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 ). FIGURE 19. A–D. Edessa ( E. ) schirmeri Breddin, 1904 : A–B, dorsal and ventral surface of the lectotype; C, genital plates; D, lectotype labels. Scale 1 mm for genitalia and 5 mm for dorsal and ventral surfaces. The photos were taken by Arne K̂ler (SDEI). 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 .
