Description. Female body length: 3.2–3.3 mm (n= 2). Male body length: 3.7 mm (n= 1). Body color of female: entirely dark, dark brown to black. Color of female antenna: A 1 dark brown, A 2 –A 5 off-white, A 6 –A 12 dark brown to black. Color of wing membrane: with faint brown infuscation throughout, with strong dark streak below submarginal vein. Color of legs: coxae dark brown to black, femora dark brown, legs otherwise very pale brown, nearly white. Body color of male: entirely black. Color of male antenna: brown to dark brown throughout.

Sculpture of occiput and posterior vertex: with strong transverse rugae. 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: diagonally striate laterally, smooth medially. 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: longitudinally strigose. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: longitudinally strigose with fine sculpture in interspaces. Sculpture of mesoscutum in male: longitudinally strigose, with strong transverse sculpture in interspaces. Parapsidal line: absent. Mesoscutellum shape: semicircular, posteriorly distinctly sloping ventrad, without distinct median longitudinal furrow. Sculpture of female mesoscutellum: longitudinally strigate. Scutellar points of female: narrow, elongate, acute. Sculpture of male mesoscutellum: longitudinally strigose. Scutellar points of male: broad, short, acute. Posterior surface of propodeum: with distinct straight longitudinal paramedian keel arising from apex of inner propodeal projection, with medial area with elongate areolae, bounded laterally by distinct paramedial carinae. Length of outer propodeal projection in female: elongate, extending near or beyond apex of T 1, distinctly longer than inner propodeal projection. Sculpture of propodeum between http://www.morphbank.net/?id= 224269 inner and outer propodeal projections: largely smooth, with variably developed diagonal carinae. Netrion shape: strongly narrowed, nearly linear, foveae on surface nearly as high as wide. 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: largely glabrous, setae limited to small patch near spiracle. Sculpture of mesopleural scrobe: smooth medially, elsewhere rugose. Sculpture of lower mesepisternum: rugulose to punctate. Sculpture of metapleuron: irregularly longitudinally rugose, with smooth field medially. 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: indicated as low carina. Sculpture of T 2 –T 4: longitudinally striate, with fine cross striae, punctures, smooth or finely punctulate transverse band apically. Setation of laterotergites: very sparsely 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: nearly smooth, with scattered setigerous punctures. Distribution of felt fields: present on S 2 –S 3.

Diagnosis. Heptascelio albipes  is similar to the cohort of African species H. strigatus  , H. anthonyi  and H. watshami  . It may be distinguished from them immediately by the light-colored tarsi and fine longitudinal carinae on the mesoscutum (Figs. 1, 3).

Etymology. The epithet albipes  refers to the light-colored tibiae.
