Genus italicMesorhaga/italic Schiner, 1868 (Diptera, Dolichopodidae) on Madagascar, with Description of a New Species

摘要

A new species of the genus Mesorhaga from the Ranomafana National Park on Madagascar is described and an identification key to three Madagascan species is provided. Mesorhaga negrobovi sp. n. is very close to M. pauliani in habitus, differing clearly in its hypopygial cercus trifurcate at the middle as opposed to cercus trifurcate at apex in M. pauliani .
