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: dorsoventrally strigose throughout; dorsoventrally strigose throughout with coarsely punctate interstices. Sculpture of posterior vertex: concentrically rugose; 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: dark brown to black. 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, sparsely punctate laterally. Postacetabular sulcus: comprised of small cells. Mesopleural carina: present. Sculpture along ventral half of prespecular sulcus: areolate rugose; coarsely punctate. Sculpture of posterolateral mesepisternum: smooth; punctate; smooth except for 1 or 2 rows of fine punctures parallel to mesopleural carina. Sculpture of ventral surface of mesepisternum: finely punctate; smooth. Setation of ventral metapleural area: absent. Setation of metapleural triangle: sparse. Sculpture of metapleural triangle: rugulose; 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, becoming paler distally.

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. Macrosculpture of T2 in female: longitudinally striate throughout. Macrosculpture of medial T3 in female: transversely striate. Macrosculpture of lateral T3 in female: longitudinally strigose; rugulose. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: weakly longitudinally strigose. Punctation of T4 in female: sparse in medial third, moderately dense laterally; absent along midline, otherwise moderately dense. Macrosculpture of T5 in female: weakly rugulose laterally. Punctation of T5 in female: moderately dense throughout; dense throughout; sparse along midline, otherwise dense. Shape of T5 in female: width of posterior margin greater than or equal to length.

Punctation of T5 in male: dense throughout. Sculpture of S2: longitudinally striate anteriorly, smooth posteriorly; longitudinally striate medially, punctate interstitially. Prominent longitudinal median carina on S2: absent.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in female: infuscate throughout. Color of forewing in male: infuscate throughout. Color of hind wing: 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 orona is a large and distinctive species. The females can be identified by the transverse striation of medial T3 alone (Fig. 191). Males are very similar to Trichoteleia takariva and can be reliably separated by the presence of a dorsal flange on the interantennal process (Fig. 187) and a densely punctate T5 (Fig. 40).

Etymology.

The name orona, meaning “nose” in Malagasy, is given to this species, as a noun in apposition, for the dorsal flange on the interantennal process.
