Measurements (n= 8): antennomeres length: 1st: 0.50–0.54mm; 2nd: 1.23–1.33mm; 3rd: 1.46–1.71mm; 4th: 2.75–2.90mm; 5th: 3.10mm; head length: 0.99–1.28mm; head width: 2.41–2.43mm; pronotal length: 1.99–3.10mm; pronotal width: 6.59–7.20mm; scutellum length: 5.19–5.63mm; scutellum width: 3.97–4.01mm; abdominal width: 6.27–6.79mm; total length: 11.33–12.71mm.
Diagnosis: body dorsally green except variegated brown corium and yellow connexivum ( Fig. 1 A View FIGURE 1 ). Antennae brown, last segment with basal and distal parts whitish ( Fig. 8 A View FIGURE 8 ). Anterolateral margin of pronotum with narrow yellowish stripe ( Fig. 8 A View FIGURE 8 ). Pronotum and scutellum with punctures dark brown, irregularly distributed ( Fig. 8 A View FIGURE 8 ). Pronotum with small callosity adjacent to humeral angles bearing a tiny dark line ( Fig. 8 A View FIGURE 8 ). Ventral surface: yellow with faded to dark brown stripes on thorax and abdomen ( Fig. 8 D View FIGURE 8 ). Anterior bifurcation of metasternal process with arms short, thin, apices rounded ( Fig. 8 D View FIGURE 8 ). Male genitalia: pygophore subtrapezoidal ( Fig. 1 A, B View FIGURE 1 ). Posterolateral angles undeveloped ( Fig. 1 A View FIGURE 1 ). Superior process of the genital cup with blade-like dorsal part fused to dorsal rim, ventral tongue-like part free ( Fig. 1 C, D View FIGURE 1 ). Parameres with anterior lobe triangular, narrow, long, almost reaching dorsal rim; posterior lobe long and strongly curved ( Fig. 1 C, D View FIGURE 1 ). Proctiger laterally broadly and shallowly excavated ( Fig. 1 C, D View FIGURE 1 ); dorsal margin with conspicuously brown carina ( Fig. 1 C, D View FIGURE 1 ); posterior face triangular ( Fig. 1 C View FIGURE 1 ). Ventral rim with subrectangular median notch ( Fig. 1 B View FIGURE 1 ). Female genitalia ( Fig. 1 E View FIGURE 1 ): genital plates unpunctured. Valvifers VIII short with posterior margin acuminated.
Description: head: clypeus and jugae, slightly ridged. Bucculae subtriangular, harboring first labial segment.
Thorax: dorsal surface: humeral angles straight, about as long as the width of an eye ( Fig. 8 A View FIGURE 8 ). Scutellum with punctures larger and sparser on anterior half than on posterior half, unpunctured distally. Corium with parts of the veins, lateral margin and small spots yellow ( Fig. 8 A View FIGURE 8 ). Membrane transparent, brown ( Fig. 8 A View FIGURE 8 ). Ventral surface: prothorax and mesothorax with brown punctures ( Fig. 8 D View FIGURE 8 ). Propleuron with diffuse brown arched stripe between anterolateral angle and procoxal cavity ( Fig. 8 D View FIGURE 8 ). Mesopleuron with anterior transverse black stripe that curves and widens laterally ( Fig. 8 D View FIGURE 8 ). Peritreme ruga-like, reaching 2/3 of the distance between ostiole of the scent gland and lateral margin of metapleuron ( Fig. 8 D View FIGURE 8 ). Metasternal process with anterior arms slightly divergent ( Fig. 8 D View FIGURE 8 ); anterior bifurcation receiving only fourth rostral segment and a small portion of third ( Fig. 8 D View FIGURE 8 ). Abdomen: dorsal surface: posterolateral angle of connexival segments black ( Fig. 8 A View FIGURE 8 ); last connexival segment with distal black spot comprising less than half segment ( Fig. 8 A View FIGURE 8 ). Male genitalia: dorsal rim dark brown in a narrow area delimited by small tooth ( Fig. 1 A View FIGURE 1 ). Posterolateral angles truncated, slightly developed ( Fig. 1 A View FIGURE 1 ). Superior process of the genital cup black ( Fig. 1 C, D View FIGURE 1 ). Expansions of ventral rim not inconspicuous ( Fig. 1 B View FIGURE 1 ). Female genitalia ( Fig. 1 E View FIGURE 1 ): valvifers VIII with inner margins strongly and abruptly divergent towards apex, exposing valvulae IX. Laterotergites VIII acute distally, outer lateral margin softly arched; free distal spinose part about 1/5 of its length. Valvifers IX smooth and trapezoidal. Laterotergites IX slightly surpassing sclerite uniting laterotergites VIII.
Differential diagnosis: Edessa bituberculata sp. n. is very similar to E. bivenulata sp. n. ( Fig. 8A, B View FIGURE 8 ). However, E. bituberculata sp. n. has a large basal yellow area on corium ( Fig. 8 A View FIGURE 8 ) and mesothorax with dark punctures ( Fig. 8 D View FIGURE 8 ) while E. bivenulata sp. n. do not show these characteristics ( Fig. 8 B, E View FIGURE 8 ). Moreover, E. bituberculata sp. n. has the superior process of genital cup fused to dorsal rim ( Fig. 1 C, D View FIGURE 1 ) (free in E. bivenulata sp. n. — Fig. 2 C, D View FIGURE 2 ), subrectangular notch on ventral rim ( Fig. 1 B View FIGURE 1 ) (V-shaped notch in E. bivenulata sp. n. — Fig. 2 B View FIGURE 2 ), lateral excavation of proctiger larger than in E. bivenulata sp. n. ( Figs. 1 C View FIGURE 1 ; 2 C View FIGURE 2 ), and posterior face of proctiger smaller than in E. bivenulata sp. n. ( Figs. 1 C View FIGURE 1 ; 2 C View FIGURE 2 ). Females have valvifers VIII distal part of inner margins V-shaped while in E. bivenulata sp. n. they are U-shaped ( Figs. 1 E View FIGURE 1 ; 2 E View FIGURE 2 ).
Distribution ( Fig. 10 A View FIGURE 10 ): COSTA RICA: Puntarenas; PANAMA: Chiriquí.
