Discussion: Hershkovitz’s (1944) footnoted listing of specific synonyms of O. albigularis set the precedent for Cabrera’s (1961) arrangement of the South American forms as subspecies, a viewpoint reiterated in regional studies (e.g., Handley, 1966 a, 1976). Gardner and Patton (1976) demonstrated the composite nature of Hershkovitz’s (1944) and Cabrera’s (1961) concept of albigularis ; however, the determination of priority and refinement of distributions require much museum-based research. Here we follow the taxonomy of Gardner and Patton (1976), Patton et al. (1990), and Márquez et al. (2000) in recognizing O. auriventer , O. caracolus , O. devius , O. keaysi , O. levipes , and O. meridensis as separate species (see those accounts). Gardner and Patton (1976) reassociated Cabrera’s (1961) name-combination O. a. boliviae as a junior synonym of O. nitidus . Potential and actual distribution in Venezuela evaluated using GIS techniques by Anderson (2003 b).
