Description.

Male body length: 3.35-4.05 mm (n=2). Color of head: dark brown to black. Central keel of frons: present, extending onto interantennal process; present, bifurcating ventrally around interantennal process. Sculpture of medial frons in male: smooth. Number of mandibular teeth: three. Basal node on mandible: absent. Sculpture of frons below median ocellus: moderately punctate throughout. Sculpture of posterior vertex: moderately punctate. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: punctate rugose; dorsoventrally strigose.

Color of mesosoma in male: dark brown to black. Sculpture along posterior pronotal sulcus: striate, striae well defined. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow; 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. Postacetabular sulcus: comprised of small cells. Mesopleural carina: absent. Sculpture along ventral half of prespecular sulcus: punctate. Sculpture of posterolateral mesepisternum: punctate. Sculpture of ventral surface of mesepisternum: finely punctate. Setation of ventral metapleural area: absent. Setation of metapleural triangle: sparse. Sculpture of metapleural triangle: punctate rugose. Posterior margin of metapleuron below propodeal spiracle: straight to moderately convex. Color of legs: fore and mid legs yellow to pale brown, hind legs dark brown.

Color of metasoma in male: dark brown to black throughout. Posterior margin of transverse sulcus on T2: straight. Sublateral tergal carina on T2: present. Microsculpture on T2: present. Microsculpture on T3: present. Microsculpture on T4: absent. Macrosculpture of T2 in male: longitudinally striate throughout. Macrosculpture of medial T3 in male: longitudinally strigose. Macrosculpture of lateral T3 in male: longitudinally strigose. Macrosculpture of T4 in male: absent. Punctation of T4 in male: sparse in medial third, moderately dense laterally. Macrosculpture of T5 in male: absent. Punctation of T5 in male: dense throughout; sparse in medial third, dense laterally. Sculpture of S2: densely punctate, punctures of moderate size. Prominent longitudinal median carina on S2: present.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in male: 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 carinata has a distinctly elongate metasoma similar to Trichoteleia longiventris, and it has a longitudinal median carina on S2, as does Trichoteleia quazii (Fig. 45). It can be separated from both of these species by the presence of a prominent longitudinal carina on the lateral part of T2 (Fig. 84).

Etymology.

This species is named for the diagnostic carinae on lateral T2 and medial S2. The epithet is an adjective.
