that L. triploida could have originated
from hybridization of parthenogenetic diploid
females and males of the widely distributed
Thailand species L. belliana.
Hypothesizing on potential parental
couples which could have participated in
the formation of the parthenogenetic
species, the present day distribution of all
bisexual and parthenogenetic forms that
might hybridize is of great importance.
According to the dato of PETERS (1971)
the geographic distribution of L. triploida
is not clear, but terra typica of this species,
which apparently inhabits northern Malaysia,
is the region of the Malaysian-Thailand
boundary. This suggests that L.
triploida occurs also in the south of Thailand,
from where the diploid L. boehmei
sp. nov. is known. The characteristics of
coloration (fig. 8) and some morphological
characters, which are intermediate between
L. boehmei and L. belliana in L. triploida,
also speak in favour of BÖHME's hypothesis.
In particular, L. triploida adopted the
bright lateral and dorsomedian stripe as
well as the characteristic reticular pattern
from the unisexual maternal species.
The origin of the probably diploid
parthenogenetic species L. boehmei remains
an unsolved problem so far. There is
