(Figs. 1–2, 9–15)
Diagnosis (♂). Tegulae with a reddish basal macula near the outer margin. Ventral surface of forewing and hindwing with a red macula on the base of costal margin, discal region of hingwing semihyaline yellowish. Valva with subtriangular harpe and vavula absent.
Description (♂). Head. Frons, vertex and labial palp brown. Thorax. Predominantly brown. Prothoracic collar with two yellow maculae; prothoracic coxa brown. Tegulae with a reddish basal macula, near the outer margin. Forewing brown, three region with whitish semihyaline maculae: (i) on the basal region, between the trunk of R vein and the inner margin, (ii) on the median region, between the trunk of R vein and the inner margin, with the distal margin of the maculae with rounded contour, touching the subapical macula between M3 and CuA1, (iii) on the subapical region, oblique, between the costal margin and e CuA1; dark-brown band, since the trunk of R vein, on the middle of discal cell, reaching the inner margin, faded between the trunk of CuA e CuP; dark brown macula on the region of closure of discal cell; two maculae on the wing base, reddish on the
trunk of R vein and white on the trunk of CuA; ventral surface with the same dorsal pattern. Hindwing with the costal and outer margins brown, discal region yellowish semi hialyne, region of closure of discal cell lined with brown scales; ventral surface with the same dorsal pattern, but with a red macula on the base of costal margin. Abdomen. Dorsally brown with two light brown faded bands on A2 reaching A8; ventrally light brown with two lateral bands formed by yellow maculae on the segments A2-A8. Tuffs of reddish scales at the terminal portion of the abdomen. Genitalia (Figs. 9–15). Tegumen trapezoidal in dorsal view straight anteriorly, with acute posterolateral projections. Uncus bifid, not fused to the tegumen; arms of uncus fused in the anterior portion, not ventrally projected. Valva subelliptical; costa with medial apodeme (lacinia) acute, 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 indistinct. Transtilla sclerotized not articulated with the valva and not fused to the juxta. Juxta sclerotized, shaped like an inverted “U”. Saccus without anterior projections. Subscaphium smooth. Aedeagus straight 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 smooth, everted portion of the ejaculatory duct smooth. Female: Unknown
Etymology. The specific epithet is granted in honor to Rodrigo Urias dos Santos, partner of the senior author to whom he dedicates his love.
Distribution. The few records for this species suggest an endemic distribution to montane dense ombrophilous forest of medium and high altitudes in the States of São Paulo and Rio de Janeiro.
Remarks: This species is known only by males. The wing pattern is similar to D. hilara (Weymer, 1895). However, D. uriasi is distinguished by having whitish color marks on the hindwings, and a red prothoracic collar
