description: Edessa (E.) subandina Breddin, 1904
(Figs. 22, 32 A,B)
Edessa suturata var. (b) subandina Breddin 1904: 135–136; Kirkaldy, 1909: 165.
Edessa subandina. Lectotype female. Esmeralda, Venez [Venezuela]/ Bison Er. / Edessa Suturata Dall / DEI Hemimetabola #100292 (SDEI). Examined by photos. (Fig. 22 D)
Diagnosis. Dorsal surface of the body olive green (Fig. 22 A). Ventral surface brown with transversal black lines on thorax and abdomen (Fig. 22 B). Antennae brown (Fig. 22 A). Pronotum with punctures brown (Fig. 22 A); anterolateral margin and cicatrices with brown punctures (Fig. 22 A). Humeral angles short (1,3 times wider than long) (Fig. 22 A), apices brown (Fig. 22 A); humeral angle brown spot expanding into the pronotum in dorsal view and restricted to the angle in ventral view (Fig. 22 A,B). Scutellum with punctures brown (Fig. 22 A); apex not reach end of corium (Fig. 22 A). Corium with all veins concolorous with surface (Fig. 22 A). Posterolateral angles of connexivum with apices black (Fig. 22 A); connexival segments with concavities almost entirely covered by subrectangular black spots and separated by a large yellow median spot (Fig. 22 A); spots extending ventrally, subrectangular (Fig. 22 B). Ventral surface. Thorax with black stripes (Fig. 22 B); dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 22 B). Evaporatorium concolorous with thorax (Fig. 22 B). Metasternal process (Fig. 22 B) with anterior apex straight and laterally little expanded, margin acuminated; anterior face somewhat excavated; anterior bifurcation receiving fourth rostral segment. Legs brown (Fig. 22 B). Abdomen with spine of third segment acuminated (Fig. 22 B). Intersegmental areas solid black reaching ventral spots of connexivum (Fig. 22 B). Pseudosutures solid black, continuous, solid and regular border (Fig. 22 B). Median longitudinal black band incomplete (Fig. 22 B). Trichobotria parallel to the spiracle. Posterolateral angles of segment VII not reaching level of the apices of laterotergites IX in females (Fig. 22 C). Female genitalia, valvifers VIII with a brown band near the tumescence (Fig. 22 C). Laterotergites VIII with two dark spots on outer lateral margins (Fig. 22 C).
Male genitalia: Unknown.
Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous and not divergent; distal margin brown and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 22 C).
Comments. Edessa (E.) subandina is similar to E. (E.) electa, E. (E.) nigricornis and E. (E.) nigroangulata because of the shape and size of the humeral angle (Figs. 22 A, 25 C, 28 C). However, E. (E.) subandina can be easily separated from the others by the large spots on connexival segments (Fig. 22 A), complete black stripes on ventral side of abdomen (Fig. 22 B), and a small stripe on valvifers VIII close to distal margin (Fig. 22 C). The specimen was examined by photos of the lectotype female. The photos were taken by Stephan Blank (SDEI).
Distribution (Fig. 32 A,B): VENEZUELA: Amazonas.
