Coconympha is a genus of moth in the family Gelechiidae. It contains the species Coconympha iriarcha, which is found in south-western India. The wingspan is 10–11 mm. The forewings are olive-green with a metallic-blue patch extending along the basal third of the costa and a silvery-white straight direct median transverse line, followed by a metallic-blue streak, the area beyond this wholly black with a coppery-purple-metallic fascia just before the termen. The hindwings are dark fuscous, with the basal half rather lighter. The larvae feed on the leaves of Cocos nucifera.
