Case 3871 – Cricosaurinae Koken, 1888 (Archosauria, Crocodylomorpha, Metriorhynchidae): proposed emendation to Cricosaurusinae to remove homonymy with Cricosaurinae Cope, 1875 (Lepidosauria, Squamata, Xantusiidae)

The purpose of this application, under Article 55.3 of the ICZN Code, is to remove the homonymy between the unused Cricosaurinae Koken, 1888 (Archosauria, Crocodylomorpha, Metriorhynchidae) (type genus Cricosaurus Wagner, 1858) and the in-use senior homonym Cricosaurinae Cope, 1875 (Lepidosauria, Squamata, Xantusiidae) (type genus Cricosaura Gundlach & Peters in Peters, 1863). We propose to emend the stem of the name of the type genus of the unused Cricosaurinae Koken, 1888 from Cricosaur- to Cricosaurus-, which would result in Cricosaurusinae Koken, 1888. Reversal of precedence (Article 23.9 of the Code) is invoked for the subjective synonymy between Cricosaurini Koken, 1888, herewith treated as a nomen oblitum, and Rhacheosaurini Young, Bell & Brusatte, 2011, herewith treated as a nomen protectum.
