Questions on systematics and taxonomy
in parthenogenetic species have been
discussed by several authors (DAREVSKY
1967; MASLIN 1968; BÖHME 1975,
1982; COLE 1985; WALKER 1986;
FROST & WRIGHT 1988). As far as unisexual
lizards are concerned in particular,
we think that the most acceptable hypothesis
is that of COLE (1985). According to
his opinion morphologically different parthenoforms
of hybrid origin which are
self-supporting, genetically unique, and
independently evolving entities should be
regarded as separate species. Parthenoforms
which have different ploidy and result
from hybridization of different parental
forms should be regarded as separate
species, irrespective of the degree of their
morphological differences. Whenever parthenoforms
have the same origin and ploidy
but differ in other features, they should
be regarded as separate clones within one
unisexual species. According to COLE's
(1985) point of view the semi fertile but
self-supporting triploid lizards L. triploida
and L. guentherpetersi have to be considered
as indepedent unisexual species.
