6. Oligonychus nielseni Reeves, 1963

Oligonychus nielseni Reeves, 1963: 57.

Host and distribution.

Pinus strobus ( Pinaceae ); United States.

Remarks.

Oligonychus nielseni Reeves was described from only females, and details of the male were absent in both the original ( Reeves 1963) and subsequent description ( Baker and Tuttle 1994). The species was not specifically compared with any other closely related Oligonychus species ( Reeves 1963). Moreover, variations have been reported in length of dorsocentral setae of the females from different populations, e.g., c1 reaching to bases of e1 ( Reeves 1963) or c1 shorter than the interval between c1-e1 ( Baker and Tuttle 1994). The species identity of O. nielseni will be resolved after collecting and describing the male from the type host and locality.
