Comments

Two of the original five male cotypes WILLISTON WI designated for Heteromeringia flavipesflavipes (as Heteroneura) (WILLISTON, 1896) have been identified as pale phase males of Craspedochaeta concinna (WILLISTON (WI, 1896). Of the remaining three male cotypes, one is here designated as the lectotype of H. flavipes . The single female cotype was not examined.
