Etymology. From the Latin, “ gloriosus ”, referring to the attractive appearance of this species.

Discussion. Bubaces gloriosus sp. nov., is included in the “ castaneus ” group because its total length is greater than 4.70 mm.

Bubaces gloriosus sp. nov., is segregated by having the dorsal surfaces of the pronotum, clavi and coria glabrous, each corium has a circular yellow to creamy-yellow subapical spot, the head has a shallow ventral longitudinal sulcus, and the rostrum reaches the posterior border of abdominal sternite IV or sometimes to the middle third of V. In B. convergens , the must similar species, the dorsal surfaces of pronotum, clavi and coria are clothed with fine erect and longer hairs, and each corium lacks a circular yellow, to creamy yellow subapical spot.
