(Figs.13–18; 44; 51; 56)
Edessa picticornis Stål 1872:58; Distant 1880: 95; Lethierry and Severin 1893: 193; Kirkaldy, 1909: 162.
Lectotype male: Mexico, Oaxaca (BMNH). Here designated.
Paralectotype female with the same data (BMNH).
Material. MEXICO, ♂ ♀ Sallé, Distant Coll. 1911-383, Edessa picticornis, Stål 1872. Comp. W. Type. Fernandes, JAM 1999 (BMNH). Oaxaca: ♀ 2 miles north, San Jose del Pacifico, 16-vii-1974, Clark, Murray, Asher, Schaffner (JEE).
Measurements. Head length (2.4–2.5); head width (3.2–3.5); pronotal length (2.3–2.6); pronotal width (6– 6.9); total length (11–12); abdominal width (6–6.5).
Body green with corium brown (Fig. 44), ventrally dark yellow to brown (Fig. 51). Cephalic disc not punctured. Mandibular plates smooth or rugulose; uniformly green or with a few dark punctures and spots; level with clypeus and cephalic disc but with a slight concavity at base. Ventral surface of head dark yellow, dark spotted above and below antenniferous tubercles; sparsely punctured. First three antennal segments light brown and densely spotted, fourth brown, basal third and apex of fifth segment whitish. Pronotum uniformly green, punctures dense and light brown; anterolateral margin yellow. Humeral angles with margins dark. Apex of scutellum with a faded impunctate area. Hemelytron with an oblique faded spot on corium. Ventral punctures of thorax concolorous. Metasternal process and evaporatorium with a few tiny dark punctures and spots. Metasternal process brown, arms of bifurcation lighter, strong and divergent (Fig. 18). Legs densely dark spotted. Connexivum with greenish-brown and yellow spots, punctures dense brown or concolorous. Ventral surface of abdomen with dense dark punctures. Female with a rounded pair of dark spots on segment VII.
Male: Pygophore (Figs. 13–15) dark brown. Superior process of the genital cup concave and subtriangular, posterior corner swollen, dorsal margin almost level with dorsal rim (Figs. 13–14). Paramere uniformly brown, tall, progressively widened, and distally rounded, reaching dorsal rim in posterior view (not reaching in Fig. 14 due to drawing position); basal process small and subtriangular, mesial process triangular and larger than basal one (Fig.14). Proctiger with one keel, posterior face subtriangular strongly emarginate due to deep lateral constrictions (Figs. 14–15). Ventral rim dark brown with concolorous punctures; rounded expansion slightly swollen (Figs. 14– 15).
Female: Gonocoxites 8 convex with sparse and dark punctures; medial margins slightly imbricate, posterior margin of both plates forming a “W”, excavation very large exposing part of gonapophyses 8 (Figs. 16–17). Gonocoxite 9 slightly folded, anterior part pyramidal and mostly covered by gonapophyses 8. Laterotergites 9 with transverse grooves, dark punctures concentrated close to middle line; base concave, separate from gonocoxites 8 leaving a space in between them (Fig. 17); apex rounded and surpassing the band uniting laterotergites 8 (Fig. 16).
Comments. This species shares with Edessa luteomaculata sp. nov. body green dorsally with corium greenish-brown; apex of scutellum without a yellow spot; paramere clavate, broad with distal margin rounded; apex of the laterotergites 9 rounded. With the new species E. nigridorsata, it shares the posterior margin of gonocoxite 8 W-shaped. The syntypical series was examined and is formed by a pair; we here designate as lectotype the male specimen.
Distribution (Fig. 56). Mexico: Oaxaca.
