Hedbergella murphyi is the type species of Meridionalla El-Nakhal, 1982 said to be a junior synonym of Hedbergella by Petrizzio and Premoli Silva(2000) because of the lack of costellae. If now H. murphyi is said to belong to the genus Muricohedbergella, it seems there could be problem of priority?

Best regards,
