Un nouveau chiroptère vespertilionide de l'Oligocène d'Europe
Bernard Sigé and Henri Menu
Keywords: bats; Europe; nov. sp.; Oligocene; Vespertilionid
 
  Abstract

    A fossil species of the extant genus Leuconoe, L. lavocati n. sp. from Le Garouillas Oligocene locality, Quercy phosphorites, SW-France, is established in nomenclatural standards.

Sur le statut taxonomique de Myotis KAUP 1829 (Mammalia, Chiroptera).
Henri Menu
Keywords: Myotis; Taxonomy
 
  Abstract

    Suite à la récente publication d'une révision systématique des Chiroptera Vespertilioninae, conduite sur la base des morphologies dentaires comparées (Menu 1987), une remarque bienveillante du Dr. V. Aellen (Muséum d'Histoire Naturelle de Genève) a attiré l'attention de l'auteur sur un point précis du Code International de Nomenclature Zoologique.

Morphotypes dentaires actuels et fossiles des chiroptères vespertilionines. 2ème partie: implications systématique et phylogéniques.
Henri Menu
Keywords: Chiroptera; Phylogeny; systematics; Vespertilionine
 
  Abstract

    The first part of this study was devoted to a descriptive analysis of teeth morphologies among the vespertilionine bats. This leads now to a tentative synthesis, providing views on the systematics of the group. The results could be seen according to three distinct but closely related purposes : 1 - the sorting of the genera contents in order to conform the genera units to homogeneous taxa that could represent natural issues of evolutionary lineages ; 2 - the investigation of relationships between extant genera in order to infer the possibilities of common origin ; 3 - according to the preceeding items and to the observed evolutionary trends, a tentative phylogeny, modest and cautious. The contents of many genera are sorted : Leuconoe is removed from subgeneric to generic position, whereas Myotis becomes a subgenus of it ; the myotodont species are cleared away from the Pipistrellus genus ; Glischropus and Scotozous are synonymized within Pipistrellus ; Hypsugo is raised to the generic level ; some species previously ranged within Pipistrellus will form provisionally a collective group, Attalepharca nov. ; the Eptesicus genus is broken up, the excluded species being grouped within Nycterikaupius gen. nov. ; the Nycticeini tribe is defined again after exclusion of Otonycteris , Scotoecus, Scotophilus , and addition of Hesperoptenus ; the species la io and Pipistrellus tasmaniensis are removed to Eptesicus (n.s.) and Pipistrellus dormeri to Scotoecus. Groupings of genera are stated according to the main evolutionary trends of I1/. The relevance of these is often warranted by close morphologic similarities of other teeth. This leads to a recognition of the major evolutionary radiations which occurred in the group. The filiations schematized at the end of the work show the dental relationships observed between the extant genera, and could represent a phylogenic framework. Two major facts are to be underlined : 1- the early divergence of leuconoids ; 2 - the successives crossings to myotodonty from the nyctaloid flow. Fossil data from the literature are punctually and tentatively incorporated within phylogenic sketches.

Morphotypes dentaires actuels et fossiles des Chiroptères Vespertilioninés. 1e partie: Etude des morphologies dentaires
Henri Menu
Keywords: bats; dental morphology; fossils; Phylogeny; recent; systematics
 
  Abstract

    The classifications of the recent vespertilionine bats were made wihtout taking in account the teeth morphology; this resulted in a reduction of the possibilities of comparison with the available fossils. The generalized use of dental formulae was abusive: this contributed to the admission of artificial genera. These conditions have long delayed the consideration of characters able to frame the phylogeny of the sub-family. In the first part of the study, the teeth morphologies are described and analysed. morphological reference types are established for each upper and lower tooth: they should make an easier elaboration of criteria for the differentiation at generic level. The position of the species in view of these criteria allows one to group them into homogeneous genera, and to appreciate the degree of relationship that the latter have between them. The second part of the study (next publicationà will develop inferences dealing with systematics and phylogeny
