Remarks
. Differences between
L. nasuta
and
L. bolivariana
(see specimens listed above and below and Figs. 50-53) are very small; according to
Dirsh (1958)
L. nasuta
(type: female; type locality:
KwaZulu-Natal
,
South Africa
) is very near to
L. bolivariana
(type: male; type locality:
Maputo
,
Mozambique
), from which it differs by a more strongly serrated metazona of the pronotum and toothed ventral margin of the hind femur. The photo of the
holotype
female of
L. nasuta
(Fig. 52) was compared with one female of
L. bolivariana
collected in the type locality (
Maputo
; Fig. 53) and it was possible to confirm the different shape of the pronotum above mentioned; in addition the female of
L. nasuta
has small pointed tubercles on the hind margin of the abdominal tergites, not present in
L. bolivariana
(Figs. 52-53). Also in the males [
holotype
of
L. bolivariana
(Fig. 51) compared to a male of
L. nasuta
(Fig. 50) from the type locality, Natal] allowed to confirm the differences of the pronotal shape, while the teeth of the ventral margin of the hind femora are very similar. However, the validity of both species is confirmed here.
The distribution of the two species overlaps (but there are not records of
L. nasuta
from
Zambia
) and they may be found in the same locality; indeed
Dirsh (1958)
reported specimens of
L. bolivariana
from Barberton (
South Africa
), and here specimens of
L. nasuta
are listed from the same locality.
