Etymology: Ctenopharynx: Greek, kteis, ktenos = comb + Greek, pharyngx = pharynx (Ref. 45335); intermedius: From the Latin "intermedius" = intermediate, probably referring to the fact that, according to Günther (1864) "this species connects Chromis and Hemichromis" (Ref. 55925).

Max length : 21.0 cm TL macho / no sexado; (Ref. 5595); 16.0 cm TL (female)
Espinas dorsales (total) : 14 - 17; Radios blandos dorsales (total) : 10 - 13; Espinas anales: 3; Radios blandos anales: 9 - 11. Diagnosis: high number of gill-rakers on lower part of outer gill arch (36-39); short head, 32.3-35.8% of standard length; relatively anterior implantation of dorsal, pectoral and pelvic fins; short premaxillary pedicel, 30.4-33.6% head length (Ref. 55925).
Found in sediment-rich areas (Ref. 5595) of the rocky habitat (Ref. 5595, 55925), the intermediate habitat, over sand, and in the open water (Ref. 5595). Feeds on plankton (Ref. 5595).
