Mangelia brusinae ( Van Aartsen & Fehr-de Wal 1978)

( Fig. 3 )

Mangiliella brusinae Van Aartsen & Fehr-de Wal 1978: 102–103 , fig. 3

Materials: 20.09.2005, Finike Bay , sandy mud, 25 m, 1 sh. ( ESFM-GAS/2005 /-99) ; 26.06.2013, Bosphorus , muddy sand with shell fragments, 25 m, 1 sh. ( ESFM-GAS/2013-44 ) ; 19.10.2017, Asa Bay (Aegean Sea ), sandy mud with P. oceanica , 24 m, 1 sh. ( ESFM-GAS/2017-82 ) .

Remarks: The species has an ovate biconic or a relatively longer shell with multispiral protoconch. The sculpture on the teleoconch whorls consists of axial ribs only (on the body whorl 8–9 ribs), being a bit narrower and shouldered to the suture. No spiral sculpture (completely smooth). Aperture narrow, with posterior sinus and well developed varix on the outer lip. White spiral bands on the light brown background are characteristic. On the body whorl their number varies between 6–8, and the one below the suture is wider. Differences between it and similar Mangelia species were described by Van Aartsen & Fehr-de Wal (1978). Height of the shell up to 6.5 mm.

Distribution: Mediterranean Sea ( Van Aartsen & Fehr-de Wal 1978). Turkish coasts: Levantine Sea and Sea of Marmara (Özt̹rk et al. 2014), Aegean Sea ( GBIF 2020) and Bosphorus (present study).
