Edessa lavata Breddin, 1903: 123 ; Kirkaldy, 1909: 159; Gaedike, 1971: 90.

Edessa lavata . Lectotype male. Bolivia ( SDEI). Designated by Gaedike (1971:90, by use of “Holotypus”). Examined ( Fig. 10 C View FIGURE 10 )

Edessa lavata . Paralectotype. Pieter van Doesburg registered a female syntype (ex coll Schouteden) in Brussels (Personal notes). Not examined by the authors .

Campbell ( INPA) ; Rondônia: 1♀, Fazenda Rancho Grande , 5–17-X-1993, J. E. Eger & L. B. & C. W. O’Brien ( JEE) ; 1♁, Rio Pedro, Cacaulândia , 8–20-XI-1994, J. E. Eger coll. ( JEE) .

Measurements (n= 5). Total length: 20.4–23.6; head length: 1.8–2.3; head width: 3.6–3.7; pronotum length: 3.7–4.1; pronotum width: 12.5–14.1; scutellum length: 9.5–10.9; scutellum width: 7.0–8.0; abdominal width: 12.0– 13.5; length antennomers: I: 1.0–1.0; II: 2.0–2.5; III: 1.5–2.0; IV: 4.5–5.0; V: 5.0.

Diagnosis. Specimens large (20.4–23.6 mm). Dorsal surface of the body olive green ( Fig. 10 A,F View FIGURE 10 ). Ventral surface yellow to orange with transversal black lines on thorax and abdomen ( Fig. 10 B,G View FIGURE 10 ). Antennae reddish brown ( Fig. 10 F,G View FIGURE 10 ). Pronotum with punctures black to brown ( Fig. 10 A,F View FIGURE 10 ); anterolateral margin and cicatrices with brown punctures ( Fig. 10 A,F View FIGURE 10 ). Humeral angles short (1,5 times wider than long) ( Fig. 10 A,F View FIGURE 10 ), apices black ( Fig. 10 F View FIGURE 10 ); humeral angle dark spot restricted to the angle in dorsal and ventral views ( Fig. 10 F,G View FIGURE 10 ) (but concolorous with pronotum in poorly preserved lectotype, Fig. 10 A View FIGURE 10 ). Scutellum with brown punctuation ( Fig. 10 A,F View FIGURE 10 ); apex not reaching end of corium ( Fig. 10 A,F View FIGURE 10 ). Corium with all veins concolorous with surface ( Fig. 10 A,F View FIGURE 10 ). Posterolateral angles of connexivum with apices black ( Fig. 10 A,F View FIGURE 10 ); connexival segments with concavities entirely covered by rectangular black spots and separated by a large median light orange spot ( Fig. 10 A,F View FIGURE 10 ), spots extending ventrally, subtriangular ( Fig. 10 B,G View FIGURE 10 ). Ventral surface. Thorax with brown to black stripes ( Fig. 10 B,G View FIGURE 10 ); dark stripe of the propleuron covering 1/3 of the width of the sclerite ( Fig. 10 G View FIGURE 10 ). Evaporatorium concolorous with thorax ( Fig. 10 B,G View FIGURE 10 ). Metasternal process ( Fig. 11 G View FIGURE 11 ) with anterior apex straight and laterally little expanded, margin acuminated; anterior face slightly excavated; anterior bifurcation receiving fourth rostral segment. Legs brown ( Fig. 10 B,G View FIGURE 10 ). Abdomen with spine of third segment acuminated ( Fig. 11 G View FIGURE 11 ). Intersegmental areas brown to black, reaching ventral spots of connexivum ( Fig. 10 B,G View FIGURE 10 ). Pseudosutures concolorous with surface ( Fig. 10 B,G View FIGURE 10 ). Median longitudinal brown band restricted to last segment ( Fig. 10 B,G View FIGURE 10 ). Trichobotria both in line with spiracles. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX in females ( Figs. 10 G View FIGURE 10 , 11 F View FIGURE 11 ). Male genitalia, posterolateral angle of pygophore very developed ( Fig. 11 A View FIGURE 11 ). Superior process of genital cup laminar, rectangular, thick, posterior face coarse and concave ( Fig. 11 B,E View FIGURE 11 ); process continuing ventrally in a crenulated high carina ( Fig. 11 B,E View FIGURE 11 ). Ventral rim setose with medial tuft ( Fig. 10 D,E View FIGURE 10 ). Female genitalia, laterotergites VIII with one dark spots on outer lateral margins ( Fig. 11 F View FIGURE 11 ).

Male genitalia ( Figs. 10 D,E View FIGURE 10 ; 11 A,E View FIGURE 11 ): Parameres with brown margins, anterior lobe rounded, dorsal lobe subtriangular and laterally folded; posterior lobe subtriangular ( Fig. 10 D,E View FIGURE 10 , 11 D,E View FIGURE 11 ). Proctiger with pentagonal posterior face ( Fig. 10 D,E View FIGURE 10 , 11 D,E View FIGURE 11 ). Ventral rim with expansions slightly developed and concolorous with surface ( Fig. 11 C View FIGURE 11 ). Ventral surface ( Fig. 11 C View FIGURE 11 ) of the pygophore with brown spots.

Female genitalia: Valvifers VIII with dark punctures; inner margins brown and contiguous, divergent distally forming V-shaped excavation; distal margin brown and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII ( Fig. 11 F View FIGURE 11 ).

Comments. Female is described for the first time. This species resembles Edessa urus and E. electa by the large size of the body ( Figs. 10 A,B,F,G View FIGURE 10 , 25 C,D View FIGURE 25 , 29 E,F View FIGURE 29 ), shape of the humeral angle ( Figs. 10 A,B,F,G View FIGURE 10 , 25 C,D View FIGURE 25 , 29 E,F View FIGURE 29 ) and color of the connexivum ( Figs. 10 A,B, F,G View FIGURE 10 , Fig. 25 C,D View FIGURE 25 , 29 E,F View FIGURE 29 ). E. (E.) lavata can be separated from E. (E.) urus by the humeral angle black ( Fig. 10 F View FIGURE 10 ) (concolorous in E. urus — Fig. 29 E View FIGURE 29 ) and more developed ( Figs. 10 F View FIGURE 10 , 29 E View FIGURE 29 ), and pronotal margin more concave ( Figs. 10 F View FIGURE 10 , 29 E View FIGURE 29 ) than in E. (E.) urus . E. (E.) lavata has the pronotal angle more directed backwards than in E. electa ( Figs. 10 F View FIGURE 10 , 25 E View FIGURE 25 ); spots of the connexivum are rectangular ( Fig. 10 A,F View FIGURE 10 ) (triangular in E. (E.) electa — Fig. 25 F View FIGURE 25 ); and anterior arms of metasternal process with apex rounded in E. (E.) lavata ( Fig. 11 G View FIGURE 11 ) (straight in E. (E.) electa — Fig. 5 G View FIGURE 5 ).
