Remarks. Carriker (1903) described C. extraneum from a single female associated with an erroneous host, with the correct host interpreted to be R. swainsonii . Subsequently, Carriker [and Diaz­Ungria] (1961) designated and described an allotype and paratype male, an action counter to accepted nomenclatoral practice. His illustrations and descriptive details are consistent with what we recognize here as M. extranea .
