Foraminifera note details
ICZN article 18.104.22.168. stipulates: "A compound genus-group name ending in the suffix -ites, -oides, -ides, -odes, or -istes is to be treated as masculine unless its author, when establishing the name, stated that it had another gender or treated it as such by combining it with an adjectival species-group name in another gender form." Brotzen (1942) did not give any indication about the gender of Anomalinoides. Therefore the genus is treated as masculine.
