Misikella is an extinct genus of conodonts.^[2]

Two species were named as type species for the genus in separate publications by the same authors in the same year (1974). The first paper named Misikella longidentata, while the second named Misikella posthernsteini. Most species assigned to Misikella have a Norian-Rhaetian distribution and a bimembrate conodont apparatus, including M. posthernsteini. On the other hand, M. longidentata has a Carnian-Norian distribution and a tetramembrate apparatus. Fåhræus & Ryley (1989) retained the name Misikella for only M. longidentata, placing the rest of the species into the new genus Axiothea.^[3] However, other conodont specialists utilize the name Misikella primarily in the context of M. posthernsteini and other bimembrate species, rather than M. longidentata.^[2] Uniquely, M. posthernsteini is known from the Hettangian of Japan,^[4] suggesting that conodonts underwent extinction debt and then were outcompeted by other organisms.
