Abstract
Eleven new species of Amblypsilopus Bigot, 1888 from Madagascar are described and illustrated: A. analamazaotra sp. nov., A. andasibensis sp. nov., A. ankarana sp. nov., A. bairae sp. nov., A. fianarantsoa sp. nov., A. freidbergi sp. nov., A. friedmani sp. nov., A. leonidi sp. nov., A. marinae sp. nov., A. olgae sp. nov., and A. romani sp. nov. New species differ from other representatives of the genus in morphology of male surstylus and cercus mainly and male secondary sexual characters on legs. A. flavus (Vanschuytbroeck, 1962) is redescribed. Presently, ca 60 species of Amblypsilopus are known from the Afrotropical region, and 25 species are found on Madagascar. Western Indian Ocean species are associated with the Indo-Pacific A. pallidicornis group, the Pantropical A. abruptus group and the Madagascan A. stuckenbergi group of species. An identification key to males of 28 species of Madagascar and adjacent islands is compiled for the first time.
Highlights
The sciapodine genus Amblypsilopus Bigot, 1888 is known from all realms with about 350 species worldwide, being highly diverse in the tropical belt of the Earth (Grichanov 2017)
Regarding the western Indian Ocean islands, Lamb (1922) found A. pallidicornis (Grimshaw, 1901) in the Seychelles and associated a series of females from these Islands with the Oriental A. simplex (De Meijere, 1910); the latter being a rare Javanese species (Bickel 1994) that must be excluded from the Afrotropical Region (Grichanov 1996; Meuffels & Grootaert 2009)
Almost all (93%) of the known Madagascan and Mascarene species of Amblypsilopus are endemic to their islands
Summary
The sciapodine genus Amblypsilopus Bigot, 1888 is known from all realms with about 350 species worldwide, being highly diverse in the tropical belt of the Earth (Grichanov 2017). Regarding the western Indian Ocean islands, Lamb (1922) found A. pallidicornis (Grimshaw, 1901) in the Seychelles and associated a series of females from these Islands with the Oriental A. simplex (De Meijere, 1910); the latter being a rare Javanese species (Bickel 1994) that must be excluded from the Afrotropical Region (Grichanov 1996; Meuffels & Grootaert 2009). Vanschuytbroeck (1952, 1957, 1962) described three sciapodine species from Madagascar in three different genera, which were later associated with Amblypsilopus He reported A. rectangularis (Parent, 1937) from there (material was not found later); this doubtful species was originally described from a female from the Democratic Republic of the Congo and must be excluded from the Madagascan fauna (Grichanov 1998). 11 new species of the genus from the Republic of Madagascar are described, and a revised identification key to males of 28 species of Madagascar and adjacent islands is provided
