66. Blainvillia Robineau-Desvoidy, 1830: 514.

ORIGINALLY INCLUDED SPECIES: Blainvillia palpata Robineau-Desvoidy, 1830.

TYPE SPECIES: Blainvillia palpata Robineau-Desvoidy, 1830, by monotypy.

CURRENT STATUS: Junior synonym of Hydrotaea Robineau-Desvoidy, 1830 [teste Pont (1986b: 74)].

FAMILY: MUSCIDAE.

REMARKS: Robineau-Desvoidy (1830) proposed this name twice for two different genera in this work. The Blainvillia on page 514 was for a single species collected in 1828, two years after he presented his original draft of the Myodaires to the Académie des Sciences, with an etymology “ Je dédie ce genre à M. Ducrotay de Blainville, un de mes maîtres, et l’auteur du rapport qui m’a valu les honneurs de l’impression pour les Myodaires ”. The second Blainvillia (on page 713, see entry below) has no date of collection and only a short dedication to “ M. de Blainville, auteur du Rapport sur mes Myodaires ”. It is possible that the second Blainvillia (on page 713) originally had another name and Robineau-Desvoidy changed it soon after Blainville gave his report to the Académie in 1826 in order to honor him. Two years later (in 1828), he collected a new genus in Saint-Sauveur and wanted to add it to his paper with a name honoring his “ maître ” but forgot he had already changed the name of one of his genera to honor the same person. While it is possible to synonymize this Blainvillia (1830: 514) with Hydrotaea because of its position in the text between Hydrotaea and Ophyra Robineau-Desvoidy (also a junior synonym of Hydrotaea), the type species cannot be interpreted because Robineau-Desvoidy clearly described two different species (one with plumose arista, one with pubescent arista) as the male and female of his Blainvillia palpata.
