Etymology: Phoxacromion: Name derived from the Greek 'phoxos' for pointed and 'akromion' meaning point of the shoulderblade, referring to the characteristic modification of cleithrum in the type species; kaneharai: Named for H. Kanehara, who provided valuable information and underwater photographs of the species taken from its type locality.
Eponymy: Hiroyuki Kanehara is a diver, guide and photographer working at the Diving Service Amamiensis, Amami Ōshima Island, Ryukyu Islands, Japan. He provided ecological and habitat information about the goby and underwater photographs for the authors. (Ref. 128868), visit book page.

Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8; Vertebrae: 26. This species is distinguished in having the following characters: an expanded lateral wing of the cleithrum with a distinct, anterolaterally-directed triangular mid-lateral margin; D VI-I,9; A I,8; head depressed, depth 75.7-86.7% of width; lower jaw robust and prominent; mental frenum undeveloped; gill opening narrow, extending dorsally to a horizontal line through base of third, fourth or fifth pectoral-fin ray; tongue relatively narrow, anterior tip rounded or near pointed; sensory papillae rows on cheek representing essentially a longitudinal pattern, with short row b not extending anteriorly to a vertical through middle of eye; row c uniserial and long; row cp transverse, comprising 2-3 papillae; sensory papillae 2-4 (usually 3 or 4) forming a transverse row just behind chin (= row f); sensory canals on head well developed, with pores B', C (unpaired), D (unpaired), E, F, G, H', K', L', M', N and O'; vertebrae 10+16+26; P-V 3/II II I I 0/9 (Ref. 84000).
Found solitary under rubbles on sandy and pebble bottoms in protected bays at depths of 2-3 m (Ref. 84000).
