Description. Female body length: 3.8–4.1 mm (n=2). Male body length: unknown. Body color of female: entirely dark, dark brown to black. Color of female antenna: A1 brown, A2–A5 yellow, A6–A12 generally brown to dark brown, A12 lighter. Color of wing membrane: moderately infuscate throughout, streak below submarginal vein darkly pigmented. Color of legs: entirely yellow. Body color of male: unknown. Color of male antenna: unknown.

Sculpture of occiput and posterior vertex: areolate rugose, with distinct transverse tendency. Sculpture of frons below ocellus in female: dorsoventrally striate. Shape of dorsal margin of frontal scrobe: evenly arcuate, weakly produced. Sculpture of frontal depression in female: entirely smooth. Sculpture of gena: with irregular dorsoventral rugae. Setation of gena: with short, uniform setae, with few short bristles interspersed. Shape of mandibles: normal length, crossed transversely below head when closed, tips overlapping.

Sculpture of dorsal pronotum: coarsely punctate. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: sparsely punctate, with broad smooth areas between punctures. Sculpture of mesoscutum in male: unknown. Parapsidal line: present, clearly impressed. Mesoscutellum shape: roughly trapezoidal, sides converging apically, apex weakly excavate, without distinct median longitudinal impression. Sculpture of female mesoscutellum: coarsely punctate. Scutellar points of female: absent, mesoscutellum with rounded lobes laterally. Sculpture of male mesoscutellum: unknown. Scutellar points of male: unknown. Posterior surface of propodeum:. Length of outer propodeal projection in female: rather short, extending at most to midlength of T1, slightly longer than inner propodeal projection. Sculpture of propodeum between inner and outer propodeal projections: areolate rugose, with distinct longitudinal tendency. Netrion shape: moderately wide, weakly fusiform, with column of elongate foveae. Netrion setation: glabrous. Sculpture of lateral pronotum posterior to epomial carina: smooth. Setation of posterior half of lateral pronotum: largely glabrous, setae limited to small patch near spiracle. Sculpture of mesopleural scrobe: smooth. Sculpture of lower mesepisternum: smooth. Sculpture of metapleuron: largely smooth. Fore wing venation: well-developed, with R, r-rs clearly visible. Submarginal vein bristles: with dark bristles in basal half of submarginal vein. Long dark bristles on legs: absent.

T1 depression: glabrous or sparsely setose. Sublateral lamella on T1: indicated as low carina. Sculpture of T2–T4: longitudinally striate, with fine cross striae, punctures, smooth or finely punctulate transverse band apically. Setation of laterotergites: setose. Sculpture of S2, S3 of female: strongly longitudinally rugose. Sculpture of S2, S3 of male: unknown. Distribution of felt fields: present on S2–S3.

Diagnosis. Heptascelio teres is very similar to the sympatric species H. sicarius . The former may be distinguished by the shorter outer propodeal projection, the downturned metascutellar spine, the well-defined parapsidal lines, and the longitudinally carinate propodeum. The punctate sculpture of the mesoscutum is found in several species from Asia, H. dayi , H. lugens , H. paralugens , and H. bivius . Heptascelio teres may be distinguished by the yellow coxae and glabrous netrion (Fig. 90).

http://www.morphbank.net/?id=224252 Etymology. The epithet teres , meaning polished, smooth, refers to the sculpture of the lateral portions of the mesoscutum.
