Description. Male. Length 2.8 mm, width 1.5 mm; body form short, robust, slightly widened from elytral base to apical 1/3 ( Fig. 26AView Figures 26). Color yellowish brown. Head with clypeal surface and frons densely rugose, with large, irregular tubercles scattered throughout, setae short, indistinct; vertex without basal carina, surface rugose, reticulate with large, irregular tubercles. Clypeal apex essentially truncate, with large, evenly spaced tubercles, lateral angles oblique, acute ( Fig. 26BView Figures 26). Mandible pair symmetrical; mesal tooth strong; lateral prominence strong, pronounced; outer margin slightly angulate. Pronotum with deep, long, transverse fovea in anterior 1/4 extended completely across pronotum, small slightly transverse fovea on each side of middle in anterior 1/2, wide, deep fovea on each side medially near lateral margin, deep central furrow extended from base to transverse furrow; surface densely rugose, with distinctly separated, setae-bearing carinae, carinae straight, setae decumbent, about 1/2 length of carina ( Fig. 26CView Figures 26); anterior and lateral pronotal margins not bordered, basal and lateral margins margins crenulate. Elytra with surface dull, densely microreticulate; all striae strongly carinate, carinae appearing continuous but narrowly interrupted adjacent to space between interval punctures, each carinal segment bearing an apical seta about 2/3 length of segment; intervals with deep round punctures. Metasternum long, dull, finely, densely microreticulate, median surface not tuberculate medially, with short, straight ridges not forming reticulate pattern, median area slightly depressed, with distinct median carina ex- tended anteriorly from apical keel 1/3 distance to mesocoxae; metasternal groove wide, deep, both sides ridged ( Fig. 26DView Figures 26). Lateral protibial teeth not evenly spaced, 2nd and 3rd teeth close together. Mesotibia with 4 short, widely spaced spines laterally, tibia slightly projecting at apex ( Fig. 26DView Figures 26). Posterior metatrochanteral margin serrate with 4 teeth; outer trochanteral angle acute; posterosuperior surface of metatrochanter with 2 large teeth, 1 large tooth slightly visible directly in ventral view, teeth close together ( Fig. 26GView Figures 26). Metafemoral surface with widely scattered, elongate, setae-bearing tubercles, microreticulate; width to length ratio 1.0:1.6, with wide flange on anterior margin; posterosuperior margin with single tooth. Metatibia triangular, surface entirely microreticulate, with small posteromedian lateral projection on lateral margin preceded by row of small, even teeth, an irregular row of sparse, coarse tubercles extended from base nearly to apex medially, inner margin smooth, pubescent ( Fig. 26FView Figures 26). Apical margin of 5th abdominal ventrite broadly, weakly emarginate, emargination barely visible. Male genitalia long, basal piece shorter than parameres, strongly curved, proximal end curved; median lobe shorter than parameres, narrower at middle than a paramere, slightly curved upward in apical 1/3, tapered from base to apex, apex rounded in ventral view; parameres curved in lateral view, slightly sinuate on inner margin, apex bluntly rounded ( Fig. 26EView Figures 26).

Female. Apex of 5th abdominal ventrite truncate.

Variation. Length 3.2 to 3.4 mm, width 1.7 to 1.8 mm. Teeth on posterosuperior margins of trochanter and metatibia usually easily visible in direct view, but occasionally reduced in size, not visible in direct view.

Type material. Holotype male: California: CALIF: Riverside Co., SE of Hemet, Bautista Cny. Site 2, blacklight 3-V-2004, Paulsen , Smith , & Hawks ( CASC)  . Paratypes, 3; (1) same data as holotype; (2)  : USA: CA: Riverside Co., Hemet , Bautista Canyon, 33 o 41.776N 116 o 51.191’W, 657 m, 3 MAY 2004, Bruyea, Hawks, Paulsen, Smith, Ocampo.

Other specimen: Riverside Co., Menifee Vly (hills on west end). ( UCRC)

Remarks. Glaresis bautista  is the 3rd species of subgroup C with 2 large teeth on the posterosuperior metatrochanteral margin. It is distinguished from the other 2 species by its relatively sparse pronotal and metasternal carinae; form of male genitalia; and geographical distribution.

Etymology. This species is named for the type locality, name used as a noun in apposition.
