A new squid species of the family Lycoteuthidae, Nematolampas venezuelensis is recognized from the central western Atlantic Ocean. The new taxon is characterized by the threadlike, greatly elongated ventro-lateral arms and the presence of a single, large photophore embedded in
the musculature of the fin/mantle complex. An overview of the Family Lycoteuthidae is presented based on the examination of the holotypes of Nematolampas regalis and Oregoniateuthis springeri, reported specimens of Selenoteuthis scintillans and Lampadioteuthis megaleia,
and a review of the literature on the family.
