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 View FIGURE 8 ). Antennae brown ( Fig. 8 C View FIGURE 8 ). Pronotum with punctures very sparse, minute and shallow ( Fig. 8 C View FIGURE 8 ). Anterolateral margin of pronotum with narrow yellowish stripe ( Fig. 8 C View FIGURE 8 ). Dark minute longitudinal callosity adjacent to humeral angles ( Fig. 8 C View FIGURE 8 ). Scutellum anterior half with light-brown punctures ( Fig. 8 C View FIGURE 8 ); distal half with light-brown to brown punctures ( Fig. 8 C View FIGURE 8 ). Scutellum with transverse diffuse faint brown stripe delimiting a greenish-yellow distal spot ( Fig. 8 C View FIGURE 8 ). Last connexival segment with more than distal half black ( Fig. 8 C View FIGURE 8 ). Ventral surface: pale yellow to yellow with transversal, narrow brown stripes on thorax and abdomen ( Fig. 8 F View FIGURE 8 ). Anterior bifurcation of the metasternal process with arms short, broad, apices acuminated ( Fig. 8 F View FIGURE 8 ). Male genitalia: pygophore subrectangular ( Fig. 3 A, B View FIGURE 3 ). Dorsal rim convex medially ( Fig. 3 A View FIGURE 3 ). Posterolateral angle slightly developed ( Fig. 3 A View FIGURE 3 ). Superior process of the genital cup small, reniform, and adjacent to dorsal rim ( Fig. 3 C, D View FIGURE 3 ). Parameres with anterior lobe broad truncated and dorsally carinated, posterior lobe short and somewhat curved ( Fig. 3 C, D View FIGURE 3 ). Proctiger barely laterally excavated ( Fig. 3 C, D View FIGURE 3 ); posterior face truncated and peer-shaped ( Fig. 3 C View FIGURE 3 ). Ventral rim with deep broad median notch, expansions slightly developed ( Fig. 3 B View FIGURE 3 ). Female genitalia with few clusters of punctures ( Fig. 3 E View FIGURE 3 ). Valvifers VIII with median narrow deep excavation ( Fig. 3 E View FIGURE 3 ).

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 View FIGURE 8 ); short, less than the width of an eye ( Fig. 8 C View FIGURE 8 ). Pronotum with concolorous to light-brown punctures ( Fig. 8 C View FIGURE 8 ). Anterior margin of pronotum unpunctured ( Fig. 8 C View FIGURE 8 ). 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 View FIGURE 8 ). Corium densely punctured ( Fig. 8 C View FIGURE 8 ); claval vein, basal spot and some venal branches yellowish ( Fig. 8 C View FIGURE 8 ). Membrane translucent, slightly dark ( Fig. 8 C View FIGURE 8 ). Ventral surface: Prothorax–mesothorax irregularly punctured, punctures concolorous or brown ( Fig. 8 F View FIGURE 8 ). Pleura, intersegmental region with subtle brown stripes, propleura with transversal brown stripe ( Fig. 8 F View FIGURE 8 ). Peritreme ruga-like, reaching 3/4 of the distance between ostiole of the scent gland and lateral margin of metapleuron ( Fig. 8 F View FIGURE 8 ). Metasternal process medially narrower; anterior arms slightly divergent, anterior bifurcation receiving only fourth rostral segment ( Fig. 8 F View FIGURE 8 ). Abdomen: dorsal surface: posterolateral angles of connexival segments with apices black ( Fig. 8 C View FIGURE 8 ). Male genitalia: dorsal rim light-brown ( Fig. 3A View FIGURE 3 ). Posterolateral angles mildly excavated ( Fig. 3 A View FIGURE 3 ). Ventral rim with expansions rounded, slightly swollen, level with posterolateral angles ( Fig. 3 B View FIGURE 3 ). Female genitalia ( Fig. 3 E View FIGURE 3 ): 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 View FIGURE 8 ) (all other species presented here have the pronotum speckled with well-marked punctures— Figs. 8 A, B View FIGURE 8 ; 9 A, B, C View FIGURE 9 ), scutellum marked with a brown spot on its posterior portion, delimiting a greenish-yellow spot ( Fig. 8 C View FIGURE 8 ) (brown spot shared only with E. fuscopunctata — Fig. 9 A View FIGURE 9 ), and a large black spot covering more than half of the last connexival segment ( Fig. 8 C View FIGURE 8 ) (the other species with half or less of the segment covered by a black spot— Figs. 8 A, B View FIGURE 8 ; 9 A, B, C View FIGURE 9 ).
