MP 64, BI 1, ML 85 ( Figs 1–3 , 9 ) ZooBank registration: urn:lsid:zoobank.org:act: 429CBD26- 08F8-4207-BB19-13F4260D7CFB . Type genus: Cathorops Jordan & Gilbert, 1883. Diagnosis Mesethmoid median portion very narrow (2,?> 0), state 1 in Notarius biffi , Notarius kessleri , and Notarius neogranatensis , and state 2 in Notarius cookei , Notarius grandicassis , and Notarius troschelii ; bony bridge formed by lateral ethmoid and frontal cylindrical and thin (16, 0> 1); otolith longer than wide (73, 0> 1); subvertebral process long and narrow (79, 0> 1); transcapular process forming a right angle in relation to body axis 86 (0> 1), state 0 in Notarius cookei and Notarius grandicassis ; exoccipital bony crest parallel to vertebral column and mesially folded (92, 1> 2), state 3 in Notarius . Ambiguous optimization: Frontal mesial laminar projection present (23, 1> 0); posterior cranial fontanel formed by frontals and parieto-supraoccipital (25, 1> 0); pterotic mesial border with parieto-supraoccipital longer than anterior border with sphenotic (36, 0> 1), reversed in Notarius ; vomer lateral processes very narrow (53, 0> 1), reversed in Aspistor ; otolith anteromesial process inconspicuous (72, 1> 0), homoplastic in Galeichthys ; dorsal crest of urohyal projected anteriorly (156, 0> 1), reversed in Notarius rugispinis , Notarius planiceps , and Notarius phrygiatus ; 14 or fewer ribs (213, 1> 0), reversed in Notarius ; seventh vertebra free from ventral superficial ossification (214, 0> 1). Included genera Notarius Gill, 1863 Cathorops Jordan & Gilbert, 1883. Remarks BI analyses and ML analyses did not recognize Aspistor as a valid genus as was reported by Marceniuk and Menezes (2007) and Marceniuk et al. (2012) on morphological evidence (see Notarius Remarks).
