Description, holotype female ( Fig. 3 View FIGURES 1 – 3 ). Length 4.2 mm, width 2.2 mm. Color dark reddish brown. Head with surface of clypeus with large tubercles separated by 1–3 diameters, frons with tubercles smaller and less dense. Clypeal apex emarginate, margin strongly beaded and anteriorly crenulate, lateral angles angulate. Mandible with apex strong but abraded, internal teeth indistinct, external marginal lobe near base rounded, slightly elevated. Pronotum with weak, almost indistinct, transverse depression in anterior ¼, only distinctly subfoveate behind eyes; fovea on each side at middle near lateral margin; distinct, broad median furrow extending from base to weak transverse anterior depression. Pronotal surface with sparse, setae-bearing, elongate tubercles; tubercles occasionally conjoined anteriorly, as long as setae; basal pronotal margin crenulate to subdentate, especially in lateral ¼. Elytra [left elytron with damage on disc] with striae flat, with small, round tubercles at setal bases; seta distinct, length less than width of rectangular interval punctures; interval punctures shallow and surface between almost coplanar with striae. Metasternum lacking metatibial furrow. Mesotibia with 5 spines in distal half, distinctly projecting at contiguous bases of spines 1–3 (mesotibia appearing toothed at middle); apex rounded. Posterior metatrochanteral margin crenulate with large, rectangular tooth before metafemur partially abraded; superior surface of metatrochanter unarmed. Metafemora with small tooth near trochanter, on left possibly abraded; superior surface unarmed; externally with tuberculate carina from strong median projection extending onto ventral surface uninterrupted ( Fig. 6). Metatibia triangular, external margin with distinct triangular projection at middle ( Fig. 9).

Variation. Paratypes: Length 4.0– 4.6 mm, width 1.9–2.6 mm. Color light or dark reddish brown. Head with surface of clypeus strongly abraded, obscuring tubercles and crenulation. Metatrochanteral tooth generally more distinct and rectangular. Abdomens missing on remaining Peruvian specimens, obscuring sex.

Distribution ( Fig. 10 View FIGURE 10 ; n = 6). CHILE (2): Arica: Arica ; Valle de Lluta. PERU (4): Tacna: Las Yaras.

Temporal distribution. November (4), February (1), March (1).

Etymology. The species is named in honor of my friend, Chilean field collecting comrade, and colleague, José Mondaca, Servicio Agrícola y Ganadero, Santiago, Chile, who was the first to publish on Glaresis from Chile. He has contributed greatly to the taxonomy of the Scarabaeoidea of southern South America and also to my research on Lucanidae and other Scarabaeoidea.

Remarks. This species is much larger than the two Argentinian species of this species group, a character that by itself is often useful in distinguishing North American Glaresis species. Combined with the widely disjunct distribution and morphological differences, it is clear that the species is distinct. Morphologically the most important characters are the much stronger external tooth on the metatibia ( Fig. 6) and its carina that continues onto the ventral surface. The elytral tubercles are not as elongate as in G. fritzi .
