Description.

Female body length: 4.80 mm (n=1). Color of head: reddish brown. 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: absent. Sculpture of frons below median ocellus: finely punctate throughout. Sculpture of posterior vertex: finely punctate. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: dorsoventrally strigose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: reddish brown throughout. Sculpture along posterior pronotal sulcus: striate, striae well 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 with sparse fine punctures throughout. Postacetabular sulcus: present as a smooth furrow. Mesopleural carina: present only in anterior half. Sculpture along ventral half of prespecular sulcus: punctate rugose. Sculpture of posterolateral mesepisternum: 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: sparse. Sculpture of metapleural triangle: densely punctate. Posterior margin of metapleuron below propodeal spiracle: with blunt kink near intersection with metapleural sulcus. Color of legs: fore and mid coxa white, hind coxa and femur brown, trochanters white, legs otherwise yellow.

Color of metasoma in female: 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: longitudinally strigose throughout. Macrosculpture of medial T3 in female: rugulose. Macrosculpture of lateral T3 in female: longitudinally strigose. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: absent. Punctation of T4 in female: sparse along midline, otherwise dense. Macrosculpture of T5 in female: absent. Punctation of T5 in female: dense through out. Shape of T5 in female: width of posterior margin less than length. Sculpture of T6 in female: densely and finely punctate. Sculpture of S2: densely punctate, punctures of moderate size. 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 with metallic purple sheen. 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 longiventris , Trichoteleia quazii and Trichoteleia carinata are elongate species that have dark to moderate infuscation throughout the forewing and darkly pigmented Rs+M and M+Cu veins. Trichoteleia quazii and Trichoteleia carinata differ from Trichoteleia longiventris by having a longitudinal median carina on S2 (Fig. 45).

Etymology.

Trichoteleia longiventris is named for its extremely long metasoma. The epithet is a noun in apposition.
