A new species of Soleichthys (Soleidae: Pleuronectiformes) from tropical seas off northern Australia

Abstract

Soleichthys maculosus, described from six specimens collected in shallow waters (37–63 m) off northern Australia, is readily distinguished from congeners by its unique ocular-side pigmentation featuring numerous, conspicuous white spots and blotches nearly as large as the eye diameter on a uniformly dark brown background without any crossbands, and in having two elongated, ocular-side pectoral-fin rays, with the second dorsalmost ray longer than the first, and without scales on the pectoral-fin rays. Soleichthys maculosus is most similar to S. siammakuti, a poorly-known species collected in the Gulf of Thailand, but differs from S. siammakuti in having the second dorsalmost ocular-side pectoral-fin ray longer than the first (vs. first ocular-side pectoral-fin ray longer in S. siammakuti), and in having different ocular-side pigmentation than that of S. siammakuti, which features yellow spots on dorsal and anal fins, two conspicuous white spots arranged in longitudinal series on the lateral line, and also a series of nine, light brown crossbands on a dark brown body.
