Description.

Female body length: 3.21 mm (n=1). Color of head: reddish brown. Central keel of frons: present, bifurcating ventrally around interantennal process. Sculpture of medial frons in female: smooth. Number of mandibular teeth: three. Basal node on mandible: present. Sculpture of frons below median ocellus: punctate rugulose throughout. Sculpture of posterior vertex: punctate rugulose. Occipital rim: comprised of small to miniscule cells. Sculpture of gena: dorsoventrally strigose. Basiconic sensillum on A7: present.

Color of mesosoma in female: reddish brown throughout. Sculpture along posterior pronotal sulcus: striate, striae well defined. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow. Sculpture of medial mesoscutum: longitudinally rugulose posteriorly, transversely rugulose anteriorly. Sculpture of mesoscutellum: smooth medially, coarsely punctate laterally. Postacetabular sulcus: present as a smooth furrow. Mesopleural carina: present. Sculpture along ventral half of prespecular sulcus: punctate rugose. Sculpture of posterolateral mesepisternum: smooth except for 1 or 2 striae parallel to mesopleural carina. Sculpture of ventral surface of mesepisternum: finely 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: with blunt kink near intersection with metapleural sulcus. Color of legs: yellow throughout.

Color of metasoma in female: dark brown to black throughout. Posterior margin of transverse sulcus on T2: weakly convex. Sublateral tergal carina on T2: absent. Microsculpture on T2: present. Microsculpture on T3: present. Microsculpture on T4: present. 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: weakly longitudinally strigose. Macrosculpture of lateral T3 in female: longitudinally strigose. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: punctate rugulose. Punctation of T4 in female: absent along midline, otherwise moderately dense. Macrosculpture of T5 in female: punctate rugulose laterally. 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. Sculpture of S2: longitudinally striate throughout. Prominent longitudinal median carina on S2: absent.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in female: infuscate in apical two-thirds, white spot near apex, two white patches medially at anterior and posterior margins. 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: less than 1.5 times as long as rs. M+Cu and RS+M in forewing: nebulous.

Diagnosis.

Trichoteleia delilah is similar to Trichoteleia cincta , Trichoteleia picturata and Trichoteleia zuparokoi in the banded coloration of the wings and to Trichoteleia cincta and Trichoteleia picturata in the sculpture of the medial mesoscutum, which is transversely rugulose anteriorly and longitudinally rugulose posteriorly. It is readily separated from these three species by the presence of a basiconic sensillum on A7 (Fig. 1) and rugulose sculpture in the marginal depression of S3 (Fig. 17).

Etymology.

This aesthetically pleasing species is named for the Delilah of the Old Testament. The species epithet is a noun placed in apposition.
