Sicyopterus calliochromus is a species of goby in the family Oxudercidae, or alternatively, Gobiidae. It is only known from the waters of the Tirawiwa River, which is a major tributary of the Wapoga River, which in turn flows into the eastern edge of Cenderawasih Bay, in the Papua Province in Indonesia.[1]
Sicyopterus calliochromus can reach a standard length of 5.8cm (02.3inches).
