(Figs 1 D, H, L, 4 A–G)
Description. Measurements. Male. Body length (including tegmina): 6.8–7.1 mm. Head width (including eyes): 1.85 mm. Crown length × width: 1.05 × 0.75 mm; eyes width: 0.55 mm; clypeus length: 0.85 mm. Pronotum length × width: 0.65 × 2.05 mm. Scutellum length: 1.0 mm.
External morphology. Male. General color green to light or dark brown with numerous small ivory markings (Fig. 1 D, H). Head light yellow, without spots. Crown yellowish-brown, eyes light to dark brown, ocelli black (Fig. 1 D, H, L). Face uniformly ochraceous brown with 2 transverse color bands (Fig. 1 L). Pronotum and scutellum with irregular shaped brown spot on ivory background medially, apex yellow (Fig. 1 D). Forewing brown, with numerous light fuscous reticulations; venation black, with numerous small ivory markings (Fig. 1 D, H).
Medium sized, slightly robust species (Fig. 1 D). Head anterior margin rounded (Fig. 1 D). Crown broader than eyes width, produced beyond margin of eyes, lateral margins convergent basally, disk similar in level to eyes (Fig. 1 D). Face with clypeus long, broad at basal half, lateral margins constricted near middle, tapered to narrow, truncate apex (Fig. 1 L).
Male genitalia. Pygofer in lateral view with broad, elongate caudoventral lobe, caudodorsal margin with pair of long, curved processes (Fig. 4 A). Segment X with pair of slender processes, processes extending beyond pygofer processes in dorsal view (Fig. 4 B). Dorsal connective broadly U-shaped (Fig. 4 B). Style long, exceeding apex of aedeagal paraphysis, slender, with numerous fine processes from mid-length to subapex (Fig. 4 C). Aedeagus symmetrical, very long, nearly reaching apex of ventral paraphysis; gonopore apical; ventral paraphysis asymmetrical, broad basally, abruptly attenuated at about middle, strongly curved ventrad at apex in lateral view, with a lateral, large and sharp process on subbase (Fig. 4 D–E). Connective Y-shaped, stem short (Fig. 4 F). Subgenital plate relatively broad, tapered to rounded apex, with row of macrosetae distally, marginal setae short and fine (Fig. 4 G).
Female. Unknown.
Host. Unknown.
Material Examined. Holotype: male, China: Anlong county, Guizhou Province, 22. VII. 2016, collected by Din Yongshun. Paratypes: male, China: Tian'e county, Guangxi Province, 19. VII. 2015, collected by Zhan Hongping. No. CTW19003.1–2.
Distribution. China (Guizhou, Guangxi province).
Etymology. The new species name combines the Latin words “ denti -” (tooth) and “ costa ” (side), referring to the lateral tooth-like process on the aedeagal paraphysis.
Remarks. This new species is similar to T. anisota Freytag, 2010 according to the original description, but can be distinguished by the paraphysis with a lateral subbasal, tooth-like process and the unforked segment X and the shape of the style.
