Material examined. 401 males, 380 females, 121 sex undetermined.

Holotype. Male ( ZMUC), examined; labelled “// ZMUC 00022367”.

Diagnosis. This species can be separated from other species of Semanotus by the following combination of characters: color dark brown to black; elytra pale yellow except for black maculation in the form of one pair of medium sized spots and apical 1/3 of elytra, rarely with spots enlarged basally to form an oblong ‘tongue-like’ longitudinal band; mandible without median tooth; elytral punctation and pubescence distinct: pale setae restricted to pale areas where the punctation is larger and more widely separated, and dark setae restricted to dark areas where the punctation is smaller, and almost contiguous (in the rare case when the basal area of the elytra is dark, the pubescence remains pale), pubescence semi-erect to decumbent; elytra with erect setae along suture usually only in basal ½; ventral pubescence white to grey, semi-erect to decumbent, fine, sparse, surface of ventrites not obscured.

Hosts. Thuja occidentalis L. (eastern white cedar), Cupressus sp., Juniperus sp.

Flower and Associated Vegetation Records. Pinus sp., Juniperus sp.

Distribution. Eastern Canada and USA, south to Oklahoma and eastern Texas.

Remarks. The current definition of S. ligneus as treated here is much more limited than the species concept of previous authors, as a number of subspecies have been removed from synonymy and have been given species status. The holotype of Anocomis lignea parvicollis is a smaller specimen of S. ligneus ; it has yellow setae in the pale areas of the elytra and the elytra pale yellow which is typical of S. ligneus .
