Measurements (n= 9). Total length: 20.4–24.5; head length: 1.6–2.5; head width: 3.7–4.0; pronotum length: 3.7–4.4; pronotum width: 13.9–16.2; scutellum length: 10.1–11.1; scutellum width: 7.5–8.5; abdominal width: 13.0–14.3; length antennomers: I: 1.0–1.0; II: 2.0–2.3; III: 2.5–2.7; IV: 5.0–5.1; V: 6.1–0.0.

Diagnosis. Specimens large (20.4–24.5 mm). Dorsal surface orange ( Fig. 27 E ). Ventral surface dark yellow to orange with transversal black lines on thorax and abdomen ( Fig. 27 F ). Antennae brown ( Fig. 27 E ). Pronotum with punctures concolorous with surface ( Fig. 27 E ); with thick dark band on the posterior margin and may be complete or incomplete ( Fig. 27 E ). Humeral angles short (1,5 times wider than long) ( Fig. 27 E ), apices black ( Fig. 27 E ); humeral angle black spot expanding to pronotum in dorsal and ventral views ( Fig. 27 E,F ). Scutellum with punctures concolorous with surface ( Fig. 27 E ); apex black, not reach end of corium ( Fig. 27 E ). Corium black with all veins concolorous with surface ( Fig. 27 E ). Posterolateral angles of connexivum with apices black ( Fig. 27 E ); connexival segments with concavities entirely covered by rectangular black spots and separated by a large yellow median spot ( Fig. 27 E ), spots extending ventrally and dark spot with joining the intersegmental regions of the abdomen and forming dark bands that occupy two segments ( Fig. 27 F ). Ventral surface. Thorax with black stripes ( Fig. 27 F ); dark stripe of the propleuron connected to the dark spot of the humeral angle ( Fig. 27 F ). Evaporatorium concolorous with thorax ( Fig. 27 F ). Metasternal process ( Fig. 14 G ) with anterior apex straight and laterally little expanded, margin rounded; anterior face somewhat excavated; anterior bifurcation receiving fourth rostral segment. Legs orange ( Fig. 27 F ). Abdomen with spine of third segment acuminated ( Fig. 27 F ). Lateral margin black, expanding on intersegmental areas, except large yellow spots on ventral part of connexivum ( Fig. 27 F ). Median longitudinal brown band restricted to segment VII and part ofVI ( Fig. 27 F ). Small rounded light brown spots near the spiracles ( Fig. 27 F ). Trichobotria one in line with spiracle and the other laterad. Posterolateral angles of segment VII on the same level of apices of laterotergites IX in females ( Fig. 14 F ). Male genitalia, dorsal side of the pygophore with a suffused reddish area occupying 1/3 of the surface ( Fig. 14 A,B,D,E ). Posterolateral angle of pygophore very developed ( Fig. 14 A ). Superior process of genital cup laminar, rectangular, thick; flattened and coarse in posterior view, continuing ventrally in a crenulated high carina, ending in a small dentiform projection ( Fig. 14 B,E ). Ventral rim not setose ( Fig. 14 C ). Female genitalia, valvifers VIII with a small dentiform projection that protrudes into the valvifers IX ( Fig. 14 F ); tumescence in the central region of the valvifers VIII with black spot ( Fig. 14 F ); laterotergites VIII black two black spots on outer lateral margins ( Fig. 14 F ); laterotergites IX with black spot ( Fig. 14 F ).

Male genitalia ( Fig. 14 A–E ): Parameres with black margin; anterior and posterior lobe little developed and rounded; dorsal lobe rounded and subrectangular ( Fig. 14 B,D,E ). Proctiger with subelliptical posterior face ( Fig. 14 D,E ). Ventral rim with expansions little developed, rounded, concolorous with surface, the expansions not reaching beyond apices of posterolateral angles ( Fig. 14 C ).

Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous, with brown band and not divergent; distal margin forming U-shaped excavation, with brown band and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII ( Fig. 14 F ).

Comments. The female of Edessa (E.) miniata is described for the first time. This is a very peculiar species of Edessa due to its dorsal pattern of large black areas contrasting with red parts of the body ( Fig. 27 E ), also contrasting with yellow spots on connexivum ( Fig. 27 E ).
