Synonyms or described as: No recorded synonyms.

Description: Gobiodon winterbottomi is uniformly dark brown, grey to black in colour ( Figure 27). Fins are typically lighter in colour than the rest of the body. There are no markings on the head or body region of this species. The first dorsal fin, unlike congeners, is not rounded, but trapezoidal in shape ( Suzuki, Yano and Senou, 2012). There are no known appearance differences between adults and juveniles aside from size variation ( Suzuki, Yano and Senou, 2012). Adults have been recorded around 30mm SL, whilst juvenile members are smaller at 20mm SL ( Suzuki, Yano and Senou, 2012). The darker pigmentation is shared with G. acicularis , G. ater and G. ceramensis . The trapezoidal shape of the first dorsal find and the fins being a lighter colour than the body colour can be used to identify G. winterbottomi amongst similarly coloured dark grey/black congeners.

Distribution: The current known distribution is restricted to Iriomote-jima Island in the Ryukyu Islands of Japan ( Suzuki, Yano and Senou, 2012).

Habitat: Gobiodon winterbottomi are found primarily within the whorled plate-shaped coral Echinopora lamellose, (Esper, 1971) on the reef slope at depths of 5–8 m ( Suzuki, Yano and Senou, 2012).

Status: The population currently has insufficient data collected to designate an IUCN status ( Larson, 2019j).

Sociality: No known studies of sociality have been conducted for the species.

Genetics: No known genetic analyses have been conducted for the species.
