Comments

Taxonomy from Grande & Bemis 1998.

Diagnosis for the subfamily from Grande & Bemis 1998, p. 450: "†Solnhofenamiinae subfam. nov. differs from all other amiid subfamilies (Amiinae, †Vidalamiinae subfam. nov., and †Amiopsinae subfam. nov.) in the following adult characters A and B. (A) There is only a single subinfraorbital, and it is slender and rod-like (versus either a series of two or more subinfraorbitals or a single deep subinfraorbital bone, in all other amiids). (B) There is a higher number of epaxial procurrent caudal fin rays than in any other amiid (12 to 15). Both A and B are discussed further on page 596 and pages 582 and 583 as characters 43 (character state 2) and 44. Also, like †Amiopsinae subfam. nov. but unlike Amiinae and †Vidalamiinae subfam. nov., †Solnhofenamiinae subfam. nov. has a suborbital bone and a relatively low number of dentary teeth in adult-sized individuals (12 to 13 versus 15 to 17 in adult-sized †Vidalamiinae subfam. nov. and 14 to 21 in adult-sized Amiinae)."

Diagnosis for the genus from Grande & Bemis 1998, p. 450: "As for subfamily (the subfamily contains only one genus with one species as used here)."
