Phedosia Möschler, 1878 . Type species: Phedosia turbida Möschler, 1878 . ibid.27: 691.

Adults. ( Figure 3H View FIGURE 3 ) Head: male and female antennae filiform; third segment of male labial palpi very short, that of female longer; antennal tufts present and very long. Thorax: male prothoracic leg with single scent pocket. Wings: males 39 mm, females 50 cm; coloration sometimes sexually dimorphic; forewing with accessory cell present, hindwing with Sc-Rs stalked. Abdomen: male second tergite with enlarged pleural area and associated hairlike androconia on caudal edge; third sternite with peniculus on caudal edges. Male terminalia ( Figure 7F View FIGURE 7 ): eighth tergite with midplate; eighth sternite with antecosta weakly to strongly M-shaped, lateral areas with species-specific elaborations. SSO compact and well developed; valvae thin and large; costa a sclerotized rod with enlarged, paddle-like, distal tip. Uncus either slightly or greatly bifid with tip membranous, long setae below; socii sclerotized, fang-like shape or species specific. Costulae absent; juxta triangular. Aedeagus callosum foot-like; distiphallus slender, curved ventrally in P. turbida ; vesica membranous with a small smooth sclerotized patch, projecting ventrally in P. turbida . Female terminalia: Papillae anales membranous with long and short setae; posterior apophyses long and slender; eighth tergite broad; anterior apophyses slender, variable length; eighth sternite caudal edge rounded with a central doublet of small prominences; ostium bursae wide or narrow; ductus bursae sclerotized and dorso-ventrally flattened; narrow and long or wide and short; corpus bursae with sclerotized areas giving rise to internal ridges with saw-toothed edges.

Diagnosis. The antennal tufts of these species are remarkably long. The male valvae have a unique costa with a paddle-like distal tip. Females have saw-toothed ridges within their corpus bursae ( Weller, 1989). Females have a longer third labial palpus segment than those of males.

Comments. Phedosia means brown or dusky and refers to the wing coloration ( Weller 1989). Female genitalia illustrated in Weller (1989).

Distribution. From Costa Rica to Brazil.
