Description.

Female body length: 2.14-2.70 mm (n=9). Male body length: 2.22-2.90 mm (n=20). Color of head: dark brown to black; yellow, becoming darker dorsally; yellow throughout. Central keel of frons: present, extending onto interantennal process. Sculpture of medial frons in female: smooth. Sculpture of medial frons in male: smooth. Number of mandibular teeth: three. Basal node on mandible: present. Sculpture of frons below median ocellus: punctate rugulose throughout; finely punctate throughout, dorsoventrally strigose laterally; moderately punctate throughout. Sculpture of posterior vertex: moderately punctate; moderately punctate, rugose posterior to eyes and posterior ocellus; finely punctate. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: punctate rugose; dorsoventrally strigose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: variably red to black; variably yellow to brown. Color of mesosoma in male: dark brown to black; variably yellow to brown. 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, 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 posterolaterally projecting spine near intersection with metapleural sulcus. Color of legs: yellow throughout; brown throughout.

Color of metasoma in female: yellow to pale brown, posterolateral corners of T2-T3 dark brown. Color of metasoma in male: variably yellow to brown 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. Horn on T1 in female: present as a large, apically rounded protuberance; present as a small bulge. Macrosculpture of T2 in female: longitudinally striate throughout. Macrosculpture of medial T3 in female: weakly longitudinally striate; longitudinally striate. Macrosculpture of lateral T3 in female: longitudinally striate. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: obliquely strigose; weakly obliquely rugulose. Punctation of T4 in female: sparse in medial third, moderately dense laterally. Macrosculpture of T5 in female: absent. Punctation of T5 in female: moderately dense throughout. 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. Macrosculpture of T2 in male: striate anteriorly, with few striae reaching T3. Macrosculpture of medial T3 in male: absent. Macrosculpture of lateral T3 in male: absent; weakly longitudinally striate. Macrosculpture of T4 in male: absent. Punctation of T4 in male: sparse in medial third, moderately dense laterally; sparse throughout; absent in medial third, sparse laterally. Macrosculpture of T5 in male: absent. Punctation of T5 in male: 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 female: slightly infuscate throughout. 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: reduced posterior to Sc+R. Length of R1: more than 1.5 times as long as r. M+Cu and RS+M in forewing: nebulous.

Diagnosis.

Trichoteleia nify may be identified by the presence of a spine along the posterior margin of the metapleuron near the intersection of the margin with the metapleural sulcus (Fig. 29) and the presence of a flange dorsal to the lateral setal patch on T1 (Fig. 29).

Etymology.

This species is given the name nify, a noun in apposition, meaning “tooth” in Malagasy, in reference to its metapleural spine.
