Head shining reddish brown; tylus and antennal segments I-IV shining pale chestnut orange; basally with two iridescent spots, one on either side of midline, each spot consisting of a series of parallel ridges. Pronotum with anterior lobe dark shining reddish brown, posterior lobe pale shining chestnut, with humeri and anterolateral borders yellow to dark yellowish orange. Scutellum, clavi and coria dark shining reddish brown; costal margins of coria dark yellowish orange; hemelytra tricolored, membranes at base and near apical corial borders shining chestnut, followed by a transverse hyaline band which continues along each border, remainder pale yellow gray; dorsal abdominal segments shining chestnut, with lateral margins of segments III-V shiny yellow. Ventral coloration.

Etymology. The specific name is in reference to the Western distribution of this species.
Discussion. Differential diagnosis. Bubaces occidentalis sp. nov., is included in the “ castaneus ” group by having the total length of the body greater than 4.70 mm. Bubaces occidentalis is further segregated by having the dorsal surfaces of the pronotum, clavi and coria clothed with long hairs, the coria lacking circular yellow to creamy yellow subapical spots, and its distribution being restricted to the western parts of Mexico. In B. castaneus , the surfaces of the pronotum, clavi and coria are glabrous, the coria also lack circular yellow to creamy yellow subapical spots, but its has a wide distribution, occurring from southern Mexico (States of Campeche, Quintana Roo and Yucatan) throughout Central and South America.
