16. EUXOGA MÖSCHLER, 1878 View in CoL
Euxoga Moeschler, 1878 . Verhandl. zool.-bot. Ges Wien 27: 692. Type species: Euxoga argenteopunctata Moeschler, 1878 . ibid: 692.
Adults. ( Figure 2D View FIGURE 2 , 10L View FIGURE 10 ) Head: antennae in males can be bipectinated to basal half or simple filiform, simple filiform in females; antennal tufts present; male and female with third segment of labial palpus long. Thorax: prothoracic scent pocket absent; tarsal claws simple; tibial spurs with ridge or comb. Wings: males 40 to 41 mm, females 42 mm; thin-bodied moths with pastel colored, geometrid-shaped, truncated wings; forewing with accessory cell present; hindwing with Sc-Rs stalked. Male terminalia ( Figure 6H View FIGURE 6 ): eighth sternite and tergite species-specific, in E. argenteopunctata the eighth tergite has a midplate while the sternite has two basal processes. SSO discrete; valvae long and membranous with hairs along distal edge ( E. balba Dognin ) or valvae entirely absent ( E. argenteopunctata ). Uncus tapered with apodemes incomplete or absent; uncus rounded with distal, membranous projection curved dorsally; socii thin, sclerotized rods, upturned tip. Aedeagus thin and simple with callosum present, vesica with large spines. Female terminalia: Papillae anales lightly sclerotized with scattered setae. Eighth tergite caudal margins highly curved; eighth sternite with midventral prominences; ostium bursae wide and m-shaped; ductus bursae long and sclerotized; corpus bursae membranous with weakly sclerotized hump dorsal to ductus bursae; one signum.
Diagnosis. These moths are somewhat similar to geometroids or erebids and have unique genitalia. Those of the type species lack valvae and instead have long setae whereas the genitalia of E. balba have thin, narrow valvae with heavily sclerotized costa. See comments below Goaxis regarding taxonomic uncertainty surrounding these two genera.
Comments. Specimens are rare in collections and might be misplaced with unsorted geometrids, female genitalia illustrated in Weller (1989).
Distribution. From Guatemala to Brazil.
Species included (9).
