dc.description.abstract"Two species of anchovies of the genus Stolephorus, S. multibranchus and S. nelsoni, are described from Ponape, Caroline Islands and Wallal, Western Australia, respectively. They possess a rounded posterior edge of the preoperculum, a long maxilla which reaches posteriorly beyond the anterior margin of the preoperculum, 12-3 branchiostegal rays, 20-23 anal-fin rays, 13-15 pectoral-fin rays; they lack a predorsal spine and an interpelvic scute. S. multibranchus is similar to S. pacificus in having a high gill-raker count (25-27 + 32-35 and 21-27 + 33-38, respectively), but that species has a much shorter maxilla. Compared to all other congeneric species which have comparatively fewer gill rakers (13-24 + 18-31), S. multibranchus is closest to S. commersonii in having a similar pair of dusky bands on the midline of the back from occiput to origin of dorsal fin. S. nelsoni resembles S. apiensis and S. commersonii, but differs from them in having toothed knobs at the bases of the anterior gill rakers on epibranchial one, greater body depth (22.9-23.3 vs. 17.0-22.6% SL), longer head (26.7-27.3 vs. 19.8-26.4% SL), fewer predorsal scales (15 vs. 17-19), and series of dark dots at the bases of the dorsal and anal fins usually absent. Included are figures of the new species, and a key to 18 species of Stolephorus together with an Indo-Pacific species of Engraulis and five species of Encrasicholina"--P. [1].en_US
