Etymology Noun in the genitive singular. Coilodes bezerrai Basílio & Vaz-de-Mello sp. nov. is named in honour of Dr. Eduardo Barbosa Bezerra, entomologist, and professor at Universidade Estadual da Paraíba , Brazil . He was the first advisor of the first author of this species. This honour is a way to immortalize a researcher and professor who unfortunately had his career interrupted, but who managed to perpetuate his teachings.
