Adults. ( Figure 2J View FIGURE 2 , 10O View FIGURE 10 ) Head: male and female antennae simple filiform; antennal tufts present; third segment of male labial palpus long. Thorax: male prothoracic leg with scent pocket; tarsal claws simple, serrate. Wings: males 41 mm, females 40–43 mm; brown coloration; forewing with accessory cell present; hindwing with Sc-Rs stalked. Forewing pattern consists of a light brown ground with a dark diagonal line from the base to the margin of the wing, giving the wing an overall appearance of light wood. Male terminalia ( Figure 6N View FIGURE 6 ): eighth tergite with midplate defined by ridges; eighth sternite with antecosta W-shaped, parallel ridges extend from antecosta to caudal edge, caudal edge modified. SSO compact and well developed, valvae well-sclerotized but irregular in shape with distinctive widening and narrowing along its length such that the apex is much narrower than the remainder of the valva; costa completely sclerotized. Uncus square shaped with a pair of curved, setose processes; tip rounded, slightly bifid; socii sclerotized and thin, bent arms shaped. Juxta triangular. Aedeagus with callosum present; distiphallus with side process; vesica with two types of deciduous cornuti. Female terminalia: seventh sternite primarily membranous with sclerotized semicircle. Papillae anales flattened with long and short setae; posterior apophyses short. Eighth tergite curved, anterior apophyses short. Eighth sternite plain; ostium bursae wide, lamellae antevaginalis sclerotized. Ductus bursae sclerotized, corpus bursae membranous, dorsum with small, sclerotized hump and signum of spinules.

Diagnosis. The genus can be recognized due to the transversal brown line on the forewing, and the unique sternite which is W-shaped with ridges. The particular shape of the lyre-shaped uncus and the bent arm shape of the socii are only found in Lyricinus .

Comments. Lyricinus means the “harpist” or the “lyrist” since the dorsal appearance of the male uncus resembles a Greek lyre ( Weller, 1989). Recorded hostplants include Microdesmia arborea ( Chrysobalanaceae ) (ACG database). Female genitalia illustrated in Weller (1989).

Distribution. Costa Rica to Brazil.
