Figures 1–6

Description. Male holotype. Length 3.8 mm, width 2.0 mm; body form elongate, slightly widened from elytral base to apical 1/3 ( Fig. 1–2 ). Color dark brown, nearly black. Head surface densely microreticulate, strongly dull with shiny tubercles each bearing a single seta, separated by 2–3 diameters, tubercle diameters equal 1–2 ocular facets; setae short, barely visible medially, longer and distinct laterally and basally. Vertex with basal groove and carina complete from side to side, groove continuing laterally above eyes. Clypeal apex weakly emarginate medially, somewhat sinuate, with small, dense, evenly spaced tubercles, appearing serrate, without large tubercle on each side of middle, lateral angles sharply oblique, pronounced, lacking tooth ( Fig. 4–5 ). Mandible pair symmetrical; mesal tooth strong; lateral prominence weak; outer margin abruptly rounded. Pronotum with all foveae weakly impressed except fovea on each side medially near lateral margin strongly impressed; surface with straight setae-bearing carinae short, weakly raised; surface between carinae rugose and strongly microreticulate, dulled ( Fig. 5 ); carinae weakly raised, indistinct above lateral foveae. Elytra with surface dull, densely microreticulate; striae convex, feebly carinate, carinal segments widely separated, each with short seta; intervals with deep, circular to nearly rectangular punctures. Metasternum long, feebly shiny, densely microreticulate and rugose, surface medially flat with weak median carina on posterior 1/3, surface either side of glabrous middle with short seta bearing ridges; metasternal groove nearly invisible. Lateral protibial teeth unevenly spaced, basal 2 teeth close together. Mesotibia with 8 spines laterally, evenly spaced in posterolateral emargination terminating at base of strong apical projection ( Fig. 3 ). Posterior metatrochanteral margin strongly crenate, almost toothed ( Fig. 3 ); posterosuperior surface of metatrochanter with tooth. Metafemoral surface with widely scattered, elongate, setaebearing tubercles, strongly microreticulate; width to length ratio 1.0:1.5, with narrow flange on anterior margin; small blunt tooth at angle near trochanter; posterosuperior margin without teeth ( Fig. 3 ). Metatibia broadly triangular, surface rugose-microreticulate, outer margin evenly strongly crenate, lacking large teeth, inner margin smooth, pubescent ( Fig. 3 ). Apex of 5th abdominal ventrite truncate. Genitalia with basal piece slightly longer than parameres, proximal end curved; median lobe shorter than parameres, tapered from base to rounded apex, broad, about 1.5× width of paramere at middle, curved upward before apex; paramere weakly curved in lateral view, apex bluntly rounded ( Fig. 6 ).

Type material. Holotype male ( FSCA): Haiti: 5 mi. W. of / Ganthier by road / 26-XI-1970, J. H. Frank, / blacklight trap.

Etymology. This species is named for the collector of the species, J. Howard Frank, a close friend and colleague of Mike Thomas. They were both long-term members of the Editorial Board for Insecta Mundi from its early years until recently. Naming the two Glaresis species on Hispaniola for these two friends seems appropriate.
