Diagnosis. Readily distinguished from congeneric species, described below, by (i) the contrasting mottled forewing ornamentation ( Figs 8–12), (ii) ♂triangular sternite VIII ( Fig. 45), (iii) greatly expanded dorso-posterior plate of tergal lobe and pseudotegumen ( Fig. 49), (iv) deeply concave fultura superior ( Fig. 49c), (v) subtriangular valva and (vi) shorter corpus bursae that is only twice as long as the ductus bursae ( Fig. 56).
Description. Male( Figs 11–12, 16, 24, 27, 30, 41, 45, 49). Head. Antenna with ~38 antennomeres. Mesal and distal labial palpomere two and a half times longer than distal palpomere, respectively. Thorax. Forewing length: 15–18 mm, wingspan: 28–35 mm. Wing ornamentation as shown in Figs 11–12. Genitalia( Fig. 49). Tegumen oblique, rectangular, slightly curved, well distinguished from pseudotegumen by its stronger sclerotisation. Saccus U-shaped, posterior arms strongly sclerotised, anterior projection forming bag-like cavity. Tergal lobes and dorsal pseudotegumen fused and forming robust subtriangular wall, dorso-posteriorly projecting on each side, expanded and connected mesally by thicker membrane, antero-ventrally bifid; ridge emerges from digitiform antero-dorsal projection finely fused, posteriorly expanded as lateral shelf on each side. Fultura inferior trapezoidal. Fultura superior subtriangular and deeply concave (in ventral view). Valva subtriangular, lobated and curved distally with expanded costa. Female( Figs 8–10, 28, 34, 38, 54, 56). Head. Antenna with 40 antennomeres. Mesal and distal palpomere five times the length of the basal palpomere. Thorax. Forewing length: 19–22 mm, wingspan: 38–45 mm. Wing ornamentation as shown in Figs 8–10. Genitalia( Figs 54, 56). Dorsal plates narrow, slightly projected posteriorly. Lamella antevaginalis U-shaped, narrow, mesally setose, bilobed and slightly projecting posteriorly (narrowed in Fig. 54a). Subanal sclerites slightly sclerotised, subrectangular, oblique. Corpus bursae narrowing to junction with ductus bursae that is twice as long as the corpus bursae. Geographical distribution. Known from southeastern Minas Gerais and Rio de Janeiroto northeastern Santa Catarina, at altitudes ranging from 700 to 1900 m( Figs 58, 60).
Host plants. Unknown.
Etymology. The proposed specific name dilatus(Latin)alludes to the species’ broad geographic range. It is treated as an adjective in the nominative singular.
