Identification
Members of the Promecosoma can be distinguished from related clytrine genera by their overall body form and antennal structure. P. inflatum specifically may be recognized by the somewhat inflated or swollen appearance of certain body segments, as suggested by its epithet. Accurate identification to species level typically requires examination of genitalic characters and comparison with or authoritative descriptions. The genus is part of the diverse Cryptocephalinae, which are generally small to medium-sized leaf beetles with compact bodies and often brightly colored or patterned .
Distribution
The is recorded from Mexico and the state of Arizona in the southwestern United States. Distribution records in GBIF indicate presence in Middle America and North America, with the specific documented localities being Arizona (USA) and Mexico.
