Abstract
New taxa of Dipseudopsidae from Madagascar are described, including a new genus, Ollieopteryx, and three new species, Ollieopteryx fianarana, O. inopinata, and O. dakshan. The hypothetical phylogenetic tree of the Dipseudopsidae (Weaver & Malicky 1994) is revised to include Ollieopteryx, an isolated relic. Scenarios on the historical biogeography of the family are hypothesized.
