Head, in dorsal view, 2.2 times as wide as long; EH <IOS; interocellar area smooth; OOL> LOL; antennal clava 4-segmented; A1 not reaching vertex dorsal margin; A2–A4, A6, A10 longer than wide; A5, A7–A9 as long as wide; base of mandible smooth; frons above torulus with transverse striae; interantennal process reaching, but not surpassing, ventral border of torulus; clypeus exposed; clypeal margin truncate; gena striate; vertex with scattered punctures laterally; temple projection absent; hyperoccipital carina absent; length between posterior ocellus and occipital carina line> OOL. Mesosoma arched; antero-admedian line present; notaulus anteriorly incomplete; lateral notaular area smooth; inter-notaular area with anterior 1/3 coriaceous; posteromedial region of inter-notaular area convex; parapsidal line present; central pronotal area smooth; specialized area of mesoscutellum heart-shaped; median projection of specialized area of mesoscutellum rectangular; mesopleural carina incomplete (length of mesopleural carina/length of mesopleuron = 0.50); fore wing distinctly surpassing apex of metasoma. Metasoma elongate; combined length of T3–T6 <T2; T1 shorter than wide; anteromedial area of T2 smooth and flattened; T2 longer than wide; T3–T5 densely covered by deep punctuation; T6 densely covered by deep punctuation along its anterior border. Male: Unknown. Etymology. The name refers to the punctures present on vertex. Diagnosis . Trichacis punctata and T. acarinata are characterized by the absence of hyperoccipital carina. T. punctata can be distinguished by the combination of the following characters: combined length of T3–T6 <T2; posteromedial region of inter-notaular area convex; fore wing distinctly surpassing apex of metasoma.
