Our material was identified by directly comparing it with the holotypedeposited at the Naturhistoriskariksmuseet ( Stockholm, Sweden; NHRS) and another specimen deposited at the National Museum of Natural History, Smithsonian Institution (Washington D.C., United States; NMNH). Bothwere collected in the state of Rio de Janeiro, in the 19th century, by F. Sahlberg.   Type and reference material examined.  BRAZIL—[  Rio de Janeiro] • F. Sahlb.[erg] leg.; female holotype, NHRS•  Petrópolis; 1831; F.
