New records of two uncommon species, calappa tuerkayana pastore, 1995 (Decapoda, calappidae) and parasquilla ferrussaci (roux, 1828) (stomatopoda, parasquillidae), from the strait of sicily (central mediterranean sea)

The shamefaced crab Calappa tuerkayana Pastore, 1995 and the mantis shrimp Parasquilla ferussaci (Roux, 1828) are two crustacean species rarely reported in the Mediterranean Sea. In December 2018, two specimens of C. tuerkayana and one specimen of P. ferussaci were collected on a soft bottom at about 132 and 145 m depth during a trawl survey off Mazara del Vallo harbour (Strait of Sicily). This note reports the northernmost record of C. tuerkayana in the Strait of Sicily and confirms the occurrence of P. ferussaci in the same area. An update of the spatial distribution of these crustacean species in the Mediterranean Sea is also presented.
