The two Bathynectes species occurring in the Mediterranean, B. longipes (Risso, 1816) and B. maravigna (Prestandrea, 1839), are seldom found inhabitants of deeper waters; the first species ranging from 20 to 226 m depth, the second from 60 to 800 m (Abello et al. 2001, Garcia Raso 1984, Stevcib 1990). In the past, the northernmost records of B. longipes were from the Kvarner Gulf (e. g. Lorenz 1863) and a few other locations in the middle Adriatic (e. g. Adensamer 1898), and those of B. maravig­ na in the southern Adriatic Sea (Pesta 1918, Stevcib 1990, Froglia 2010). Occurrence and ecological data have been summarized recently by Milisib (2008) who also published a colour photo. In the northern Adriatic sector, representing a distinct biogeographic region with its
