Diagnosis |
T. purpureum and T. trilobatum have nearly identical initial phases (Ref. 1602). They differ slightly in details of the head markings, and T. purpureum has a slightly longer head, shorter pectoral fins, and attains a larger size (Ref. 1602, 48636). Females best distinguished by the 'V' mark on the snout (Ref. 48636). Initial phase with a vertical dark red line below front of eye usually with a branch to front of snout (Ref 9823). |
