Resurrection of nominal species previously regarded as junior synonyms of Thrissina baelama ( Fabricius, 1775) and their re-descriptions (Teleostei: Clupeiformes: Engraulidae)

Examination of available type specimens, original descriptions, as well as many non-type specimens collected over extensive geographic ranges, of seven nominal species previously regarded as junior synonyms of Thrissina baelama (Fabricius, 1775) confirmed the validities of five taxa. These are Thrissina evermanni (Jordan & Seale, 1906), Thrissina polynemoides (Gunther, 1868), Thrissina samam (Montrouzier, 1857), and Thrissina tuberculosa (Lacepede, 1803). These four resurrected taxa are re-diagnosed with detailed colour descriptions. Additionally, Engraulis nesogallicus Bennett, 1832 and Engraulis macrops Kishinouye, 1911 are regarded herein as a junior synonym of T. tuberculosa and T. samam, respectively. Neotypes are designated for T. baelama, E. nesogallicus, T. samam, and T. tuberculosa, with clarification of their taxonomic histories.
