Taxonomy Comments: The circumscription of the "latiusculum entity" follows Thomson, Mickel, & Mehltreter (2008) in excluding Old World material included by many earlier authors. The relationship of the ‘latiusculum’ and ‘pseudocaudatum’ entities is discussed in detail by Speer & Hilu (1999) and Speer, Werth, & Hilu (1999).
