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.
