Taxonomy of the neotropical freshwater crab family trichodactylidae, IV. The genera Dilocarcinus and Poppiana (Crustacea, Decapoda, Trichodactylidae)

Abstract

The genera Dilocarcinus and Poppiana (tribe Dilocarcinini) of the freshwater crab family Trichodactylidae are revised. These genera each include three species, i.e.: Dilocarcinus septemdentatus (Herbst 1783), D. pagei Stimpson 1861, and D. truncatus Rodríguez 1992; Poppiana dentata (Randall 1840), P. argentiniana (Rathbun 1905), and P. bulbifer (Rodriguez 1992). The taxonomic status of all species is discussed and a short diagnosis for each is provided. Lectotypes for P. argentiniana (♂ in MNHN-collection) and P. dentata (♂ in ANSP-collection) are designated. A complete list of the material examined, and maps showing the geographic distribution, are given. © E. Schweizerbart'sche Verlagsbuchhandlung (Nägele u. Obermiller), 2008.
