provided a synoptic table for most species of the genus, which includes five morphological characters (numbers of branchial filaments on each branchial segment, the presence/absence of eyespots, number of pairs of notopodia, and dental formula of anterior and posterior tori). However, some of those characters are relatively unstable such as eyes may fade after preservation, number of pairs of notopodia based on incomplete specimens, or uncinial dental formula described were without using high resolution or scanning electron microscopes.
