Semanotus ligneus thujae Van Dyke, 1927: 103

Material examined. 100 males, 111 females, 82 sex undetermined.

Diagnosis. This subspecies can be separated from other subspecies of S. amplus by the following combination of characters: elytral base and humeral angles darkened, humeral angle extending further along the length of the elytra (sometimes to near ½) which makes the elytra appear longer and more convex.

Hosts. Thuja plicata (western red cedar).

Flower and Associated Vegetation Records. Pseudotsuga sp., Chaemycparis nootkatensis (yellow cedar), Sequoia sp., Abies concolor (white fir), Libocedrus decurrens (incense-cedar).

Distribution. Northern British Columbia to central California.

Remarks. Populations of this subspecies are very similar in appearance to S. amplus amplus , and may be just a color variation. This subspecies is often confused with aberrant specimens of S. terminatus and S. conformis .
