Extension of geographical range and first record of <i>Trizocarcinus</i> Rathbun, 1914 (Brachyura: Euryplacidae) from the Western Tropical South Atlantic

Here, we report the first occurrence of Trizocarcinus Rathbun, 1914 (Brachyura: Euryplacidae) from the South Atlantic (Brazil). Trizocarcinus tacitus Chace, 1940 was collected in the upper continental slope of the Potiguar Basin, northeastern Brazil. The new record expands by 3000 km the southern distribution of the species in the Western Atlantic.
