NEW AND ADDITIONAL RECORDS OF THE SPONGE SHRIMP GENUS TYPTON COSTA, 1844 (DECAPODA: PALAEMONIDAE) FROM THE BRAZILIAN COAST

The present study deals with Brazilian material of four sponge-dwelling species of the pontoniine shrimp genus Typton Costa, 1844: T. distinctus Chace, 1972, T. fapespae Almeida, Anker & Mantelatto, 2014, T. prionurus Holthuis, 1951, and T. vulcanus Holthuis, 1951. Typton distinctus and T. fapespae are recorded for the first time from Rio de Janeiro, representing a significant southward range extension for the former species (previously known only from Pernambuco) and a slight northward extension for the latter species (previously known only from São Paulo). Typton prionurus and T. vulcanus are recorded for the first time from Bahia. The former species was previously known from Brazil based on a single questionable record from the coast of Pará, whereas the latter species is recorded from Brazil and the southwestern Atlantic for the first time. Illustrations are provided for T. prionurus and T. vulcanus.
