Description. Female body length: 3.9–4.0 mm (n= 2). Male body length: unknown. Body color of female: entirely dark, dark brown to black. Color of female antenna: A 1 brownish yellow, A 2 –A 5 yellow, A 6 –A 12 dark brown to black. Color of wing membrane: hyaline basally, infuscate in apical two-thirds, streak below submarginal vein weak. Color of legs: coxae dark brown, femora largely brown, legs otherwise brownish yellow. Body color of male: unknown. Color of male antenna: unknown. Sculpture of occiput and posterior vertex: areolate-rugose. Sculpture of frons below ocellus in female: areolate rugose. Shape of dorsal margin of frontal scrobe: evenly arcuate, weakly produced. Sculpture of frontal depression in female: with short transverse striae on sides, medially entirely smooth. Sculpture of gena: areolate rugose, with distinct dorsoventral tendency. 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: areolate rugose, with distinct longitudinal tendency. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: coarsely areolate-rugose. Sculpture of mesoscutum in male: unknown. Parapsidal line: absent. Mesoscutellum shape: roughly semicircular, with distinct median longitudinal impression in apical half. Sculpture of female mesoscutellum: areolate rugose. Scutellar points of female: absent, mesoscutellum with rounded lobes laterally. Sculpture of male mesoscutellum: unknown. Scutellar points of male: unknown. Posterior surface of propodeum: with medial area covered by elongate areolae, bounded laterally by irregular carinae, with sinuous paramedian keel arising from apex of inner propodeal projection. Length of outer propodeal projection in female: moderately elongate, extending to midpoint of length of T 1, distinctly longer than inner propodeal projection. Sculpture of propodeum between inner and outer propodeal projections: areolate rugose. Netrion shape: moderately wide, nearly parallel-sided, weakly widened ventrally, with single column of large foveae. Netrion setation: glabrous. Sculpture of lateral pronotum posterior to epomial carina: with smooth field dorsally, elsewhere areolate rugose. Setation of posterior half of lateral pronotum: with numerous scattered setae, densest near spiracle. Sculpture of mesopleural scrobe: finely microreticulate to smooth. Sculpture of lower mesepisternum: rugulose to punctate. Sculpture of metapleuron: areolate rugose. Fore wing venation: well-developed, with R, r-rs clearly visible. Submarginal vein bristles: with dark bristles extending length of submarginal vein. Long dark bristles on legs: absent.

T 1 depression: glabrous or sparsely setose. Sublateral lamella on T 1: absent. Sculpture of T 2 –T 4: longitudinally striate, with fine cross striae, punctures, smooth or finely punctulate transverse band apically. Setation of laterotergites: setose. Sculpture of S 2, S 3 of female: longitudinally rugulose laterally, nearly smooth medially, with scattered small punctures. Sculpture of S 2, S 3 of male: unknown. Distribution of felt fields: present on S 2 –S 3.

Diagnosis. This species is similar to H. sicarius  , H. teres  and the males of H. aquilinus  and H. dispar  in having the posterior scutellum with two broadly rounded lobes, i.e., without spines (Fig. 45). It may be distinguished from H. aquilinus  and H. dispar  by the rounded dorsal margin of the frontal depression (Fig. 46), the lack of black bristles on the legs (Fig. 43), and the well-developed fore wing venation. Heptascelio lateralis  may be separated from H. sicarius  and H. teres  by the coarse areolate rugose sculpture of the mesoscutum (Fig. 45) and the dark-colored legs (Figs. 43, 44).

Etymology. The epithet lateralis, Latin  for “of the side” is intended to draw attention to the lack of a lamella on the side of T 1.
