Description
. Female body length: 4.0–4.8 mm (n=18). Male body length: 4.2 mm (n=1). Body color of female: entirely dark, dark brown to black. Color of female antenna: dark brown to black throughout, extremities of A1, A2 lighter in color. Color of wing membrane: with weak general brown infuscation, longitudinal dark streak below submarginal vein moderately developed. Color of legs: coxae dark brown, femora largely brown, legs otherwise brownish yellow. Body color of male: head and mesosoma black, metasoma dark brown. Color of male antenna: brown.
Sculpture of occiput and posterior vertex: coarsely punctate. Sculpture of frons below ocellus in female: areolate rugose. Shape of dorsal margin of frontal scrobe: evenly arcuate, weakly produced. Sculpture of fronhttp://atbi.biosci.ohio-state.edu/HymOnline/map-large.html?id=223411 27. http://zoobank.org/urn:lsid:zoobank.org:specimen:9A8D4ABD-AC2D-4D9B-BAA6-BF523C25637C http://www.morphbank.net/?id=224265
tal depression in female: transversely rugose throughout. 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: areolate rugose, with distinct longitudinal tendency. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: longitudinally strigose, with strong transverse sculpture in interspaces. Sculpture of mesoscutum in male: longitudinally strigose, with strong transverse sculpture in interspaces. Parapsidal line: absent. Mesoscutellum shape: nearly parallel-sided, apex weakly excavate, with weak median longitudinal impression. Sculpture of female mesoscutellum: areolate rugose. 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: moderately elongate, not reaching midpoint of length of T1, subequal in length to inner propodeal projection. Sculpture of propodeum between inner and outer propodeal projections: largely smooth, with variably developed diagonal carinae. Netrion shape: moderately wide, nearly parallel-sided, weakly widened ventrally, with single column of large foveae. Netrion setation: densely setose. Sculpture of lateral pronotum posterior to epomial carina: 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: with smooth field in posteroventral quadrant, elsewhere areolate rugose. 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.
T1 depression: moderately to densely setose. Sublateral lamella on T1: distinctly raised more or less perpendicular to T1. Sculpture of T2–T4: longitudinally striate, with fine cross striae, punctures, smooth or finely punctulate transverse band apically. Setation of laterotergites: setose. Sculpture of S2, S3 of female: strongly longitudinally rugose. Sculpture of S2, S3 of male: Distribution of felt fields: present on S2–S3.
Diagnosis
. Most similar to specimens of
Heptascelio hamatus
having the frontal depression entirely sculptured (as in Fig. 42).
Heptascelio castor
may be distinguished by the well-developed and straight paramedial carinae on the propodeum and the striate sculpture between the medial and outer propodeal projections (Fig. 25).
Etymology
. Named for one of the classical twins, because of its similarity to some specimens now placed in
H. hamatus
.
