Abstract
Laemonema yuvto sp.nov. is described from a single specimen 191mm SL from the Sala y Gomez Ridge. Although this species is similar to L. robustum and L. filodorsale in most proportions of head and body, it differs from both in having shorter second ray in first dorsal fin and more rays in second dorsal and anal fins. It also differs from L. robustum in maxillary not reaching the vertical from posterior margin of orbit and shorter pelvic fin, and from L. filodorsale in longer pelvics, fewer oblique rows of scales above lateral line and the absence of enlarged teeth in both jaws.
