Type species: Thorichthys ellioti Meek, 1904

Distinctive characters: Miller & Nelson (1961) deliminated Thorichthys from the other 'Cichlasoma' (Herichthys and Heros inclusively) by the following characteristics:

  • No scales on the basis of the soft part of the analis and dorsalis
  • Truncate to lunate caudal fin, the lobes of which are typlically produced into filaments in the adult
  • Extension of the pectoral fin backward to or usually well beyond the origin of the analis
  • Produced snout with the preorbital region typically very deep
  • Color pattern: 5 or six vertical bars behind the head (the first 4 prominent), the 3rd with a blackish blotch on or below the lateral line
  • A red (from salmon to rose) intermandibular region
  • Subopercle typically with a conspicuous blackish blotch
  • Head and anterior body parts usually with prominent blue spots
  • Consistent development of eight sensory pores (5 on the mandible) between the tip of the chin and the angle of the opercle

Further information: According to Hulsey et al. (2004), the genus Thorichthys is monophyletic. Miller & Taylor (1984) divided the genus Thorichthys in two groups of closely related species:

T. affinis-group T. helleri-group

T. affinis

T. helleri

T. meeki

T. aureus

T. pasionis

T. callolepis

T. ellioti (& T. sp. "Coatzacoalcos)

T. socolofi

Within the genus Thorichthys, there apparently are one or several undescribed species.
