The labrum (upper lip) is not notched in the middle; the antennae are shorter than twice the width of the head; the maxillae on the underside of the head lack prominent rows of golden spines; the abdominal gills are rounded and similar to each other in structure; three long slender filaments at the end of the body are about equally long.[4]
