Taxonomic Remarks
Included in the synonymy of Iguanodectes tenuis (synonym of Iguanodectes spilurus) by Eigenmann and Myers (1929: 494) and subsequently confirmed by Böhlke (1954: 98 and 100). Revalidation is based on personal examination of the types of Iguanodectes rachovii and Iguanodectes spilurus.
