Dictyopharina octaprotrusa sp. nov.

( Figs. 3–4 , 10–12 , 19–21 , 28–30 , 35 )

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 ) nearly trapeziform, with ratio of length to width between eyes 1.54:1. Frons ( Fig. 11 ) broad and elongate, with ratio of length to width 2.40:1.

Pronotum ( Fig. 10 ) with posterior margin angulately concave at about 110°. Mesonotum ( Fig. 10 ) 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 , 28 ) narrow and high in lateral view ( Fig. 20 ), 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 ) margin slightly excavated, dorsal lateral margin not angular; in ventral view ( Fig. 28 ) dorsal margin slightly concave, lateral ones nearly parallel. Anal tube ( Figs. 20–21 ) large and long in dorsal view ( Fig. 21 ), ratio of length to width at middle about 2.5: 1; in lateral view ( Fig. 20 ) anal tube triangle, narrow and long. Anal style ( Figs. 20–21 ) narrow and long. Paramere ( Figs. 20 , 28 ) large and broad in lateral view ( Fig. 20 ), apex expanded and broad with a stout, inward toothed process; middle with a stout, ventrad directed process. Aedeagus ( Figs. 29–30 , 35 ) 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 ); second pair relatively stout and short, produced dorsad in lateral view ( Fig. 35 ); third pair relatively stout and long, produced ventrad in lateral view ( Fig. 35 ), apex with numerous short setae; fourth pair stout and long, produced laterad in dorsal and ventral views ( Figs. 29–30 ); 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 ), the pygofer without the process ( Fig. 20 ), and the apex of paramere with one toothed process ( Fig. 20 ).

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).
