Orthellia cyaniceps, Seguy, 1933

Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 57-58

cyaniceps Séguy, 1933 , Orthellia

Orthellia cyaniceps Séguy, 1933: 65 . Lectotype ♀, “ Île Bourbon ” ( La Réunion), by present designation, in MNHN.

MATERIAL. — Under no. 974 of the Macquart collection in MNHN, there is 1 ♀ labelled by Macquart as “cyaniceps”. This is a manuscript name that was never published by Macquart, but it was mentioned by Séguy (1933) in his key to world Orthellia Robineau-Desvoidy, 1830 (now correctly called Neomyia Walker, 1859 ). The name must therefore be attributed to Séguy. Séguy mentions both ♂ and ♀ characters in his key couplet for O. cyaniceps , and so the ♀ in the Macquart collection can only be a syntype. No ♂ has been located. I have labelled and designate herewith this ♀ as lectotype. It is rather mouldy, but all parts are present except for a few tarsomeres. It has a turquoise accessions disc with the number 4112.33, which refers to a collection from La Réunion made by Bréon.

CURRENT IDENTITY. — This is a specimen of Neomyia viridifrons ( Macquart, 1843) , and Orthellia cyaniceps is a junior synonym of this name ( Pont 1980: 729).
