Talk:Melangyna viridiceps

Distribution

Thompson, F.C. (2008: 13) notes that Melangyna viridiceps has often been confused with Simosyrphus grandicornis, and specifically that Melangyna viridiceps sensu Miller (1921: 307, pl. 48, fig. 4) is a misidentification of S. grandicornis
Miller (1921: 307) reported Melangyna viridiceps from New Zealand, both from the mainland and 'it is also common on the Kermadec Islands'
Macfarlane et al. (2000) claimed that Melangyna viridiceps is present on the Kermadecs, but not in mainland N.Z.
no other recent sources record Melangyna viridiceps from New Zealand (mainland or Kermadecs)
it is therefore likely that all New Zealand (mainland or Kermadecs) records are based on misidentifications of Simosyrphus grandicornis
