( Figs 1 View FIGURE 1 A–B, E–F, I–J, 2 A–M)
Description. Measurements. Male. Body length (including tegmina): 7.9 mm. Head width (including eyes): 2.4 mm. Crown length × width: 1.0× 0.70 mm; eyes width: 0.70 mm; clypeus length: 1.35 mm. Pronotum length × width: 0.80 × 2.30 mm. Scutellum length: 1.3 mm. Female. Body length (including tegmina): 7.8 mm. Head width (including eyes): 2.1 mm. Crown length×width: 0.90 × 0.70 mm; eyes width: 0.60 mm; clypeus length: 1.0 mm. Pronotum length × width: 0.80 × 2.1 mm. Scutellum length: 1.3 mm.
External morphology. Male and female. General color pale brown to brown speckled with yellow spots ( Fig. 1 View FIGURE 1 A–B, E–F). Head ochraceous, with dark brown basal spots. Crown yellow with 2 short black stripes medially, eyes and ocelli dark brown ( Fig. 1 View FIGURE 1 A–B, E–F, I–J). Face ochraceous, with black markings ( Fig. 1 View FIGURE 1 I–J). Pronotum dark, with numerous yellow spots. Scutellum brown, with yellow plaque ( Fig. 1 View FIGURE 1 A–B, E–F). Forewing light brown with numerous darker brown markings arranged symmetrically, apical cells fuscous, venation dark brown with inconspicuous yellow spots; male with one median spot on subapex of clavus, one spot on costal margin about 4/5 from base, ochraceous, apical cells fuscous; female with one spot on apex of clavus, two spots on costal margin about 1/3 and 2/3 distance from base, respectively ( Fig. 1 B, F View FIGURE 1 ).
Medium sized, robust species ( Fig. 1 View FIGURE 1 A–B). Head with anterior margin broadly rounded ( Fig. 1 View FIGURE 1 A–B). Crown wide and short, roundly produced beyond anterior margin of eyes, interocular width greater than width of eyes ( Fig. 1 View FIGURE 1 A–B, E–F). Face with clypellus short, not inflated, similar in shape in male and female, constricted in apical half, apex rounded ( Fig. 1 View FIGURE 1 I–J).
Male genitalia. Pygofer caudal margin with three acute processes in lateral view; with pair of apically crossing dorsal processes ( Fig. 2 A View FIGURE 2 ). Segment X process absent. Dorsal connective broadly U-shaped in ventral view ( Fig. 2 B View FIGURE 2 ). Style slender, nearly reaching apex of aedeagal paraphysis, curved and attenuated apically in dorsal view ( Fig. 2 C View FIGURE 2 ). Aedeagus symmetrical, relatively long, distal region extending over distal 2/3 of ventral paraphysis in dorsal view; gonopore apical; ventral paraphysis asymmetrical, gradually narrowed from base to apex, apically tapered, subapex curved in dorsal view ( Fig. 2 View FIGURE 2 D–E). Connective somewhat H-shaped, stem long and broader than arms, with median cleft ( Fig. 2 F View FIGURE 2 ). Subgenital plate relatively broad, with numerous slender setae, marginal setae long and fine ( Fig. 2 G View FIGURE 2 ).
Female genitalia. Valvulae III, in lateral view, with expanded distal region extending over distal 2/3, apex rounded, with fine setae on apical and ventral margins ( Fig. 2 View FIGURE 2 H–I). Valvulae I weakly curved dorsally from base, middle portion narrow, subapex broadened and gradually narrowed to apex, tip acute ( Fig. 2 View FIGURE 2 J–K), sculpture comprising striations, some branched, arranged longitudinally basally and oblique distally. Valvulae II, in lateral view, with blade-like area extending over distal 2/3; dorsal sclerotised and hyaline area present; dorsal margin with distinct fine teeth, teeth bluntly rounded, widely spaced, distributed from beginning of broadened portion to area before apex ( Fig. 2 View FIGURE 2 L–M).
Host. Unknown.
Material Examined. Holotype: male, China: Damingshan , Guangxi Province, 02. V. 2017, Collected by Wang Xianyi . Paratypes: female, same data as holotype. No. CTW19001.1–2.
Distribution. China (Guangxi province).
Etymology. The new species name combines the Latin words “ tri -” (three) and “ furcata ” (forked), referring to the three forked pygofer lobe.
Remarks. This new species is similar to T. biprocessa Fan & Dai, 2015 according to the original description and illustrations, but can be distinguished by the male pygofer lobe with three processes, smooth aedeagal shaft and slender style.
