Abstract
A new species of Asqllamiceps with a striking cobalt blue head is described from specimens collected at bathypelagic (ca. 2,000 m) depths in the Atlantic Ocean. The new species is compared to the five nominal species in the genus and a key to Asqllamiceps is presented. One nominal species. A. indagatio, is treated as a junior synonym of A. velaris. The anatomy of A. caerlilells suggests a relatively primitive grade within the family. The caudal skeleton, with two to four ural centra, four uroneurals, and the distal edge of the lower hypurals ahead of the distal edge of the upper hypura]s, is one of the most primitive known in the family. Most derived characters found, such as no mesocoracoid, two epurals and no pelvic splint, are reductional. Suspected relationships of Asqllamicep~' are with Einara, COllocara. Leptoderma, and AlIlostomomorpha.
