Miloderes

Members of Miloderes can be distinguished from other broad-nosed weevils by combination of characters typical of the tribe Byrsopagini, including the broad, short rostrum and associated mouthpart orientation. Specific species-level identification requires examination of genitalic characters and comparison with type specimens; several species were described relatively recently (2015) and are distinguished by subtle morphological differences in body form and setation.

Species occur in xeric and semi-arid environments of the western United States, including desert mountain ranges and adjacent valleys. Specific habitat associations include sagebrush steppe, pinyon-juniper woodland, and Mojave Desert scrub communities.

Western United States, with records from California, Nevada, and adjacent regions. Species have been described from specific localities including the Panamint Mountains, Mercury, Nevada, and the Amargosa Desert region.
