Treatment

Edessa congrua . Holotype female. [Amazon region] Braz 62 57/49 [Bates Collection] ( BMNH). Examined.

Material examined. BRAZIL, Pará: 1♁ 1♀, Óbidos, Baixo Amazonas, Dirings ( MZUSP) ; 1♁ 1♀, Santarém, VII ( Compared with type — Fernandes JAM, 1999) ( CMNH) ; Mato Grosso: 2♀, Fazenda Tanguro, Querência , 27-V-2006, F. Fernandes ( UFPA) .

Measurements (n= 6). Total length: 15.3–17.2; head length: 1.4–1.6; head width: 2.7–2.9; pronotum length: 3.2–3.7; pronotum width: 11.0–12.4; scutellum length: 7.0–7.7; scutellum width: 5.5–6.1; abdominal width: 8.4– 9.2; length antennomers: I: 1.0–1.0; II: 1.0–1.4; III: 1.5–1.6; IV: 3.0; V: 3.3.

Diagnosis. Specimens large (15.3–17.2 mm). Dorsal surface of the body green ( Fig. 24 E View FIGURE 24 ). Ventral surface dark yellow to brown with transversal black lines on thorax and abdomen ( Fig. 24 F View FIGURE 24 ). Antennae reddish brown ( Fig. 24 E View FIGURE 24 ). Pronotum with punctures brown or concolorous with surface ( Fig. 24 E View FIGURE 24 ); anterolateral margin and cicatrices with brown punctures ( Fig. 24 E View FIGURE 24 ). Humeral angles short (1,25 times wider than long) ( Fig. 24 E View FIGURE 24 ), apices concolorous with surface and not recurved ( Fig. 24 E View FIGURE 24 ). Scutellum with punctures brown or concolorous with surface ( Fig. 24 E View FIGURE 24 ); apex not reaching end of corium ( Fig. 24 E View FIGURE 24 ). Corium with all veins concolorous with surface ( Fig. 24 E View FIGURE 24 ). Posterolateral angles of connexivum with apices black ( Fig. 24 E View FIGURE 24 ); connexival segments with concavities partially covered by circular black spots and separated by large yellow median spot ( Fig. 24 E View FIGURE 24 ), dark spots extending ventrally, rounded ( Fig. 24 F View FIGURE 24 ). Ventral surface. Thorax with black stripes ( Fig. 24 F View FIGURE 24 ); dark stripe of the propleuron covering 2/3 of the width of the sclerite ( Fig. 24 F View FIGURE 24 ). Evaporatorium concolorous with thorax ( Fig. 24 F View FIGURE 24 ). Metasternal process ( Fig. 3 G View FIGURE 3 ) with anterior apex straight and laterally well expanded, margin acuminated; anterior face broadly excavated; anterior bifurcation receiving fourth rostral segment. Legs with tibiae and tarsi darker than the rest ( Fig. 24 F View FIGURE 24 ). Abdomen with spine of third segment acuminated ( Fig. 3 G View FIGURE 3 ). Intersegmental areas black, not reaching ventral spots of connexivum ( Fig. 24 F View FIGURE 24 ). Pseudosutures partially covered by superficial black stripe ( Fig. 24 F View FIGURE 24 ). Median longitudinal black band incomplete ( Fig. 24 F View FIGURE 24 ). Trichobotria one in line with spiracle and the other laterad. Posterolateral angles of segment VII not reaching level of apices of laterotergites IX in females ( Fig. 3 F View FIGURE 3 ). Male genitalia, posterolateral angle of pygophore slightly developed ( Fig. 3 A View FIGURE 3 ). Superior process of genital cup laminar, rectangular, thick; flattened and coarse in caudal view, continuing ventrally in a crenulated high carina without a distal projection ( Fig. 3 A,B,E View FIGURE 3 ). Ventral rim setose with medial tuft ( Fig. 3 C,D View FIGURE 3 ). Female genitalia, valvifers VIII with distal margin sinuous ( Fig. 3 F View FIGURE 3 ). Laterotergites VIII with two small dark spots on outer lateral margins ( Fig. 3 F View FIGURE 3 ).

Male genitalia ( Fig. 3 A–E View FIGURE 3 ): Parameres with brown margin, anterior lobe small and rounded; dorsal lobe rounded and subrectangular, curved at apex; posterior lobe narrow and rounded ( Fig. 3 D,E View FIGURE 3 ). Proctiger with subpentagonal posterior face ( Fig. 3 D,E View FIGURE 3 ). Ventral rim with expansions little developed, rounded, concolorous with surface, the expansions not reaching beyond apices of posterolateral angles ( Fig. 3 B,C View FIGURE 3 ).

Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous, with brown band and divergent; distal margin brown and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII ( Fig. 3 F View FIGURE 3 ).

Comments. The male of E. (E.) congrua is described here for the first time. See comments of E. (E.) alces .
