ID Info:
Keying to Subfamily of Pompilidae: (The keys are included on The Pompilid Project website.)
1. - Mesofemur and metafemur without subapical spine-like setae set in grooves or pits; Metatibia with a series of teeth along dorsal margin; Metatibia with apical spine-like setae of more or less uniform length, the setae not splayed; Tarsomere 5 ventrally without distinct median row of setae, with pair of submedian rows of setae; Fore wing with vein Cu1 simple at base, without any definite downward deflection, such that the second discal cell (2D) is without a posterior "pocket" = 2
2. - Pronotum without distinctly flattened dorsal and vertical faces; more continuously curved, in lateral view; Pronotum without anterior-median sulcus. Clypeus convex to flattened, but never plate-like and glabrous = Subfamily Pepsinae
Keying to Genera of Subfamily Pepsinae:
1. - Subgenital plate not laterally compressed; fore wing crossveins 2 rs-m and 3 rs-m not similar in appearance, usually one or both not continuously curved; claws normally dentate = 2
2. - Tergite 1, in dorsal view, with the sides evenly convergent anteriorly or slightly convex, in lateral view with a suture delimited a laterotergite; male genitalia with parapenial lobe not decurved at apex - Tribe Pepsini = 3
3. - Mandible with two teeth (a large apical point plus a smaller subapical internal point); dorsal edge of hind tibia with a serrate row of teeth; cardo of maxilla without a fascicle of long hairs = 4
4. - Second recurrent vein meeting the second cubital cell at about its apical 0.1 (plate 1, figure 3, of the Townes key, below = H. u. ochroptera ♀); empodium about 0.75 as wide as the subapical width of the last tarsal segment, its apical fringe of bristles containing about 14 to 40 bristles; first discoidal cell occupied basally by a distinct subcircular irregularity in the membrane; large or very large species = Genus Hemipepsis Dahlbom 1844
Keying to Subspecies of Genus Hemipepsis: (Townes 1957)
Here is a link to the key, from the Smithsonian Libraries webite: Nearctic Wasps of the Subfamilies Pepsinae and Ceropalinae
(Males)
1. - Wings mostly orange, fuscous at the base and apex; flagellum blackish = 2
2. - Nervellus beyond the cubitella by about 0.6 the average width of the submedian cell; suberect hair on clypeus and face averaging about 0.4 as long as the median length of the clypeus - SUBSPECIES OF USTULATA = 3
3. - Base of forewing infuscate for a distance equal to 0.5 or more the length of the anal lobe; base of hind wing infuscate for a distance equal to 0.8 or more the length of the anal lobe; forewing averaging about 20mm long = Subspecies ustulata ustulata Dahlbom
