Edessa pudibunda Stål, 1862

( Figs. 26–31 ; 46; 53; 56)

Edessa pudibunda Stål 1862: 117 ; Stål 1872: 61; Distant, 1881: 20; Lethierry and Severin, 1894: 193; Kirkaldy, 1909: 163.

Holotype: ♂ Guatemala (Sacatepequez), Capetillo, Champion coll. ( BMNH).

Material. MEXICO, Puebla: ♀ Teziutlan, 1650 mts., 15-viii-1974, H. Brailosky ( UNAM); ♂ Xicotepec de Juarez, Carr. Tulancingo-Xicotepec de Juarez, Km 40, 13-vii-1994, E. Barrera and C. Mayorga ( UFRG).

Measurements. Head length (2–2.1); head width (2.8–3.4); pronotal length (2.3–2.5); pronotal width (5.8– 6.9); total length (10–12); and width of the abdomen (6.3–6.5).

Body dorsally brown-greenish ( Fig. 46 ) and ventrally dark yellow to brown with large suffused dark areas ( Fig. 53 ). Cephalic disc with punctures sparse. Mandibular plates rugulose, densely punctured and above level of clypeus. Ventral surface of head brown, dark spotted above and below antenniferous tubercles; not punctured. First three antennal segments light brown and densely spotted, basal third of fourth and fifth segments whitish. Pronotum light brown with sparse dark punctures, anterior half lighter than posterior; anterolateral margin yellow. Apex of scutellum with a yellow spot. Hemelytron with a basal dark spot on embolium. Ventral punctures of thorax black. Metasternal process and evaporatorium without punctures. Metasternal process with a medial dark spot, arms of bifurcation short, small and strongly divergent ( Fig. 29 ). Legs densely dark spotted. Connexivum with yellow and black spots without punctures. Connexivum of segment VII with a distal black spot. Ventral surface of abdomen with few and sparse punctures. Female with a rounded pair of dark spots on segment VII.

Male: Pygophore ( Figs. 26–28 ) mostly black. Superior processes of the genital cup concave, subtriangular with swollen corners and reaching dorsal rim ( Figs. 26–27 ). Paramere with dark margins; distal margin straight; distal process wide and rounded, basal one short and laterally curved ( Fig. 27 ). Proctiger with one keel, posterior face rounded with dark punctures ( Fig. 27 ). Ventral rim brown dark punctured; acuminate expansions slightly swollen ( Fig. 28 ).

Female: Gonocoxites 8 strongly convex with sparse dark punctures, excavation of medial margins large, Ushaped ( Figs. 30–31 ), as broad as gonocoxite 9, forming a spiniform process distally and leaving visible part of gonapophyses 8. Gonocoxite 9 slightly bent just below dark part and medially carinate. Laterotergites 9 grooved transversely, acuminate apex surpassing the band uniting laterotergites 8 ( Fig. 30 ).

Comments. The female is described for the first time here. This species is recognized by the shape of the paramere, the large excavation between medial margins of the gonocoxites 8, the arms of the bifurcation of metasternal process strongly divergent and small compared with other species. The allied species Edessa nigriventris sp. nov. and Edessa nigridorsata sp. nov. share with E. pudibunda fourth and fifth antennal segments with a whitish ring at base, suffused spot on metasternal process, black and yellow color pattern on connexivum, abdomen ventrally mostly black or with large black areas and punctures sparse and concolorous.

Distribution ( Fig. 56 ). Mexico: Puebla. Guatemala: Sacatepequez.
