Extract

The genus Anoplonyx Marlatt belongs to the more generalized of the Nematinae and is clearly defined taxonomically by Ross (1937). This genus is comprised of very few known species, four in North America and four in Europe; all are associated with trees of the genus Larix. The species are similar in appearance and difficult to distinguish, especially in the adult stage.

Considerable confusion existed concerning the identification of the members of this genus in North America up until Wong (1955) published a key to separate the late feeding stages of Anoplonyx larvae found in Canada. The two species dealt with herein are apparently native to Eastern Canada and have generally been identified as one species, “Marlatt's Larch Sawfly”, A. laricis (Marlatt). Here they are identified as A. luteipes (Cresson) (= laricis Marlatt), and A. canadensis Harrington, as listed bv Ross (1951).
