Measurements (n= 8): antennomeres length: 1st: 0.82–0.88mm; 2nd: 1.47–1.57mm; 3rd: 1.52–2.02mm; 4th: 3.73–4.26mm; 5th: 3.84–4.35mm; head length: 1.40–1.79mm; head width: 2.27–3.10mm; pronotal length: 3.12–3.36mm; pronotal width: 7.20–10.16mm; scutellum length: 5.54–6.22mm; scutellum width: 4.23–4.69mm; abdominal width: 7.02–10.08mm; total length: 12.22–17.38mm.

Diagnosis: body dorsally green ( Fig. 9 C). Antennae light-brown ( Fig. 9 C). Anterolateral margin of pronotum yellow ( Fig. 9 C). Black minute longitudinal callosity adjacent to humeral angles ( Fig. 9 C). Humeral angles concolorous with dorsum, straight, short, less than the width of an eye ( Fig. 9 C). Last connexival segment with only posterior margin black ( Fig. 9 C). Ventral surface: green with median area yellow, without dark stripes, intersegmental areas of the abdomen slightly darker than the rest ( Fig. 9 F). Anterior bifurcation of the metasternal process with arms very short, wide, swollen, apices rounded ( Fig. 9 F). Male genitalia: pygophore trapezoidal ( Fig. 7 A, B). Superior process of the genital cup subtriangular, surface rugose, slightly concave ( Fig. 7 C, D). Parameres with anterior lobe long and subtriangular ( Fig. 7 C, D); dorsal margin shallowly excavated ( Fig. 7 C, D); posterior lobe short and triangular ( Fig. 7 C, D). Proctiger laterally strongly excavated, separated by feeble low carina ( Fig. 7 C); posterior face rounded to slightly elliptic ( Fig. 7 C). Ventral rim with median notch shallow and wide ( Fig. 7 B); expansions slightly developed ( Fig. 7 B). Female genitalia ( Fig. 7 E): valvifers VIII punctured with wide and deep V-shaped excavation; inner margin overlapping each other.

Description: head: clypeus and jugae, slightly ridged. Bucculae subtriangular, completely harboring first labial segment. Thorax: dorsal surface: pronotum with punctures concolorous, sparse, mostly present on posterior ¾ ( Fig. 9 C). Anterior margin of pronotum with row of sparse punctures ( Fig. 9 C). Scutellum with punctures concolorous, sparse on anterior half, grouped much tighter on posterior half ( Fig. 9 C). Corium with concolorous punctures ( Fig. 9 C); membrane transparent, unpigmented ( Fig. 9 C). Ventral surface: prothorax–mesothorax irregularly punctured, punctures concolorous or dark ( Fig. 9 F). Peritreme ruga-like, reaching 4/5 of the distance between ostiole of the scent gland and lateral margin of metapleuron ( Fig. 9 F). Metasternal process with anterior arms slightly divergent, anterior bifurcation receiving only part of fourth rostral segment ( Fig. 9 F). Abdomen: dorsal surface: posterolateral angles of connexival segments with apices black ( Fig. 9 C). Male genitalia: dorsal rim with brown large spot that extends to dorsal surface ( Fig. 7 A); shallowly concave ( Fig. 7 A). Posterolateral angles well developed ( Fig. 7 A); rounded, slightly swollen ( Fig. 7 A). Ventral rim with expansions short, rounded, slightly swollen ( Fig. 7 B). Female genitalia ( Fig. 7 E): valvifers VIII convex reaching base of valvifers IX, excavation exposing part of valvulae IX. Laterotergites VIII acute, outer lateral margin arched, sinuous, free distal spinose part about 1/4 of its length. Valvifers IX gently punctured, trapezoidal. Laterotergites IX acute clearly surpassing sclerite uniting laterotergites VIII.

Differential diagnosis: among the species in this article, Edessa holochlorata sp. n. stands out for having a completely green corium ( Fig. 9 C), unlike the brown corium of all others ( Figs. 8 A, B, C; 9 A, B). Furthermore, male and female genitalia also present distinctive characteristics like the shape of the parameres and overlapping valvifers VIII ( Fig. 7 C, E).
