Edessa schirmeri Breddin 1904: 136; Gaedike, 1971: 99; Kirkaldy, 1909: 164.
Edessa schirmeri. Lectotype female. VENEZUELA, Amazonas: Esmeralda, Edessa schirmeri n. spec., Syntypus, Paratypus, Dtsch. Entomol. Institut Berlin, coll. Breddin, DEI Hemimetabola #100295 (SDEI). Examined by photos (Fig. 19 D).
Diagnosis. Dorsal surface of the body olive green (Fig. 19 A). Ventral surface brown with transversal black lines on thorax and abdomen (Fig. 19 B). Antennae brown (Fig. 19 A). Pronotum with punctures brown (Fig. 19 A). Humeral angles short (1,2 times wider than long) (Fig. 19 A), apices black (Fig. 19 A); humeral angle spot restricted to the angle in dorsal and ventral views (Fig. 19 A,B). Scutellum with punctures brown (Fig. 19 A); apex not reach the end of corium (Fig. 19 A). Corium with all veins concolorous with surface (Fig. 19 A). Posterolateral angles of connexivum with apices black (Fig. 19 A); connexival segments with concavities slightly covered by small elliptical black spots separated by a yellow median spot (Fig. 19 A); spots not extending ventrally (Fig. 19 B). Ventral surface. Thorax with black stripes (Fig. 19 B); dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 19 B). Proepisternum with dark stripe (Fig. 19 B). Evaporatorium concolorous with thorax (Fig. 19 B). Metasternal process (Fig. 19 B) with anterior apex straight and laterally well expanded, margin acuminated; anterior face somewhat excavated; anterior bifurcation receiving fourth rostral segment. Legs brown (Fig. 19 B). Abdomen with spine of third segment acuminated (Fig. 19 B). Intersegmental areas black, not reaching lateral margin (Fig. 19 B). Pseudosutures solid black, wide, margin well-defined (Fig. 19 B). Median longitudinal brown band incomplete (Fig. 19 B). Trichobotria parallel to the spiracle. Posterolateral angles of segment VII not reaching level of the apices of laterotergites IX in females (Fig. 19 C). Female genitalia, laterotergites VIII with dark band on outer lateral margins (Fig. 19 C).
Male genitalia: Unknown.
Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous and brown; distal margin brown and sinuous. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 19 C).
Comments. This species resembles Edessa (E.) electa and E. (E.) nigroangulata but can be separated from them by the more curved backward humeral angle (Figs. 19 A, 25 C, 28 E), spots on the connexival segments small and elliptical (Fig. 19 A), and laterotergites VIII without spots (Fig. 19 C). The specimen was examined by photos. The photos were taken by Arne K̂ler (SDEI).
Distribution (Fig. 30 A): VENEZUELA: Amazonas.
