Description.

Female body length: 2.65 mm (n=1). Color of head: dark brown to black. Central keel of frons: present, extending onto interantennal process. Sculpture of medial frons in female: smooth. Number of mandibular teeth: three. Basal node on mandible: absent. Sculpture of frons below median ocellus: punctate laterally, mostly smooth medially. Sculpture of posterior vertex: moderately punctate. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: punctate rugose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: posterior metapleuron brown, otherwise orange. Sculpture along posterior pronotal sulcus: rugulose. Notaulus: 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 medially, sparsely punctate laterally. Postacetabular sulcus: comprised of small cells. Mesopleural carina: present. Sculpture along ventral half of prespecular sulcus: punctate. Sculpture of posterolateral mesepisternum: smooth except for 1 or 2 rows of fine punctures parallel to mesopleural carina. 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: straight to moderately convex. Color of legs: brown throughout.

Color of metasoma in female: dark brown to black throughout. Posterior margin of transverse sulcus on T2: straight. Sublateral tergal carina on T2: absent. Microsc ulpture 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: longitudinally strigose throughout. Macrosculpture of medial T3 in female: absent. Macrosculpture of lateral T3 in female: weakly longitudinally strigose. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: absent. Punctation of T4 in female: absent along midline, otherwise sparse. Macrosculpture of T5 in female: absent. Punctation of T5 in female: sparse through out. 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: finely punctate 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 throughout. 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.

The most distinguishing character of Trichoteleia xantrox is the transverse furrow on T2, which has the anterior and posterior margins parallel across the entire tergite (Fig. 298). Trichoteleia jiro and Trichoteleia afo have the margins of the furrow parallel medially but converging laterally. Trichoteleia xantrox may also be separated from these two species by the deep furrow laterad of the orbital carina that extends to the vertex along the inner margin of the eye (Fig. 297).

Etymology.

The epithet xantrox is a meaningless, euphonic combination of letters. It is to be treated as a noun in apposition.
