(Figs.19–25; 45; 52; 56)

Etymology. Name refers to yellow spot present in the connexivum.

Holotype ♂. MEXICO, Michoacán: 11mi E Zitacuaro, hwy 15, 9000’, 16-VIII-1982, C.W. and L. O’Brien and G. Wibmer (USNM).

Paratypes. MEXICO, Michoacán: ♀ same data as holotype (DAR); ♀ 24 mi W Ciudad Hidalgo, 25-VII- 1983, Kovarik, Harrison, Schaffner (JEE).

Measurements. Head length (1–1.4); head width (1.9–2); pronotal length (2–2.5); pronotal width (5.9–6.5); total length (9.5–12); abdominal width (5.6–6.6).

Body green with corium greenish-brown (Fig. 45), ventrally dark yellow (Fig. 52). Cephalic disc with a few punctures. Mandibular plates rugulose; uniformly green with dark punctures; level with clypeus and cephalic disc. Ventral surface of head dark yellow, without spots above or below antenniferous tubercles; impunctate. First three antennal segments light brown and densely spotted, fourth and fifth brown with distal half dark. Pronotum green with dense dark punctures, anterior half lighter than posterior; margin yellowish. Apex of scutellum with a small faded not punctured area. Hemelytron with an oblique faded spot on corium. Ventral punctures of thorax concolorous or light brown. Metasternal process and evaporatorium not punctured or spotted. Metasternal process yellow, arms of bifurcation long, strong and divergent (Fig. 25). Legs with small dark spots. Connexivum uniformly greenish or bearing suffused spots, punctures dense brown or concolorous. Female with a pair of dark spots on segment VII. Ventral surface of abdomen with sparse and brown punctures. Female with a rounded pair of dark spots on segment VII.

Male: Pygophore (Figs. 19–21) dark brown. Superior process of the genital cup concave and subtriangular with a posterior protuberance (Figs. 19–20), dorsal margin below the level of dorsal rim. Parameres with margins brown; progressively widened and distally rounded; short and level with proctiger in posterior view (Fig. 20); basal process small and subtriangular, mesial process triangular and larger than basal one, both laterally curved (Fig. 20). Proctiger with one keel, posterior face subtriangular; lateral constrictions broad (Figs. 20–21). Ventral rim dark yellow with fine and light brown punctures; rounded expansion developed and slightly swollen (Figs. 20–21).

Female: Gonocoxite 8 slightly convex (Fig. 22–23) with sparse and dark punctures; short, level with base of gonocoxite 9 (Fig. 23); medial margins rounded, excavation V-shaped exposing a smooth part of gonapophyses 8 (Fig. 22–23). Gonocoxite 9 slightly folded, anterior part pyramidal and completely exposed (Fig. 22). Laterotergites 9 not grooved, bearing dense and dark punctures; base excavated; apex rounded and surpassing the band uniting laterotergites 8 (Fig. 22).

Comments. This species is allied to E. picticornis (see E. picticornis comments for shared characteristics). Edessa luteomaculata can be separated from E. picticornis by the metasternal process not punctured or spotted; abdomen less densely punctured; and by the shape of parameres and gonocoxites 8.

Distribution (Fig. 56). Mexico: Michoacán.
