| Remarks | Males possess hypertrophied odontodes and well-developed soft fleshy lobes along the lateral portion of head; unbranched pectoral-fin ray slightly thickened from base to approximately three-fourths of its length, with distal portion soft and with short hypertrophied odontodes on outer and ventral surfaces; and unbranched pelvic-fin ray with developed dermal flap on dorsal surface, extending to ray tip, is distinctly higher close to fin base in comparison to adult females and juveniles. |

| Diagnosis |
Distinguished from all congeners by its unique color pattern consisting of large and conspicuous dark brown blotches irregularly scattered over a yellowish tan background on head, along the dorsal surface of body and flanks, and shallow depression at posterior unpaired plates covering the area otherwise occupied by the adipose fin. Differs from all congeners except Pareiorhaphis nudulus, P. eurycephalus, and P. vestigipinnis by the usual absence of the adipose fin; and from P. nudulus, P. eurycephalus, and P. vestigipinnis by having a shorter pectoral-fin spine 13.9-18.4% SL (vs. 19.3-24.2, 20.0-24.7, and 18.2-21.4% SL, respectively) (Ref. 91754). |
