Thagria multispinosa Fan & Dai sp. nov.

( Figs. 153–163 )

Description. Body length of male 9.1 mm, female unknown.

Body large, robust ( Fig. 153 ). Crown yellow, with T-shaped brown bands, coronal suture deep brown; ocelli and eyes brown ( Fig. 155 ). Face yellow to light brown ( Fig. 156 ). Pronotum brown, densely covered with light brown nubs ( Fig. 155 ). Mesonotum yellow, central area with one dark brown triangular patch ( Fig. 155 ). Forewing yellowish brown with two pairs of black markings distally ( Figs. 153, 154 ).

Head rounded anteriorly, crown distal length anterad of eyes about 1/4 of entire midlength, coronal suture evident, about 2/3 of midline, disk depressed ( Fig. 155 ). Face with clypeus base broad, apical half contracted, numerous short transverse streaks on each side; clypellus short, base narrower than apex of clypeus, approximately parallel-sided, inflated medially and longitudinally ( Fig. 156 ). Crown, pronotum and mesonotum median length ratio about 1:1:1.6 ( Fig. 155 ).

Male genitalia. Pygofer in lateral view with large, broad caudoventral lobe, caudodorsal margin with paired processes expanded subapically ( Fig. 157 ). Segment X without process. Subgenital plate long and narrow, with tuft of fine long setae distally ( Fig. 158 ). Dorsal connective in dorsal view annular, stem short, rami thin, long, middle parallel, distally attached to base of segment X ( Fig. 159 ). Aedeagus in dorsal view symmetrical, long, base broad, tapered to pointed apically, exceeding midlength of paraphysis, in lateral view curved dorsad apically ( Figs. 160, 161 ); paraphysis in dorsal view symmetrical, long triangular, base broad, narrowed to apical 2/3, end pointed, in lateral view straight and apex curved dorsad ( Figs. 160, 161 ). Style slender, longer than paraphysis, subapex bifid, serrate dorsally and ventrally ( Figs. 160, 162, 163 ).

Type material. Holotype: ♂, CHINA: Guangxi, Damingshan, Alt. 800–1300 m, 5–10 Aug. 2011, coll. Yang Zaihua ( GUGC).

Etymology. The new species name is a combination of the prefix “ multi -” meaning many and “ spinosa ”, referring to the many teeth on the apex of the style.

Remarks. This new species can be separated from other members in this genus by the long, broad pygofer ( Fig. 157 ) and style longer than the paraphysis with numerous serrations apically ( Figs. 160, 162, 163 ).
