(Figs. 3–4, 16–22)
Diagnosis (♂). Tegulae with a yellow macula, near the outter margin and medio-distal portion of the outter margin with white scales. Discal region of hindwing with veins lined with brown scales, more evident on the trunk of CuA. Aedeagus with lobe of vesica near to the ejaculatory duct with micro spicules.
Description (♂). Head. Frons light brown, vertex with white scales. Labial palp brown. Thorax. Predominantly light brown. Prothoracic collar with two white maculae; prothoracic coxa white. Tegulae with a yellow basal macula, near the outer margin; medial-distal portion of the outer margin with white scales. Forewing light brown, three region with yellowish semihyaline maculae: (i) triangular on the basal region, between the trunk of R vein and 1A+2A, (ii) rounded, on the median region, between the trunk of R vein and the tornus, (iii) on the subapical region, oblique, between R4 and CuA1; brown band, faded, since the trunk of R vein, on the middle of discal cell, reaching the inner margin; brown macula on the region of closure of discal cell; white maculae on the wing base, on the trunk of R vein; ventral surface with the same dorsal pattern and with a yellow macula on the basal region of costal margin. Hindwing with the costal and outer margins brown, discal region semihyaline and veins lined with brown scales, more evident on the trunk of CuA; region of closure of discal cell lined with brown scales; ventral surface with the same dorsal pattern, but with a yellow macula on the base of costal margin. Abdomen. Dorsally brown with two yellow bands from A2 to A7; ventrally yellow with a central brown stripe. Tuffs of yellow scales at the terminal portion of the abdomen. Genitalia (Figs. 16–22). Tegumen trapezoidal in dorsal view, with the anterior margin straight, and acute posterolateral projections. Uncus bifid, not fused to the tegumen; arms of uncus fused in the anterior portion, not ventrally projected. Valva elliptical; costa with medial apodeme (lacinia), distal apodeme oblique, extended by the inner surface of valva to its middle portion; sacculus developed, consisting of a fold on the inner surface of the valva, oriented towards distal-medial axis; harpe subtriangular; cucullus digitiform; valvula spatulate. Transtilla sclerotized not articulated with the valva and not fused to the juxta. Juxta sclerotized, as an inverted “U”. Saccus without anterior projections. Subscaphium smooth. Aedeagus rectilinear and smooth; ejaculatory bulb rounded, foramen lateral; vesica bilobated, apex of the lobe opposite to the opening of ejaculatory duct sclerotized, lobe near to the ejaculatory duct with microspicules, everted portion of the ejaculatory duct smooth. Female. Unknown.
Etymology. The specific epithet is granted in honor to Wayner Souza Tapajós Lyra, friend who helped senior author during his Ph.D. project, when the species was discovered.
Distribution. The records suggest an endemic distribution in montane mixed ompbrophylous forest of medium and high altitudes in the States of São Paulo and Rio de Janeiro.
Remarks. Although this species is morphologically distinct for the wing pattern, the morphology of the genitalia of D. wayneri resembles that of D. neda (Klug, 1836), differing by not having the uncus fused to the tegumen and by the distinct morphology of the cucullus and the valvula.
