Diagnosis Test lenticular, biconvex, trochospiral, about three and a half whorls visible on the spiral side, gradually enlarging chambers broad, low, and crescentic and sutures slightly curved, strongly oblique and weakly depressed, on the umbilical side only the five chambers of the final whorl visible and sutures nearly radial, periphery rounded; wall calcareous, very finely perforate, surface smooth; interiomarginal primary aperture midway betweem umbilicus and periphery on the umbilical side, short slitlike supplementary openings on the spiral side at the midpoint of the chambers are near and parallel to the spiral suture at the junction with the intercameral suture, additional hooklike supplementary slits at the posterior margin of each chamber on the umbilical side, perpendicular to the suture and then curving forward, reflecting the position of the internal tooth plate that extends vertically through the chamber and attaches at the supplementary opening on the spiral side. Pliocene to Holocene; Japan; Caribbean; Netherlands. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
Grammatical gender Initially given with the type species Pseudoeponides japonica indicating a feminine gender (published in Japanese), it was corrected the following year to P. japonicus by Uchio (1951, p. 38, in English) in a far more detailed description of the genus and of the type species. Eponides being masculine, it seems more logical to follow Uchio (1951). [details]
Taxonomic remark Junior synonym in opinion of Hofker (1958) and Schweizer et al. (2011) but discounted by Hayward et al. (2021) [details]
Taxonomy Genetically species of this genus fall within the Ammoniidae clade and the genus has therefore been transferred to that family. [details]
