Two new species of the mite family Erythraeidae (Acari: Prostigmata: Parasitengona) found associated with the spruce budworm, Choristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae), in Maine are described. Larvae of Leptus treati sp.nov. parasitize spruce budworm adults; L. treati is the first member of the genus to have both larval and postlarval instars described. Adults of Balaustium kendalli sp.nov. prey on spruce budworm eggs; B. kendalli is only the second member of the genus to have both larval and postlarval instars described.

Résumé

Deux espèces nouvelles de la famille Erythraeidae (Acari : Prostigmata : Parasitengona) associées avec la tordeuse des bourgeons de l’épinette, Choristoneura fumiferana (Clemens) (Lepidoptera : Tortricidae) à l’état de Maine, ont été décrites. Les larves de Leptus treati sp.nov. sont parasites des adultes de la tordeuse des bourgeons de l’épinette et cette espèce est la première du genre d’avoir eu décrit et les stades larvaires et le stade post-larvaire. Les adultes de Balaustium kendalli sp.nov. sont prédateurs des oeufs de la tordeuse des bourgeons de l’épinette et cette espèce n’est que la deuxième d’avoir eu décrit et les stades larvaires et le stade post-larvaire.
