(Figs. 259–268)
Description. Body length of male 6.8–7.0 mm, female 7.5–8.0 mm.
Body slender, medium sized (Fig. 259). Crown ivory yellow; ocelli and eyes brown (Fig. 261). Face ivory, except distal portion of clypeus and middle of clypellus light brown (Fig. 262). Pronotum brown, densely covered with light brown nubs (Fig. 261). Mesonotum yellow, with basal angles brown (Fig. 261). Forewing brown to black, with transparent patches, venation light brown to dark (Figs. 259, 260).
Head with rounded anterior margin, crown wider than eye width, produced about 1/3 of entire median length anterad of eyes, coronal suture evident, about 2/3 of crown midline, disk slightly elevated (Fig. 261). Face with clypeus long, lateral margins slightly convex; clypellus short, base broad, inflated, as wide as clypeus at juncture of clypeal suture, distally constricted, apex truncate (Fig. 262). Crown, pronotum and mesonotum midline ratio about 1:1.2:1.7 (Fig. 261). Forewing long, apex rounded, appendix narrowed (Figs. 259, 260).
Male genitalia. Pygofer in lateral view broad, caudodorsal margin with stout process (Fig. 263). Segment X ventral processes in dorsal view long and concealed (Fig. 264). Subgenital plate long, and with fine long setae apically (Fig. 265). Dorsal connective in dorsal view Y-shaped, stem shorter than rami, distally attaching to the base of processes of segment X by membrane (Fig. 264). Aedeagus symmetrical, extended nearly to apex of paraphysis (Figs. 266, 267); paraphysis in dorsal view asymmetrical, apex biramous forming two unequal spines, in lateral view slightly twisted dorsally and distally (Figs. 266, 267). Style not reaching middle of paraphysis (Figs. 266, 268).
Type material. Holotype: 1♂, CHINA: Guizhou, Kuankuoshui, Xiasi, 13 Aug. 2010, coll. Yu Xiaofei (GUGC). Paratypes: 1♂, CHINA: Hunan, Zhangjiajie, 9 Aug. 2001, coll. Chen Xiangsheng; 1♂, same data as holotype; 1♀, CHINA: Guangxi, Damingshan, 5–10 Aug. 2011, coll. Yang Zaihua; 3♂ 6♀, CHINA: Guizhou, Fanjingshan, 21 Sep. 2011, coll. Long Jiankun, Zheng Weibin, Huang Rong & Fan Zhihua (GUGC). 1♀, CHINA: Hunan, Zhangjiajie, 9 Aug. 2001, coll. Chen Xiangsheng; 1♂, CHINA: Guizhou, Fanjingshan, 21 Sep. 2011, coll. Huang Rong (BMNH).
Etymology. This new species is named for Mr. Webb M.D., Natural History Museum, London, UK.
Remarks. This species is similar to T. biprocessa Fan & Dai, sp. nov., but can be separated by the color pattern of the forewing (Figs. 6, 259) and the following combination of genitalia features: dorsal connective stem and arm length ratio 1: 3 in T. biprocessa (Fig. 11), 1:1.8 in T. webbi (Fig. 264); style (Fig. 266) not as latter (Fig. 13), reaching middle of paraphysis, two apical processes of paraphysis (Figs. 266, 267) also different (Figs. 13, 14).
