Glaresis fritzi Martinez, Pereira, and Vulcano 

Glaresis fritzi Martinez,Pereira, and Vulcano 1961: 77  .

Description. Male. Length 3.2 mm, width 2.7 mm; body form slightly elongate, strongly widened from elytral base to apical 1/3 ( Fig. 14AView Figures 14). Color pale yellowish brown. Head with surface of clypeus, frons, and anterior portion of vertex slightly shiny, finely microreticulate, posterior portion of vertex more coarsely reticulate, clypeus and frons with small, sparse tubercles. Clypeal apex feebly sinuate, with small, evenly spaced tubercles, medially raised and angled posteriorly, lateral angles rounded then angulate at apex ( Fig. 14BView Figures 14). Mandible pair symmetrical; mesal tooth strong; lateral prominence weak, outer margin 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 dense, T-shaped, setae-bearing carinae, setae decumbent, about 1/2 length of carina ( Fig. 14CView Figures 14); anterior and lateral pronotal margins not bordered, all margins crenulate. Elytra with surface dull, finely microreticulate; all striae strongly raised, convex, not carinate, remnants of carinae reduced to setal bases, seta much longer than base; intervals with large, shallow, slightly rectangular punctures ( Fig. 14EView Figures 14). Metasternum long, dull, finely, densely microreticulate, median surface without ridges, laterally with scattered, straight ridges in basal 2/3, median area slightly convex, without median carina ( Fig. 14DView Figures 14); metasternal groove not visible. Lateral protibial teeth unevenly spaced, basal 2 teeth closer together. Mesotibia with 6 spines laterally, spinal bases narowly separated, tibia slightly projecting at apex ( Fig. 14DView Figures 14). Posterior metatrochanteral margin serrate, with large tooth near metafemur ( Fig. 14HView Figures 14); posterosuperior surface of metatrochanter without teeth. Metafemoral surface with widely, evenly spaced, strong setae-bearing tubercles, microreticulate; width to length ratio 1.0:1.5, without noticeable flange on anterior margin; posterior metafemoral margin with large tooth near trochanter ( Fig. 14HView Figures 14); posterosuperior margin without teeth. Metatibia broadly triangular, surface entirely microreticulate, with large, irregular, posteromedian lateral projection, row of rounded teeth on lateral margin from base to posteromedian projection, short row of small, obliquely transverse tubercles extended from base nearly to posteromedian projection medially, inner margin smooth, pubescent ( Fig. 14GView Figures 14). Apical margin of 5th abdominal ventrite barely perceptibly emarginate medially. Genitalia elongate, basal piece much shorter than parameres, basal lobe weakly narrowed from base to apex, apex imarginate medially ( Fig. 14FView Figures 14).

Female. Apex of female 5th abdominal ventrite distinctly emarginate.

Variation. Length 3.0 to 3.7 mm, width 1.7 to 2.0 mm. Clypeal apex with posteriorly angled margin simply widened, or narrowly triangular (outer ends not extending to lateral angle) or widely triangular (outer ends reach lateral angle), occasionally smooth completely lacking tubercles; lateral mesotibial spine number varies from 5 to 6; posterosuperior margin of trochanter may have 2nd tiny tooth; and surface of metatibia varies slightly in degree of sculpture.

Type locality. Argentina, Rio Negro, Lamarque.

Type depository. Unknown.

Temporal distribution. November-February.

Geographical distribution. ARGENTINA. Catamarca: Andalgala   ; Londres, 15 km SW of Belen   ; La Cíenaga, Belen   ; Rio Potrero , 65 km NE of Andalgala.  Rio Negro: Lamarque   .

Remarks. Glaresis fritzi  is distinguished from any other member of the inducta group by the pronounced metatrochanteral and metafemoral armature. In general appearance it is most similar to G. arenata  and G. zvirgzdinsi  .

Some specimens of G. fritzi  are labeled as “Pitfall trap, dry desert,.” or “Pitfall trap, creosote bush desert.”
