http://zoobank.org/urn:lsid:zoobank.org:specimen: 530 D 4302 -EE0D- 4017 -A 5 B 3-7 CB 8 F 369 AA 3 C Description. Female body length: 4.1 mm (n= 1). Male body length: unknown. Body color of female: entirely dark, dark brown to black. Color of female antenna: dark brown to black throughout. Color of wing membrane: with faint brown infuscation throughout, with strong dark streak below submarginal vein. Color of legs: coxae dark brown to black, legs otherwise brown to dark brown. Body color of male: unknown. Color of male antenna: unknown. Sculpture of occiput and posterior vertex: coarsely punctate. Sculpture of frons below ocellus in female: coarsely punctate. Shape of dorsal margin of frontal scrobe: ecarinate, rounded onto dorsal portion of frons. Sculpture of frontal depression in female: coarsely punctate ventrally and laterally, otherwise smooth. Sculpture of gena: coarsely punctate. Setation of gena: with short, uniform setae, without bristles. 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: absent. Mesoscutellum shape: nearly parallel-sided, apex weakly excavate, with weak median longitudinal impression. Sculpture of female mesoscutellum: coarsely punctate. Scutellar points of female: forming short, sharp angles, not protruding. Sculpture of male mesoscutellum: unknown. Scutellar points of male: unknown. Posterior surface of propodeum: irregularly areolate, without distinct paramedian keel. Length of outer propodeal projection in female: moderately elongate, not reaching midpoint of length of T 1, subequal in length to inner propodeal projection. Sculpture of propodeum between inner and outer propodeal projections: coarsely punctate. Netrion shape: moderately wide, nearly parallel-sided, with two columns of large punctures. Netrion setation: densely setose. Sculpture of lateral pronotum posterior to epomial carina: coarsely punctate. Setation of posterior half of lateral pronotum: with numerous scattered setae, densest near spiracle. Sculpture of mesopleural scrobe: smooth. Sculpture of lower mesepisternum: with distinctly separated, coarse punctures. Sculpture of metapleuron: coarsely punctate. 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.

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: unknown. Distribution of felt fields: present on S 2 –S 3.

Diagnosis. Heptascelio dayi  is most similar to the cluster of species H. bivius  , H. lugens  and H. paralugens  . It is distinguished by the lack of notauli and the punctured, not areolate, mesoscutellum (Fig. 29).

Etymology. Named for the collector, Mick Day.
