2. Oligonychus primulae (Oudemans, 1931)

Paratetranychus primulae Oudemans, 1931: 291.

Host and distribution.

Primula obconica ( Primulaceae); Netherlands.

Remarks.

Oligonychus primulae (Oudemans) was very poorly described using only the female, without illustrations, and the male was unknown in both the original (Oudemans 1931) and subsequent descriptions (Geijsks 1939; Pritchard and Baker 1955). Furthermore, Oudemans (1931) did not compare it specifically with any closely related species, except mentioning the resemblance of its empodium with O. ununguis (Jacobi, 1905) (described from Germany on Picea abies, Pinaceae). Pritchard and Baker (1955) confirmed it to be an Oligonychus, but highlighted its taxonomic position as doubtful due to the absence of the male. The identity of O. primulae is uncertain until the male and female are comprehensively described from the type host and locality.
