Estudios sobre la Herpetofauna Canaria I. El Cariotipo de Gallotia simonyi stehlini y de G. atlantica spp. en Poblaciones de la Isla de Gran Canaria1

Abstract

AbstractA karyological analysis on lizards of the Canary Islands Gallotia simonyi stehlini and G. atlantica ssp., resulted in both cases in a formula of 2n = 40 (38 1 + 2 m; NF = 40); what, besides the results in Gallotia galloti, defines the genus Gallotia (Lacertidae) endemic of the Canary Islands as a monophyetic unit. Considering the ancestral characteristic demonstrated in several species of this genus by diferent authors such as some morphological aspects (the hemipenis) as well as ethological aspects (copulatory ritual), it pointed out the important coincidence of the karyotype of these species and its relictual character. The similarities with Lacerta jayakari of Oman, are commented taking into consideration the botanical connections between the Canary Islands and south-eastern Arabia.
