. A morphological study of adults and immature stages and a cladistic analysis were conducted to clarify the relationships amongst members of the sister nymphalid butterfly genera Dircenna Doubleday and Hyalenna Forbes. Two species formerly included in Dircenna , Ithomia paradoxa Staudinger and Dircenna hugia Schaus, clustered with Ithomia perasippa , the type species of Hyalenna . Therefore, the first two species are transferred from Dircenna to Hyalenna ( comb.n .). Hyalenna and Dircenna as now conceived are both monophyletic and well supported by morphological apomorphies and branch support measures. The taxonomy and classification of Hyalenna are reviewed and seven species and twenty‐four taxa are recognized, including one new species, Hyalenna buckleyi sp.n. , and eleven new subspecies: Hyalenna paradoxa incachaca ssp.n. , H. perasippa valencia ssp.n. , H. perasippa ortygiosa ssp.n. , H. perasippa solitaria ssp.n. , H. buckleyi pomacocha ssp.n. , H. alidella exsulans ssp.n. , H. alidella cinereola ssp.n. , H. alidella vesca ssp.n. , H. sulmona balsamica ssp.n. , H. sulmona hyalina ssp.n. and H. sulmona tersa ssp.n. A key for the identification of all taxa, and illustrations of male and female genitalia for all species and adult specimens of all taxa (where known), are presented. The natural history of each species is summarized and the immature stages of H. paradoxa and H. sulmona are described for the first time.
