)
SYNONYMY. — See Vianey-Liaud
et al.
(1995).
HOLOTYPE
. — Left M/2, no. 96182, Lyon 1 University.
TYPE LOCALITY
. — Coderet (Allier,
France
),
MP
30.
DIAGNOSIS. — “
Gliravus
with teeth significantly larger than those of
G. majori
Stehlin & Schaub, 1951
, and
G. tenuis
, Bahlo, 1975
, smaller than those of
G. bravoi
Hugueney
et al.
, 1985
, and size close to that of
G. daamsi
, Bosma & de Bruijn, 1982
. Differs from the other
Gliravus
species by the absence of mesoconid and the reduced mesolophid; mesolophid occasionally connected to the hypoconid. Centrolophs generally reduced, and very low when present” (Vianey-liaud 1994: 133, translated from French).
MATERIAL
AND
MEASUREMENTS (in mm). — Two M1-2:
SPV
192: 1.23 × 1.50,
SPV
193: 1.12-1.40; three m1-2:
SPV
194: 1.24 × 1.29,
SPV
195: 1.28 × 1.39,
SPV
196: 1.22 × 1.39.
DESCRIPTION
Teeth size and morphological characters fall into the variations of those of
Gliravus bruijni
Hugueney,
1967, as described from different localities where the species occurs (e.g.,
Hugueney 1967
; Vianey- Liaud 1994; Vianey-Liaud
et al.
1995).
M1-2 pattern is simple, with a single centroloph, and the lingual ends of anteroloph and posteroloph swollen and well separated from the protocone. On m1-2, the mesoconid is absent.
