Measurements (n= 42): antennomeres length: 1st: 0.50–0.55mm; 2nd: 1.07–1.20mm; 3rd: 1.61–2.12mm; 4th: 2.61–2.98mm; 5th: 3.61–3.70mm; head length: 1.49–1.54mm; head width: 2.60–2.70mm; pronotal length: 2.77–2.86mm; pronotal width: 7.22–7.91mm; scutellum length: 5.62–6.44mm; scutellum width: 4.47–4.83mm; abdominal width: 7.10–7.93mm; total length: 12.25–13.95mm.

Diagnosis: body dorsally green except brown corium ( Fig. 9 B). Antennae uniformly brown ( Fig. 9 B). Anterolateral margin of pronotum with narrow yellowish stripe ( Fig. 9 B). Minute longitudinal callosity adjacent to humeral angles ( Fig. 9 B). Humeral angles concolorous with dorsum, straight, short, about as long as the width of an eye ( Fig. 9 B). Corium mostly brown with diffuse yellowish to greenish color especially on basal third ( Fig. 9 B); veins yellowish, costal margin mostly green ( Fig. 9 B). Last connexival segment with dark narrow stripe on posterior margin ( Fig. 9 B). Ventral surface: green with median area yellow, without dark stripes, sometimes intersegmental areas of abdomen slightly darker ( Fig. 9 E). Anterior bifurcation of the metasternal process with arms short, wide, apices acuminated ( Fig. 6 F). Male genitalia: pygophore trapezoidal ( Fig. 6 A, B). Superior process of the genital composed by two parts: dorsal part triangular, concave and fused with dorsal rim ( Fig. 6 C, D), ventral part plain, rectangular and narrow placed ventrally to the dorsal part (barely visible on Fig. 6 D). Parameres very swollen, anterior lobe triangular and short ( Fig. 6 C, D); posterior lobe small, narrow and rounded ( Fig. 6 C, D); both lobes compressed and sulcate ( Fig. 6 C, D). Proctiger laterally excavated ( Fig. 6 C, D); posterior face rounded to subtriangular with median brown carina ( Fig. 6 C). Ventral rim with median notch shallow and wide ( Fig. 6 B). Female genitalia ( Fig. 6 E): valvifers VIII punctured, broadly and shallowly excavated distally, margin of the excavation brown.

Description: head: clypeus and jugae slightly transversely ridged. Bucculae subtriangular, neighboring first labial segment. Thorax: dorsal surface: pronotum with punctures very sparse and light-brown ( Fig. 9 B); anterior part of pronotum unpunctured, punctures disposed on posterior 3/4, mostly on medial region ( Fig. 9 B). Scutellum with punctures light-brown, very sparse on anterior half, grouped much tighter on posterior 2/3, faded on posterior ¼ ( Fig. 9 B). Corium with punctures brown ( Fig. 9 B). Membrane translucent, slightly dark ( Fig. 9 B). Ventral surface: prothorax–mesothorax irregularly punctured, punctures concolorous or light-brown, minute, sparse ( Fig. 9 E). Peritreme ruga-like, reaching 3/4 of the distance between ostiole of the scent gland and lateral margin of metapleuron ( Fig. 9 E). Metasternal process delicate, medially narrower; anterior arms slightly divergent, anterior bifurcation receiving only fourth rostral segment and a small portion of third ( Fig. 6 F). Abdomen: dorsal surface: connexival segments with posterolateral angles concolorous ( Fig. 9 B). Male genitalia: dorsal rim brown medially, setose ( Fig. 6 A). Posterolateral angles small, truncated, inner face excavated ( Fig. 6 A). Ventral rim with expansions inconspicuous ( Fig. 6 B). Female genitalia ( Fig. 6 C): valvifers VIII convex reaching base of valvifers IX, excavation exposing part of valvulae IX. Laterotergites VIII outer lateral margin strongly arched, sinuous; free distal spinose part about 1/5 of its length. Valvifers IX smooth, trapezoidal, widely exposed. Laterotergites IX barely projected distally, reaching or slightly surpassing sclerite uniting laterotergites VIII.

Differential diagnosis: the facies of E. helvoalata sp. n. is similar to E. bituberculata sp. n., E. bivenulata sp. n. and E. enargocelida sp. n., but the green costal margin of E. helvoalata clearly separates them ( Fig. 9 B) (brown margin in the other species— Fig.8 A, B, C). Furthermore, the ventral surface of E. helvoalata sp. n. does not present dark stripes ( Fig. 9 E) (present in the other species— Fig. 8 D, E, F).

Distribution ( Fig.10 C): COSTA RICA: Guanacaste, Alajuela, Puntarenas, Cartago; PANAMA: Colón, Panamá.
