10. Sonoma quellazaire new species

Fig. 10 , 25 ; Map 28.

Description. Holotype, male. Measurements: head 0.20 long, 0.28 wide; pronotum 0.28 long, 0.32 wide; elytra 0.50 long, 0.25 wide; antennomeres 1–11 total 0.58; total length 1.90. Body brown, maxillary palpi, antennae, and legs paler. Body with moderate length setae (approximately 1/2 or less width of eye).

Head. Eyes prominent, maximum length in dorsal view 0.87x length of first antennal segment, with approximately 30 facets. Antennomere 2 approximately 0.73x width of 1; 3 smallest.

Thorax. Pronotum with weak lateral discal foveae. Elytra with indistinct sutural foveae; 2 foveae lateral to sutural fovea; central row of 4 foveae in basal 1/3. Winged. Metatrochanter rounded; metatibia with small tubercle on inner margin near middle.

Abdomen. Tergite IV with transverse patch of microtrichia narrowly interrupted at midline. Basal lateral foveae on ventrites VI–V, weak on VII. Basal pubescence present on all visible ventrites.

Aedeagus. Left paramere: oval; subequal in width from base to apex; two large papillate processes and 4 short, thick setae clustered at apex. Endophallus: deflexed to right; apical 1/2 with 4 overlapping layers, third layer with thin, elongate double pronged posteriorly-directed process; ventral-most layer with thin triangular flange. Right paramere: teardrop-shaped; 3 short, thick setae at apex.

Type Material. Holotype, male: * USA: OR: Lane Co., Siuslaw N.F., Cummins Ck. Tr., 90-210m, 44°16.12’N, 124°05.89’W, 8.xi.2011, old-growth Picea sitchensis forest; FMHD#2011-002 , berl., leaf & log litter, M. Thayer & A. Newton; ANMT site 1235 (1♂). Deposited in FMNH.

Paratype (n=1). UNITED STATES: OREGON: Benton Co.: * USA: OR: Benton Co., Siuslaw N.F., Marys Peak, Meadowedge Tr. (W part), 1050-1070 m, 44°30.52’N, 123°33.56’W, 17.ix.2012, old growth Abies procera forest ; FMHD#2012-033 , berl., log & litter, A. Newton ; ANMT site 1204 ( FMNH) (1♂) SLIDE .

Geographical Distribution. Sonoma quellazaire is known from Benton and Lane counties, Oregon, but both locations are within the Siuslaw National Forest.

Comments. Specimens have been collected during September and November from Berlesed log and leaf litter material taken in old-growth Abies procera and Picea sitchensis forests at elevations ranging from 90–1070 m.

Aedeagal characters of S. quellazaire are similar to those of S. petersi . The left parameres of each are indistinguishable, but unique among known species of Sonoma . The two can be separated based on the following characters, S. petersi in brackets []: endophallus with four distinct horizons, right lateral apical corner acute, elongate posteriorly-directed process double pronged [endophallus with two horizons, right lateral apical corner rounded, posteriorly directed process with single tip]; right paramere teardrop shaped [right paramere round].

Etymology. The apical process of the endophallus is reminiscent of a cigarette holder with its cigarette, an image typified by Audrey Hepburn in the movie Breakfast at Tiffany’s. “Quellazaire” is a neologism for “cigarette holder”.
