(326PIbud) proisotoma buddenbrocki (Strenzke, 1954)

Proisotoma buddenbrocki was discovered as new to Britain on the shore of Loch Laidon by Nelson (1980). It is a small yellowish white species that reaches 0.7 mm in length. The eyes have 8+8 ocelli, the mucro has two teeth, the dens has five ventral setae and the ventral side of the manubrium bears 1+1 setae (Fig. 1). Abroad, this species has been found in the marine littoral zone so it could turn up in many more localities.
