Figure 34. BIOFAR records of Polycarpa pomaria.
recorded in the Arctic region (Árnbáck-Christie-
Linde, 1922). Dispersal into this region most likely
occurred via the North Atlantic Current.
P.pomaria and P. mamillarisare diíTicult to separate;
sec Vazquez et al. (1995) for a comparison between
these two species. I did not identify the P. pomaria
accotding to the instructions recommended by these
authors, tlius a re-examination is necessary to clarify
whether P. mamillaris is prcsent among the material.
