Glaresis View in CoL - Inducta Group

Description. Size moderate, length 2.6 to 4.3 mm. Clypeal apex slightly raised, weakly sinuate, medially emarginate ( Fig. 12B View Figures 12 ), clypeal surface and at least anterior portion of frons tuberculate. Pronotal fovea present but less pronounced than in mendica group. Elytral striae often not strongly carinate. Metasternal surface with ridges unmodified, metasternal groove not visible or difficult to detect (except G. canadensis , G. inducta and G. sabulosa ). Mesotibia with weak, blunt apical projection, posterolateral emargination with 4-6 or more spines. Mosterior metatrochanteral margin unarmed. Outer metatibial margin not apically incised, with major posteromedian lateral protuberance. Apex of 5th male and female abdominal ventrites sexually dimorphic, males with apex weakly rounded, nearly truncate, females with apex strongly rounded (except G. fritzi with apex slightly emarginate in both sexes).

Remarks. This group contains 6 similar appearing species, some of which are distinguished with difficulty. Unrecognized cryptic species may be present here because some widely disjunct distributions occur, as illustrated by G. canadensis and G. sabulosa . The one South American species is a reasonably typical member of the inducta group, although the armature of the posterior metatrochanteral and metafemoral margins is unusual.
