Description.

Female body length: 4.64 mm (n=1). Male body length: 3.53 mm (n=1). Color of head: dark brown to black. Central keel of frons: present, ending above interantennal process. Sculpture of medial frons in female: punctate with irregularly shaped smooth area. Sculpture of medial frons in male: smooth. Number of mandibular teeth: two. Basal node on mandible: present. Sculpture of frons below median ocellus: densely punctate throughout. Sculpture of posterior vertex: densely punctate. Sculpture of gena: punctate rugose. 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: rugulose. Notaulus: smooth furrow incomplete, reaching suprahumeral sulcus as row of punctures. Sculpture of medial mesoscutum: smooth and sparsely punctate posteriorly, densely punctate and transverely rugulose anteriorly. Sculpture of mesoscutellum: smooth with sparse fine punctures throughout. Postacetabular sulcus: comprised of small cells. Mesopleural carina: present. Sculpture along ventral half of prespecular sulcus: coarsely punctate. Sculpture of posterolateral mesepisternum: coarsely punctate. Sculpture of ventral surface of mesepisternum: moderately 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: femora and metacoxa brown, otherwise yellow.

Color of metasoma in female: black. 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: present. Microsculpture on T3: present. Microsculpture on T4: absent. Horn on T1 in female: present as a large, apically rounded protuberance. Macrosculpture of T2 in female: reticulate rugose throughout. Macrosculpture of medial T3 in female: rugulose. Macrosculpture of lateral T3 in female: reticulate rugose. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: longitudinally strigose. Punctation of T4 in female: sparse along midline, otherwise dense. Macrosculpture of T5 in female: longitudinally strigose laterally. Punctation of T5 in female: absent along midline, otherwise dense. Shape of T5 in female: width of posterior margin less than length. Microscupture on T6 in female: absent. Sculpture of T6 in female: smooth along midline, densely and finely punctate laterally. Macrosculpture of T2 in male: reticulate rugose throughout. Macrosculpture of medial T3 in male: weakly rugulose. Macrosculpture of lateral T3 in male: punctate rugose. Macrosculpture of T4 in male: punctate rugulose laterally. Punctation of T4 in male: sparse along midline, otherwise dense. Macrosculpture of T5 in male: weakly rugulose laterally. Punctation of T5 in male: sparse along midline, otherwise dense throughout. Sculpture of S2: coarsely punctate throughout. Prominent longitudinal median carina on S2: absent.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in female: hyaline with transverse infuscate band medially. Color of forewing in male: hyaline with transverse infuscate band medially. Color of hind wing: hyaline 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: spectral.

Diagnosis.

Bidentate mandibles are present in two known species of Trichoteleia , Trichoteleia bidentata and Trichoteleia prolixa . Trichoteleia bidentata may be separated from Trichoteleia prolixa by the coarsely sculptured, relatively narrow gena and the less extreme length of the metasoma.

Etymology.

The adjectival epithet bidentata refers to the number of mandibular teeth in this species.
