Edessa fuscopunctata sp. n.

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

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). Antennae brown, basal portion of 5th antennomeres whitish ( Fig. 9 A). Anterolateral margin of pronotum with narrow yellowish stripe ( Fig. 9 A). Pronotum with punctures black, coarse, covering most of pronotum except on cicatrices, anterior margin and anterolateral margins ( Fig. 9 A). Black minute longitudinal callosity adjacent to humeral angles ( Fig. 9 A). Scutellum with transverse diffuse brown stripe on midposterior region ( Fig. 9 A). Corium with diffuse yellowish and reddish shade, black longitudinal stripe on basal portion of lateral margin ( Fig. 9 A). Connexival segments with yellowish spots ( Fig. 9 A). Last connexival segment mostly black ( Fig. 9 A). Ventral surface: yellowish with thoracic dark lines restricted to propleura and abdominal dark lines narrow and incomplete ( Fig. 9 D). Anterior bifurcation of the metasternal process with arms narrow, apices acuminated ( Fig. 9 D). Male genitalia: pygophore subrectangular ( Fig. 5 A, B). Dorsal rim freely projected over slightly developed posterolateral angles ( Fig. 5 A). Superior process of the genital cup arrowhead-like, slightly bent, medially excavated ( Fig. 5 C, D). Parameres with anterior lobe triangular and developed ( Fig. 5 C, D); dorsal margin deeply excavated ( Fig. 5 C, D); posterior lobe short, digitiform and straight ( Fig. 5 C, D). Proctiger slightly excavated laterally ( Fig. 5 C, D). Ventral rim with median notch subrectangular; expansions developed and triangular ( Fig. 5 B). Female genitalia ( Fig. 5 E): 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). Humeral angle with small black stripe at the apex, short, about as long as the width of an eye ( Fig. 9 A). Scutellum very acute, punctures coarse, grouped much tighter on brown stripe and adjacent areas; distal part unpunctured ( Fig. 9 A). Membrane transparent, slightly dark ( Fig. 9 A). Ventral surface: prothorax with black, dense, irregularly distributed punctures ( Fig. 9 D). Mesothorax with few minute, shallow punctures ( Fig. 9 D). Peritreme ruga-like, reaching 2/3 of the distance between ostiole of the scent gland and lateral margin of metapleuron ( Fig. 9 D). Metasternal process with anterior arms slightly divergent, anterior bifurcation receiving only fourth rostral segment ( Fig. 9 D). Abdomen: dorsal surface: posterolateral angles of connexival segments with distal black spot ( Fig. 9 A). Male genitalia: dorsal rim light-brown, slightly sinuous, broadly excavated ( Fig. 5 A). Posterolateral angles slightly developed, gently excavated on inner face ( Fig. 5A). Ventral rim with expansions short and slightly swollen ( Fig. 5 B). Female genitalia ( Fig. 5 E): 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; 8 G); humeral angles very short ( Figs. 9 A; 8 G); pygophore with genital cup process arrowhead-like ( Figs. 5 C, D; 4 C, D), and dorsal rim projected freely over humeral angles ( Figs. 5 A; 4 A).
