Beltia nicaraguensis Jacoby 1881: 128  , by original description; Bechynĕ 1953: 192; Flowers 1996: 24. Holotype male at MCZ, seen, labeled: Chontales, Nicaragua. Janson//1st Jacoby Coll.//Type 9484.

Redescription. Male. Body ovate, length 5.7–7.3 mm. Head, pronotum, underside, and elytra metallic bright or olive green, often with a reddish purple reflexion; antennomeres 1–9 reddish brown, 10–11 often darker. Legs reddish brown ( Fig. 30View Figures 27–35).

Head. Clypeus coarsely punctate, punctures separated by distance less than their diameters. Frons with punctures separated by distance less than their diameters, surface between punctures smooth; vertex coarsely punctate, surface between punctures smooth.

Thorax. Prothorax distinctly wider than long, L/W = 0.69; pronotum widest behind middle; disc regularly, densely punctate, punctures separated by distance equal to or less than their diameters; surface between punctures shining. Front angles acute, directed anteriorly and down, not prominent. Prosternum with long setae, coarsely and rugosely punctate, expanded laterally behind coxae; posterior margin of intercoxal process weakly concave, width of intercoxal process 1.12× diameter of procoxa. Proepimeron coarsely and rugosely punctate. Mesosternum flat between coxae, surface punctate, with sparse setae. Metasternum with aciculate punctures forming a coarse reticulate pattern, with numerous short yellow setae; metepisternum with surface punctate. Profemur armed below with quadrate denticle in apical fourth ( Fig. 9View Figures 9–17).

Elytra. Coarsely punctate, punctures separated by distance subequal to their diameters, forming diagonal rugosities laterally; width across humeri 1.2× width across pronotum.

Abdomen. Sterna with scattered white setae longer in two submedian rows on sterna III–VI; sternum VII with a pair of weak depressions in center. Terga sclerotized, with row of fine spicules along base of terga II and III, and laterally on IV; terga V and VI with surface shagreened.

Genitalia. Median lobe ( Fig. 49aView Figures 42–49) with apex bearing an asymmetrical tubercle ( Fig. 49cView Figures 42–49); apical sclerite ( Fig. 49bView Figures 42–49) short, heavily sclerotized, with central groove.

Female. Body oval; length 7–8.1 mm; body and leg color as in male.

Head. Labrum, frons, clypeus, and eyes similar to male; antennae with apical segments shorter and more cylindrical than in male.

Thorax. Prothorax distinctly wider than long, L/W = 0.70; shape of pronotum as in male; prosternum similar to male, but width of intercoxal process 1.03× diameter of procoxa. Mesosternum, metasternum, and metepisternum as in male.

Elytra and scutellum as in male.

Abdomen with short setae, sternum VII with lateral margins smooth, apical margin with a small median tubercle and a pair of larger submedian tubercles; pygidium as in male.

Genitalia. Segments VIII–XI forming a moderately elongate (L/W = 4.0) ovipositor ( Fig. 66aView Figures 60–66). Sternum VIII with long, strap-like basal apodeme with apical end widened, a small membranous area in the center. Segment IX covered with minute setae; hemisternites with long basal rods, well sclerotized apically; baculum distinct, apical, shorter than gonocoxae; gonocoxae longer than broad. Spermatheca ( Fig. 66bView Figures 60–66) with receptacle short, cone-shaped, slightly narrower at base than pump.

Diagnosis. This species can be distinguished from all other Beltia  (and most other Neotropical Eumolpinae  ) by the quadrate apical teeth on the profemora ( Fig. 9View Figures 9–17). It can be further distinguished from the other two Beltia  species with toothed profemora ( B. tisingalita  and B. weyrauchi  , see below) by the more coarsely punctate pronotum.

Remarks. The female specimen from La Selva has the characteristic quadrate tooth on the left profemur only. This species is limited to an area including southern Nicaragua (the type locality) and across northern Costa Rica ( Fig. 81View Figures 80–82). The two specimens from La Selva were collected by canopy fogging.
