absence of males in all our samples

absence of males in all our samples confirms
the unisexuality of L. boehmei assumed by
previous authors, because in bisexual
populations of lizards, males are usually
collected more frequently than females, and the
complete absence of males is thus considered to
be a robust evidence of parthenogenetic
reproduction (Darevsky et al., 1988; Peccinini-
Seale, 1972).
All specimens karyotyped possessed a
standard karyotype of 2n = 34, with one
submetacentric and five metacentric pairs of
macrochromosomes and eleven pairs of
apparently acrocentric microchromosomes.
Secondary constrictions were located on the
distal portions of long arms of chromosomes
no.1 (Fig. 3). Its arranged karyotype is shown
in Fig. 4. The haploid number and morphology
of macrochromosomes did not differ from those
of other diploid species, L. belliana, L. guttata
and L. reevesii (Kupriyanova, 1984; Shoubai et
al., 1987; Solleder and Schmid 1988), and of
the triploid L. triploida (Hall, 1970). Even so,
however, the haploid karyotype of L. boehmei
differs from those of other congeneric species
in possessing fewer microchromosomes
