Comment: This species is listed as Xanthodius americanus (Saussure, 1858) in Felder et al. (2009) with comments on the taxonomic status of Xanthodius parvulus (Fabricius, 1793) and Xanthodius americanus (Saussure, 1858) (note 421). Xanthodius americanus has been designated as the valid species by Guinot (1968) based on the remarks in Monod (1956). However, this opinion is not accepted by P. Davie (Pers. Com., 2017), with this recommendation, followed herein: ‘despite the fact that no one appears to have subsequently found and/or redescribed the types of Xanthodius parvulus, there does seem to be general agreement that the two species are definitely synonyms, and therefore simple priority must apply, thus Xanthodius parvulus (Fabricius, 1793) is the older and senior available name for Chlorodius americanus Saussure, 1857’.

Comment(s) on data
Felder et al., 2009, list Xanthodius americanus (de Saussure, 1858) as valid, with note 421: Recent records for this species continue to be reported under the names Leptodius parvulus (Fabricius, 1793), Xanthodius americanus and Cataleptodius parvulus (Fabricius, 1793), the latter two of which unfortunately both appear in McLaughlin et al. (2005); Guinot (1968a), in the course of revisions, assigned this species to Xanthodius, not to Cataleptodius, and treated Chlorodius americanus de Saussure, 1858, as its only unambiguously applicable senior synonym; records include ULLZ 7031 from the shoreline of Banco Nuevo off the northern coast of Yucatán, ID by D. L. Felder.
