Prateus
J.L. LeConte, 1862
Species Guides
1Prateus is a of darkling beetles in the Tenebrionidae, Lagriinae, and the type genus of the tribe Prateini. It was established by John Lawrence LeConte in 1862. The genus is part of the diverse tenebrionoid lineage, which includes many adapted to arid and semi-arid environments. Species within Prateus share characteristics with other lagriine beetles, though specific diagnostic features for the genus require examination of morphological details such as antennal structure and body form.

Identification
Members of Prateus can be distinguished from other Lagriinae by tribal characteristics of the Prateini, including specific arrangements of antennal segments and features of the pronotum and . Accurate identification to level requires reference to original descriptions and taxonomic revisions, as the genus has not been comprehensively revised in modern literature. The genus is most readily recognized by its placement within the morphologically cohesive Prateini tribe.
Distribution
of Prateus occur in North America, with records from the southwestern United States and Mexico. The appears to be restricted to the Nearctic and northern Neotropical regions, though precise range boundaries for individual species remain poorly documented.

More Details
Taxonomic history
The Prateus was established by J.L. LeConte in 1862 and has remained relatively stable in its tribal placement, serving as the type genus for Prateini. The tribe Prateini is one of several within the speciose Lagriinae, which contains hundreds of worldwide. Modern molecular phylogenetic studies of Lagriinae are limited, and the relationships among Prateini genera remain to be fully resolved.
Research needs
The Prateus would benefit from comprehensive taxonomic revision, including -level phylogenetic analysis and documentation of natural history traits. Basic information on associations, larval development, and feeding is largely unavailable in published literature.
