; its small size, and thin, tapered form is distinctive within southeastern Nearctic worm samples. The male porophores are usually visible on unmounted, mature specimens. The position of the male pores on IX is anterior to that of most other lumbriculids (usually in X), but posterior to that of its congeners (VIII). Internally, the tubular atria with thick vasa deferentia (approximately the atrial diameter) separate this species from all other Nearctic lumbriculids.
