The Haplotaxida are one of two orders within the annelid subclass Oligochaeta, the other being the Lumbriculida. [1] No real common name exists, but they are simply referred to as haplotaxids. Given that the other clitellatan annelids are embedded between and around the Haplotaxida and Lumbriculida, the traditional Oligochaeta are a ...

Hirudinea is monophyletic, but the clade is embedded among the Oligochaeta. Two approaches are possible: [11] abolish Oligochaeta as traditionally delimited in favor of a number of smaller monophyletic lineages [11] treat Oligochaeta and Clitellata as synonymous while splitting up the traditional "oligochaetes" into monophyletic lineages.
