Figure 20

Moore (1922) described Erpobdella punctata annulata from the vicinity of Vancouver,

Canada, and noticed that in the humid Pacific regions of Washington, Oregon, and

British Columbia this subspecies replaces the more common E. punctata punctata . The main morphological characteristic that dis-

tinguishes E. annulata from E. punctata is that the former has strongly pigmented dorsal transverse stripes (one on each annulus),

unlike the longitudinal pigmentation of E.

punctata sensu stricto or any of its variants

(see Madill and Hovingh, 2007). Oceguera-

Figueroa et al. (in review) suggested that the name E. annulata should be used for the transversally striped form from the Pacific FIGURES 20–22. Erpobdellids found in Washington Northwest.
