Amblypsilopus
Bigot, 1888
Amblypsilopus is a large of () containing approximately 350 described . The genus is distributed across tropical and subtropical regions worldwide, with particularly high diversity in the Afrotropical region where about 60 species occur, including 25 on Madagascar alone. The genus is possibly polyphyletic and requires further taxonomic revision. Species identification relies heavily on male , particularly the surstylus and , along with male secondary sexual characters on the legs.

Distribution
Pantropical and subtropical distribution with records from the Afrotropical region (approximately 60 , including 25 on Madagascar), Indo-Pacific region, and the Americas (including the United States). Western Indian Ocean species are associated with three species groups: the Indo-Pacific A. pallidicornis group, the Pantropical A. abruptus group, and the Madagascan A. stuckenbergi group.
Similar Taxa
