Description

Eudalaca cipollai sp. n. is described from a forest reserve in a Mistbelt forest of KwaZulu-Natal Province, South Africa. The species is characterized by a dark brown forewing with several prominent white patches. These features are distinct from all other Eudalaca Viette, 1950 species. Inclusion of the species within Eudalaca is justified by the prominent expanded blade-like structure of the distal valva in the male genitalia that is characteristic of many Eudalaca species and absent from other southern African genera where genitalia are described. The monophyletic status of Eudalaca and other southern African genera is briefly reviewed. It is suggested that the male genitalia of the monobasic Leto Hübner, 1820 are most similar to that of Gorgopis Hübner, 1820, while the male genitalia of the monobasic Chilean genus Blanchardinella Nielsen, Robinson & Wagner, 2000 show greater structural similarity with Gorgopis and Eudalaca than other South American genera.
