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 View FIGURES 17 – 22 , 26 View FIGURES 23 – 28 , 32 View FIGURES 29 – 34 ): e) The uncus of this species is longer than that of L. jalaurida ( Figs. 21, 22 View FIGURES 17 – 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 .
