Notes.
When this taxon was described as a subspecies of
Lethe elwesi
,
Lang & Bozano (2015)
compared it with material of
L. giancbi
Lang & Das
sp. nov.
from SE
Tibet
which was identified as the nominate
L. elwesi
in that work. After checking all male genitalia of species in the
jalaurida
-subgroup, the present authors think that this taxon is quite different from
Lethe elwesi
and should be a distinct species which is more closely related to
L. giancbi
Lang & Das
sp. nov.
than to the others.
Diagnosis.
1) On both sides pale markings and stripes are yellowish, it is similar to
Lethe atkinsonia
but without male brand on dorsal forewing; 2) uncus is heavily bent downwards; 3) valva is not elongated as in
L. giancbi
sp. nov.
; 4) valva apex is sharply pointed inwards; 5) aedeagus has a slender dorsal ridge near its cephalic end, this structure is also present in
L. giancbi
sp. nov.
but absent in other species.
