Description. Holotype, male. Measurements: head 0.33 long, 0.40 wide; pronotum 0.42 long, 0.48 wide; elytra 0.55 long, 0.35 wide; antennomeres 1-11 total 0.94; total length 1.96.

Head. Eyes prominent, maximum length in dorsal view 1.2 x length of first antennal segment, with approximately 30 facets. Antennomere 2 approximately 7/12 width of 1; 3 smallest.

Thorax. Elytra with row of three sutural crenulations in basal third; row of 4 foveae in center 2/5, distance from first to second twice distance from second to third. Brachypterous.

Abdomen. Tergite one without transverse patch of microtrichia. No abdominal foveae. Basal pubescence present on all visible ventrites.

Aedeagus. Compact; apex of endophallus extending beyond parameres. Left paramere: base wide; parallel sided in basal half; apical half with wide, thin mesal blade; cluster of 6 thick elongate setae 1/3 from apex. Endophallus: basal 2/3 extremely asymmetrical; lateral digitate process at base 2/3 width of endophallus base, ventrad from right paramere; subapical shelf-like process directed ventrad; tip bowed, strongly curved right with expanded apex. Right paramere: base enlarged, rounded laterally; dorsolateral setose process short, rounded, with 4 setae along apex; lateral constriction at level of digitate process of endophallus; distal 1/3 as wide as left paramere, with straight outer margin; apex obtuse with blunt subapical hook mesad. Tubercles sparse, fine, scattered along mesal basal half of dorsal faces of both parameres.

Geographical Distribution. Specimens have been collected from four locations in Sevier and Cocke counties in the Tennessee side of GSMNP and from one location south of the park in Jackson County, North Carolina.

Comments. Specimens have been collected during March-July, and October from litter and coarse woody debris decay class 3-4 and 5. Berlese funnels and emergence traps were used as a collection technique. Two specimens were collected with pitfall traps; one set from February through early March, and the other set from early to late June.

Aedeagal characters of Sonoma gimmeli are similar to those of S. chouljenkoi . The wide lateral digitate process and subapical shelf of the endophallus, and width of the right paramere of S. gimmeli will serve to separate it from S. chouljenkoi .

Etymology. This species is named for Matthew Lincoln Gimmel, collector of the holotype specimen, phalacrid systematist, and participant in the Coleoptera component of the All Taxa Biodiversity Inventory at GSMNP.
