Parapsammodius

Parapsammodius species can be distinguished from related psammodiine genera by the combination of morphological characters established in the original generic description, including details of the clypeal structure and pronotal features. The genus is distinguished from Psammodius by characters related to the mandibular dentition and body proportions.

Members of the tribe Psammodiini, to which Parapsammodius belongs, are typically associated with sandy soils and psammophilous (sand-loving) environments. Specific microhabitat preferences for Parapsammodius species have not been documented in detail.

Nearctic and Neotropical regions. The genus includes species occurring in North America (P. bidens, P. puncticollis, P. integer) and at least one species described from material suggesting Neotropical distribution (P. pseudointeger).

• PsammodiusParapsammodius was separated from Psammodius based on distinct mandibular and clypeal characters; the two genera share psammodiine affinities and sand-associated habits but differ in specific structural features of the head and mouthparts.
