Bicolletopsis Engel, new subgenus ZooBank: urn:lsid:zoobank.org:act: 5F62D813-F55D-48D9-AAC5-DAB58A27119B TYPE SPECIES: Bicolletes pseudozonatus Moure, 1954. DIAGNOSIS: This group includes those species that have traditionally been most readily recognized as Bicolletes s.l. Like the previous subgenus, this group has the marginal line of the basal area of the propodeum distinct (not effaced as in Bicolletes s.str.), while the subhorizontal basal area is finely tessellate, coriaceous, or transversely striate, but typically longer than the metanotum. The hind wing has 5–7 distal hamuli, while the forewing marginal cell apex is rounded and sometimes feebly appendiculate. The metasoma is typically dark brown to black. ETYMOLOGY: The new subgeneric name is a combination of Bicolletes Friese and the Ancient Greek ópsis (ὄψῐς, meaning “view” or “appearance”). The gender of the name is feminine.
