Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 84

riparia Macquart, 1835 , Hidrophoria [sic]

Hidrophoria [sic] riparia Macquart, 1835: 299 . Unjustified replacement name for Potamia littoralis Robineau- Desvoidy, 1830.

MATERIAL. — As this is a replacement name, Robineau-Desvoidy’s types of littoralis are also the types of riparia . However, Robineau-Desvoidy’s collection has been largely destroyed ( Evenhuis et al. 2010: 233).

CURRENT IDENTITY. — Both Bezzi & Stein (1907: 622) and Hennig (1962d: 752) placed Potamia littoralis and H. riparia as doubtful synonyms of Dendrophaonia querceti (Bouché, 1834) , and Hennig recommended that the Robineau-Desvoidy name should be left as a nomen dubium in order to conserve this latter name. However, there is really no doubt at all from Robineau-Desvoidy’s description of the taxonomic characters and habits of his Potamia littoralis that he was describing what has subsequently been known as Dendrophaonia querceti , and I have accordingly synonymized Dendrophaonia Malloch, 1923 , with Potamia Robineau-Desvoidy, 1830 , and the species D. querceti (Bouché, 1834) with P. littoralis Robineau-Desvoidy, 1830 ( Pont 1986b: 83) .
