(Figure 12, Table 2)

Platystoma truncatum Six & Agassiz, 1829   ZBK : 27, pl. 13a. Type locality: Brazil, Japer and Solomon. Lundberg & Littmann (2003) considered this name to be a senior synonym of P. tigrinum   ZBK , based on the original description, plate, and locality. These authors retained the younger name P. tigrinum   ZBK for purposes of stability. There has been virtually no use of P. truncatum   ZBK since its original description, and it is treated here as a nomen oblitum (sensu Lundberg & Littmann, 2003).

Diagnosis: A species of Pseudoplatystoma   ZBK distinguished by a combination of the following features: presence of loop-like bands connecting to, or extending to, dorsal region and continuing onto other side of body; loop-like bars form cells as noted in the original description (Cuvier & Valenciennes, 1840). This unique feature allowed for the specific epithet of "tigrinum" because of the evident resemblance to the "Royal Tiger" (see Cuvier & Valenciennes 1840, p. 11); adipose fin with small spots and some loop -like bands; no discrete dark spots on side of body.

Description: Maximum size recorded 1300 mm TL. Head moderately narrow with a long fontanel extending from mesethmoid to supraoccipital. Body widest measurement at origin of dorsal fin. Loops covering sides and top of body and not extending beyond middle lateral region of body. No spots, straight or loop - like bars on dorsal region of head. Pigmentation on ventral region of body ranging from whitish to yellowish. Spots on dorsal fin rays relatively larger than other species. Spots on the caudal fin more numerous (50-60 in P. tigrinum , 21-45 in P. punctifer ; Figs. 13 and 14). Additional differences are described and compared with the other species in Table 9. Color and pattern of adults are shown in Fig. 15.
