There are 12-17 scales in predorsal midline and 33-39 in longitudinal series. The males have more and larger symphyseal teeth than females (3 vs. 2-3). The species has also (13-16) scales in transverse forward series and longer fins in males. The species is squatter than other Stiphodon species and the coloration of males is characteristic: they have yellow green (Ref. 83881).
