Systematic studies are scarce and the best known records are about rodents and some species of bats. For that reason, the main purpose of this work is to present a list of the mammalian species of the province. The sources of information are unpublished data of the authors, a revision of the lists of references of collections from national and regional museums, and bibliographic research. The sequence of orders, families, and the scientific nomenclature follows that of Monjeau et al. (1994) and Galliari et al. (1996), except for the cases commented in the footnotes. We establish a list of 71 species, grouped in 54 genus, and 20 families. The most numerous order is Rodentia, with 25 species, grouped in 17 genus and 6 families. Quiroptera has 15 species, grouped in 10 genus and 3 families. The list includes 5 exotic species. RESUMEN: Lista comentada de las especies de mamíferos de Córdoba. El conocimiento sobre los mamíferos presentes en la Provincia de Córdoba se caracteriza por ser fragmentario e incompleto. Los estudios sistemáticos son escasos y los registros más conocidos corresponden a roedores y a algunas especies de murciélagos. En razón de ello, el objetivo de este trabajo es presentar una lista de las especies de mamíferos de la Provincia. La información se relevó a partir de datos no publicados de los autores, revisión de listados de colecciones de referencia de museos nacionales y regionales, y a partir de revisiones bibliográficas. La secuencia de órdenes y familias y la nomenclatura científica, sigue la taxonomía utilizada por Monjeau et al. (1994) y Galliari et al. (1996), excepto en los casos aclarados a pie de página. Se establece un registro de 71 especies, agrupadas en 54 géneros y 20 familias. El orden más numeroso es Rodentia, con 25 especies, agrupadas en 17 géneros y 6 familias. Le sigue en segundo término el orden Quiroptera, con 15 especies, 10 géneros y 3 familias. Se incluyen 5 especies exóticas. Key words: mammals, Córdoba Province, annotated checklist, taxonomy. Palabras clave: mamíferos, Provincia de Córdoba, lista comentada, taxonomía. INTRODUCTION As a result of its geographic position, geomorphologic processes, climatic conditions, and its vegetational and faunal evolutionary processes, the Córdoba Province presents a remarkable habitat variability. In this region, Guayanic-Brasilic and Andean-Patagonic faunistic components converge (Ringuelet, 1961) Recibido 18 junio 1996. Aceptado 28 julio 1997. (Fig. 1). In spite of their species richness (Bucher y Abalos, 1979; Luti et al., 1979), wild mammals have been scarcely studied in the province; except for sigmodontine rodents and certain groups of bats (Crespo et al., 1961; Polop et al., 1985; Polop, 1989, 1991, 1996; Gutierrez et al., 1991, 1996; Tiranti, 1996). This lack of information, new or previously unknown species for this region and changes 130 Fig. 1. M. Morando and J.J. Polop Neotropic Subregions in Córdoba Province: a-Guayanic-Brasilic Subregion; b-Andean-Patagonic Subregion. in the nomenclature are the basis of this work, therefore the aim of the present paper is to show the mastofaunistic diversity of Córdoba. The information was collected from captures and field observations since 1982, as well as from the examination of mastozoological collections of national museums: Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” and Museo La Plata; and regional museums: Museo Regional Morteros, Museo Independencia and Museo Particular Rocsen. A bibliographic review was done (Yepes, 1929; Cabrera, 1958, 1961; Cabrera and Yepes, 1960; Bucher and Abalos, 1979; Rosacher and Miatello, 1990; Redford and Eisenberg, 1992; Bárquez et al., 1993; Gardner, 1993a, 1993b; Koopman, 1993; Musser and Carleton, 1993; Woods, 1993; Chebez, 1994), and unpublished information was gathered from specialists. To show the results of this paper we follow the nomenclature and the scheme used by Monjeau et al. (1994) and Galliari et al. (1996). Since the systematic lists are shortlived at present, certainly future distributional, taxonomic and field studies will contribute to improve the present work. Species’ Checklist Supercohort Metatheria Superorder Marsupialia Order Didelphimorphia Family Didelphidae Gray, 1821 Subfamily Didelphinae Gray, 1821 Didelphis Linnaeus, 1758 Didelphis albiventris Lund, 1840 Lutreolina Thomas, 1910 131 ANNOTATED CHECKLIST OF MAMMAL SPECIES Lutreolina crassicaudata (Desmarest 1804) Monodelphis Burnett, 1830 Monodelphis dimidiata (Wagner, 1847) Thylamys Gray, 1843 Thylamys pusillus (Desmarest, 1804) 1 Supercohort Eutheria Superorder Xenarthra 2 Order Cingulata Illiger, 1811 Family Dasypodidae Gray, 1821 Subfamily Dasypodinae Gray, 1821 Dasypus Linnaeus, 1758 Dasypus hybridus (Desmarest, 1804) 3 Subfamily Euphractinae Pocock, 1924 Chaetophractus Fitzinger, 1871 Chaetophractus vellerosus (Gray, 1865) Chaetophractus villosus (Desmarest, 1804) Zaedyus Ameghino, 1889 Zaedyus pichiy (Desmarest, 1804) Subfamily Tolypeutinae Gray, 1865 Tolypeutes Illiger, 1811 Tolypeutes matacus (Desmarest, 1804) Subfamily Priodontinae Gray, 1873 Cabassous Mc Murtrie, 1831 Cabassous chacoensis Wetzel, 1980 Priodontes F. Cuvier, 1825 Priodontes maximus (Kerr, 1792) 4 1 Birney et al. (1996) suggested that the taxon Thylamys pusillus could include two species. A more exhaustive revision of the taxonomic status of T. pusillus is nedeed. 2 Reig (1981) include the cohort Paratheria (=Edentata) as a taxon between the supercohort Eutheria and the superorder Xenarthra, with the intention to include the pangolins as a sister group of the Xenarthra, in the superorder Nomarthra, Order Pholidota. For practical reasons, and to simplify the present scheme, we omitted the inclusion of Paratheria in the checklist. 3 Roig (1991) includes the northest part of Córdoba Province in the distribution of E. sexcintus; we could not find any reference indicating that this species is found in the province. 4 Called P. giganteus Fischer, 1814 by Cabrera (1958). Only one individual was recorded in the last ten years (Aprile and Massoia, 1989). Subfamily Chlamyphorinae Bonaparte, 1850 Chlamyphorus Harlam, 1825 Chlamyphorus truncatus Harlam, 1825 Order Chiroptera Suborder Microchiroptera Family Phyllostomidae Gray, 1825 Subfamily Desmodontinae Bonaparte, 1845 Desmodus Wied-Neuwied, 1826 Desmodus rotundus (E. Geoffroy, 1810) Family Vespertilionidae Gray, 1821 Subfamily Vespertilioninae Gray, 1821 Eptesicus Rafinesque, 1820 Eptesicus furinalis (d’Orbigny, 1847) Histiotus Gervais, 1856 Histiotus macrotus (Poeppig, 1835) Histiotus montanus (Philippi and Landbeck, 1861) Lasiurus Gray, 1831 Lasiurus blossevillii (Lesson and Garnot, 1826) 5 Lasiurus cinereus (Beauvois, 1796) Lasiurus ega (Gervais, 1856) Myotis Kaup, 1829 Myotis levis (I.

Geoffroy, 1824) 5 Following Baker et al. (1988), and Morales and Birckham (1995), we consider the South American red bat, previously known as L. borealis, as L. blossevillii. 6 Called M. major by Cabrera (1958:130). 132 M. Morando and J.J. Polop Order Carnivora Suborder Caniformia Family Canidae Fischer, 1817 Lycalopex Burmeister, 1954 Lycalopex culpaeus (Molina, 1782) 7 Lycalopex gymnocercus (Fischer, 1814) 8 Family Mustelidae Fischer, 1817 Subfamily Lutrinae Bonaparte, 1838 Lontra Gray, 1843 Lontra longicaudis (Olfers, 1818) 9 Subfamily Mephitinae Bonaparte, 1845 Conepatus Gray, 1837 Conepatus chinga (Molina, 1782) Conepatus humboldtii Gray, 1837 Subfamily Galictinae Reig, 1957 Galictis Bell, 1826 Galictis cuja (Molina 1782) Lyncodon Gervais, 1845 Lyncodon patagonicus (de Blainville, 1842) Suborder Feliformia Family Felidae Fischer, 1817 Subfamily Felinae Fischer, 1817 Herpailurus Severtzov, 1858 Herpailurus yaguarondi (La cépède, 1809) Lynchailurus Severtzov, 1858 Lynchailurus pajeros (Desmarest, 1816) Oncifelis Severtzov, 1858 Oncifelis geoffroyi (d’Orbigny and Gervais, 1844)10 Puma Jardine, 1834 Puma concolor (Linnaeus, 1771) Order Artiodactyla Family Camelidae Gray, 1821 Lama G. Cuvier, 1800 7 The subspecies Lycalopex culpaeus smithersi (Thomas) is restricted to Pampa de Achala, Córdoba (Cabrera, 1958:232). 8 Lycalopex gymnocercus and L. griseus are considered as clinal variations of the same species (Zunino et al.,1995). 9 Called platensis by Olrog and Lucero (1981) and Cabrera (1958). 10 The type locality of the subspecies Oncifelis geoffroyi salinarum Thomas, is Cruz del Eje, Córdoba. Lama guanicoe (Müller, 1776) 11 Family Cervidae Goldfuss, 1820 Subfamily Odocoileinae Pocock, 1923 Mazama Rafinesque, 1817 Mazama gouazoupira (G. Fischer, 1814) 12 Family Tayassuidae Palmer, 1897 Pecari Reichenbach, 1835 Pecari tajacu (Linnaeus, 1758) 13 Order Rodentia Suborder Sciurognathi Family Muridae Illiger, 1815 Subfamily Sigmodontinae Wagner, 1843 Tribu Akodontini Akodon Meyen, 1833 Akodon azarae (Fischer, 1829) Akodon boliviensis Meyen, 1833 Akodon dolores Thomas, 1916 Necromys Thomas, 1916 Necromys benefactus (Waterhouse, 1837) 14 Oxymycterus Waterhouse, 1837 15 11 The distribution of this species is restricted to a provincial reserve (Ronchetti, 1994). 12 Although the specific name is based on the gouazobira of Azara, the original spelling was “gouazoupira” not gouazoubira (Grubb, 1993). 13 As cited by Grubb (1993), the use of appropiate generic names for these taxa is controversial. The correct generic name for collared peccaries appears to be Pecari. 14 This genre, before being recognized in this taxonomic category, was used as a subgenre of Akodon by Ellerman (1941) and Cabrera (1961), and was also used as a synonym of Cabreramys. Reig (1987) determined its statuts and incorporated Cabreramys as a synonym of Bolomys. Nevertheless, Massoia and Pardiñas (1993), using the original rest in a new study, consider the Necromys genre (Ameghino, 1889) valid, placing Bolomys as a subjective synonym of Necromys. 15 The taxonomy of this genus is still unknown. Vitullo et al. (1986), has shown that the karyotypes of several species are identical. In his latest work, Hershkovitz (1994) divides the genus into an Atlantic Division and an Andean Division. However, he gives no instructions about how to identify the different taxa. Polop (1989, 1991) determined the presence of O. paramensis based on morphologic and fur characteristics. Galliari (per. com.) suggested that this characteristics could be phenotipic variations of O. rufus related with the altitude, so that we do not include it in the present work. 133 ANNOTATED CHECKLIST OF MAMMAL SPECIES Oxymycterus rufus (Fischer, 1814) Tribu Oryzomyini Vorontzov, 1959 Holochilus Brandt, 1835 Holochilus sp.

Gervais and Ameghino, 1880 Microcavia australis (I. Geoffroy and d’Orbigny, 1833) Subfamily Dolichotinae Pocock, 1922 Dolichotis Desmarest, 1820 Dolichotis patagonum (Zimmerman, 1780) Dolichotis salinicola Burmeister, 1786 Suborder Hystricognathi Family Chinchillidae Bennett, 1833 Lagostomus Brooks, 1828 Lagostomus maximus (Desmarest, 1817) Family Hydrochaeridae Gray, 1825 Hydrochoerus Brisson, 1762 Hydrochoerus hydrochaeris (Linnaeus, 1766) Family Myocastoridae Ameghino, 1904 Myocastor Kerr, 1792 Myocastor coypus (Molina, 1782) Family Ctenomyidae Lesson, 1842 Ctenomys Blainville, 1826 19 Ctenomys osvaldoreigi Contreras, 1995 Ctenomys rosendopascuali Contreras, 1995 Ctenomys pundti Nehring, 1900 Ctenomys bergi Thomas, 1902 Introduced mammals 16 Cosquín village, Córdoba, is the type locality of the form Calomys venustus (Thomas, 1894), recognized by Cabrera (1961), but synonymized Calomys callosus by Hershkovitz (1962). Musser and Carleton (1993) followed this criterion and considered C. venustus as synonym of C. callosus. In spite of that, citogenetic studies using individuals of the type locality of C. callosus in Paraguay and from the central region of Argentina (Hurtado and Wainberg, 1974; Lisanti et al., 1976; Pearson and Patton, 1976; Gardenal et al, 1977; Forcone et al., 1980; Reig, 1984; Vitullo et al., 1990) allow the revalidation of Calomys venustus. 17 Theiler and Blanco (1996 ) found that the karyomorph 2n = 42 from Córdoba is a separate sibling species from those of the 2n = 38-36 complex (G. griseoflavus). 18 The complexity of this species needs further information. In previous works in Córdoba Province, the authors called it P. darwini, but there is a controversy in whether this species would be assigned to P. darwini or to P. xanthopygus. Here we followed Galliari et al. (1996). Order Lagomorpha Family Leporidae Fischer, 1817 Lepus Linnaeus, 1758 Lepus europaeus Pallas, 1778 Order Rodentia Suborder Sciurognathi Family Muridae Illiger, 1815 Subfamily Murinae Illiger, 1815 Mus Linnaeus, 1758 Mus domesticus Schwarz y Schwarz, 1953 19 The assemblage of Ctenomys species has more than 60 representatives in South America. This genus is being reviewed by Contreras (1995a, 1995b) and Contreras et al. (1994). The species are variable in chromosome number, but fairly uniform in morphology. In the Córdoba plain in the south of Río Cuarto, there are dispersed populations that belong to the “mendocinus complex”. The status of each one is not clear, and they probably are new species. 134 M. Morando and J.J.
