( Figs. 9 , 31 A )

Edessa imbecilla Breddin, 1903: 123 ; Gaedike, 1971: 88; Kirkaldy, 1909: 159.

Edessa imbecilla . Lectotype male. BOLIVIA, La Paz: Yungas, Edessa imbecilla Bredd , coll. Breddin, Typus, Dtsch. Entomol. Institut Berlin, DEI Hemimetabola #100257 ( SDEI) ( Fig. 9 F ). Examined by photos.

Diagnosis. Dorsal surface green ( Fig. 9 A ). Ventral surface dark yellow to green with transversal dark green lines on thorax and abdomen ( Fig. 9 B ). Antennae first segment light brown and second to fifth black ( Fig. 9 A ). Pronotum with punctures concolorous with surface ( Fig. 9 A ). Humeral angles short (1,3 times wider than long) ( Fig. 9 A ), apices concolorous with surface ( Fig. 9 A ). Scutellum with punctures concolorous with surface ( Fig. 9 A ), apex not reach end of corium ( Fig. 9 A ). Corium with all veins concolorous with surface ( Fig. 9 A ). Posterolateral angles of connexivum with apices green ( Fig. 9 A ); connexival segments with concavities entirely covered by rectangular green spots and separated by a large yellow median spot ( Fig. 9 A ), spots extending ventrally and green spot forming green bands on the abdomen ( Fig. 9 B ). Ventral surface. Thorax with green stripes ( Fig. 9 B ); dark stripe of the propleuron connected to the dark spot of the humeral angle ( Fig. 9 B ). Evaporatorium concolorous with thorax ( Fig. 9 B ). Metasternal process ( Fig. 9 B ) with anterior apex rounded and little expanded laterally, margin rounded; anterior face somewhat excavated; anterior bifurcation receiving fourth rostral segment. Legs brown ( Fig. 9 B ). Abdomen with spine of third segment rounded ( Fig. 9 B ). Intersegmental areas green ( Fig. 9 B ). Pseudosutures concolorous with surface ( Fig. 9 B ). Median longitudinal brown band restricted to the last segment ( Fig. 9 B ). Trichobotria lateral to spiracles. Male genitalia, parameres with dorsal lobe acuminate, curved toward posterolateral angles ( Fig. 9 D,E ). Proctiger with lateral face strongly excavated and posterior face subtriangular ( Fig. 9 D,E ). Expansions of ventral rim swollen and directed ventrally ( Fig. 9 C ). Ventral rim with long setae, but without tuft ( Fig. 9 C ).

Male genitalia ( Fig. 9 C–E ): Parameres with black margin; anterior lobe rounded; posterior lobe subrectangular ( Fig. 9 D,E ). Ventral rim with expansions strongly developed, rounded, concolorous with surface, level with posterolateral angles ( Fig. 9 C ).

Female genitalia: Unknown.

Comments. The Edessa (E.) imbecilla is known only for the type. The lectotype was poorly preserved, but still shows traces of the original green color ( Fig. 9 A,B ). Thus, the color description presented here for E. (E.) imbecilla is based on other similar well-preserved species. The specimen was described based on photos of the lectotype male. This species can be separated from the others described here by the color of the connexivum ( Fig. 9 A ) and by the color of the ventral surface of the abdomen ( Fig. 9 B ). The photos were taken by Arne K̂ler (SDEI).
