🔬 Taxonomy
🐟 Physical Description
Diagnosis: Distinguished from T. quadrifilis in the alignment of the lateral margins of the head in the region from the anterior margin of the orbit to the posterior limit of the opercle (running approximately in parallel from ventral view vs. diverging laterally, respectively); in the body width at the pectoral-fin insertion as a proportion of the head width at the posterior margin of the orbit (0.99-1.10 vs. 1.17-1.25, respectively); in the distance from the tip of the snout to the anal fin origin (0.29-0.32 of SL vs. 0.33-0.36 of SL, respectively); and in the position of the anterior termination of the gill opening (one orbital diameter posterior of the transverse plane running through the posterior margin of the orbit vs. positioned in the transverse plane running through the center of the orbit, respectively) .
