Description.

Female body length: 2.99-3.25 mm (n=5). Male body length: 2.60-3.16 mm (n=19). Color of head: dark brown to black; yellow, becoming darker dorsally; yellow throughout. Central keel of frons: absent; present, ending above interantennal process. Sculpture of medial frons in female: smooth. Sculpture of medial frons in male: smooth. Number of mandibular teeth: three. Basal node on mandible: absent. Sculpture of frons below median ocellus: densely punctate throughout. Sculpture of posterior vertex: densely punctate; moderately punctate medially, densely punctate laterally. Occipital rim: comprised of small to miniscule cells. Sculpture of gena: punctate rugose; dorsoventrally strigose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: dark brown to black; yellow throughout. Color of mesosoma in male: dark brown to black; variably yellow to brown. Sculpture along posterior pronotal sulcus: striate, striae well defined. Notaulus: smooth furrow incomplete, reaching suprahumeral sulcus as row of punctures. Sculpture of medial mesoscutum: moderately punctate in posterior half, becoming denser anteriorly. Sculpture of mesoscutellum: smooth with sparse fine punctures throughout; smooth medially, sparsely punctate laterally. Postacetabular sulcus: comprised of small cells. Mesopleural carina: absent; present. Sculpture along ventral half of prespecular sulcus: punctate. Sculpture of posterolateral mesepisternum: smooth; smooth except for 1 or 2 rows of fine punctures parallel to mesopleural carina. Sculpture of ventral surface of mesepisternum: smooth. Setation of ventral metapleural area: absent. Setation of metapleural triangle: absent; sparse. Sculpture of metapleural triangle: smooth; finely punctate. Posterior margin of metapleuron below propodeal spiracle: straight to moderately convex; with blunt kink near intersection with metapleural sulcus. Color of legs: yellow throughout; pale brown throughout.

Color of metasoma in female: dark brown to black throughout; T1, medial T4 brown, otherwise yellow. Color of metasoma in male: pale to dark brown throughout; dark brown to black throughout. Posterior margin of transverse sulcus on T2: strongly convex. Sublateral tergal carina on T2: absent. Microsculpture on T2: present. Microsculpture on T3: present. Microsculpture on T4: present. Horn on T1 in female: present as a large, apically rounded protuberance. Macrosculpture of T2 in female: weakly longitudinally striate throughout. Macrosculpture of medial T3 in female: absent. Macrosculpture of lateral T3 in female: absent. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: absent. Punctation of T4 in female: sparse in medial third, moderately dense laterally; absent in medial third, sparse laterally. Macrosculpture of T5 in female: absent. Punctation of T5 in female: mo derately dense throughout. Shape of T5 in female: width of posterior margin greater than or equal to length. Microscupture on T6 in female: absent. Sculpture of T6 in female: densely and finely punctate. Macrosculpture of T2 in male: longitudinally striate throughout; weakly longitudinally striate throughout. Macrosculpture of medial T3 in male: absent. Macrosculpture of lateral T3 in male: absent. Macrosculpture of T4 in male: absent. Punctation of T4 in male: sparse in medial third, moderately dense laterally; sparse throughout. Macrosculpture of T5 in male: absent. Punctation of T5 in male: sparse in medial third, dense laterally; sparse in medial third, moderately dense laterally. Sculpture of S2: crenulate along anterior margin, otherwise smooth with small punctures throughout. Prominent longitudinal median carina on S2: absent.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in female: slightly infuscate with longitudinal dark streak. Color of forewing in male: slightly infuscate throughout; slightly infuscate with longitudinal dark streak. Color of hind wing: hyaline throughout; hyaline with faint infuscate patches posterior to R and along anterior margin apical to R. Density of setation in fore wing: uniform throughout. Density of setation in hind wing: uniform throughout. Length of R1: more than 1.5 times as long as r. M+Cu and RS+M in forewing: nebulous.

Diagnosis.

This species is similar to Trichoteleia hemlyae and Trichoteleia ravaka . It can be separated by its lack of a well-developed central keel on the frons (Figs 4, 202) and the smooth to sparsely and finely punctate metapleural triangle (Fig. 199).
