Description. Female. Body color: whitish yellow, with antenna dark brownish yellow as scape, pedicel, propleuron, pronotum dorsal and dorso – anterior lateral areas, mesepimeron dorsal area, metapleura dorsal 1/2, hind coxae external area (with irregular shape); mesonotum (except distal area honey yellow) black as head dorsal area (with ocular whitish yellow ring present), propodeum, metasomal terga. Fore wing: M+CU distal 1/2 brownish yellow, remainder whitish yellow as C+SC+R, 1 – 1A, wing mostly with light yellow color; hind wing: veins brownish yellow, wing hyaline. Body length =?; fore wing length = 5 mm.

Head: not present in type.

Mesosoma: Length of mesosoma in dorsal view/width of mesosoma = 2.82; height of mesosoma = 1.20 mm; propleuron nitid; notauli punctate, from smaller laterally to bigger medially, less defined medially; medial longitudinal pit present, smooth without longitudinal punctate sculpturing; remainder mesonotum nitid; sternauli with closely and denser striate sculpturing as union with prepectal carina, area below with less defined colliculate sculpturing; mesopleuron immaculate except dorso-lateral area with large lineate sculpturing; metapleuron granulate and rugose; propodeum granulate and with areolate-rugulose sculpturing throughout, spiracles subcircular; first lateral areas of propodeum with areolate-rugulose sculpturing less conspicuous than remainder propodeum; medial carina as big as or smaller than 1/3 propodeum length; areola irregular; ventral tubercles present with carinae over them and densely granulate.

Legs: basal lobe of hind tarsal claws elongate and acute at tip.

Wings: fore wing: 3RSa/1RS = 4.38; r = 0.18 mm. hind wing: 1M/r – m = 2.80; m+cu antefurcal to 2RS; 2RS slightly bent to wing base; angle at union of veins 2RS – 2M wide; pterostigma black with apical 1/5 light yellow.

Metasoma: Length of first metasomal tergum/width of first metasomal tergum = 0.76; length of second metasomal tergum/width of second metasomal tergum = 0.91; length of third metasomal tergum/width of third metasomal tergum = 0.40; basal width of first metasomal tergum = 0.38 mm; first metasomal tergum dorso – basal triangular area of first metasomal tergum close without carinae present, medial carina normal; first metasomal tergum lineate sculpturing as second metasomal tergum sculpturing; third metasomal tergum lineate sculpturing finer, closer and less conspicuous than second metasomal tergum sculpturing, reaching third metasomal tergum distal edge; fourth metasomal tergum with fine lineate sculpturing

Males. Similar as females; second metasomal tergum sometimes without semi-circular whitish yellow area present. Body length = 5.33 – 4.10 mm; fore wing length = 4.23 – 3.23 mm; Head height/head length = 1.61 – 1.33; maximum height of compound eye/maximum width of compound eye = 1.42 – 1.41; distance between basal edges of tentorial pits and the basal area of toruli/Maximum width of face measured at dorsal edge of clypeus = 0.98 – 0.97; width of vertex/minimal distance between toruli and the medial ocellus = 2.47 – 2.27; width of oral opening/height of oral opening = 2.0; distance between tentorial pits = 0.20 – 0.14 mm; minimal distance between external edge of tentorial pits and compound eye = 0.08 – 0.06 mm. Antenna, flagellomeres all longer than wide, between 38 – 44; malar space slightly smaller than basal width of mandible; occipital carina present and narrower dorsally, not fused with hypostomal carina, clearly separated; median ocellus as big as lateral ocellus; space between lateral ocellus black; ocell-ocular distance almost ½ Lateral ocellus width. Length of mesosoma in dorsal view/width of mesosoma = 2.64 – 2.50; height of mesosoma = 1.06 – 0.85 mm; length of first metasomal tergum/ width of first metasomal tergum = 1.48 – 1.40; length of second metasomal tergum/width of second metasomal tergum = 1.05 – 0.91; length of third metasomal tergum/width of third metasomal tergum = 0.45; basal width of first metasomal tergum = 0.35 – 0.26 mm; fore wing: 1Cub/RS+Ma = 1.09 – 1.07; 3RSa/1RS = 4.33 – 4.0; pterostigma length/width = 2.0 – 1.56; r = 0.20 – 0.15 mm. hind wing: 1M/r – m = 2.75 – 2.50; 1A/cu – a = 0.89 – 0.85.

Type specimens examined. ANSP, Philadelphia, female type, from Mexico (no more information appeared on the labels).

Specimens collected in Costa Rica. 10 males; Alajuela, San Pedro de la Tigra, Cacao, 200 m. iii – iv/1990, Col. R. Cespedes; (5) Puntarenas, R.F. Golfo Dulce, 24 km W. Piedras Blancas, 200 m. ii/1992; 2 same data except date, vi – viii/1992, xii/1991; (3) Rd. to Rincón, 24 km W. Pan – Amer. hwy, 200 m. iii – v/1989, Col. Hanson & Gauld; San José, Ciudad Colón, 800 m. vi – viii/1990, Col. L. Fournier.

Distribution. The altitudinal distribution of this species is middle low elevations. The type of forest present at site of collecting was tropical moist/wet forest and tropical premontane wet/rain forest. Specimens collected from primary forest with shaded areas, from secondary forest next to a coffee plantation with over story trees, and at mixed cacao plantation.

Comments. Sometimes basal area of second metasomal tergum on males with a semi-circular whitish yellow area; frons and middle leg whitish yellow; first metasomal tergum with distal 1/5 whitish yellow. Similar to T. balteus by the bicolored hind leg and the coxae mostly black or with dark brownish yellow spots present but can be sorted from T. balteus by the angle at union of fore wing veins 2RS – 2M wide, the metasoma totally black or with basal area of second metasomal tergum white and with semi – circle shape and first lateral areas of propodeum with areolate-rugulose and granulate sculpturing present.
