Description.

Female body length: 3.29 mm (n=1). Color of head: yellow throughout. 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: dorsoventrally strigose throughout. Sculpture of posterior vertex: moderately punctate, rugose posterior to eyes and posterior ocellus. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: dorsoventrally strigose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: variably yellow to brown. Sculpture along posterior pronotal sulcus: striate, striae short and poorly defined. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow. Sculpture of medial mesoscutum: moderately punctate in posterior half, becoming denser anteriorly. Sculpture of mesoscutellum: smooth medially, sparsely punctate laterally. Postacetabular sulcus: comprised of small cells. 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 triangle: sparse. Sculpture of metapleural triangle: punctate rugose. Posterior margin of metapleuron below propodeal spiracle: with blunt kink near intersection with metapleural sulcus. Color of legs: yellow throughout.

Color of metasoma in female: T1, S1, medial T2-T6 brown, otherwise yellow. 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: 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: longitudinally striate. Macrosculpture of lateral T3 in female: longitudinally striate. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: longitudinally strigose. Punctation of T4 in female: absent along midline, otherwise moderately dense. Macrosculpture of T5 in female: punctate rugulose laterally. Punctation of T5 in female: absent along midline, otherwise moderately dense. 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: punctate rugulose. Sculpture of S2: longitudinally strigose medially, otherwise smooth with sparse fine punctation. 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 throughout. Color of hind wing: slightly infuscate 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 warreni is similar to Trichoteleia rugifrons and Trichoteleia solocis with which it shares striae or rugulae on lateral T4-T5 that span the length of the tergites. The frons below the median ocellus in Trichoteleia warreni is evenly dorsoventrally strigose (Fig. 291), whereas in Trichoteleia rugifrons and Trichoteleia solocis , the dorsoventral rugae attenuate or are absent medially (Figs 243, 237).

Etymology.

Trichoteleia warreni is named for Warren Steiner of the US National Museum of Natural History for collection of the holotype specimen of this species, and for the contribution of many other specimens treated in this revision.
