Rhesala falcata sp. n. 
, 13-14mm. See the previous species for shared differences from imparata. This species is larger and browner than fusiformis, with slightly more irregular postmedials, that of the forewing being more weakly expressed centrally. The labial palps are longer, relatively slightly narrower. The male genitalia have the swollen section of the uncus relatively more basal such that the slender apical part is longer. The saccular part of the valve is more produced on the ventral side and protrudes as a longer spine on the ventral margin. There is no corema. The distal part of the valve tapers much more and is upwardly falcate. The female has a longer and narrower corpus bursae than in fusiformis, the basal rasp-like sclerite being joined by spines within the neck of the bursa.
