Etymology: Amblyrhynchotes: Greek, amblys = darkness + Greek, rhyngchos = snout (Ref. 45335). More on author: Bloch.
The species Torquigener marleyi (Fowler, 1929) is considered as valid in Eschmeyer (CofF ver. May 2011: Ref. 86870) following Heemstra & Heemstra (2004: Ref. 58304). The species page will be created.
