Calomys (Bensonomys) eliasi
Taxonomy
Peromyscus eliasi was named by Hibbard (1937) [also said to be 1938]. Its type locality is Rexroad KU Locality 2, which is in a Blancan terrestrial horizon in the Rexroad Formation of Kansas.
It was synonymized subjectively with Bensonomys arizonae by Hibbard (1950); it was recombined as Calomys (Bensonomys) eliasi by Baskin (1978); it was recombined as Calomys eliasi by Czaplewski (1987); it was recombined as Bensonomys eliasi by Hibbard (1956), Kurten and Anderson (1980), Martin et al. (2002).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Hibbard 1956 | This species was first taken from the Rexroad formation at Locality
2, Meade County, Kansas. Later collecting at Localities 2 and 3 has furnished additional specimens, and these have been compared with the holotype and the paratype of Bensonomys arizonae. It was found that B. eliasi is a valid species. In both young adult and adult specimens tbe lower incisor of B. eliasi has a greater transverse width than the lower incisor of B. arizonae. m1 in B. eliasi is more rectangular than the m1 of B. arizonae, which tends to be triangular , with the apex of the triangle at the anteroconid. The reëntrant valleys of m1. and m2 in B. eliasi are broader than those of B. arizonae. The holotype of Peromyscus eliasi (KUMVP 3941) is a fragmentary left lower jaw, with m1-m3, of a very old adult. The teeth are worn down to their bases, and only the outlines of a few of the reentrant angles and cusps remain. |
