Description of male holotype. Length 5.0 mm. Head, pronotum, elytra, and underside and legs metallic green; antennomeres 1–4 reddish brown, 5–11 black ( Fig. 34 View Figures 27–35 ).

Head. Clypeus densely punctate, punctures separated by distance less than their diameters. Frons strongly punctate, surface between punctures smooth, vertex with median impressed line, punctures aciculate; antennal calli with fine punctulae, weakly swollen.

Thorax. Prothorax wider than long, L/W = 0.63; pronotum smooth, shining, sparsely and finely punctate. Prosternum with short white setae, coarsely punctate; posterior margin of intercoxal process truncate, width of intercoxal process 0.87× diameter of procoxa. Proepimeron with surface smooth, evenly, sparsely punctate. Mesosternum with anterior surface flat, surface sparsely punctate and weakly wrinkled. Metasternum smooth, metepisternum with surface finely granulate.

Elytra. Evenly punctate, punctures larger than those on pronotum, separated by distance greater than puncture diameter; width across humeri 1.4× width across pronotum; basal calli weakly developed; postbasal depression shallow.

Abdomen. Sterna with numerous setae; each segment with a submedian pair of long erect setae, surface of segments alutaceous. Terga with apex of segment IV and segments V and VI shagreened.

Genitalia. Median lobe relatively short, thick and bent downward in lateral view ( Fig. 54a View Figures 50–56 ); in en-face view broad, truncate, apicolateral margin sharply rounded, a nodule at middle of apical margin ( Fig. 54c View Figures 50–56 ). Apex of endophallus with a small, twisted apical sclerite ( Fig. 54b View Figures 50–56 ).

Female allotype. Length 6.0 mm (range 6.0– 7.1 mm). Head, pronotum, elytra, and underside and legs metallic green; antennomeres 1–4 reddish brown, 5–11 piceous.

Head. As in male.

Thorax. Prothorax wider than long, L/W = 0.59; pronotum with punctures stronger than in male, intercoxal process weakly concave, width of intercoxal process 1.1× diameter of procoxa. Mesosternum with anterior surface weakly convex. Metasternum and metepisternum as in male.

Elytra. Punctation as in male, width across humeri 1.3× width across pronotum; basal calli weakly developed; postbasal depression shallow.

Abdomen. Sterna with numerous short setae, surface of segments alutaceous. Tergum II with a basal row of small spicules.

Genitalia. Segments VIII–IX forming a short, broad ovipositor (L/W = 0.77; Fig. 69a View Figures 67–74 ); sternum VIII with Y-shaped basal apodeme; hemisternites relatively broad, with short basal rods, baculum broad, weakly sclerotized, subequal to gonocoxae. Gonocoxae short, robust, wider than long. Spermatheca with receptacle elongate, broadly fused to pump ( Fig. 69b View Figures 67–74 ).

Etymology. This species is named in honor of Maria Sanchez, formerly with INBio, who greatly assisted me and many other visiting taxonomists participating in INBio’s biodiversity projects.

Diagnosis. Beltia sanchezae is similar in appearance to the other small green species, B. awapita , B. confusa , B. herreri , and B. talaga . Beltia sanchezae can be separated from all these by its dark bluish green legs and black or dark brown apical half of the antenna. There is also a strong superficial resem- blance in color and form between B. sanchezae and Colaspoides batesi Jacoby ; the generic characters noted above will distinguish these two species.

Remarks. Beltia sanchezae is known from only a small area in the Talamanca mountain range near the Panama border ( Fig. 82 View Figures 80–82 ).
