ABSTRACT
Not much is known about the Central American stink bug fauna of the Edessinae subfamily. A recent survey of Costa Rican species from this subfamily listed 65 species, of which 47 were new additions. More recently, a description of a group of species of Edessa added more three species to the fauna of Costa Rica. This work is part of a series of articles aiming to review Edessinae from Central America. In this article seven new species are described from Panama and Costa Rica: Edessa bituberculata sp. n., E. bivenulata sp. n., E. enargocelida sp. n., E. fuscolimbata sp. n., E. fuscopunctata sp. n., E. helvoalata sp. n. and E. holochlorata sp. n.

The subgenus Edessa, the largest and to date the most confusing taxon of Edessa is diagnosed here, comprising 79 species listed in this work. The subgenus is characterized by the humeral angles conical, somewhat developed, and projected, with apex rounded or somewhat acuminated, but never acute, shyny and impunctate or with a few punctures. The E. sexdens group, composed of 22 species, is proposed here to the subgenus Edessa. This group can be characterized by the anterior arms of the metasternal process with excavated apex; connexival segments with a pair of dark spots; ventral side of the abdomen raised medially; rounded shallow excavation near each spiracle; area between dorsal rim of the pygophore and posterolateral angles grooved; superior process of the genital cup laminar and continued ventrally by a carina, oblique to the parameres; parameres with three lobes; area between dorsal rim of the pygophore and posterolateral angles grooved. The species of the E. sexdens group are distributed in the Neotropical region, from Mexico to Argentina. Descriptions, measurements, and illustrations are provided. An identification key and distributional map are presented. The species Edessa suturata Dallas, 1851 is considered junior synonym of E. alces Erichson, 1848; E. inclyta Walker, 1868, E. fuscidorsata Distant, 1881, and E. gnu Breddin, 1905 are considered junior synonyms of E. electa Walker, 1868; E. olivacea Stål, 1862 and E. ventralis Walker, 1868 are considered junior synonym of E. phoenicopus Dallas, 1851; E. nigromarginata Distant, 1881 is considered junior synonym of E. sexdens Fabricius, 1803; E. subandina Breddin, 1994 is considered a valid species; Edessa dentata (Dallas, 1851) and Edessa excellens (Walker, 1868) are considered junior synonym of E. (E.) urus Erichson, 1848.

The new group of species viridula is proposed to five new species: Edessa viridula sp. n., Edessa exigusternata sp. n., Edessa angusticlada sp. n., Edessa rugulata sp. n. and Edessa eucnema sp. n. based on 58 specimens examined. Descriptions of the group and species are provided. Illustrations of the species along with metasternal process and male and female genitalia are provided; an identification key and distributional map are presented.
