Genus Ramphomicron is a group of insects that belong to the family Cerambycidae. The insects in this genus are commonly known as flat-faced longhorns, due to their unique flattened heads. Some synonyms for the genus Ramphomicron include Megapenthes and Xylotrechus. These insects are usually found in the tropical regions of the Americas and are known for their distinctive markings and colors.
