‘ PARADAKKAMYS ’ OUAICHI (JAEGER, 1977B)

The holotype and single specimen (KO-8, housed at SGM) of ‘ Paradakkamys ’ ouaichi is a left M1 from the Late Miocene site of Khendek-el-Ouaich, Morocco. As for ‘ P. ’ seboui, this species was transferred from Myocricetodon to Dakkamys ( Lindsay, 1988) and then to Paradakkamys ( Tong & Jaeger, 1993) . None of these re-assignments are supported by the cladistic analysis conducted below, which suggests that ‘ P. ’ ouaichi is more closely related to Myocricetodon cherifiensis than to Dakkamys zaiani and Paradakkamys chinjiensis .

Some of the differences between ‘ Paradakkamys ’ ouaichi and AJ7 are the presence of strongly alternating cusps, a well-developed longitudinal crest, and the absence of a ridge anterior to the anterocone.
