Wilcox, 1972
Metapogon amargosae is a of robber fly ( Asilidae) described by Wilcox in 1972. It belongs to the Brachyrhopalinae, a group characterized by reduced wing venation and generally small to medium body size. The specific epithet references the Amargosa region, suggesting a geographic association with desert environments in the southwestern United States. Like other asilids, it is presumed to be an aerial , though direct observations of its remain limited.

Identification
Distinguished from other Metapogon by genitalic characters described in the original species description. Members of Brachyrhopalinae can be recognized by reduced R4+5 wing endings and generally shorter, more compact body proportions compared to other Asilidae . Species-level identification requires examination of male terminalia.
Habitat
Inferred from the specific epithet and distribution: likely associated with arid or semi-arid environments, including desert scrub and riparian corridors in the Amargosa River basin region.
Distribution
Type locality and primary distribution centered on the Amargosa region of southwestern North America, likely encompassing areas of Nevada and adjacent California.
