Remarks. Rayforstia scuta is an unusual, widespread species from the North and South Islands of New Zealand. It is most similar to the other six-eyed species of Rayforstia described from New Zealand ( R. plebeia , R. propinqua , R. salmoni and R. wisei ), but can be distinguished by the distinctive shape of the male anterior sclerite, which extends posteriorly well beyond the epigastric furrow (see Forster 1959, fig. 46).
