( Figs. 5–6 View FIGURES 1–6 , 13–15 View FIGURES 7–15 , 22–24 View FIGURES 16–24 , 31–33 View FIGURES 25–33 , 36 View FIGURES 34–36 )

Description

♂, length (from apex of cephalic process to tip of forewings) 12.1–12.3mm; length of head 1.4–1.5mm, width (including eyes) 1.6–1.7mm; length of forewings 9.8–10.2mm; ♀, length (from apex of cephalic process to tip of forewings) 13.5–13.7mm; length of head 1.5–1.6mm, width (including eyes) 1.7–1.8mm; length of forewings 11.0–11.7mm.

Vertex ( Fig. 13 View FIGURES 7–15 ) nearly trapeziform, with ratio of length to width between eyes 1.53:1. Frons ( Fig. 14 View FIGURES 7–15 ) broad and elongate, with ratio of length to width 2.35:1.

Pronotum ( Fig. 13 View FIGURES 7–15 ) with posterior margin angulately concave at about 100°. Mesonotum ( Fig. 13 View FIGURES 7–15 ) tricarinate on disc; lateral carinae somewhat curving anteriorly towards median carina and not forked. Stigma long, with 4–5 cells. Hind tibia with 5 lateral spines, spinal formula 8(1213)(1112).

Male genitalia: pygofer ( Figs. 23–24 View FIGURES 16–24 , 31 View FIGURES 25–33 ) broad and high in lateral view ( Fig. 23 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. 24 View FIGURES 16–24 ) margin slightly excavated, dorsal lateral margin not angular; in ventral view ( Fig. 31 View FIGURES 25–33 ) dorsal margin slightly concave, lateral ones nearly parallel. Anal tube ( Figs. 23–24 View FIGURES 16–24 ) large and long in dorsal view ( Fig. 24 View FIGURES 16–24 ), ratio of length to width at middle about 1.8: 1; in lateral view ( Fig. 23 View FIGURES 16–24 ) anal tube triangle, narrow and long. Anal style ( Figs. 23–24 View FIGURES 16–24 ) narrow and long. Paramere ( Figs. 23 View FIGURES 16–24 , 31 View FIGURES 25–33 ) large and broad in lateral view ( Fig. 23 View FIGURES 16–24 ), apex expanded and broad with a stout, long dorsally directed toothed process; middle with a stout, ventrad directed process; in ventral view ( Fig. 31 View FIGURES 25–33 ) parameres symmetrical, with numerous spiniform setae on outer and inner surfaces. Aedeagus ( Figs. 32–33 View FIGURES 25–33 , 36 View FIGURES 34–36 ) stout and large; phallobase cylindrical, sclerotized, pigmented with 4 pairs of membranous saclike processes; first pair stout and large, produced ventrad in lateral view ( Fig. 36 View FIGURES 34–36 ); second pair relatively small and short, produced posteriorly in lateral view ( Fig. 36 View FIGURES 34–36 ); third pair stout and very long, produced posteriorly in lateral view ( Fig. 36 View FIGURES 34–36 ), apex with numerous short setae; fourth pair stout and short, produced laterad in dorsal and ventral views ( Figs. 32–33 View FIGURES 25–33 ); phalli forked at base, with a pair of parallel slender processes produced posteriorly, pigmented and sclerotized at apex.

Material examined

Holotype ♂, CHINA: Sichuan, Mt. Emei , 550–750m, 6IX1957 (F. X. Zhu) ( IZCAS) . Paratypes, 1♂, CHINA: Sichuan, Mt. Emei , 550–750m, 31VIII1957 (K. R. Huang) ( IZCAS) ; 1♂, CHINA: Sichuan, Mt. Emei , 9IX1943 ( IZCAS) ; 2♀, CHINA: Sichuan, Chengdu, Longchi , 2IX1943 ( IZCAS) .

Etymology This species is named for its occurrence in Sichuan Province of China.

Remarks

The new species can be distinguished from other species in Dictyopharina by the mesonotum without forked carinae ( Fig. 13 View FIGURES 7–15 ), apex of paramere with a stout, long dorsally directed process ( Fig. 23 View FIGURES 16–24 ), and outer surface of paramere with numerous spiniform setae ( Fig. 23 View FIGURES 16–24 , 31 View FIGURES 25–33 ). It can be separated from D. octaprotrusa sp. nov. by the aedeagal structure ( Figs. 32–33 View FIGURES 25–33 , 36 View FIGURES 34–36 ), especially the size and tendency of membranous saclike processes.
