Systematics: Lepidosaphes pseudotsugae is related to L. machili, but differs as follows: body narrower, gland tubercles fewer, lateral spurs pointed, sclerotized, dorsal ducts slightly stouter, submedian dorsal ducts wanting on the 2nd abdominal segment, perivulvar pores fewer, median lobes somewhat smaller, not notched (Takahashi, 1957b).
Structure: Adult female body with a deep constriction between meso- and metathorax. Marginal tubercles with single very prominent spine present on II to IV abdominal segments; sometimes, some of the spines bifurcated or notched (Danzig, 1980b).
Biology: Second stage nymphs hibernate (Danzig, 1980b). This species was collected at an altitude of 1000 meters (Takahashi, 1957b).
