Review of Stiphodon (Gobiidae: Sicydiinae) from Western Sumatra, with description of a new species

Abstract

Three Stiphodon species are found on the western slope of Sumatra, Indonesia. They include a new species, S. maculidorsalis, distinguished from its congeners by second dorsal- and pectoral-fin ray counts (usually I, 9 and 15, respectively) and relatively high premaxillary teeth counts, pointed first dorsal fin of male, scalation on dorsum of head and trunk, black spots scattering dorsally on head and trunk of male and female, broad black bands on distal part of second dorsal fin and dorsal part of caudal fin of male, fine black spots on pectoral-fin rays of male, and dusky transverse bars laterally on trunk and tail of female. The other two species are S. ornatus and S. semoni; the latter is first reported from this region, expanding the westernmost limit of the range of this widespread species. These three species appear to form the major components of the Stiphodon gobies in the aquarium trade. © National University of Singapore.
