Description.

Female body length: 2.83 mm (n=1). Color of head: pale brown, becoming darker at vertex. Central keel of frons: present, extending onto interantennal process. Sculpture of medial frons in female: smooth. Number of mandibular teeth: three. Basal node on mandible: present. Sculpture of frons below median ocellus: punctate rugulose throughout. Sculpture of posterior vertex: punctate rugulose. Occipital rim: comprised of small to miniscule cells. Sculpture of gena: dorsoventrally strigose.

Basiconic sensillum on A7: absent.

Color of mesosoma in female: variably orange to brown. Sculpture along posterior pronotal sulcus: striate, striae well defined. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow. Sculpture of medial mesoscutum: longitudinally rugulose posteriorly, transversely rugulose anteriorly. Sculpture of mesoscutellum: smooth medially, coarsely punctate laterally. Postacetabular sulcus: present as a smooth furrow. Mesopleural carina: present. Sculpture along ventral half of prespecular sulcus: punctate rugose. Sculpture of posterolateral mesepisternum: smooth. Sculpture of ventral surface of mesepisternum: smooth. Setation of ventral metapleural area: absent. Setation of metapleural tr iangle: sparse. Sculpture of metapleural triangle: rugulose. Posterior margin of metapleuron below propodeal spiracle: with blunt kink near intersection with metapleural sulcus. Color of legs: coxae and trochanters yellow, otherwise pale brown, hindlegs the darkest.

Color of metasoma in female: yellow, posterior corners of T2-T4 dark brown. Posterior margin of transverse sulcus on T2: strongly convex. Sublateral tergal carina on T2: absent. Microsculpture on T2: absent. Microsculpture on T3: absent. Microsculpture on T4: absent. Horn on T1 in female: present as a large, apically rounded protuberance. Macrosculpture of T2 in female: longitudinally striate throughout. Macrosculpture of medial T3 in female: absent. Macrosculpture of lateral T3 in female: weakly longitudinally striate. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: obliquely strigose. Punctation of T4 in female: sparse in medial third, moderately dense laterally. Macrosculpture of T5 in female: absent. Punctation of T5 in female: sparse in medial third, moderately dense laterally. 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: smooth with fine setigerous punctures along lateral margin. Sculpture of S2: longitudinally striate anteriorly, smooth posteriorly. Prominent longitudinal median carina on S2: absent.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in female: infuscate in apical two-thirds, white spot near apex, two white patches medially at anterior and posterior margins. Color of hind wing: hyaline throughout. 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.

Trichoteleia picturata is similar to Trichoteleia cincta , Trichoteleia delilah , and Trichoteleia zuparkoi and shares with them the pattern of coloration on the forewings. It can be separated from Trichoteleia cincta by the punctate rugulose sculpture below the median ocellus (Fig. 208), from Trichoteleia delilah by the absence of a basiconic sensillum on A7, and from Trichoteleia zuparkoi by longitudinally rugulose sculpture in the posterior half of the medial mesoscutum (Fig. 207).

Etymology.

The adjectival epithet picturata, meaning “painted”, refers to the color pattern of the forewing in this species.
