Mangelia stosiciana Brusina 1869

( Fig. 12 )

Materials: 07.03.2003, Çandarlı Bay, Aegean Sea , P. oceanica + sand, 46 m, 1 spm ( ESFM-GAS/2003-73 ) ; 17.06.2013, Sea of Marmara , sandy mud with shell fragments, 50 m, 2 spm ( ESFM-GAS/2013-56 ) ; 11.04.2014, Güllük Bay, Aegean Sea , muddy sand, 45 m, 2 spm ( ESFM-GAS/2014-39 ) ; 06.04.2017, Eski Foça, Aegean Sea , P. oceanica , 8 m, 1 spm ( ESFM-GAS/2017-90 ) .

Remarks: The shell has a multispiral protoconch and on teleoconch whorls has a sculpture of orthocline axial ribs (8–10 ribs on the body whorl) and spiral cords. The thinner spiral cords are many in number and 5–6 thin striae are located between two stronger cords. Posterior sinus and labial varix are well developed. The species can be distinguished from the similar M. unifasciata by its protoconch with has a greater number of whorls and its stronger spiral cords.

Although Scarponi & Della Bella (2010:83) comment that the protoconch of M. stosiciana is similar to that of Glabrocythara locklini Fargo and that more anatomical studies should be performed to evaluate the generic affinities of these species, M. stosiciana is considered within the genus Mangelia (WoRMS Editorial Board 2020) .

Distribution: Eastern Atlantic Ocean and Mediterranean Sea ( Gofas et al. 2011). Turkish coasts: Levantine Sea, Aegean Sea and Sea of Marmara (Özt̹rk et al. 2014).
