Tipula (Vestiplex) jiangi Yang & Yang, 1991: 253 View in CoL .

Diagnosis. The species is general yellowish-brown in coloration. Head is yellowish-brown with a brown occipital stripe. Prescutum is grayish-brown, heavily pruinose, with four brown stripes. Wings are grayish-brown with cells c and sc darker than ground color. Abdominal tergites one to four are yellowish-brown with darker stripes medially and laterally, tergites five to eight are wholly dark brown. Tergite nine is separated medially into two parts, with a pair of angular arms ventrally. Gonocoxite is elongate, widened basally and gradually narrowed to apex forming a horn directed dorsally.

Description. Male body length 16.0 mm, wing 18.4mm, antenna 3.5 mm.

Head. Rostrum yellowish-brown with nasus slightly darker. Antennae with scape elongated, yellowish, slightly expanded apically; pedicel very short, pot-shaped, yellowish; flagellum with basal two segments yellow, the rest segments yellowish-gray, with slightly enlarged base dark brown, each flagellomere with black verticils distinctly longer than the flagellomeres from which they arise. Palpi brown. Head yellowish -brown, occipital stripe brown, gradually narrowed to apex, the point extending to the base of vertical tubercle ( Fig. 54 View Figures 54–60 ).

Thorax. Pronotum grayish-brown, with a narrowed yellow area on anterior margin. Prescutum grayish-brown, heavily pruinose, with four brown stripes, all stripes with darker margins ( Fig. 55 View Figures 54–60 ). The median stripe broadened apically and gradually narrowed to base, the lateral stripes long-oval ( Fig. 55 View Figures 54–60 ). Scutum grayish-brown, heavily pruinose, lobes with a dark brown spots ( Fig. 55 View Figures 54–60 ). Scutellum grayish-brown, pruinose, median area paler ( Fig. 55 View Figures 54–60 ). Postnotum grayish-brown, heavily pruinose ( Fig. 55 View Figures 54–60 ). Pleura grayish-brown, anepisternum, katepisternum and meron distinctly pruinose ( Fig. 56 View Figures 54–60 ). Halteres with stem yellowish-brown, knob dark brown. Legs with coxae and trochanters yellow; femora yellowish-brown with dark brown apex; tibiae and tarsi dark brown. Wing with ground color grayish-brown, cells c and sc darker than ground color, stigma dark brown, Rs tinged with dark brown at both ends, apex of wing tinged with light brown including bases of cells r 1+2, r 3, r 4+5, m, cu, the bases of cells m and cu tinged with light brown ( Fig. 57 View Figures 54–60 ). Rs relatively long, slightly shorter than R 3, R 1+2 entire, discal cell relatively broad, petiole of cell m 1 distinctly shorter than discal cell ( Fig. 57 View Figures 54–60 ).

Abdomen. Abdominal tergites one to four yellowish-brown with median and lateral stripes, tergites five to eight wholly dark brown ( Fig. 58 View Figures 54–60 ). Sternites one to four yellowish-brown without stripes, sternites five to eight wholly dark brown. Hypopygium dark brown ( Figs 58–59 View Figures 54–60 ). Gonocoxite elongate, separated from sternite nine, widened basally and gradually narrowed to apex forming a horn directed dorsally ( Figs 60–62 View Figures 54–60 View Figures 61–66 ). Tergite nine separated medially, a pair of angular arms arising from ventral surface of tergite nine ( Fig. 61 View Figures 61–66 ). Sternite nine with a median prominence, on each side of which with a pair of finger-like processes ( Fig. 62 View Figures 61–66 ). Outer gonostylus simple, long lobes ( Figs 60–62 View Figures 54–60 View Figures 61–66 ). Inner gonostylus with two beaks and a transverse ridge medially, dorsal angle rounded in outer lateral view, with a transparent angular lobe on inner side in dorsal view ( Figs 60–64 View Figures 54–60 View Figures 61–66 ).

Semen pump with compressor apodeme V-shaped, each arm expanded apically ( Fig. 66 View Figures 61–66 ). Posterior immovable apodeme straight, narrowed to apex, subequal in length to compressor apodeme ( Fig. 65 View Figures 61–66 ). Anterior immovable apodeme with arms broad ( Fig. 65 View Figures 61–66 ). Aedeagus slender, at least 2.5 times longer than semen pump ( Fig. 65 View Figures 61–66 ).
