Description. Female body length: unknown. Male body length: 2.6 mm (n= 1). Body color of female: unknown. Color of female antenna: unknown. Color of wing membrane: generally hyaline throughout. Color of legs: tarsi light brown, otherwise brown to dark brown throughout. Body color of male: entirely dark brown. Color of male antenna: brown to dark brown throughout.

Sculpture of occiput and posterior vertex: irregularly rugulose. Sculpture of frons below ocellus in male: transversely striate. Shape of dorsal margin of frontal scrobe: distinctly incised medially, strongly produced anteriorly. Sculpture of frontal depression in male: diagonally striate laterally, smooth medially. Sculpture of gena: with irregular, nearly longitudinal rugulae. Setation of gena: with numerous strong, erect, dark bristles amid shorter setation. Shape of mandibles: elongate, extending ventrally below head, tips meeting apically.

Sculpture of dorsal pronotum: coarsely reticulate. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: unknown. Sculpture of mesoscutum in male: sparsely punctate, largely smooth. Parapsidal line: present, clearly impressed. Mesoscutellum shape: broad, weakly convex, http://atbi.biosci.ohio-state.edu/HymOnline/map-large.html?id= 223409 21. http://zoobank.org/urn:lsid:zoobank.org:specimen:0BE0B 9 B 3-6 E 19 - 4 F 97-955 E-DBAD054F 2 EAF http://www.morphbank.net/?id= 224267

apex broadly rounded. Sculpture of female mesoscutellum: unknown. Scutellar points of female: unknown. Sculpture of male mesoscutellum: coarsely reticulate. Scutellar points of male: apex of mesoscutellum rounded, points entirely absent. Posterior surface of propodeum: with medial area covered by elongate areolae, bounded laterally by irregular carinae. Length of outer propodeal projection in female: unknown. Sculpture of propodeum between inner and outer propodeal projections: areolate rugose. Netrion shape: narrow, gradually widened ventrally, foveae on surface distinctly wider than high. Netrion setation: glabrous. Sculpture of lateral pronotum posterior to epomial carina: with small smooth field near posterior margin, elsewhere finely rugulose. Setation of posterior half of lateral pronotum: largely glabrous, setae limited to small patch near spiracle. Sculpture of mesopleural scrobe: finely microreticulate to smooth. Sculpture of lower mesepisternum: finely microreticulate, nearly smooth, sparsely punctate. Sculpture of metapleuron: areolate rugose. Fore wing venation: reduced to basal stub of R, with pale pseudostigma in wing disk. Submarginal vein bristles: with 1–2 dark bristles near base of fore wing. Long dark bristles on legs: present on all femora, tibiae.

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: glabrous. Sculpture of S 2, S 3 of female: unknown. Sculpture of S 2, S 3 of male: irregularly longitudinally rugulose, apex of S 3 nearly smooth. Distribution of felt fields: present on S 3 only.

Diagnosis. This species is most similar to Heptascelio dispar  . In the male sex, H. aquilinus  may be recognized by the largely smooth mesoscutum (Fig. 14) and the tremendously elongate mandibles (Figs. 12, 15, 16).

Etymology. The epithet aquilinus  , of eagles, refers to the beaklike mandibles.
