Head in frontal view 1.53 × as long as wide (Fig. 8 B View Figures 8 ), eyes height 2.75 × malar space, clypeus smooth, anterior margin of clypeus with three asymmetrical teeth, mandible four teeth. Antennae inserted above level of ventral edge of eyes, formula 11263, scape 0.95 × as long as eye height, length of flagellum and pedicel combined longer than head width (1.2 ×), anterior four funicular segments 1.63 × as long as broad, the last two funicular segments 1.15 × as long as broad, clava with micropilosity area at the ventral of last two segments (Fig. 8 E View Figures 8 ), and slightly shorter than last two funicular segments. Head in dorsal view (Fig. 8 D View Figures 8 ), POL 1.45 × OOL. Head in lateral view (Fig. 8 C View Figures 8 ), malar sulcus not distinct, malar space 0.36 × eyes height.

Pronotum covered with large reticulates (Fig. 8 F View Figures 8 ), mesoscutum convex, 2.05 × as broad as long, notauli complete but shallow, scutellum 1.33 as broad as long, frenal line not distinct, reticulations on scutellum smaller than mesoscutum, frenum smooth without reticulates. Propodeum as long as scutellum, median carina and plica not distinct, each side of the upper margin with elliptical depression, callus covered with white dense setae. Forewing with 2–3 rows hairs on the end of costal cell (Fig. 8 G View Figures 8 ), 4 rows of setae in the basal cell, speculum oval and closed below, marginal vein as long as postmarginal vein, 2 × as long as stigmal vein.

Etymology.

‘ splendens ’ means luminous, emphasizing its distinctive bright-green body color among the species in the genus.

Diagnosis.

By comparing the morphology with the seven species of this genus that have been described in the world ( Heydon 1995), it was found that the new species is most similar to T. cyzicu , but the body color of the new species is obviously bright green, while the body color of the latter species is blue-black, the head in frontal view is 1.25 × as long as wide, the propodeum has a complete median carina and plica, and the spiracular sulcus wide and deep.
