description: 1. <i>Sonoma agitator</i> new species Fig. 1, 43; Map 2. <b>Description.</b> Holotype, male. Measurements: head 0.24 long, 0.30 wide; pronotum 0.29 long, 0.35 wide; elytra 0.60 long, 0.30 wide; antennomeres 1–11 total 0.73; total length 2.01. Body uniformly pale brown. Body covered in elongate setae (greater than half the length of the eye). <i>Head</i>. Eyes prominent, maximum length in dorsal view 1.06x length of first antennal segment, with approximately 50 facets. Antennomere 2 approximately 0.73x width of 1; 3 smallest. <i>Thorax</i>. Elytra with indistinct sutural foveae; 2–3 foveae lateral to sutural fovea; central row of 5–6 foveae in basal 1/3. Winged. Metatrochanter rounded; metatibia with process on inner margin approximately halfway from base. <i>Abdomen</i>. Tergite IV with transverse patch of microtrichia narrowly interrupted at midline. Basal lateral foveae on ventrites V–VI only, reduced. Basal pubescence present on ventrites IV–VII. <i>Aedeagus</i>. Asymmetical. Left paramere: apical process with three elongate setae; inner subapical process thin, hooked dorsally, with three basal setae. Endophallus: with large, blunt, lateral basal process on left; width at midpoint greater than 1/3 width of left paramere; blunt apical and subapical processes. Right paramere: globose; with three apical and three subapical setae; ventral digitate process approximately 1/4 width of paramere; with acute mesad subapical process and reflexed apical process. <b>Type Material.</b> Holotype, male: * CA: Monterey Co. 36.0812°N, 121.5947°W UC Big Creek Reserve Big / Brunette Ck. confl. iii.28-iv.2.2004, FIT M.Caterino / CA BEETLE PROJ CBP0018666 (1&amp;male;).

Caterino / CA BEETLE PROJ CBP0094153 (SBMNH) (1&amp;male;). <b>Geographical Distribution.</b> <i>Sonoma agitator</i> is only known from two locations, one each in Monterey and San Luis Obispo counties, California. <b>Comments.</b> Specimens were collected during March through June using flight intercept traps. Aedeagal characters of <i>Sonoma agitator</i> are similar to those of <i>S. rubida.</i> The two can be separated based on the following characters, <i>S. rubida</i> in brackets []: endophallus with large lateral basal process on left [basal process wanting], width at midpoint greater than 1/3 width of left paramere [width less than 1/4 width of left paramere], apex blunt [apex narrowly pointed], with blunt subapical process [without subapical process]; right paramere ventral digitate process approximately 1/4 width of paramere [process approximately 1/6 width of paramere]. <b>Etymology.</b> The specific epithet celebrates the three separate times the author became deeply concerned that the species was <i>S. rubida</i> (on the grounds that the sketch in Marsh and Schuster 1962 was flawed), and the three separate times he discovered his own illustration of the aedeagus of <i>S. rubida</i> that not only vindicated Marsh and Schuster, but clearly showed <i>S. agitator</i> to be undescribed.
