Tiburonella viscana is a benthic amphipod commonly used for ecotoxicological tests, assessment of contamination in marine sediments and environmental monitoring in Brazilian waters (see among others, Abessa et al. 1998; Abessa & Sousa 2003; Melo & Nipper 2007; Torres et al. 2009).
Tiburonella viscana is widely distributed along western and eastern coasts of the American continent. In the Pacific Ocean, it has been reported from La Jolla (California, USA) to Puerto Utria (Colombia), living in coarse sand between 3–127 m depth (Thomas & Barnard 1983). It is also present in the Caribbean Sea (Belize, Aruba, Grenadines Islands, Costa Rica and Venezuela) where it has been found in patches of sand, coarse coral sand, coral reefs and sponges, between 1–41 m depth (Thomas & Barnard 1983; Atienza & Martín 2001; Ortiz et al. 2007). In the Atlantic Ocean, it was recorded in Brazil, off the coasts of Bahia and Sãn Pablo states (from 23.5°S to 25.03°S), inhabiting principally patches of muddy sand, close to banks of the seagrass Halodule sp., between intertidal to 4 m depth (Wakabara et al. 1991; Melo & Nipper 2007).
The distribution of Tiburonella viscana is herein extended in the South-West Atlantic Ocean, where it is reported for the first time from the Argentine Sea. The species was collected at two stations off San Borombón Bay (Buenos Aires province), near Río de la Plata, at 16–17 m depth (see Fig. 1). The bottom at both stations was mainly composed of sand and shell, and the presence of abundant molluscs (gastropods and bivalves) and the sea cucumber Thandarum hernandezi Martinez & Brogger, 2012 (see Martinez & Brogger 2012).
