Taxonomic history
The was erected by Paulsen in 2007 to accommodate previously placed in other genera, particularly Ochodaeus. This reclassification reflects ongoing refinement of phylogenetic relationships within Ochodaeidae.
Species diversity
The six described are: X. americanus (Westwood, 1852), X. luscinus (Howden, 1968), X. musculus (Say, 1835), X. planifrons (Schaeffer, 1906), X. simplex (LeConte, 1854), and X. ulkei (Horn, 1876). Species epithets date to 19th and early 20th century descriptions, indicating long recognition of these prior to generic reassignment.
