Taxonomy of Podoscirtinae (Orthoptera: Gryllidae). Part 3: Podoscirti- ni from Madagascar and nearest regions. Zoosystematica Rossica, 12(2), 2003: 187-215. Twelve genera belonging to a generic group with relatively primitive type of the male genitalia are characterized. They are distributed mainly in Madagascar, but some are known also from the Seychelles and Comores or from Africa; one genus possibly belong- ing to this group is known from Africa only. Six new genera, one new subgenus, and 24 new species are described; several other species are considered (including revisions of type material and information about systematic position of some forms). New synonymy is established: Kilimagryllus africanus (Walker, 1869) = Platydactylus fuliginosis Walk- er, 1869, syn. n. Lectotypes of Fryerius aphonoides and K. africanus are designated. A.V.
