Abstract
The name Flexopecten glaber ponticus (Bucquoy, Dautzenberg & Dollfus, 1889) is generally used for the only Pectinidae representative inhabiting the Black Sea. It is registered in the Red Book of the Republic of Crimea as endemic subspecies reducing in amount. F. glaber ponticus is listed in WoRMS MolluscaBase as the only accepted subspecies of Flexopecten glaber (Linnaeus, 1758). In the past its taxonomic status has been changed from a geographic variety to valid species. The purpose of this study is to establish its correct taxonomic status. The study is based on a comparative analysis of conchological features of Flexopecten glaber and F. glaber ponticus in relation with the brief natural history of population in the Black Sea. Sampling was performed by snorkel equipment in Kazach’ya Bay (Black Sea, Crimea, Sevastopol) at 2–6 m depths. A total of 100 scallop specimens were sampled in September 2017. To assure a better understanding in a broader context those results are compared with the previously published morphological data based on the analysis of a large amount of material from the Black Sea and the Mediterranean Sea – Marmara Sea regions. Comparative analysis of conchological features of F. glaber ponticus from the Black Sea with F. glaber from the Mediterranean region has not revealed any distinct differences between them. Thus, there are no evidenced data for the diagnosis of F. glaber ponticus as a subspecies. Species F. glaber appeared in the Black Sea not earlier than 7,000 years ago and formed a well developed population less than 3,000 years ago. We have to conclude that the specified divergence period is not long enough to form a subspecies. As a result of the present survey the subspecific status of F. glaber ponticus is not retained and the name is placed in synonymy of the parent species Flexopecten glaber.
