A revision of the moth genus Ceratonyx (Lepidoptera, Geometridae). American Museum novitates ; no. 2564

Abstract

"The genus Ceratonyx is revised for the first time. Twelve species are included and five described as new: crassa (Mexico), fessa (Chile), crebra (Chile), aculeata (Chile), and tora (Mexico). In addition, constantia Dyar is placed in the genus for the first time. The species of the genus are found in the southern portion of the United States to the mountains of central Mexico, and in the Andes of central Chile. Ceratonyx is divided into two species groups based primarily on the characters of the male genitalia. All species are described; keys and photographs are presented for the adults, and for both male and female genitalia. The tribal placement of Ceratonyx is discussed, as are possible evolutionary changes within the genus"--P. [1].
