Taxonomic Studies on Three Caeneressa Species (Lepidoptera: Syntominae) from India with Special Reference to Their External Genitalia

摘要

Caeneressa diaphana muirheadi (Felder) and Caeneressa brithyris (Druce) have been recorded for the first time from India. Further, a new combination viz. Caeneressa melaena (Walker) comb, nov., has also been proposed on the basis of external genitalicfeatures. With these records, genus Caeneressa will be represented by five species from India, Caeneressa diaphana (Kollar), Caeneressa diaphana muirheadi (Felder), Caeneressa brithyris (Druce), Caeneressa melaena (Hampson) and Caeneressa swinhoei (Leech). The studied material was collected from North-Eastern states of India. Caeneressa brithyris (Druce) was collected near riverside at low altitude whereas the other two species were collected at high altitude.
