Measurements (n= 14). Total length: 16.3–18.7; head length: 1.5–1.8; head width: 3.4; pronotum length: 3.5– 3.8; pronotum width: 10.5–12.5; scutellum length: 7.8–9.3; scutellum width: 6.0–7.3; abdominal width: 9.5–11.3; length antennomeres: I: 1.0; II: 1.5; III: 1.8–2.3; IV: 3.0–3.8; V: 3.8.

Diagnosis. Large (16.3–18.7 mm). Dorsal body surface green ( Fig. 58 A ). Ventral surface dark yellow with transversal brown bands on thorax and abdomen ( Fig. 58 B ). Antennae yellow ( Fig. 58 A–B ). Pronotum densely punctured, with brown to concolorous with the surrounding surface punctures; anterolateral margin emarginated ( Fig. 58 A ). Humeral angles very short (2.0 times wider than long); apex concolorous with the surrounding surface to slightly darker ( Fig. 58 A ). Scutellum with brown to concolorous with the surrounding surface punctures; posterior margin yellow; apex not reaching the end of coria ( Fig. 58 A ). Coria with all veins yellow ( Fig. 58 A ). Connexival segments without spot and flat ( Fig. 58 A ). Posterolateral angles of connexivum with apices concolorous with the surrounding surface ( Fig. 58 A ). Ventral surface, thorax with brown bands; dark band of the propleura covering 1/3 of the width of the sclerite ( Fig. 58 B ). Evaporatorium dark brown ( Fig. 58 B ). Metasternal process ( Fig. 13 G ) with arms of anterior bifurcation straight and laterally little expanded at apex; anterior bifurcation little excavated receiving fourth rostral segment. Legs brown ( Fig. 58 A–B ). Abdomen with spine of segment III acuminated ( Figs. 13 G ; 58 B ). Intersegmental areas covered by wide smoky brown bands with smudged margins, not reaching lateral margins ( Fig. 58 B ). Pseudosutures smoky brown with irregular margins ( Fig. 58 B ). Median longitudinal brown band incomplete ( Fig. 58 B ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX ( Fig. 13 F ). Male genitalia, dorsal rim of the pygophore with margin straight ( Fig. 13 A–B ). Posterolateral angles of the pygophore developed, slightly projected laterally ( Fig. 13 A ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, not continuing ventrally in a high carina ( Fig. 13 B ). Parameres ( Fig. 13 D–E ) with brown margins; anterior lobe subrectangular; dorsal lobe subrectangular with curved apex; posterior lobe subrectangular. Proctiger, posterior face subtriangular ( Fig. 13 D–E ). Ventral surface, punctures distributed in “V” ( Fig. 13 E ). Ventral rim with long setae but without a lateral tuft ( Fig. 13 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 13 C ). Female genitalia, valvifers VIII with brown punctures; sutural margins contiguous, brown and not divergent; posterior margins in open U-shaped excavation, brown and arched. Laterotergites VIII with light brown band on outer lateral margins. Laterotergites IX with apices rounded at the same level as the mediotergite VIII ( Fig. 13 F ).

Comments. See comments on E. (E.) brevicornis sp. n.. Edessa (E.) flavilinea sp. n. differs from E. (E.) brevicornis sp. n. and E. (E.) gentilitia Distant, 1890 (see Mendonça et al., 2023, Fig. 7 F ) by the shape of the excavation of the posterior margins of the valvifers VIII, in E. (E.) flavilinea sp. n. in open U-shaped excavation, while in E. (E.) brevicornis sp. n. in open V-shaped excavation, and in E. (E.) gentilitia the margins are less arched.
