Karyotypic diversification due to Robertsonian rearrangements in Phyllodactylus lanei Smith, 1935 (Squamata, Gekkonidae) from Mexico

We analyzed chromosomes of male and female individuals of Phyllodactylus lanei Smith, 1935 (Squamata, Gekkonidae) from Chamela-Cuixmala Biosphere Reserve, Jalisco state, Mexico. The karyotype constructed for these specimens is composed of 19 pairs of telocentric chromosomes (2n = 38, FN = 38). This karyotype, due to Robertsonian fusions/fissions, differs from the one previously reported in samples from the State of Guerrero, which probably belonged to a different subspecies (2n = 33−34, FN = 40−41). Moreover, a presumed ZW sex chromosome system was not confirmed in the presently studied individuals.
