Identity and locality
Aphanotorulus cf. horridus / cf. emarginatus L108 (disputed)
Upper Rio Napo, Ecuador
Diagnostic evidence and naming
The L108 geographic fish is widely compared with Xingu L011 and Trombetas L116. Historical grouping is not proof of full molecular identity for all imported lots. A species-specific later catalog assigns Napo near Coca L108 to Aphanotorulus/Squaliforma cf. horridus rather than cf. emarginatus, contrary to older broad Red Fin Thresher grouping. This is a genuine competing taxonomic treatment, not a proven genetic reassignment of every L108 specimen.
Breeding and genetics limitations
A geographic trade alias alone cannot validate a captive founder or distinct inherited trait.
