Measurements. Head length (1.2–1.7); head width (3.5–3.7); pronotal length (2–3); pronotal width (6–7.5) total length (10–11); abdominal width (6.5–7).

Body greenish-brown dorsally ( Fig. 42 ), densely punctured, punctures black surrounded by suffused spots on scutellum and corium; some parts with dark spots instead of punctures. Ventral surface dark brown ( Fig. 49 ). Mandibular plates and tylus at the same level, rugulose. Ventral surface of head brown with a tiny dark spot below antenniferous tubercle; not punctured. First three antennal segments brown and densely spotted; basal third of fourth and fifth segments whitish with tiny dark spots densely distributed. Pronotum uniformly greenish-brown, with a median pale line not punctured; anterolateral margin reddish. Apex of scutellum with a yellow spot. Corium with a dark oblique spot. Metasternal process and evaporatorium spotted. Ventral punctures of thorax black. Metasternal process uniformly brown; arms of bifurcation of the metasternal process strong and subparallel. Legs densely dark spotted. Connexivum greenish-brown with dark punctures and a medial small calloused area yellow. Connexivum of segment VII distally dark due to high concentration of dark punctures. Middle ventral surface of abdomen sometimes with sparse punctures. Female without a rounded pair of dark spots on segment VII.

Male: Pygophore mostly brown ( Figs. 1–3 ). Dorsal rim with fine and concolorous punctures concentrated in the middle region. Superior processes of the genital cup pedunculate, distal part oval and concave, swollen margins not reaching dorsal rim ( Fig. 2 ). Paramere with margins dark, distal part elliptical; ventral process laterally directed and longer than distal one ( Figs. 1–2 ). Proctiger with two keels; posterior margin rounded and impunctate ( Fig. 2 ). Ventral rim with dark brown punctures; rounded expansion not swollen ( Figs. 2–3 ).

Female: Gonocoxites 8 strongly convex with dark punctures, excavation of the mesial margins deep, U-shaped ( Fig. 5–6 ), narrower than gonocoxite 9, rounded distally and leaving visible the smooth gonapophyses 8. Gonocoxite 9 constricted just below punctured part, basal part bent upwards forming a small conical projection. Laterotergites 9 punctured and not grooved, acuminate apices surpassing the band uniting laterotergites 8 ( Fig. 5 ).

Comments. The syntypic series is formed by a pair–both were examined and we here designate the male specimen as lectotype of the species. Distant (1881) considered this species close to E. pudibunda , the former having a more linear and less sinuous body, second antennal segment shorter than third, and punctures much closer and coarser. According to measurements presented here Distant inverted the relationship between second and third antennal segments of the species. Edessa godmani shares with E. punctata the body densely and coarsely punctured, metasternal process punctured, punctures and color pattern of the connexivum and a double keel on the proctiger. Edessa godmani can be separate from E. punctata by fourth antennal segment with a light basal ring, smaller size of the superior process of genital cup, shape of paramere and U-shaped excavation of medial margins of gonocoxites 8. The specimen of CNHM coming from Guatemala has a label stating that it was collected in low vegetation along the secondary forest. That is the only information on habitat possibly used by all species of pudibunda group.

Distribution ( Fig.56 ). Mexico: Morelos. Guatemala: Zacapa, Escuintla, Sacapequetez, Patzun. Costa Rica: Puntarenas. Nicaragua: Matagalpa. El Salvador: Usulután.
