Abstract

Engraulis clarki Hildebrand is a junior synonym of Anchoa starksi (Gilbert & Pierson). Lectotypes are designated for Stolephorus starksi Gilbert & Pierson and S. naso Gilbert & Pierson, the type series of each being of mixed composition. Anchovietta, a new subgenus of which S. naso is the type species, is proposed for the Anchoa naso species-group (including also A. filifera, A. lyolepis, A. nasus, A. nasuta). The naso-nasus complex consists of a southern (Peru-Ecuador) nasus form and a northern (Ecuador-Gulf of California) naso form. The lyolepis-nasuta complex consists of a South American nasuta form, an Antillean-Middle American (Caribbean) lyolepis form and a Gulf of Mexico-United States form resembling nasuta. The filifera complex consists of a South American (Brazil-Colombia) filifera form and an Antillean-Middle American (Caribbean) longipinna form. Possible relatives of Anchovietta include other new-world anchovies with a long pseudobranch: Anchoviella elongata, Anchoa marinii, A. starksi. Other species-groups of Anchoa probably have diverse relationships.
