Pseudorientalia natolica (Küster, 1852)’nın Yeniden Tanımlanması ve Aynı Lokalitede Yaşayan (Bursa) Falsibelgrandiella bunarica (Radoman, 1973) Türünün Ortadan Kaybolması Üzerine Bir Tartışma

Öz

Bu çalışma kapsamında, Pseudorientalia natolica tip lokalitesinde tekrar tespit edilmiş ve topotiplerinin konkolojik ve anatomik karakterleri çalışılmıştır. Fakat aynı lokalitede birlikte yaşayan Falsibelgrandiella bunarica bireylerine rastlanmamıştır. Ayrıca F. bunarica’nın yok oluş veya kayboluş sebepleri de tartışılmıştır.

With this study, Pseudorientalia natolica was re-found from type locality and conchological and anatomical characters of the topotypes have been studied. But there was no specimen of the Falsibelgrandiella bunarica which is living together recorded in the same locality. Also, the reasons of the existence or disappearance of the F. bunarica is discussed.
