Gerald R. Allen and Mark V. Erdman: Hoplolatilus andamanensis, a new species of sand tilefish (Pisces: Malacanthidae) from the Andaman Islands and confirmation of H. luteus as a junior synonym of H. fourmanoiri, pp. 1-12

Abstract
Hoplolatilus andamanensis is described on the basis of four specimens, 99.2-110.4 mm SL, collected at the Andaman Islands in the eastern Indian Ocean. The species was previously misidentified as H. luteus, a species that was originally described from a single specimen from Flores, Indonesia. Previous authors have debated the issue of whether H. luteus is a valid species or a junior synonym of H. fourmanoiri. Additional evidence in the form of underwater observations and collected specimens support the contention of Dooley & Jimenez that the two species are synonymous. The new species is closely related to H. fourmanoiri, but differs in scale morphology and coloration. It also usually has 11 dorsal spines versus a usual count of 10 spines in H. fourmanoiri. There is also a 1.5% divergence between the two species based on 16s ribosomal RNA sequence data.
