Body short and deep (Ref. 4966). Body depth 1.8-1.9 in SL (Ref. 90102). This species differs from both C. fieldi and C. dimidiata by having 13 or 14 dorsal soft rays compared to modally 12 dorsal rays, the demarcation of dark brown anterior and white posterior colors anterior to the origin of the anal fin (the pectoral-fin tips passing distinctly posterior to the demarcation), and the genetic differentiation is distinct at mtDNA (Ref. 92902).
