A NEW GENUS AND SPECIES OF TERRESTRIAL PLANARIAN (PLATYHELMINTHES; TRICLADIDA; TERRICOLA) FROM SCOTLAND, AND AN EMENDATION OF THE GENUS ARTIOPOSTHIA

Arthurdendyus albidus gen. nov., sp. nov. is described. Live specimens are up to 13 cm long, and uniformly creamy white. The ovaries are lateral to the male copulatory apparatus and the false seminal vesicles anastomose. There are two adenodactyls. The pharynx is of the ‘bell-shaped’ type. The species is assumed to be native to New Zealand, but has yet to be found there. Artioposthia triangulata and other species native to New Zealand are transferred to the new genus.
