Etymology. The name refers to robust body size (Gr. Echyros, strong).

Measurements (n= 3). Total length: 21.1–23.4; head length: 1.7; head width: 3.5–3.9; pronotum length: 4.6– 5.3; pronotum width: 16.5–17.2; scutellum length: 9.6–10.4; scutellum width: 7.5–8.0; abdominal width: 12.5–13.3; length antennomeres: I: 1.0; II: 2.0–2.2; III: 2.0–2.0; IV: 4.9–5.0; V: 5.3–5.3.

Diagnosis. Large (21.1–23.4 mm). Dorsal body surface brownish olive, densely punctured ( Fig. 57 C ). Ventral surface dark yellow to dark reddish brown with transversal black bands on thorax and abdomen ( Fig. 57 D ), densely punctured. Antennae reddish brown ( Fig. 57 C–D ). Pronotum with brown punctures ( Fig. 57 C ); anterolateral margin and cicatrices with black punctures; anterolateral margin coarse. Humeral angles short (1.25 times wider than long), laterally directed; apex with black spot restricted to the angles in dorsal view, reddish brown in ventral view; abruptly bent backward ( Fig. 57 C–D ). Scutellum with brown punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 57 C ). Coria with all veins slightly lighter than surface ( Fig. 57 C ). Connexival segments with concavities almost entirely covered by subrectangular black spots punctured separated by a large reddish median spot ( Fig. 57 C ); black spots extending ventrally, roundish ( Fig. 57 D ). Posterolateral angles of connexivum with apices black ( Fig. 57 C ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 57 D ). Proepisternum coarse, with dark band ( Fig. 57 D ). Evaporatorium concolorous with the surrounding surface ( Fig. 57 D ). Metasternal process ( Figs. 11 G , 57 D ) with arms of anterior bifurcation straight and laterally well expanded, margin acuminated at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs with femora darker than the other articles ( Fig. 57 D ). Abdomen with spine of segment III rounded ( Figs. 11 G , 57 D ). Intersegmental areas covered by narrow solid black bands with well-defined margins, not reaching the lateral spots ( Fig. 57 D ). Pseudosutures solid black with well-defined margins ( Fig. 57 D ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 57 D ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII at the sam level as the apices of laterotergites IX ( Fig. 11 F ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 11 A–B ). Posterolateral angles of the pygophore developed, projected laterally ( Fig. 11 A,C ). Superior processes of the genital cup subrectangular, thick, in flattened and coarse posterior view ( Fig. 11 B ), continuing ventrally in a crenulate, long and high carina ( Fig. 11 D–E , crenulate carina not visible). Parameres with brown margins; anterior lobe inconspicuous and rounded; dorsal lobe acuminated and curved laterally; posterior lobe subrectangular, with curved apex. Proctiger, posterior face triangular ( Fig. 11 D–E ). Ventral surface with a suffused brown area occupying 1/2 of the surface; densely punctuated; presence of dark spots laterally and medially ( Fig. 11 C ). Ventral rim setose, with medial tuft ( Fig. 11A–C ); with expansions undeveloped and brown with surface ( Fig. 11 C ). Female genitalia, densely punctured. Valvifers VIII with dark punctures; sutural margins brown, contiguous, and not divergent; posterior margin brown and subrectangular; with brown spot in tumescence. Laterotergites VIII with dark band on outer lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 11 F ).

Comments. Edessa (E.) echyra sp. n. resembles E. (E.) glomerosa sp. n. by the robust and brownish olive body; humeral angles black, curved, projected and globose; coria with veins lighter than surface; body ventrally with intersegmental areas black; dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface and ventral rim setose, with medial tuft. On the other hand, both species can be easily separated by the black spot on humeral angles restricted to the dorsal surface of the pronotum (in E. (E.) glomerosa sp. n. black spot slightly expanded); ventral surface of the humeral angles reddish brown (in E. (E.) glomerosa sp. n. black); proepisternum with dark band ( E. (E.) glomerosa sp. n. without this band); ventrally intersegmental areas black bands not reaching the lateral spots ( E. (E.) glomerosa sp. n. black bands reaching the lateral spots); ventral surface densely punctured ( E. (E.) glomerosa lightly punctuated); and the female valvifers VIII with brown spot in tumescence ( E. (E.) glomerosa sp. n. without spot).
