Differential diagnosis
Both sexes of this species are easy to distinguish from other members of the group by having the collar, scutellum and metanotum, or at least their dorsal parts, ferruginous instead of black ( Figs 127–128 View Figs 124–128. 124–125, 127 ).
Etymology
‘ Occidentalis ’ is a Latin adjective meaning ‘western’. It describes the geographic distribution of this species and also references the name of the closely related S. meridionalis .

Description
Female
SIZE. 20.1–23.9 mm.
COLOR. Black except for the following, which are ferruginous: basal half of mandible, scape, pedicel, flagellomeres I–V, clypeus, legs from trochanter onward excluding apical half of claw, collar dorsally, tegula, dorsal part of scutellum and metanotum, and apical segment of metasoma. Wings fuscous, forewing with conspicuous purple iridescence.
VESTITURE.Appressed and erect setae on clypeus, paraocular region, collar and scutum golden, appressed and erect setae on propodeal enclosure brown. Erect propodeal setae oriented perpendicularly, slightly curved towards anterior. Clypeus without glabrous spot. Scutellum densely and finely pubescent.
STRUCTURE. Free clypeal margin slightly stepped medially. Clypeus without indentation and carina. Scutellum convex. Metanotum not raised, not bituberculate. 2 nd recurrent vein joins sligthly proximal from interstitium between submarginal cells II and III. Propodeal enclosure with numerous very fine transversal ridges. Foretarsomere I 2.2–2.3× length of antepenultimate spine. Petiole length 1.2–1.4 × its medial width.
Male
SIZE. 17.1–20.1 mm.
COLOR. Black except for the following, which are ferruginous: basal half of mandible, clypeus excepting dorsolateral area, scape, pedicel, flagellomeres I–V, collar, prepectus, tegula, scutellum and occasionally metanotum dorsally, apical segment of metasoma, legs from trochanter onward excepting trochanters, and femora of mid- and hindlegs dorsally. Wings fuscous, with conspicuous purple iridescence.
VESTITURE. Appressed setae on clypeus and paraocular area silvery-golden, on collar, scutum and propodeal enclosure ferruginous-brown, on posterior margin of propodeum silvery. Erect setae on clypeus, paraocular region, collar, scutum and propodeal enclosure ferruginous-brown or black, on posterior margin of propodeum silvery. Erect propodeal setae oriented perpendicularly, slightly curved towards anterior. Lower part of clypeus glabrous. Scutellum densely and finely pubescent.
STRUCTURE. Free clypeal margin medially concave, very inconspicuously stepped medially. Scutellum convex. Metanotum raised, not notably bituberculate. 2 nd recurrent vein joins slightly proximal from interstitium between submarginal cells II and III. Propodeal enclosure without any notable ridges. Posterior margin of metasomal tergum VII convex. Posterior margin of metasomal sternum VII simple, of metasomal sternum VIII triangular. Penis valvae without conspicuous modifications. Petiole length 1.9× its medial width. Flagellomere V with narrow placoid covering almost its entire length.
