Ratcliffe, B.C. 1976. A revision of the genus Strategus. Bulletin of the University of Nebraska State Museum 10(3): 93-204.

Abstract

The New World genus Strategus Kirby is here defined and revised for the first time. Eight species are described as new: S. atlanticus, S. caymani, S. craigi, S. hipposiderus, S. howdeni, S. longichomperus, S. symphenax, and S. tarquinius; 12 new junior synonyms are established (including the rejection of six previously valid species); one species is raised from synonymy; and two new replacement names are proposed. Strategus now contains one fossil species and 31 valid extant species. A key to the males and females of all the species is provided for the first time. All taxa are described or redescribed and illustrated by habitus figures and drawings of the male genitalia. Biologies are discussed when data are available. Extensive distributional data and locality record dot maps are presented as well as a zoogeographical analysis of the genus. Lastly, a computer-assisted cladistic reconstruction of the presumed phylogeny of the genus is provided.
