Vasseuromys is a species‐rich genus of small‐ to medium‐sized glirids
spanning the latest Oligocene to late Miocene of Europe and western Asia.
Despite extensive discoveries over the past 50 years, little phylogenetic
work has been done on Vasseuromys. This study presents the first
phylogenetic analysis of the genus that includes all the described species
and a new taxon Vasseuromys tectus sp. nov. from the late Miocene of
eastern Europe, providing the first insights into the evolutionary
relationships within the clade. Results suggest that the genus is clearly
paraphyletic. Two strongly supported genus‐level clades are recognized
within ‘Vasseuromys’: a restricted Vasseuromys clade (containing the three
species, V. pannonicus, V. rugosus and V. tectus) and the Glirulus clade
that includes ‘Vasseuromys’ duplex. The remaining ‘Vasseuromys’ species
are found to constitute a set of paraphyletic taxa, with the polyphyletic
‘Ramys’ nested within it. The genus Gliruloides is synonymized with
Glirulus. Vasseuromys tectus sp. nov. is the most derived member of the
genus in having a greater number of cheek teeth ridges including
constantly present anterotrope, centrotrope, second prototrope on M1–2,
third metatrope on M2, two to three posterotropids on p4 and strong
ectolophids on lower molars. The results of the study confirm a European
origin for Vasseuromys while suggesting that the late Miocene species of
the genus dispersed from the east in the early Turolian.
Sinitsa, Nesin, Data Matrix for Gliridae generaA total of 58 dental
characters were scored with all characters equally weighted and treated as
unordered. Skeletal characters were not included since cranial and
postcranial remains are only known for three extinct taxa, namely G.
majori (Vianey-Liaud 1989), V. pannonicus and putative Vasseuromys from
St.-Gérand-le-Puy (Vianey-Liaud 1985). The best-known basal glirid
Gliravus majori (Stehlin & Schaub, 1951) and primitive leithiine
Oligodyromys planus Bahlo, 1975 from the late Rupelian of Heimersheim
serving as the outgroup. Apart from V. tectus sp. now. from the late
Miocene (late Tortonian) of Palievo in Ukraine the ingroup taxa include
all the ten currently recognized species of Vasseuromys. These are: V.
autolensis (Cuenca Bescos, 1985) from the early Miocene (early Aquitanian)
of Autol 1, Spain; V. bacchius (Martínez-Salanova, 1987) from the early
Miocene (late Aquitanian) of Fuenmayor 2, Spain; V. bergasensis
Ruiz-Sánchez et al., 2014 from the latest Oligocene (late Chattian) of
Bergasa, Spain; V. cristinae Ruiz-Sánchez et al., 2012a from the early
Miocene (late Burdigalian) of Pico del Fraile 2, Spain; V. duplex Ünay,
1994 from the early Miocene (late Aquitanian) of Harami 1, Turkey; V.
elegans Wu, 1993 from the early Miocene (middle Burdigalian) of
Stubersheim 3, Germany; V. pannonicus from the late Miocene (late
Tortonian) of Kohfidisch, Austria; V. priscus de Bonis, 1973 from the
early Miocene (early Aquitanian) of Moissac 1, France; V. rambliensis
Ruiz-Sánchez et al., 2012b from the early Miocene (middle Burdigalian) of
Pico del Fraile 1, Spain; and the type species, V. rugosus Baudelot
& de Bonis, 1966 from the early Miocene (early Aquitanian) of
Laugnac, France. The type species of Ramys, R. multicrestatus (de Bruijn,
1966b) from the early Tortonian of Pedregueras 2A and R. perezi
Álvarez-Sierra, 1986 from Ampudia 9 were also included in the analysis to
test the monophyly of the concerned genus. Ramys gipanensis Nesin, 2004, a
poorly-known species from the middle Tortonian of Mikhailovka 1 was not
included in the analysis to minimize the impact of missing data on the
present analysis. Microdyromys complicatus de Bruijn, 1966a from the late
Langhian of Armantes 7/E and Microdyromys koenigswaldi de Bruijn, 1966a
from the early Langhian of Valdemoros 3B/E serve as representatives of
basal Glirinae, whereas Peridyromys murinus (Pomel, 1853) from the late
Aquitanian of Langy/F serves as representative of basal Seleviniini.
Gliruloides zhoui Wu et al., 2016, a putative Vasseuromys-related glirid
from the late Oligocene of Tieersihabahe and Saerduoyila assemblages of
northern Junggar Basin was included in the analysis to clarify its
systematics. The ingroup also includes extant species of Leithiinae
(Dryomys nitedula, Myomimus roachi) and Glirinae (Grirulus japonicus) to
assess the position of Vasseuromys and some other fossil taxa
(Gliruloides, Ramys) with respect to these potentially related
genera.Sinitsa_Nesin_Data_Matrix_for
