Review of Pennella Oken, 1816 (Copepoda: Pennellidae) with a description of Pennella benzi sp. nov., a parasite of Escolar, Lepidocybium flavobrunneum (Pisces) in the northwest Atlantic Ocean Author Hogans, W. E. text Zootaxa 2017 4244 1 1 38 journal article 36256 10.11646/zootaxa.4244.1.1 05f1a37b-29f3-4bca-a735-178a3373bb8a 1175-5326 400400 781D71C8-4632-4D1B-8D82-F77CA1146029 Pennella zeylanica Kirtisinghe, 1933 Not valid. Reported from Pacific sailfish, Istiophorous gladius (= I. platypterus ), Ceylon. The original description and figures clearly indicate that P. zeylanica is identical with P. instructa of Wilson (1917) (cephalothoracic papillae and holdfast horn configuration is the same between the two species) which is also found on sailfish ( Hogans 1986 and references therein ). Synonym of P. instructa ( Hogans 1986 ) ; accepted as P. instructa ( Walter & Boxshall 2015 ) .
