Measurements. Head length (2.1); head width (3.2–3.7); pronotal length (2.3–2.8); pronotal width (6.5–7.5); total length (11–13); abdominal width (6.5–7).

Body greenish-brown dorsally ( Fig. 43 ) and yellow to dark brown ventrally ( Fig. 50 ); densely punctured, punctures black, sometimes surrounded by suffused spots on scutellum, corium and abdomen; some parts with dark spots instead of punctures. Head uniformly and densely punctured. Mandibular plates gently rugose and level with clypeus and cephalic disc. Ventral surface of head dark yellow and punctured, dark spotted below antenniferous tubercles. First three antennal segments light brown and spotted; fourth and fifth segments brown and not spotted. Pronotum brown with dense dark punctures, anterior half lighter than posterior; anterolateral margin reddish. Apex of scutellum with a large yellow spot. Corium with a dark faded oblique spot. Ventral punctures of thorax black. Metasternal process and evaporatorium with dense dark spots. Metasternal process light brown, arms of bifurcation strong and divergent. Legs densely dark spotted. Connexivum greenish-brown with dark punctures and a medial small calloused area yellow. Ventral surface of abdomen densely punctured. Female without a rounded pair of dark spots on segment VII.

Male: Pygophore ( Figs. 7–9 ) brown. Dorsal rim with a dark spot restricted to middle region. Superior processes of the genital cup slightly concave and elliptical ( Figs. 7–8 ); margin slightly tumid and reaching dorsal rim ( Fig. 8 ). Paramere pale with margins brown; dorsal part elliptical, ventral process long and laterally directed ( Fig. 8 ). Proctiger with two almost inconspicuous keels; posterior face ogive-like ( Fig. 8 ). Ventral rim yellow to brown with tiny dark punctures; expansions rounded and swollen ( Fig. 9 ).

Female: Gonocoxites 8 strongly convex with dense dark punctures ( Fig. 12 ), excavation of medial margins deep, V-shaped ( Fig. 11 ), narrower than gonocoxite 9, rounded distally and leaving visible medially tumid gonapophyses 8. Gonocoxite 9 medially carinate; constricted just below punctate part, basal part turned ventrad forming a small conical projection. Laterotergites 9 punctured and not grooved, acuminate apices surpassing the band uniting laterotergites 8 ( Fig. 11 ).

Comments. The species E. punctata and E. godmani are found at altitudes ranging from 700 to 1,000 meters. They share several characteristics (see comments of E. godmani ), but they can be separate by the shape of the excavation of medial margins of gonocoxites 8 and shape of the paramere. Edessa punctata is more rounded, larger and darker than E. godmani . Both species can be separate from remaining species of the group by the denser and more coarse punctation of the body.

Distribution ( Fig. 56 ). Costa Rica: Puntarenas, Cartago. Panam: Chiriqu.
