“…Taxonomic positions of the following 5 populations assignable to P. levipes from Nayarit, Jalisco, and Michoacá n are unclear: population of Ocota, Nayarit (FN 5 65-68) differs from P. levipes based on morphological (Bradley et al 1996;Carleton et al 1982), karyotypic (Carleton et al 1982;Houseal et al 1987), and cytochrome-b sequence data (Bradley et al 2004;Tiemann-Boege et al 2000); population of Dos Aguas, Michoacá n (FN 5 65-68) differs from the other boylii species group based on data concerning karyotype (Houseal et al 1987), allozymes (Rennert and Kilpatrick 1987), and cytochrome-b sequence (Bradley et al 2004;Tiemann-Boege et al 2000); population of Los Reyes, Michoacá n, is fixed for FN 5 66 (Houseal et al 1987;Schmidly and Schroeter 1974); specimens from Volcán de Colima, Jalisco, have FN 5 68 (Houseal et al 1987); and 2 populations of Michoacá n (Pá tzcuaro and Los Azufres) are fixed for FN 5 56 (Houseal et al 1987). Cytochrome-b sequences from populations in Ocota, Nayarit, and Dos Aguas, Michoacá n, are placed in a separate clade, and these populations could represent a different, undescribed species (Bradley et al 2004;Tiemann-Boege et al 2000).…”
