title: A new genus of freshwater crab of the tribe Kingsleyini Bott, 1970 (Crustacea: Decapoda: Brachyura: Pseudothelphusidae) with description of a new species from Mato Grosso, Brazil.
abstract: A new genus and species of freshwater crab, Melothelphusa apiaka n. gen., n. sp., from Mato Grosso, Central Brazil is described and illustrated. Brasiliothelphusa dardanelosensis Magalhães & Türkay, 2010, is assigned to the new genus Melothelphusa. Therefore, the genus Brasiliothelphusa Magalhães & Türkay, 1986, is restricted to its type species B. tapajoense Magalhães & Türkay, 1986. The new taxa can be easily separated from their close relatives by a suite of morphological characters from the first gonopod.
