Cryptocentrus cyanospilotus is distinguished from other shrimp-gobies in Singapore by its distinctive colour pattern - dark brown with small blue spots on the sides of the head and body, grey on the top of the head, two grey saddles on either side of the first dorsal fin, whitish pelvic fins, and narrow whitish bars on the body. It occurs in the tropical western Pacific from the Ryukyu Islands of Japan southwards to New Guinea and the Solomon Islands (Allen & Erdmann, 2012: 871). The species was first recorded from Singapore as ‘Cryptocentrus new species 2’ based on a photograph also taken off Pulau Hantu in 2006 (Larson et al., 2008: 144, fig. 7 & 148).
