Discussion Diaphus draconis is an inconspicuous small species reaching about 2 mm in length in the Moroccan localities. It can be easily confused with small specimens of larger species (see extensive discussion in Carnevale & Schwarzhans, 2022). It may be recognized best by its 4–6 widely spaced strong denticles along the ventral rim. Diaphus draconis was originally described from the Serravallian/Tortonian of Gabon ( Schwarzhans, 2013c) and also recorded from the Tortonian of New Zealand ( Schwarzhans, 2019a), indicating a wide geographic distribution. Specimens from the latest Messinian Lago Mare phase of Italy were only tentatively allocated ( Carnevale & Schwarzhans, 2022). In the Rharb Basin of Morocco, the best preserved specimens were obtained from the basal levels of Kef Nsour, which are supposed to be Messinian in age. Specimens from the basal level of Sidi Mohammed ech Chleuh are slightly leached, possibly indicating an origin from reworked Messinian strata below. Tere are no positive records from the Zanclean.
