Length 4.0 mm, width 2.3 mmbody form elongate, robust, widened from elytral base to apical 1/3 ( Fig. 15A). Color yellowish brown. Head with clypeal surface finely rugose with small, sparse tubercles extended onto frons, frons finely rugose, vertex finely rugose without basal carina, setae short, indistinct. Clypeal apex slightly raised, weakly sinuate with median emargination, lateral angles angulate ( Fig. 15B). Mandible pair symmetrical; mesal tooth strong; lateral prominence weak, outer margin abruptly rounded. Pronotum with distinct, 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, distinct central furrow extended from base to transverse furrow; surface finely rugose, with sparse, straight setae-bearing carinae, setae decumbent, about 1/2 length of carina; anterior and lateral pronotal margins not bordered, all margins crenulate. Elytra with surface dull, finely microreticulate; all striae convex, weakly carinate, carinal segments small, widely separated, not much more than setal bases, seta much longer than base; intervals with large, shallow, slightly rectangular punctures ( Fig. 15C). Metasternum long, dull, finely, densely microreticulate, median surface without ridges, laterally with scattered, straight ridges in basal 2/3, median area flat, with trace of median carina extended anteriorly from apical keel 1/2 distance to mesocoxae ( Fig. 15D); metasternal groove shallow, clearly demarked. Lateral protibial teeth unevenly spaced, basal 2 teeth closer together. Mesotibia with 6 spines laterally, spinal bases close together, tibia slightly projecting at apex ( Fig. 15D). Posterior metatrochanteral margin without small teeth; posterosuperior surface of metatrochanter with single tooth ( Fig. 15G). Metafemoral surface with widely, evenly spaced, setaebearing tubercles, microreticulate; width to length ratio 1.0:1.5, without noticeable flange on anterior margin; posterior metafemoral margin angulate next to trochanter; posterosuperior margin with 2 widely spaced teeth, outer tooth small ( Fig. 15G). Metatibia broadly triangular, surface entirely microreticulate, outer margin with series of small teeth from base to posteromedian lateral projection, projection small, oblique, surface smooth, median row of tubercles nearly lacking, inner margin smooth, pubescent ( Fig. 15F). Apical margin of male 5th abdominal ventrite feebly rounded. Genitalia long, basal piece about as long as parameres, proximal end curved; median lobe shorter than parameres, tapered from base to apex, narrower at middle than a paramere, slightly curved upward in apical 1/3, apex rounded in ventral view; parameres slightly curved before apex in lateral view, margin straight, apex narrowly rounded ( Fig. 15E).  Female. Apex of 5th abdominal ventrite strongly rounded.  Variation. Length 3.3 to 4.0 mm, width 1.8 to 2.3 mm. Number of lateral mesotibial spines varies from 6-8; number of tubercles and form of lateral projection on metatibia vary slightly, number of teeth on posterosuperior metafemoral surface varies from 1 to 2; posterosuperior teeth on metatrochanter vary from 1 to 2 closely spaced teeth.   Type material.  Holotypemale:  Utah: UTAH: ( Garfield Co.) 26 mi. S. Hanksville, Hwy.95, 16-VI-84, Robert Gordon( USNM).  Paratypes, 34: (15), same data as holotype; (1)  Utah, Emery Co., Little Gilson Butte,  29-VIII-1986, A.

Therefore the typeseries is restricted to sand deposits in the vicinity of Hanksville in Emery, eastern Garfield, and Wayne Counties. Specimens from Kane Co., Coral Pink dunes, differ from the typical by somewhat larger tubercles on clypeus and frons, and by distinctly more tubercles and more robust posteromedian projection of the metatibia. Specimens from dunes southeast of Boulder also have more prominent head tubercles, and the metatibial sculpture in some (not all) specimens is more pronounced than in Coral Pink specimens. However, all specimens examined have the shallow but distinctly defined metasternal groove that helps define  G. sabulosa. Southern Wyomingspecimens are distinctly larger and differ by having more prominent head tubercles, darker color, and slightly different metatibial posteromedian projection. The Wyomingspecimens are perhaps another species, but we are unable to satisfactorily distinguish them from Utah  G. sabulosaon morphological characters.   Glaresis inductais the most similar species, but has 4 or 5 metatibial spines; lacks a definable metasternal groove; body short, robust; and elytral carinae nearly continous. All typespecimens have been taken at light, and specimens collected by one of us (RDG) in the Hanksville area were at ultra violet light in blow sand deposits such as dunes and sand fields, etc. Nontype specimens were also taken in areas of sand deposits, all Wyomingspecimens were collected at UV light (R. Gordon, pers. obs.)   Etymology. The specific epithet is the Latin sabulosus, meaning sandy, referring to the extremely sandy habitat of this species. USNM S.
