Edessa bivenulata sp. n.

( Figs. 2 View FIGURE 2 ; 8 B, E View FIGURE 8 ; 10 B View FIGURE 10 )

Etymology. The name refers to the two small yellow veins in the corium.

Measurements (n= 6): antennomeres length: 1st: 0.56–0.61mm; 2nd: 1.25–1.47mm; 3rd: 1.68–1.79mm; 4th: 2.55–3.11mm; 5th: 2.72mm; head length: 1.21–1.54mm; head width: 2.53–2.78mm; pronotal length: 2.49–2.69mm; pronotal width: 7.51–8.22mm; scutellum length: 6.05–6.59mm; scutellum width: 4.37–4.93mm; abdominal width: 7.24–7.93mm; total length: 14.30–14.64mm.

Diagnosis: body dorsally green except brown corium ( Fig. 8 B View FIGURE 8 ). Antennae brown, 4th and 5th antennomeres with basal halves whitish ( Fig. 8 B View FIGURE 8 ). Anterolateral margin of pronotum with narrow yellowish stripe ( Fig. 8 E View FIGURE 8 ). Pronotum and scutellum with punctures dark brown, irregularly distributed ( Fig. 8 B View FIGURE 8 ). Pronotum with small callosity adjacent to humeral angles bearing a tiny dark line ( Fig. 8 B View FIGURE 8 ). Corium with basal, black, lateral stripe ( Fig. 8 B View FIGURE 8 ). Connexival segments with whitish medial spot. Ventral surface: yellow with brown narrow stripes on thorax and abdomen ( Fig. 8 E View FIGURE 8 ). Anterior bifurcation of metasternal process with arms short, broad, apices rounded ( Fig. 2 F View FIGURE 2 ). Male genitalia: pygophore subtrapezoidal ( Fig. 2 A, B View FIGURE 2 ). Posterolateral angles slightly developed ( Fig. 2 A View FIGURE 2 ). Superior process of the genital cup spearhead-shaped, bifid posteriorly ( Fig. 2 C, D View FIGURE 2 ). Parameres with anterior lobe subrectangular and short ( Fig. 2 C, D View FIGURE 2 ); posterior lobe short and curved ( Fig. 2 C, D View FIGURE 2 ). Proctiger laterally shallowly excavated ( Fig. 2 C, D View FIGURE 2 ); dorsal margin with broad, brown carina ( Fig. 2 C View FIGURE 2 ); posterior face triangular ( Fig. 2 C View FIGURE 2 ). Ventral rim with V-shaped median notch ( Fig. 2 B View FIGURE 2 ). Female genitalia ( Fig. 2 E View FIGURE 2 ): genital plates sparsely punctured. Valvifers VIII inner margins forming a deep U-shaped excavation.

Description: head: clypeus and jugae, slightly ridged. Bucculae subtriangular, harboring first labial segment.

Thorax: dorsal surface: humeral angles concolorous with dorsum, straight, about as long as the width of an eye ( Fig. 8 B View FIGURE 8 ). Scutellum with punctures sparser on anterior half than on posterior half ( Fig. 8 B View FIGURE 8 ). Corium with margin and two curved spots and parts of few veins yellow ( Fig. 8 B View FIGURE 8 ). Membrane transparent, brown ( Fig. 8 B View FIGURE 8 ). Ventral surface: prothorax with irregularly distributed and light brown punctures ( Fig. 8 E View FIGURE 8 ). Propleuron with dark brown arched stripe between anterolateral angle and procoxal cavity. Mesothorax unpunctured ( Fig. 8 E View FIGURE 8 ). Mesopleuron with thin black stripe on margin adjacent to propleuron and small black line close to coxa ( Fig. 8 E View FIGURE 8 ). Peritreme ruga-like, reaches 2/3 of the distance between ostiole of the scent gland and lateral margin of metapleuron. Metasternal process with anterior arms slightly divergent, anterior bifurcation receiving only fourth rostral segment ( Fig. 2 F View FIGURE 2 ).

Abdomen: dorsal surface: connexival segments with posterolateral angles black; last connexival segment with narrow distal black spot. Male genitalia: dorsal rim dark brown in an area delimited by indentation and coincident with parameres ( Fig. 2 A View FIGURE 2 ). Posterolateral angles truncated ( Fig. 2 A View FIGURE 2 ). Superior process of the genital cup dark brown ( Fig. 2 C, D View FIGURE 2 ). Expansions of the ventral rim slightly swollen ( Fig. 2 B View FIGURE 2 ). Female genitalia ( Fig. 2 E View FIGURE 2 ): valvifers VIII convex; lateral margin sinuous, excavation exposing valvulae IX. Laterotergites VIII distally sharp, outer lateral margin softly arched; free distal spinose part about 1/6 of its length. Valvifers IX smooth, subtrapezoidal. Laterotergites IX slightly surpassing sclerite uniting laterotergites VIII.

Differential diagnosis: Edessa bivenulata sp. n. is almost identical to E. bituberculata sp. n. (see differential diagnosis on E. bituberculata sp. n.). The species E. bivenulata sp. n. may be readily distinguished from E. bituberculata sp. n. by the presence of a black stripe on the basal outer lateral margin of the corium ( Fig. 8 B View FIGURE 8 ) (not present in E. bituberculata sp. n. — Fig. 8 A View FIGURE 8 ).

Distribution ( Fig. 10 B View FIGURE 10 ): COSTA RICA: Puntarenas; PANAMA: Chiriquí.
