Measurements (n= 13): antennomeres length: 1st: 0.40–0.50mm; 2nd: 1.14–1.71mm; 3rd: 1.05–2.12mm; 4th: 2.17–2.27mm; 5th: 2.28–2.33mm; head length: 1.03–1.24mm; head width: 2.27–2.43mm; pronotal length: 2.36–2.42mm; pronotal width: 5.82–6.34mm; scutellum length: 4.44–5.03mm; scutellum width: 3.58–3.91mm; abdominal width: 5.49–5.52mm; total length: 11.12–11.45mm.
Diagnosis: body dorsally green, except variegated brown and yellow corium (Fig. 8 C). Antennae brown (Fig. 8 C). Pronotum with punctures very sparse, minute and shallow (Fig. 8 C). Anterolateral margin of pronotum with narrow yellowish stripe (Fig. 8 C). Dark minute longitudinal callosity adjacent to humeral angles (Fig. 8 C). Scutellum anterior half with light-brown punctures (Fig. 8 C); distal half with light-brown to brown punctures (Fig. 8 C). Scutellum with transverse diffuse faint brown stripe delimiting a greenish-yellow distal spot (Fig. 8 C). Last connexival segment with more than distal half black (Fig. 8 C). Ventral surface: pale yellow to yellow with transversal, narrow brown stripes on thorax and abdomen (Fig. 8 F). Anterior bifurcation of the metasternal process with arms short, broad, apices acuminated (Fig. 8 F). Male genitalia: pygophore subrectangular (Fig. 3 A, B). Dorsal rim convex medially (Fig. 3 A). Posterolateral angle slightly developed (Fig. 3 A). Superior process of the genital cup small, reniform, and adjacent to dorsal rim (Fig. 3 C, D). Parameres with anterior lobe broad truncated and dorsally carinated, posterior lobe short and somewhat curved (Fig. 3 C, D). Proctiger barely laterally excavated (Fig. 3 C, D); posterior face truncated and peer-shaped (Fig. 3 C). Ventral rim with deep broad median notch, expansions slightly developed (Fig. 3 B). Female genitalia with few clusters of punctures (Fig. 3 E). Valvifers VIII with median narrow deep excavation (Fig. 3 E).
Description: head: clypeus and jugae plain or with few very subtle transversal ridges. Bucculae subtriangular, harboring first labial segment. Thorax: dorsal surface: humeral angles with short, narrow, dark spot at the apex (Fig. 8 C); short, less than the width of an eye (Fig. 8 C). Pronotum with concolorous to light-brown punctures (Fig. 8 C). Anterior margin of pronotum unpunctured (Fig. 8 C). Scutellum with punctures light brown or concolorous with adjacent areas, very sparse on anterior half, concentrated on middle region, after brown spot almost unpunctured (Fig. 8 C). Corium densely punctured (Fig. 8 C); claval vein, basal spot and some venal branches yellowish (Fig. 8 C). Membrane translucent, slightly dark (Fig. 8 C). Ventral surface: Prothorax–mesothorax irregularly punctured, punctures concolorous or brown (Fig. 8 F). Pleura, intersegmental region with subtle brown stripes, propleura with transversal brown stripe (Fig. 8 F). Peritreme ruga-like, reaching 3/4 of the distance between ostiole of the scent gland and lateral margin of metapleuron (Fig. 8 F). Metasternal process medially narrower; anterior arms slightly divergent, anterior bifurcation receiving only fourth rostral segment (Fig. 8 F). Abdomen: dorsal surface: posterolateral angles of connexival segments with apices black (Fig. 8 C). Male genitalia: dorsal rim light-brown (Fig. 3A). Posterolateral angles mildly excavated (Fig. 3 A). Ventral rim with expansions rounded, slightly swollen, level with posterolateral angles (Fig. 3 B). Female genitalia (Fig. 3 E): valvifers VIII almost flat covering most of valvifers IX, distal margin sinuous; median excavation fairly exposing valvulae IX. Laterotergites VIII with outer lateral margin strongly arched; free distal spinose part about 1/3 of its length. Valvifers IX smooth, subtrapezoidal. Laterotergites IX acute, subtriangular, projected, far surpassing sclerite uniting laterotergites VIII.
Differential diagnosis: the identification of Edessa enargocelida sp. n. can easily be done based on the combination of pronotum almost smooth except for a few shallow punctures (Fig. 8 C) (all other species presented here have the pronotum speckled with well-marked punctures— Figs. 8 A, B; 9 A, B, C), scutellum marked with a brown spot on its posterior portion, delimiting a greenish-yellow spot (Fig. 8 C) (brown spot shared only with E. fuscopunctata — Fig. 9 A), and a large black spot covering more than half of the last connexival segment (Fig. 8 C) (the other species with half or less of the segment covered by a black spot— Figs. 8 A, B; 9 A, B, C).
Distribution (Fig. 10 B): COSTA RICA: Guanacaste, Alajuela, Limón, Puntarenas, San José, Cartago; PANAMA: Veraguas.
