Description. Female body length: 3.6–4.3 mm (n= 13). Male body length: 3.3–3.8 mm (n= 14). Body color of female: entirely dark, dark brown to black. Color of female antenna: dark brown to black throughout. Color of wing membrane: moderately infuscate throughout, streak below submarginal vein darkly pigmented. Color of legs: coxae dark brown, femora largely brown, legs otherwise brownish yellow. Body color of male: entirely black, head and mesosoma black, metasoma dark brown. Color of male antenna: brown.

Sculpture of occiput and posterior vertex: areolate-rugose, with strong arched rugae. 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: longitudinally strigose. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: coarsely longitudinally strigose with smooth interspaces. Sculpture of mesoscutum in male: coarsely areolate rugose with distinct longitudinal tendency. 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 reticulate, with distinct longitudinal elements. Scutellar points of female: forming short, acute teeth. Sculpture of male mesoscutellum: areolate rugose. Scutellar points of male: narrow, short, acute. Posterior surface of propodeum: with distinct straight longitudinal paramedian keel arising from apex of inner propodeal projection. 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 inner and outer propodeal projections: areolate rugose, with distinct longitudinal tendency. 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: smooth. Setation of posterior half of lateral pronotum: largely glabrous, setae http://atbi.biosci.ohio-state.edu/HymOnline/map-large.html?id= 4542 45. http://zoobank.org/urn:lsid:zoobank.org:specimen: 1779 B 27 F-F 144 - 4 A 32-9494 - 2 B 9 C 3 DBB 6 E 7 C http://www.morphbank.net/?id= 224259

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 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 cross striae laterally, sculpture effaced medially. Setation of laterotergites: setose. Sculpture of S 2, S 3 of female: nearly smooth, 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 noyesi  is restricted to Madagascar. In that fauna it is most similar to H. orarius  , from which it may be distinguished by the strigose sculpture of the mesonotum (Figs. 55, 57). From the mainland species H. watshami  , H. anthonyi  , H. albipes  and H. strigatus  it may be distinguished by the loss of the coarse sculpture on the ventral portion of the mesopleuron, large parts of the metapleuron (Figs. 54, 58), and the frontal depression (Fig. 56).

Etymology. This species is named after John S. Noyes in recognition of his contributions to understanding the diversity of Hymenoptera  .
