Description.

Male body length: 3.64 mm (n=1). Color of head: dark brown to black. Central keel of frons: present, extending onto interantennal process. Sculpture of m edial frons in male: smooth. Number of mandibular teeth: three. Basal node on mandible: present. Sculpture of frons below median ocellus: punctate rugulose 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 male: dark brown to black. 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 medially, moderately punctate laterally. Postacetabular sulcus: comprised of small cells. Mesopleural carina: present only in anterior half. Sculpture along ventral half of prespecular sulcus: punctate. 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: coxae and trochanters yellow, otherwise brown.

Color of metasoma in male: dark brown to black throughout. 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. Macrosculpture of T2 in male: longitudinally striate throughout. Macrosculpture of medial T3 in male: longitudinally striate. Macrosculpture of lateral T3 in male: longitudinally striate. Macrosculpture of T4 in male: longitudinally strigose laterally. Punctation of T4 in male: absent along midline, otherwise moderately dense throughout. Macrosculpture of T5 in male: absent. Punctation of T5 in male: absent along midline, otherwise moderately dense throughout. 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 male: 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 takariva is most similar to males of Trichoteleia orona . Trichoteleia takariva lacks a dorsal flange on the interantennal process (Fig. 264) and has moderately dense punctation on T5 (Fig. 265), whereas in Trichoteleia orona the flange is present (Fig. 187) and the punctation of T5 is dense (Fig. 40).

Etymology.

The epithet takariva means “nightfall” in Malagasy. It is applied to this species because of its black color and dusky wings. The epithet is a noun in apposition.
