Аннотация

In the family Scincidae, karyotypes of most species have diploid numbers of 28–32 chromosomes. They are bimodal, i.e. there are two distinct size classes of chromosomes: microchromosomes and macrochromosomes. Previous karyotypic studies of the common supple skink, Lygosoma bowringii, showed the karyotype comprising 18 macro-and 14 microchromosomes (2n=32), which is common for the family. Here, we described a new derived unimodal karyotype of L. bowringii with 2n=24, observed in individuals from Bangkok (Thailand). A difference between the newly and previously described karyotypes of this species suggests the possibility of cryptic intraspecific chromosomal diversity.
