( Figs. 259–268 View FIGURES 259 – 268 )
Description. Body length of male 6.8–7.0 mm, female 7.5–8.0 mm.
Body slender, medium sized ( Fig. 259 View FIGURES 259 – 268 ). Crown ivory yellow; ocelli and eyes brown ( Fig. 261 View FIGURES 259 – 268 ). Face ivory, except distal portion of clypeus and middle of clypellus light brown ( Fig. 262 View FIGURES 259 – 268 ). Pronotum brown, densely covered with light brown nubs ( Fig. 261 View FIGURES 259 – 268 ). Mesonotum yellow, with basal angles brown ( Fig. 261 View FIGURES 259 – 268 ). Forewing brown to black, with transparent patches, venation light brown to dark ( Figs. 259, 260 View FIGURES 259 – 268 ).
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 View FIGURES 259 – 268 ). 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 View FIGURES 259 – 268 ). Crown, pronotum and mesonotum midline ratio about 1:1.2:1.7 ( Fig. 261 View FIGURES 259 – 268 ). Forewing long, apex rounded, appendix narrowed ( Figs. 259, 260 View FIGURES 259 – 268 ).
Male genitalia. Pygofer in lateral view broad, caudodorsal margin with stout process ( Fig. 263 View FIGURES 259 – 268 ). Segment X ventral processes in dorsal view long and concealed ( Fig. 264 View FIGURES 259 – 268 ). Subgenital plate long, and with fine long setae apically ( Fig. 265 View FIGURES 259 – 268 ). 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 View FIGURES 259 – 268 ). Aedeagus symmetrical, extended nearly to apex of paraphysis ( Figs. 266, 267 View FIGURES 259 – 268 ); paraphysis in dorsal view asymmetrical, apex biramous forming two unequal spines, in lateral view slightly twisted dorsally and distally ( Figs. 266, 267 View FIGURES 259 – 268 ). Style not reaching middle of paraphysis ( Figs. 266, 268 View FIGURES 259 – 268 ).

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 View FIGURES 6 – 15 , 259 View FIGURES 259 – 268 ) and the following combination of genitalia features: dorsal connective stem and arm length ratio 1: 3 in T. biprocessa ( Fig. 11 View FIGURES 6 – 15 ), 1:1.8 in T. webbi ( Fig. 264 View FIGURES 259 – 268 ); style ( Fig. 266 View FIGURES 259 – 268 ) not as latter ( Fig. 13 View FIGURES 6 – 15 ), reaching middle of paraphysis, two apical processes of paraphysis ( Figs. 266, 267 View FIGURES 259 – 268 ) also different ( Figs. 13, 14 View FIGURES 6 – 15 ).
