- Redefinition of Amphiope neuparthi de Loriol, 1905 (Echinoidea, Astriclypeidae) from the early-middle Miocene of AngolaPublication . Pereira, Pedro; Stara, PaoloPending a full revision of the genus Amphiope, necessary as result of several recent findings in various peri-Mediterranean localities by a network of research groups, here are redefined, by an analytical approach combining morphometric and structural (analysis of plate patterns and X-ray images) data, the specific characters of the fossil species Amphiope neuparthi de Loriol, 1905, from the upper Burdigalian-Langhian of Angola (Central-West Africa). A. neuparthi is characterized by large, subcircular to wide ovoidal lunules, and a peculiar posterior deep marginal notch. Moreover, it is characterized by an internal structure with a wide central hollow and peripheral ballast system, which becomes denser towards the margin.
