|Abstract||A closer study and becoming available of additional material show the desirability of describing a new genus and species of Tortricidae from Southern Asia.|
The author is indebted to Prof. Dr. W. Sauter and Mrs. M. Horak, Eidgenössische Technische Hochschule, Zürich, Switzerland, for kindly putting at his disposal material of one of the species, recently collected in New Guinea and for the premission to retain duplicates for the Leiden Museum collection.
The figures are by Mr. A. C. M. van Dijk, The Hague and by the author.
