The interpretation of some Conopidae (Diptera) described by Robineau­Desvoidy Author Stuke, Jens-Hermann Author Clements, David K. text Zootaxa 2005 886 1 12 journal article 10.5281/zenodo.170914 de030dcc-8f78-4d62-b81e-2a49361f55cc 1175­5326 170914 "Heterellia petiolata R. D." A male of Myopa palliceps (Bigot, 1887) . The specimen is well preserved. The specimen bears the following labels: (1) "M. / petiolata / ɗ / coll. Big." [round, white label]; (2) "Heterellia / petiolata R. D." [light­blue label]. An unpublished manuscript name. It is possible that Robineau­Desvoidy did not intend to publish this as new species but was instead assigning the specimen to his personal concept of Conops petiolata Linnaeus, 1767 . However, this is perhaps unlikely as it would have required a gross error of identification by Robineau­Desvoid, since the latter is accepted to be a species of Physocephala ( Thompson 1997 ) .
