Diagnosis.
Lethe elwesi
can be distinguished from
L. jalaurida
by the combination of the following characters: a) Usually larger in size (forewing length:
24–27 mm
in
elwesi
;
24–25 mm
in
jalaurida
); b) Ventral forewing, dark postdiscal band, bordered distally by yellow, has an irregular shape, whereas it forms three sharp regular angles in spaces 1, 2 and
3 in
L. jalaurida
; c) Ventral hindwing, silver discal band is continuous, whereas it is broken in cells 3 and
4 in
L. jalaurida
; d) Ventral hindwing, basal half silver markings are more developed than those of
L. jalaurida
; Male genitalia (
Figs. 20
,
26
,
32
): e) The uncus of this species is longer than that of
L. jalaurida
(
Figs. 21, 22
); f) The gnathos is longer than that of
L. jalaurida
; f) The aedeagus has a slender dorsal ridge near its cephalic end, whereas the dorsal surface of aedeagus is smooth in
L. jalaurida
.
