Identity and locality
Pterygoplichthys cf. gibbiceps L083; compare P. xinguensis
Rio Xingu basin, Brazil
Diagnostic evidence and naming
Independent detailed historical review warns against automatically synonymizing L083 with L165 gibbiceps: L083 Xingu sailfin specimens are reported with a finer vermiculated/net pattern, and Weber described P. xinguensis from this basin. Correct identity remains under review.
Breeding and genetics limitations
Photograph, museum diagnosis and exact locality needed; common sailfin trade is not a verified breeding lineage.
