Description.

Female Anterior width of T5: 0.31 mm (n=1). Female body length: 4.55 mm (n=1). Female Length of t5 in female: 0.62 mm (n=1). Female Posteroir width of T5: 0.21 mm (n=1). Color of head: black throughout. Central keel of frons: present, bifurcating ventrally around interantennal process. Sculpture of medial frons in female: smooth. Number of mandibular teeth: two. Basal node on mandible: absent. Sculpture of frons below median ocellus: densely punctate throughout. Sculpture of posterior vertex: densely punctate. Sculpture of gena: dorsoventrally strigose. Basiconic sensillum on A7: absent.

Color of mesosoma in female: dark brown to black. Sculpture along posterior pronotal sulcus: striate, striae short and poorly defined. 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 medially, sparsely punctate laterally. Sculpture along ventral half of prespecular sulcus: coarsely punctate. Sculpture of posterolateral mesepisternum: coarsely 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: coxae and femora dark brown, trochanters, tibiae and tarsi pale brown to yellow.

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 strigose throughout. Macrosculpture of medial T3 in female: rugulose. Macrosculpture of lateral T3 in female: longitudinally strigose. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: longitudinally strigose. Punctation of T4 in female: sparse in medial third, moderately dense laterally. Macrosculpture of T5 in female: absent. 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: smooth with fine setigerous punctures laterally. 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 infuscate patch anad of R. 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: nebulous.

Diagnosis.

The combination of a conspicuously elongate metasoma and bidentate mandibles renders this species rather straightforward to identify.

Etymology.

The adjectival epithet prolixa, meaning "stretched out" or “long” in Latin, refers to the length of the metasoma in this species.
