Copemys (sensu Lindsay, 2008, whose terminology differs from Reig's  in part) differs from Postcopemys in having molars with alternation of the labial and lingual cusps incomplete, protolophules (= protolophule and paraloph) on Ml and M2 weakly developed, protolophule II (= paraloph) not aligned with the anterior arm of the hypocone
, entolophulids (= entolophids) of ml and m2 weakly developed, not aligned with the posterior arm of the protoconid.
Based on the size, the less elongated shape of this specimen, the presence of low posterior spurs connecting the protocone-hypocone and paracone-metacone pairs and the more accentuated asymmetry in the position of metacone and hypocone
in the M1 of Debruijnimys from La Bullana 2B, we distinguish this tooth from D.
The results indicate a high frequency of shovel-shaped incisors, a low frequency of the Carabelli cusp, a high proportion of hypocone
reduction, variable frequency of sixth cusp, a high frequency percentage of the seventh cusp, high percentages of the upper layered fold and high frequencies of the protostylid.
The greatest amount of hypocone
reduction (0+1 grades) is shown in the American Arctic (29%) and Western Eurasia (25%).
The M2 lacks a talon and hypocone
, and the postprotocrista runs from the protocone to the base of the metacone.
It can be distinguished from the other Pseudoloris species by its medium size, high and thick paracristid and absence of a distinct paraconid in the lower molars, large hypoconulid in the [M.sub.3], well-developed protocone in the [P.sup.3] and [P.sup.4], small hypocone
in the upper molars, and especially for its particular lower incisors, with a large, buccolingually enlarged crown and a thick root.
Among other characters, its long mesoloph reaches the labial border but is not connected to the hypocone
. A long mesoloph is common in Rhodanomys transiens from Bergasa and R.
The median valley is filled with matrix and separates the protocone and hypocone
. The M1 is relatively well preserved and in a late wear.
It is also higher than the hypocone
which is slightly damaged at the apex.
Metalophule connected behind the hypocone
. Posterosinus small.
is elongated with well-developed hypoconal groove.
In the genus Helladotherium, molars are provided with an enamel island in the hypocone
