Family FOLLICUCULLIDAE Ormiston & Babcock, 1979
Cariver Kozur, 1993
Cariver Kozur, 1993: 108.
TYPE SPECIES. — Follicucullus orthogonus Caridroit & De Wever, 1984 ( Caridroit & De Wever 1984: 642, pl. 1, figs 23-29).
AGE AND LOCATION OF TYPE MATERIAL. — Upper Permian, Kamigori, Japan.
TAXON CODE. — 029.
STATUS. — Junior synonym of Follicucullus (by Takemura et al. 1999: 758).
DIAGNOSIS. — “Apical horn long, unsegmented. Pseudothorax large, inflated. Pseudoabdomen, partly also posterior part of pseudothorax ventralwards curved. Aperture oval, situated on the ventral side, perpendicularly or nearly perpendicularly to the test axis. A ventral sinus on the pseudothorax is always present, a dorsal sinus may be additionally present.” ( Kozur 1993: 108).
REMARKS
Cariver is considered a junior synonym of Follicucullus because the type species falls well within the original diagnosis of Follicucullus . Kozur (1993) mentions that there are some species that appear transitional between Cariver and the narrower definition of Follicucullus sensu Kozur & Mostler (1989) , such as Follicucullus ? charveti Caridroit & De Wever, 1984, which supports our opinion that the distinction between these genera is not a clear one and the differences between them should be considered at species level.
