Glaresis montenegro Gordon and Hanley  , new species

Description. Male. Length 2.8 mm, width 1.6 mm; body form elongate, nearly parallel-sided, slightly widened in apical 1/2 ( Fig. 5AView Figures 5). Color yellowish brown. Head with clypeus and triangular median area on frons shiny, coarsely, densely tuberculate, remainder of frons and vertex dull, densely, finely rugose, setae on frons short, barely visible. Clypeal apex truncate, with small, dense, evenly spaced tubercles, appearing serrate, lateral angles oblique, pronounced, outwardly toothed ( Fig. 5BView Figures 5). Mandible pair symmetrical; mesal tooth strong; lateral prominence strong, pronounced; outer margin abruptly rounded. Pronotum with all foveae weakly impressed except fovea on each side medially near lateral margin strongly impressed; surface densely rugose, with sparse, setae-bearing carinae, carinae elongate, straight ( Fig. 5CView Figures 5). Elytra with surface dull, densely microreticulate; striae convex, strongly carinate, carinal segments briefly interrupted, each with short seta; intervals with small, shallow, mostly round punctures. Metasternum long, feebly shiny, finely, densely microreticulate, surface medially concave without median carina, lateral surface with short ridges in basal 2/3 ( Fig. 5DView Figures 5); metasternal groove broadly, shallowly impressed. Lateral protibial teeth unevenly spaced, basal 2 teeth close together. Mesotibia with 4 or 5 spines laterally, tibia strongly projecting at apex ( Fig. 5CView Figures 5). Posterior metatrochanteral margin without teeth, outer angle lacking tooth; posterosuperior surface of metatrochanter with single large tooth often visible directly in ventral view ( Fig. 5GView Figures 5). Metafemoral surface with widely scattered, small, obliquely transverse,setae-bearing tubercles, microreticulate; width to length ratio 1.0:1.6, with narrow flange on anterior margin, posterior margin without tooth; posterosuperior margin without tooth ( Fig. 5GView Figures 5). Metatibia broadly triangular, surface entirely microreticulate, outer margin without posteromedian projection, with series of small, subequal teeth from base nearly to apex, inner margin smooth, pubescent ( Fig. 5FView Figures 5). Apex of 5th abdominal ventrite slightly arcuate. Genitalia long, basal piece 1/2 as long as parameres, proximal end curved; median lobe shorter than parameres, nearly parallel-sided except narrowed medially, appearing “pinched”, apex rounded, wide, twice as wide as paramere at middle, curved upward before apex; parameres feebly curved in lateral view, apex bluntly rounded ( Fig. 5EView Figures 5).

Female. Apex of 5th abdominal ventrite truncate.

Variation. Length 2.7 to 3.2 mm, width 1.6 to 1.7 mm. Size of head tubercles slightly variable; clypeal apex occasionally with slight median emargination; mesotibia with 4 or 5 lateral spines.

Remarks. This is a small sister species of G. phoenicis  which it closely resembles. Glaresis montenegro  differs from G. phoenicis  by the smaller size, length 2.70 to 3.20 mm; truncate or nearly truncate clypeal apex; more strongly carinate elytral striae; lack of angulate tooth on posterior metafemoral margin near trochanter; apex of 5th female abdominal ventrite truncate; and male genitalia with basal piece wide, much shorter than parameres. See Remarks under G. yanegai  , new species.

The actual distribution of this species is unknown, but is probably severely restricted because the general geographic area has been heavily light trapped over the past 30 years.

Etymology. This species is named for the holotype locality which translates to “montenegro.”
