Heptascelio lugens Kieffer, 1916: 58  (original description); Kieffer, 1926: 345 (description); Masner, 1976: 16 (type information); Narendran & Ramesh Babu, 1996: 89, 90 (description, keyed).

Description. Female body length: 4.4–4.6 mm (n= 4). Male body length: 4.1 mm (n= 1). Body color of female: entirely dark, dark brown to black. Color of female antenna: dark brown to black throughout, extremities of A 1, A 2 lighter in color. Color of wing membrane: with weak general brown infuscation, longitudinal streak below submarginal vein weak. Color of legs: coxae dark brown, femora largely brown, legs otherwise brownish yellow. Body color of male: entirely black. Color of male antenna: brown to dark brown throughout.

Sculpture of occiput and posterior vertex: coarsely punctate. Sculpture of frons below ocellus in female: coarsely punctate. Shape of dorsal margin of frontal scrobe: evenly arcuate, weakly produced. Sculpture of frontal depression in female: coarsely punctate ventrally and laterally, otherwise 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: longitudinally strigose. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: sparsely punctate, with broad smooth areas between punctures, with weak indications of longitudinal rugulae. Sculpture of mesoscutum in male: sparsely punctate, with broad smooth areas between punctures, with weak indications of longitudinal rugulae. Parapsidal line: present, clearly impressed. Mesoscutellum shape: nearly parallel-sided, apex weakly excavate, with weak median longitudinal impression. Sculpture of female mesoscutellum: areolate rugose. Scutellar points of female: moderately elongate, narrow, acute, curving medially. Sculpture of male mesoscutellum: areolate rugose. Scutellar points of male: narrow, short, acute. Posterior surface of propodeum: irregularly areolate, without distinct paramedian keel. 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, parallel-sided in ventral half, open, moderately wide, weakly fusiform, with column of elongate foveae. Netrion setation: densely setose. Sculpture of lateral pronotum posterior to epomial carina: coarsely sculptured, coarsely rugulose throughout. Setation of posterior half of lateral pronotum: with numerous scattered setae, densest near spiracle. Sculpture of mesopleural scrobe: smooth. Sculpture of lower mesepisternum: rugulose to punctate. Sculpture of metapleuron: areolate rugose above, with smooth or finely sculptured field ventrally. 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: moderately to densely setose. Sublateral lamella on T 1: distinctly raised more or less perpendicular to T 1. 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: strongly longitudinally rugose. Sculpture of S 2, S 3 of male: strongly longitudinally rugose. Distribution of felt fields: present on S 2 –S 3.

Diagnosis. Heptascelio lugens  is similar to H. paralugens  , H. dayi  , and H. bivius  , and may be distinguished by the sparsely punctate and weakly rugulose mesoscutum, absence of notauli, and punctate mesoscutellum (Figs. 49, 51).

Comments. Masner (1976) noted that the holotype (Figs. 51, 52) is a male, not a female as reported in the original description (Kieffer 1916).
