Type locality: Barra do Rio Negro , Manaos , Amazonas , Brazil . Distribution: Region 5. Amazonian species, distributed in southern, central, and upper Amazon in Brazil , Peru , Ecuador , Bolivia , Colombia , and the Guianas. In Venezuela all populations known as O. taurinus must be revised. Jungfer et al. (2013) identified two candidate species under this name from Venezuela , one in NW Amazonas State , and another from the extreme south Amazonas State (Appendix 1). Jungfer et al. (2013) restricts the presence of O. taurinus sensu stricto out of Venezuela . However, populations of O. “taurinus ” from southeastern Venezuela would remain without identification. For now, authors restrict distribution of O. aff. taurinus to the lowlands and uplands of Bolívar State . Remarks : A well-recognized species complex. In Venezuela at least three putative species are reported under this name ( Jungfer et al. 2013 ; Appendix 1).
