Mastogenius
Mastogenius is a genus of minute jewel beetles (family Buprestidae) characterized by extremely small body size—adults measure approximately 2 mm in length. The genus contains approximately 40 described species distributed across the Americas, from the southwestern United States through Central America and into South America. Adults are typically collected by beating oak foliage, and at least one species has been recorded from Florida sand oak (Quercus geminata). The genus is among the smallest buprestids in North America, making field identification challenging without close examination.
