Identification
This species is reported to be close to N. vincta but male with slightly more swollen
Reprinted from Broemling and Moalif, 1988


Nomada (Pachynomada) utahensis Moalif NEW SPECIES Holotype Male, Allotype Female.-Pinned with holotype "Topaz Ut. VIII-12-1949 Geo. E. Bohart, Helian thus annuus. " Type Depository, United States National Museum.


Diagnosis.-3 sub-marginal cells, terga with yellow transverse median bands, sides of propodeum yellow, with long pubescence, antennal scape not globose (widest at apex or just below), yellow mesopleural band if complete (rare) is expanded upwards to pronotal lobe, mesopleural interpunctural spaces below scrobal suture reduced to thin lines. 216 PAN-PACIFIC ENTOMOLOGIST

Male.-Length 9.3-12.6 mm, forewjng length 7.3-8.9 mm, hindwing length 5.8-7.8 mm; antennal scape widest at apex, shallowly punctured, IPS smooth and shiny; 000 < 100 < MOOM, MLOD = MOD; labrum produced into a beak apically; acetabular carina elongate, lamellate; pre lobar carina thin, prominent; pronotal ridge rounded apically; scutal punctures with sharply angulate rims; tegulae evenly punctate, IPS polished; scutellum faintly depressed medially; metapleuron with ventral half punctate, shiny; procoxal spine rudiment present; hind tibial apex with 5 light ferruginous bristles; forewing with 3 submarginal cells; COLOR: scape, supraclypeal area, sides of face, clypeus, complete ring around compound eyes, labrum, basal two-thirds of mandibles, pronotal ridge and lobes, tegulae, sides of scutum and two parasagittal stripes (absent in northern specimens), axillae, scutellum, metanotum, sides of propodeum, anterior mesopleuron extending up to subaxillary sclerites, posteriorly attenuated longitudinal band, hypoepimeral prominence, posterior meso- and metasternum, coxae (except basal area), majority of legs, terga (except dark apical bands), sterna (except clear apical impunctate bands and dark brown base of sternum I), bright yellow: remainder of body black.

Female.-Length 9.6-11.5 mm, forewing length 8.0-9.9 mm, hindwing length 6.2-7.6 mm; differs from male in scape not inflated, facial markings frequently ferruginous, dark areas of integument commonly ferruginous, not black as in males, legs somewhat darker than males. Discussion.-This species is very close to vincta. It is possible that it represents a western form of that species, but the authors feel sufficient structural differences justify its specific status. The shape of the antennal scape in male Pachynomada can vary and utahensis with unusually swollen scapes can be difficult to distinguish from vincta with unusually narrow scapes. The females of these two species can be difficult to separate, but the tergal banding and the dark color of the thorax of vincta females makes identification possible.
