Remarks on some Eurasian pliocervines: Characteristics, evolution, and relationships with the tribe Cervini

In order to define the ancestors of the Eurasian genera Axis and Rusa, the representatives of the tribe Pliocervini have been reviewed, with the exclusion of the genus Pliocervus. The fossil remains referred to Pliocervini stored in the Palaeontological Museum of Mechnikov Odessa National University and studied by Khomenko [Khomenko, I., 1913. Meotian fauna of v. Tarakliya of Bendery district. Annuaire geologique et mineralogique de la Russie. 1. The ancestors of modern and fossil Cervinae. 2. Giraffidae and Cavicornia 15, 107-132 (in Russian)] are reappraised: these remains are attributed to Cervavitus novorossiae (Khomenko, 1913). The fossil deer collected from the locality of Novoelizavetovka (Odessa region, Ukraine) and observed in the same Museum of the Odessa National University, is referred to Cervavitus variabilis (Alexeev, 1915). The fossil material from Shanxi and Honan provinces (China), described by Zdansky [Zdansky, O., 1925. Fossil Hirsche Chinas. Palaeontologia Sinica C 2, 1-94] and Teilhard de Chardin and Trassaert [Teilhard de Chardin, P., Trassaert, M., 1937. The Pliocene Camelidae, Giraffidae and Cervidae of southeastern Shansi.] is referred to Cervavitus shanxius Dong and Hu, 1994. The phylogenetic relationships between Pliocervini from China and the European ones are investigated on the basis of the morphological, biochronological and paleogeographical data. These elements and the suggestions of the more recent genetical and biometrical data may indicate that the origin of the two genera Axis and Rusa could be recognized into the Chinese pliocervines.
