Neopsammodius

Members of Neopsammodius can be distinguished from related psammodiine genera by the combination of taxonomic characters established in Rakovič's 1986 revision, though specific diagnostic features require examination of genitalia and other detailed morphological traits. The genus is separated from Psammodius and other close relatives based on structural differences in the male genitalia and body proportions. Identification to species level requires reference to the original descriptions by Fall, Cartwright, Bates, Say, and Horn.

Species in this genus are associated with sandy substrates, consistent with the ecological preferences of the tribe Psammodiini. Specific habitat associations for individual species include sandy areas in Texas and northeastern Mexico.

Nearctic and Neotropical regions. Species have been recorded from the United States (primarily Texas) and Mexico (including Coahuila and Veracruz).

• PsammodiusClosely related genus in the same tribe Psammodiini; Neopsammodius was established to accommodate species previously misclassified in Psammodius and related genera, distinguished by differences in male genitalia and body structure.
• AphodiusLarger genus in the same subfamily Aphodiinae; Neopsammodius species are smaller and more specialized for sandy habitats compared to the more generalized Aphodius.
