Biological Society of Washington the Karyotype of Vanzolinius Discodactylus and Comments on Usefulness of Karyotypes in Determining Relationships in the Leptodactylus-complex (amphibia, Leptodactylidae) by W. Ronald Heyer and M. Judith Diment

چکیده
Information on karyotypes of several species of Üié frog genera Adenomera and Leptodactylus recently has become available. Bogart (In press) described and figured the karyotypes of 16 species of Leptodactylus and 3 species of Adenomera (reported as the marmoratus group members of the genus Leptodactylus). We have obtained information on the karyotypes of 9 species of Leptodactylus and Vanzolinius discodactylus. The purpose of this paper is to describe the karyotype for the previously unreported V. discodactylus and offer alternatives to the relationships among the Leptodactyluscomplex to those proposed by Bogart (In press). It should be pointed out that the genera Adenomera, Leptodactylus, and Vanzolinius have been considered to all belong to the genus Leptodactylus until recently.

The relationships of Leptodactylus discodactylus Boulenger have been obscure. In the first analysis of the relationships of discodactylus since Boulenger's description, I (1970) placed this species in the Melanonotus group of the genus Leptodactylus, based primarily on external morphology. This relationship was questioned when certain life history data were gathered (Heyer and Belhn, 1973). In ...

The Identification of Rana Ocellata Linnaeus, 1758. Nomenclatural Impact on the Species Currently Known as Leptodactylus ocellatus (Leptodactylidae) and Osteopilus brunneus (Gosse, 1851) (Hylidae)
The usage of the name Rana ocellata Linnaeus, 1758, is plagued by misidentifications and misinterpretations. After an exhaustive bibliographic review, we conclude that the Linnaeus 1758 name refers to Osteopilus brunneus (Gosse, 1851) from Jamaica, while the taxon currently known as Leptodactylus ocellatus corresponds to Rana latrans Steffen, 1815. Herein, we designate and provide descriptions ...

The frog Leptodactylus fuscus is found throughout much of South America in open and disturbed habitats. Previous study of genetic differentiation in L. fuscus demonstrated that there was lack of genetic exchange among population units consistent with multiple species, rather than a single species. We examine advertisement vocalizations of L. fuscus to determine whether call variation coincides ...
