Key to species groups of American Glaresis

1. Surface of pronotum and elytra with small, widely spaced, round tubercles, each bearing long, semi-erect seta ( Fig. 1A ); posterolateral pronotal angle produced, flanged ( Fig. 1E ); South America ................................................................................ Glaresis - Pardoalcaidei Group

— Surface of pronotum and elytra with somewhat elongate tubercles, usually with ridges rather than tubercles; posterolateral pronotal angle not produced; north of Panama...................... 2

2(1). Clypeal apex straight, widely flattened, smooth, angled posteriorly ( Fig. 2B ); pronotal foveae completely lacking ( Fig. 2C ); metatibia deeply incised apically on inner and outer margins ( Fig. 2G ) ....................................................................................... Glaresis - Ecostata Group

— Clypeal apex usually medially emarginate or sinuate, not angled posteriorly; pronotal foveae distinctly visible or deeply impressed; metatibia not incised apically on inner and outer margins ..................................................................................................................................................... 3

3(2). Pronotal fovea deeply impressed ( Fig. 27C ); elytral striae strongly, nearly continuously carinate ( Fig. 21A ); metatasternal groove distinct, shallow or deep ( Fig. 21D , 27D ); posterolateral emargination of mesotibia with 3 or 4 short, widely spaced spines ( Fig. 28D ) ......................... ........................................................................................................ Glaresis - Mendica Group

— Pronotal foveae weakly impressed ( Fig. 13C ) or strongly impressed (inducta group); elytral striae rounded or weakly carinate (except G. inducta and G. canadensis ); metasternal groove indistinct or not discernable (except G. sabulosa ); posterolateral emargination of mesotibia with more than 4 or more spines, spines usually long ............................................................................... 4

4(3). Clypeal apex flat ( Fig. 7B ); Mesotibial apex strongly produced, apex somewhat acute (except G. clypeata ) ( Fig. 8D ); posterior margin of metafemur usually with tooth or angulation next to trochanter ( Fig. 7G ) ................................................................... Glaresis - Phoenicis Group

— Clypeal apex narrowly, weakly raised ( Fig. 17B ): Mesotibial apex weakly produced, apex rounded ( Fig. 17D ); posterior margin of metafemur without tooth or angulation next to trochanter ( Fig. 17G ) ........................................................................................ Glaresis - Inducta Group
