Examination of a specimen from Alto Parnaíba, Maranhão,near the type locality (Engenheiro Dodt, Piauí), indicates that it is a proper species, apparently limited to theupper Parnaíba basin. The form previously identified as G. geckoides amarali is described as a new species,G. carvalhoi, type locality Ipueiras, State of Tocantins, thus diagnosed: color pattern plain or, more often,with moderately contrasted ocelli; dorsal tubercles in 13 16 poorly organized longitudinal rows (mode 14,72%); 31 49 tubercles in a paramedian row; 17 22 transverse rows of ventral scales; 13 18 infradigitallamellae on toe IV; tail longest in the genus. The new species is statistically compared to parapatric G.geckoides, widespread in the caatingas. Although only one meristic character (number of tubercle rows) isby itself diagnostic, the species are easily told apart. It is thought on provisional evidence that they are betterconsidered for the time being as full species, not subspecies. A brief consideration is made of the speciationmodel that seems suitable, to wit, parapatric. 2005 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32777403 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.77 |
