Genus Redigobius

The genus Redigobius occurs throughout the Indo-west Pacific, in estuarine to fresh water habitats, with R. bikolanus being the most widespread species.
Redigobius can be distinguished by the following combination of characters: dorsal-fin rays I,6-8; anal-fin rays I,6-7; modally with one more ray in second dorsal fin than in anal fin; 17 segmented caudal rays; sensory canals on head with complete oculoscapular and preopercular canals and pores; sensory papillae arranged in longitudinal pattern, jaws terminal, males usually with enlarged mouths; 11-12 precaudal and 14-16 caudal vertebrae and usually three or four anal-fin pterygiophores before first caudal haemal spine (Larson 2010).
