Etymology: Trematochromis: Greek, trematos = hole + Greek, chromis, = a fish, perhaps a perch (Ref. 45335).
Issue
The correct allocation to Haplochromis or Ctenochromis is pending further taxonomic studies (Ref. 57075).

Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 16 - 18; duri punggung lunak (Keseluruhan (total)) : 8 - 10; Duri dubur: 3; Sirip dubur lunak: 7 - 8. Body deep and moderately compressed (Ref. 57075). Presence of a thick sensory canal on the six infraorbitals, with large openings that are widely separated from each other (Ref. 57075). Unicuspid outer and inner teeth on both jaws; outer teeth arranged in a single regular row; inner teeth smaller than outer teeth, arranged in three to six irregular rows on anterior part of upper jaw (Ref. 57075). Presence of 2 scale rows between upper and lower lateral lines (Ref. 57075). Scales ctenoid on flank; cheek scaled; dorsal and anal fins with scales at base; caudal fin with small scales anteriorly on fin membranes between rays; paired fins without scales (Ref. 57075). Upper lateral line high on body with 21-25 scales, lower lateral line running along body axis with 11-16 scales, two pored scales anteriorly on caudal fin (Ref. 57075).
The mouth is very protrusable which favor the idea of a planktonic diet (Ref. 7343).
