Description.

Female body length: 2.74 mm (n=1). Male body length: 2.35-2.80 mm (n=2). Color of head: dark brown to black; reddish brown. Central keel of frons: present, ending above 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: dorsoventrally strigose throughout with coarsely punctate interstices. Sculpture of posterior vertex: punctate rugulose. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: punctate rugose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: reddish brown throughout. 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: with blunt kink near intersection with metapleural sulcus. Color of legs: brown throughout.

Color of metasoma in female: reddish brown. Color of metasoma in male: dark brown to black throughout. Posterior margin of transverse sulcus on T2: straight. 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: reticulate rugose medially, longitudinally strigose laterally. Macrosculpture of medial T3 in female: reticulate rugose. Macrosculpture of lateral T3 in female: longitudinally strigose. Ma crosculpture of medial T4 in female: longitudinally strigose. Macrosculpture of lateral T4 in female: longitudinally strigose. Punctation of T4 in female: sparse throughout. Macrosculpture of T5 in female: weakly rugulose laterally. Punctation of T5 in female: moderately dense throughout. Shape of T5 in female: width of posterior margin less than length. Microscupture on T6 in female: absent. Sculpture of T6 in female: finely punctate throughout. Macrosculpture of T2 in male: reticulate rugose medially, longitudinally strigose laterally. Macrosculpture of medial T3 in male: reticulate. Macrosculpture of lateral T3 in male: longitudinally strigose. Macrosculpture of T4 in male: longitudinally strigose throughout. Punctation of T4 in male: sparse throughout. Macrosculpture of T5 in male: weakly rugulose laterally. Punctation of T5 in male: moderately 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 bands medially and apically. Color of forewing in male: hyaline throughout. Color of hind wing: hyaline throughout. Density of setation in fore wing: reduced posterior to Sc+R in basal half. 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.

Females of Trichoteleia bicolor are most similar to Trichoteleia sphaerica . The present species may be distinguished from Trichoteleia sphaerica in having two transverse bands of infuscation in the forewing (Fig. 72).

Etymology.

This species is named for the color dimorphism in the wings and body color between males and females. The epithet is a noun in apposition.
