Abstract
The monotypic genus Chandata MOORE, 1882, with its type-species Chandata partita MOORE, 1882, is one of the genera whose taxonomic status remains uncertain among a peripheral assemblage of Euplexia STEPHENS and/or Trachea OCHSENHEIMER. The arrangement made by HAMPSON (1908) and WARREN (1913) has never been revised or discussed on the basis of genitalic morphology. Through the kindness of Mr. M. OWADA of the National Science Museum (Nat. Hist.), Tokyo, I was given an opportunity to examine two males of Chandata partita MOORE and a fairly long series of its close relative from Nepal obtained by him during the zoological expedition to Nepal Himalaya 1979 made by the museum. After a careful study, I have reached the conclusion that the genus Chandata MOORE should be given a revalidated status and that the two known species now placed under Euplexia, E. bella (BUTLER, 1881) and E. aglaja KISHIDA et YOSHIMOTO, 1978, should be placed in this genus. On the other hand, I became aware of the fact that the Taiwanese specimens erroneously identified with Euplexia bella (BUTLER) by KISHIDA and YOSHIMOTO (1978) belonged to a new species. Further, I was able to examine Nepalese specimens similar to E. bella collected by the Lepidopterological Society of Japan Expedition to Nepal-Himalaya 1963 through the courtesy of Mr. S. SUGI, Tokyo. They also represent a different new species. In the present paper, I am going to give a re-definition of the genus Chandata MOORE, to describe the three new species and to redescribe E. aglaja based on additional material.
