Measurements: head 0.32 long, 0.35 wide; pronotum 0.42 long, 0.45 wide; elytra 0.60 long, 0.32 wide; antennomeres 1-11 total 0.95; total length 1.84.  Head.Eyes large, maximum length in dorsal view equal to length of first antennal segment, with approximately 20 facets. Antennomere 2 approximately 2/3 width of 1; 3 smallest.  Thorax.Elytra with row of 5 sutural foveae in basal 2/5, first fovea large; single fovea lateral and slightly basal to second sutural fovea; central row of 3 foveae in basal 2/5. Brachypterous.  Abdomen.Tergite one without transverse patch of microtrichia. No abdominal foveae. Basal pubescence present on all visible ventrites.  Aedeagus.Asymmetrical. Left paramere: swollen at base, lobed internally (scoop shaped); subapical setose process large, flattened, curved dorsomesad; 2 thick setae inserted on lateral margin; 4 thick setae inserted along obliquely truncate apex; large rounded mesal lobe; subapical shelf narrow and spine-like. Endophallus: lateral digitate process base as wide as endophallus base, ventrad of right paramere, sharply curved dorsally; large bulbous apex. Right paramere: dorsolateral setose process near base, long, with 5 apical setae; lateral constriction at level of digitate process of endophallus; apical 4/5 sinuate, apex acute. Tubercles on parameres fine and sparse, concentrated dorsally on left paramere, dorsomesally on right paramere.   Type Material.  Holotype, male: * U.S.A., TN, Sevier Co.GSMNP,  0.5 kmNE Newfound Gap, elv.  1600m 83 o24’46”W, 35 o38’9”N/ forest liter Berlese  26 June 2001 C.

One other specimen was collected approximately 30 kmwest at Beech Gap in GSMNP, Swain County, North Carolina. Specimens were collected between 1520 and 1650 melevation.   Comments.Specimens were collected in June, July, and October from leaf litter and rotten wood and extracted using a Berlese funnel.   Sonoma baylessaehas aedeagal characters unlike any other  Sonoma. The large rounded mesal lobe of the left paramere and the large bulbous apex of the endophallus serve to distinguish this species from all others in the genus.   Etymology.This species is named for Victoria“Vicky-Loo” Lynn Moseley Bayless, co-collector of the holotype, curator of the Louisiana StateArthropod Museum, and participant and co-PI of the Coleopteracomponent of the All Taxa Biodiversity Inventory at GSMNP. 2001-06-26 TN, V, GSNP, FMNH Berlese & C.
