Taxonomic status of nominal species of the anchovy genus Stolephorus previously regarded as synonyms of Stolephorus commersonnii Lacepède 1803 and Stolephorus indicus (van Hasselt 1823), and descriptions of three new species (Clupeiformes: Engraulidae)

H. Motomura

Encrasicholina auster sp. nov. (Clupeiformes: Engraulidae) is described on the basis of six specimens collected from Fiji, southwestern Pacific Ocean. The new species is distinguished from congeners by the following combination of characters: long upper jaw (posterior tip extending beyond posterior margin of preopercle) 20.8%–22.5% standard length (SL); long lower jaw 19.0%–20.7% SL; long head 29.1%–29.2% SL; three unbranched rays in the dorsal and anal fins; transverse scales 11; branched pectoral‐fin rays 12–13; pseudobranchial filaments 19–21; gill rakers 45–49, 40–43, 26–31 and 22–25 on the first, second, third and fourth gill arches, respectively.

Stolephorus continentalis, a new anchovy from the northwestern South China Sea, and redescription of Stolephorus chinensis (Günther 1880) (Clupeiformes: Engraulidae)

Examination of numerous specimens characterised by predorsal scute, long maxilla, indented preopercle and pelvic scute lacking a spine and previously identified as Stolephorus bengalensis (Dutt & Babu Rao, 1959) or Stolephorus insularis Hardenberg, 1933, revealed four distinct species, true S. bengalensis (distributed from the Bay of Bengal to Pakistan) and three new species, viz., Stolephorus eldoradosp. nov. (Taiwan to Java, Indonesia), Stolephorus diabolussp. nov. (Strait of Malacca, from Penang , Malaysia, to Singapore) and Stolephorus eclipsissp. nov. (Bintan Island, Riau Archipelago, Indonesia). Characters separating the four species include numbers of gill rakers on each gill arch and vertebrae and pelvic fin and dorsal-fin ray lengths. Two molecular markers (mitochondrial cytochrome b and cytochrome oxidase I genes) demonstrated the distinction of three of the species examined morphologically and enabled a reconstruction of their phylogenetic relationships. Each species was genetically divergent from the others by 3.5%–7.7% mean uncorrected distance in the mitochondrial cytochrome oxidase I gene.
