New species of Lonchaeidae (Diptera: Schizophora) from Madagascar

Six new species of Lonchaeidae in two genera are described from the island of Madagascar: Dasiops kaplani n. sp., Dasiops pencila
n. sp., Silba andasibe n. sp., Silba longigonite n. sp., Silba macrogonite n. sp. and Silba setigonite n. sp. One species new to Madagascar— Silba virescens Macquart, 1851—is recorded, and previous records from the islands are re-evaluated. The known fauna now numbers 12 species in three genera. A key is provided
to all the Lonchaeidae species presently known from the island. The presence of further undescribed species of Lonchaea Fallén, 1820 and Dasiops Rondani, 1856 is noted.
