Abstract

Protopiophila litigata sp.nov. is described from Ontario and Nova Scotia. McAlpine’s (1977) key to the species of Protopiophila is modified to facilitate identification of the new species. Behaviours of P. litigata and P. latipes were studied in Algonquin Park, Ontario. Whereas P. latipes reproduces on corpses in advanced stages of decay, P. litigata mates and oviposits on discarded cervid antlers, ignoring other carrion. Unlike P. latipes, males of P. litigata engage in ’mate guarding’. These traits probably represent autapomorphies of P. litigata.

Résumé

On trouvera ici la description de Protopiophila litigata sp.nov. de l’Ontario et de la Nouvelle-Écosse. La clé des espèces de Protopiophila publiée par McAlpine (1977) a été modifiée pour permettre l’identification de la nouvelle espèce. Le comportement de P. litigata et celui de P. latipes ont fait l’objet d’une étude dans le parc Algonquin, en Ontario. Alors que P. latipes se reproduit sur des charognes en état avancé de décomposition, P. litigata s’accouple et pond ses oeufs exclusivement sur les bois rejetés des cervidés, jamais sur d’autres charognes. Contrairement à ceux de P. latipes, les mâles de P. litigata s’adonnent à la “garde de leur partenaire”. Il s’agit sans doute là d’autapmorphies chez P. litigata.
