REMARKS

Two specimens of the species were recovered, that can be easily distinguished from other species of Melongena mainly by having a spiral sculpture of spiral angular cords separated by deep furrows (of variable width), an elongated slightly pyriform shape, and has a single row of shoulder spines.

Melongena lainei has been found in the neighbouring location of Agapi in the Aquitanian of the Mesohellenic Basin ( Harzhauser & Kowalke 2001). Melongena lainei semseyiana (Erdös, 1900) is found in the late Oligocene of the Mesohellenic Basin; it is considered to represent a chrono-subspecies ( Harzhauser 2004) and is treated as belonging to the M. semseyana lineage by Landau et al. (2013). In the middle Miocene of the Proto-Mediterranean ( Turkey), this melongenid is replaced by M. jaapi Landau, Harzhauser, İslamoğlu & Silva, 2013, a species easily distinguished from M. lainei in having shorter spires and a more inflated last whorl.

Modern representatives of Melongena live in the intertidal zone (some can be found up to depths of 30 m) of the Caribbean, the Panama, and Indo-Pacific bio-provinces and are predators mainly on bivalves (including burrowing species) ( Lozouet & Londeix 2014b). In the fossil record, M. lainei is present in brackish-water paleocommunities in the Proto-Mediterranean during the Aquitanian and the Burdigalian ( Harzhauser & Kowalke 2001; Lozouet et al. 2001).
