title: Revision of the Bicyclus ignobilis species-group (Lepidoptera: Nymphalidae: Satyrinae) with descriptions of two new species.
abstract: The ignobilis-group of the genus Bicyclus Kirby 1871 is revised. The species-group contains six species with a distinct wing pattern, but limited intraspecific variation, distributed across tropical African rainforest. We investigate a set of more than 1000 specimens from a range of museum collections, including some type material, and thoroughly update the biogeographical knowledge for the group. We also describe two new species as members of the group. The included species are: Bicyclus ignobilis (Butler 1870) stat. rev., B. rileyi Condamin 1961, B. maesseni Condamin 1971, B. brakefieldi Brattström 2012, B. ottossoni sp. nov. and B. vandeweghei sp. nov. Due to observing a gradual morphological cline within B. ignobilis without any sharp transitions we suppress the previously identified subspecies B. ignobilis eurini Condamin & Fox 1963 syn. nov. and B. ignobilis acutus Condamin 1965 syn. nov.
