Edessa fuscopunctata sp. n.

( Figs. 5 View FIGURE 5 ; 9 A, D View FIGURE 9 ; 10 A View FIGURE 10 )

Etymology. The name refers to the black color of the pronotal punctuation (L. Fusco - black; punctum - hole).

Material examined. Holotype male. COSTA RICA. Puntarenas: 1♁, Corcovado National Park, Osa Peninsula , 5–11/VIII/1979, D. H. Janzen, INBIO CRI001 702800 ( INBio).

Paratypes. COSTA RICA. Puntarenas: 1♁, Sirena, Corcovado Nat. Pk., Osa Peninsula , 13–22/III/1980, D. H. Janzen & W. Hallwachs, INBIO CRI001 715378 ( INBio) ; 1♁, Corcovado Nat. Pk. Osa Penin, 15–22/III/1979, coll. D. H. Janzen, INBIO CRI001 702253 ( INBio) ; 1♀, Est. Sirena, ACOSA. 1–100m, 5–24/IV/1995, B. Gamboa, L N 270500 507900#4738, INBIO CRI002 188039 ( INBio) .

Measurements (n= 4): antennomeres length: 1st: 0.51–0.67mm; 2nd: 1.02–1.14mm; 3rd: 1.90–2.89mm; 4th: 3.48–3.57mm; 5th: 3.37mm; head length: 1.34–1.49mm; head width: 2.83–2.85mm; pronotal length: 2.79–2.99mm; pronotal width: 6.88–7.27mm; scutellum length: 5.55–5.96mm; scutellum width: 4.15–4.50mm; abdominal width: 6.87–7.23mm; total length: 12.99–13.68mm.

Diagnosis: body dorsally green except variegated brown corium ( Fig. 9 A View FIGURE 9 ). Antennae brown, basal portion of 5th antennomeres whitish ( Fig. 9 A View FIGURE 9 ). Anterolateral margin of pronotum with narrow yellowish stripe ( Fig. 9 A View FIGURE 9 ). Pronotum with punctures black, coarse, covering most of pronotum except on cicatrices, anterior margin and anterolateral margins ( Fig. 9 A View FIGURE 9 ). Black minute longitudinal callosity adjacent to humeral angles ( Fig. 9 A View FIGURE 9 ). Scutellum with transverse diffuse brown stripe on midposterior region ( Fig. 9 A View FIGURE 9 ). Corium with diffuse yellowish and reddish shade, black longitudinal stripe on basal portion of lateral margin ( Fig. 9 A View FIGURE 9 ). Connexival segments with yellowish spots ( Fig. 9 A View FIGURE 9 ). Last connexival segment mostly black ( Fig. 9 A View FIGURE 9 ). Ventral surface: yellowish with thoracic dark lines restricted to propleura and abdominal dark lines narrow and incomplete ( Fig. 9 D View FIGURE 9 ). Anterior bifurcation of the metasternal process with arms narrow, apices acuminated ( Fig. 9 D View FIGURE 9 ). Male genitalia: pygophore subrectangular ( Fig. 5 A, B View FIGURE 5 ). Dorsal rim freely projected over slightly developed posterolateral angles ( Fig. 5 A View FIGURE 5 ). Superior process of the genital cup arrowhead-like, slightly bent, medially excavated ( Fig. 5 C, D View FIGURE 5 ). Parameres with anterior lobe triangular and developed ( Fig. 5 C, D View FIGURE 5 ); dorsal margin deeply excavated ( Fig. 5 C, D View FIGURE 5 ); posterior lobe short, digitiform and straight ( Fig. 5 C, D View FIGURE 5 ). Proctiger slightly excavated laterally ( Fig. 5 C, D View FIGURE 5 ). Ventral rim with median notch subrectangular; expansions developed and triangular ( Fig. 5 B View FIGURE 5 ). Female genitalia ( Fig. 5 E View FIGURE 5 ): valvifers VIII punctured medially; medially largely excavated.

Description: head: clypeus and jugae, slightly ridged. Bucculae subtriangular, harboring first labial segment almost completely. Thorax: dorsal surface: anterior margin of pronotum with subtle intermittent row of punctures ( Fig. 9 A View FIGURE 9 ). Humeral angle with small black stripe at the apex, short, about as long as the width of an eye ( Fig. 9 A View FIGURE 9 ). Scutellum very acute, punctures coarse, grouped much tighter on brown stripe and adjacent areas; distal part unpunctured ( Fig. 9 A View FIGURE 9 ). Membrane transparent, slightly dark ( Fig. 9 A View FIGURE 9 ). Ventral surface: prothorax with black, dense, irregularly distributed punctures ( Fig. 9 D View FIGURE 9 ). Mesothorax with few minute, shallow punctures ( Fig. 9 D View FIGURE 9 ). Peritreme ruga-like, reaching 2/3 of the distance between ostiole of the scent gland and lateral margin of metapleuron ( Fig. 9 D View FIGURE 9 ). Metasternal process with anterior arms slightly divergent, anterior bifurcation receiving only fourth rostral segment ( Fig. 9 D View FIGURE 9 ). Abdomen: dorsal surface: posterolateral angles of connexival segments with distal black spot ( Fig. 9 A View FIGURE 9 ). Male genitalia: dorsal rim light-brown, slightly sinuous, broadly excavated ( Fig. 5 A View FIGURE 5 ). Posterolateral angles slightly developed, gently excavated on inner face ( Fig. 5A View FIGURE 5 ). Ventral rim with expansions short and slightly swollen ( Fig. 5 B View FIGURE 5 ). Female genitalia ( Fig. 5 E View FIGURE 5 ): valvifers VIII slightly convex; distal margin slightly arched; median excavation widely exposing valvulae IX. Laterotergites VIII sharp distally, outer lateral margin almost straight; free distal spinose part about 1/5 of its length. Valvifers IX smooth, trapezoidal. Laterotergites IX acute distally, barely surpassing sclerite uniting laterotergites VIII.

Differential diagnosis: Edessa fuscopunctata sp. n. is more similar to E. fuscolimbata sp. n. (see differential diagnosis of E. fuscolimbata sp. n.). But Edessa fuscopunctata sp. n. can be separated from E. fuscolimbata sp. n. by the brown midposterior stripe on scutellum ( Figs. 9 A View FIGURE 9 ; 8 G View FIGURE 8 ); humeral angles very short ( Figs. 9 A View FIGURE 9 ; 8 G View FIGURE 8 ); pygophore with genital cup process arrowhead-like ( Figs. 5 C, D View FIGURE 5 ; 4 C, D View FIGURE 4 ), and dorsal rim projected freely over humeral angles ( Figs. 5 A View FIGURE 5 ; 4 A View FIGURE 4 ).
