Type species: Hepialodes follicula Guenée, 1858 , by monotypy.

Taxonomic history. Hepialodes was originally described based on the male figure of Hepialodes follicula .

Diagnosis. Hepialodes is distinguished from the remaining Siculodini by: (i) wings ( Fig. 1 View FIGURES 1–2 ) with an ocher ground color with a dry leaf appearance in various shades of brown; (ii) hindwing with the costal margin biconcave; (iii) fenestra triangular; (iv) saccus oval, (v) valva with anterior portion bilobed; (vi) fultura inferior U-shaped; (vii) aedeagus S-shaped; (viii) vesica with cornuti; (ix) tergum VIII rectangular and (x) signum spanning the entire width of the bursa.

Redescription. Forewing: length—males 40.5 mm (n=10), females 39.6 mm (n = 17); apex and distal third of the inner margin concave; divided by dark brown lines on both sides from just over half of the costal margin to the middle of the inner margin, markings less intense on the ventral face, basal area slightly lighter; single tiny white area on the ventral face between R 4 –M 3 at the interception with the mesal line; retinaculum absent.

Hindwing: length—males 34.2 mm (n = 10), females 32.2 mm (n = 17); distal half of the costal margin biconcave; dorsal face with a diffuse line, as a continuation of that of the forewing, to the center of the outer margin, with a second similar line sub-basal from the costal margin to the inner margin; on the ventral face the basal half lighter and lines poorly defined; white spot on both sides, over sub-basal line between M 1 –M 3; frenulum absent.

Male genitalia ( Fig. 5 View FIGURE 5 ): tegumen rectangular in dorsal view, with rounded apex, lateral margins slightly concave, forming lateral lobes; fenestra triangular; saccus oval in lateral view; uncus proximally enlarged, narrowing in the second third and ending in a slightly curved, ventral point, with thin short setae at the beginning of the tapered section; gnathos thin, projected ventrally in a U-shape; valva with developed costa and sacculus, anterior portion bilobed, costa slightly concave, ventral margin sinuous, apex rounded and internal face with scattered setae; fultura inferior U-shaped, with oval ends and short setae; aedeagus cylindrical and S-shaped with rounded opening for the ejaculatory ductus and vesica with a row of approximately 50 thin cornuti.

Female genitalia ( Fig. 9 View FIGURES 9–12 ): tergum VIII rectangular in lateral view, lamella antevaginalis slightly sclerotized, ostium membranous; anterior apophyses as long as the posterior apophyses; bursa copulatrix with slightly sclerotized ductus in the first third, ductus six and a half times longer than the corpus bursae; signum ( Fig. 13 View FIGURES 13–14 ) spanning the entire width of the bursa with numerous sclerotized spines, more abundant and smaller in the central region; papillae anales oval, longer than tall and covered with short and thin setae.
