Fig. 16 View Figure 11-16 , 33 View Figure 32-33 ; Map 2

Description. Holotype, male. Measurements: head 0.34 long, 0.44 wide; pronotum 0.44 long, 0.48 wide; elytra 0.56 long, 0.36 wide; antennomeres 1-11 total 1.00; total length 2.14.

Head. Eyes large, maximum length in dorsal view equals length of first antennal segment, with approximately 40 facets. Antennomere 2 approximately 3/4 width of 1; 3 smallest.

Thorax. Elytra with row of approximately 5 fine sutural foveae in basal 2/5; central row of three large foveae in basal 1/4. Presumed brachypterous.

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

Aedeagus. Asymmetrical. Left paramere: short; apical half bulbous, inner apical blade wide at base (apex possibly damaged in holotype); sub-apical lateral setose process with 5 stout setae, and 4 thick ventral setae. Endophallus: base of lateral digitate process wide, ventrad from right paramere, sharply curved dorsally; apical half sinuate, slightly recurved to left, apex blunt. Right paramere: elongate, blade like; dorsolateral setose process long with 5 thick setae along apex; lateral constriction at level of digitate process of endophallus shallow; distal 2/3 curved left, narrowed to acute apex. Scattered, sparse, fine tubercles on setose processes.

Type Material. Holotype, male: * USA: Tenn., Sevier Co., Gt. Smky. Natl. Pk., Clingman’s Dome nr. tower, 29–V–1982, FMHD #82–48, at stump, u. fern, W. S. Suter ( FMNH) (1M). Deposited in FMNH.  

Geographical Distribution. Sonoma mayori   is known from a single specimen collected near the tower at Clingman’s Dome in Sevier County, Tennessee within GSMNP at 2020 m elevation.

Comments. Sonoma mayori   was collected in June “at stump, u. [under?] fern”.

Aedeagal characters of Sonoma mayori   are similar to those of S. tridens   and S. nhunguyeni   . The left paramere of the holotype may be damaged apically, and if it possesses an elongate blade-like apex it could be similar to the left paramere of S. tridens   . However, the lack of a subapical dorsal shelf on the endophallus, the shallow constriction at the level of the digitate process of the endophallus on the right paramere, and the acute apex of the right paramere which extends distad of the endophallus in S. mayori   , will serve to distinguish it from S. tridens   . The lack of a dorsal lamina on the endophallus, and the acute apex of the right paramere extending distad of the endophallus of S. mayori   will serve to distinguish it from S. nhunguyeni   .

Etymology. This species was named for Adriean Johann Mayor, Museum Curator of the GSMNP Collection, melyrid specialist, and a participant in the Coleoptera   component of the All Taxa Biodiversity Inventory at GSMNP.
