Body length: 1.80 mm ( holotype ). Black; A1–A2 yellow; A3–A10 brown; mandible yellow with apex brown; fore and mid legs yellow; hind leg yellow, except tibial apex and tarsi brown; hind coxa brown; fore wing infuscate. Head, in dorsal view, 2.1 times as wide as long; EH <IOS; interocellar area finely coriaceous making weakly transverse striae; OOL <LOL; antenna clava 3-segmented; A1 not reaching vertex dorsal margin; A2–A4, A10 longer than wide; A5–A6, A8 as long as wide; A7–A9 wider than long; base of mandible smooth; frons above torulus with four transverse striae and coriaceous sculpture; interantennal process with reticulate striae, surpassing ventral border of torulus; clypeus exposed; clypeal margin truncate; gena smooth; anterior region of vertex with faint, transverse, slightly curved striae; lateral region of vertex between posterior ocellus and hyperoccipital carina coriaceous, with 3–4 transverse striae reaching external margin of posterior ocellus; lateral region of vertex between hyperoccipital carina and occipital carina coriaceous but without striae; temple projection absent; hyperoccipital carina almost complete: in dorsal view, hyperoccipital carina surpassing level of imaginary line connecting eye inner margin to posterior cephalic margin; distance between posterior ocellus and hyperoccipital carina longer than posterior ocellus diameter. Mesosoma slightly arched; antero-admedian line present; notaulus anteriorly incomplete; lateral notaular area with coriaceous sculpture along its anterior margin; inter-notaular area coriaceous in its basal 1/3 and smooth in its posterior 2/3; 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 subtriangular; mesopleural carina incomplete (length of mesopleural carina/length of mesopleuron = 0.26); fore wing slightly surpassing apex of metasoma. Metasoma elongate; combined length of T3–T6 <T2; T1 shorter than wide; T2 longer than wide; T3–T6 wider than long; anteromedial area of T2 smooth and flattened; T3 densely covered by shallow punctuation; T4–T6 densely covered by deep punctuation; T6 subtriangular. Male . Body length: 1.90 mm (allotype); 1.80 mm ( paratype ); mean length ± SD = 1.85 ± 0.07 mm . Similar to female except the following: hind leg yellow except tibial apex and tarsi dark brown; antenna filiform; A1–A3 yellow; A4–A10 brown; A3 as long as wide; A5–A9 longer than wide; T1 shorter than wide; T3 smooth along its posterior margin and T4–T6 covered by deeply and dense punctuation. Etymology . Named after the country of the type locality. Diagnosis . Both Trichacis panamana and T. mexicana have: T1 shorter than wide; clypeus exposed, and clypeal margin truncate. However, T. panamana has EH <IOS, OOL <LOL and distance between posterior ocellus and hyperoccipital carina longer than posterior ocellus diameter. Material examined.
