- On the geographical differentiation of Gymnodactylus geckoides Spix, 1825 (Sauria, Gekkonidae): speciation in the Brasilian caatingas Paulo Emilio Vanzolini Multidisciplinaria (Ciencias Naturales y Exactas) speciation Holocene refuges lizards: ecology lizards: systematics The specific concept of G. geckoides was initially ascertained based on a topotypical sample from Salvador,Bahia. Geographic differentiation was studied through the analysis of two meristic characters (tubercles in aparamedian row and fourth toe lamellae) and color pattern of 327 specimens from 23 localities. It is shownthat the population from the southernmost locality, Mucugê, is markedly divergent in all characters studied.A Holocene refuge model is proposed to explain the pattern. A decision about the rank to be attributed to theMucugê population is deferred until more detailed sampling is effected and molecular methods are applied. 2004 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32776405 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.76
