| Abstract: | 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. |
