consanguinea Distant, 1906 , from Burma, but can be distinguished from the latter by the vertex whose lateral margins are relatively straight, and the hind tibia with distinct spine on its basal area. The species can be distinguished from D. viridissima Melichar, 1903 , by its elongate head ( Fig. 10 View FIGURES 7–15 ), the pygofer without the process ( Fig. 20 View FIGURES 16–24 ), and the apex of paramere with one toothed process ( Fig. 20 View FIGURES 16–24 ).
The new species possesses the obscure forked carinae on the mesonotum. However, like D. viridissima , in some specimens the forked carinae are too obscure to observe.
Distribution Southern China (Fujian, Guangdong, Guangxi, Hainan, Hunan, Jiangxi).
