Akdeniz türleri üzerine bazı taksonomik notlarla birlikte, Türkiye kıyılarındaki Granulina (Mollusca: Gastropoda: Neogastropoda) genusunun durumu

Türkiye kıyılarından dört Granulina türü bilinmektedir: G. marginata (Bivona, 1832), G. occulta (Monterosato, 1869), G. boucheti Gofas, 1992 ve G. melitensis Smriglio, Mariottini & Rufini, 1998. Bu çalışmada, G. marginata/G. boucheti ve G. occulta/G. melitensis grubu olmak üzere, iki «morfolojik benzerlik» çerçevesinde türlerin kabuk morfolojisindeki büyük değişkenlik karşılaştırmalı olarak incelenmiş ve G. boucheti ile G. melitensis türlerinin de ilave edilmesiyle, araştırma sahasından bilinen tür sayısı dörde yükselmiştir. Granulina guttula La Perna, 1999 türünün, Erato guttula Sowerby, 1832 den farklı bir tür olduğu belirlenmiş ve ilk türün geçerliliği korunmuştur. Granulina gubbiolii Smriglio & Mariottini, 1999 ise Granulina minusculina (Locard, 1897)’nın genç sinonimi olarak ele alınmıştır.

The genus Granulina (Mollusca: Gastropoda: Neogastropoda) from the Turkish coasts with taxonomical notes on some Mediterranean species

In the present study four Granulina species we recognized from the Turkish coasts: G. marginata (Bivona, 1832), G. occulta (Monterosato, 1869),G. boucheti Gofas, 1992 and G. melitensis Smriglio, Mariottini & Rufini, 1998. The high variability of the shell morphology is studied and «morphologicaffinities» are comparatively analized, and two different complex of species are here recognised: the G. marginata/G. boucheti complex and theG. occulta/G. melitensis complex. Meanwhile, with our records the number of the species known from the research area has been increased to four with theaddtion of G. boucheti and G. melitensis. The name Granulina guttula La Perna, 1999 is restored, being considered as not preoccuped by Erato guttulaSowerby, 1832. Granulina gubbiolii Smriglio & Mariottini, 1999 is here recognised as a junior synonym of Granulina minusculina (Locard, 1897).
