Allosergestes sargassi (Ortmann, 1893) ( Figure 3 )

Material examined: Six specimens (1 ♂, 5 ♀♀); 21–31 mm TL; Stations 1 (40.236°N, 25.402°E), 2 (40.276°N, 25.606°E), and 5 (40.366°N, 26.108°E).

Description: A. sargassi was identified by the following diagnostic characters according to Farfante and Kensley (1997): carapace has red chromatophores. Rostrum is short and triangular. Supraorbital spine, dermal photophore, and organ of Pesta are absent. Maxilliped 3 is longer than pereopod 3. Comb-like spinations are absent on the dactyl and distal half of propodus of maxilliped 3.

Distribution: A. sargassi is a cosmopolitan species living in the Mediterranean sea and Atlantic from 45°N to 34°S ( Crosnier and Forest, 1973; Farfante and Kensley, 1997). This species is also recorded from South Africa ( Kensley, 2006). The only record from the Aegean Sea was documented by Koukouras (2000). The current study reports the species for the first time from the Turkish seas.
