Scolytinae - Scolytus rugulosus

Scolytinae - Scolytus rugulosus
Roseville, Vernon St., 38.7227, -121.2993. Elevation = 50m (164'), Placer County, California, USA
April 24, 2019
Size: 3.2 mm
Lindgren Funnel Trap. I Can't key to a genus that looks right. Help with ID would tell me where I'm making a mistake in Arnett's keys. I've been getting one or 2 of these every night in my trap whenever the temp is good around and after sundown this spring so it must be common.

Characters as I perceive them.
Head
-- Visible from above.
-- Eye is linear.
-- Antennal club has sutures that are procurved.
-- Can't determine how many segments are in the funicle.
Prothorax
-- Lateral ridge does not extend to the forward edge.
-- Looks like the indentations are longitudinally strigose.
Legs
-- Protibial curved process - can't find that it is bifid as the key asks for.
-- Picture is of the metatibia.
Abdomen
-- Anterior margins of elytra procurved, with large scutellum.
