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.

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.
