Head and thorax ( Figs 14, 15 , 92, 93 ) dull yellow, crown, frons, pronotum and mesonotum with several dark punctures. Crown ( Fig. 14 ) with a small black macula at anterior margin, pair of elongated dark maculae anterior and adjacent to ocelli. Face ( Fig. 15 ) dull yellow; frons with black transverse bands over muscle impressions; antennal pits dark brown; lorum without macula; clypeus with two pairs of dark maculae, one median pair with maculae elongated and second pair with maculae small at apical margin; gena dull yellow with a small black spot adjacent to ventral margin. Proepimeron ( Fig. 16 ) with black stripe below pronotal carina. Mesonotum ( Fig. 14 ) with lateral angles dark brown. Forewing ( Fig. 17 ) dull yellow with several small brown mottled maculae along the entire length of the wing; veins yellow, apex of anal veins and crossveins m-cu1 and m-cu2 dark brown; appendix with a small brown basal and a large brown macula near apex. Legs dull yellow with dark brown and small spots areas; metatibia with cucullate bases of setae dark. Description. Head ( Fig. 14 ), in dorsal view, with crown with median length approximately two-thirds of interocular width, transocular width about nine-tenths of pronotal humeral width; texture with irregular transverse striae, except oblique to longitudinal between ocelli; anterior margin rounded, not projected over anterior margin of the eye; ocelli slightly closer to posterior than anterior margin and closer to midline than to compound eyes. Head ( Fig. 15 ), in ventral view, wider than tall; frons two times longer than wide; frontogenal suture distant from eye margin 2.5 times the diameter of the antennal scape; antennal ledge carinated and oblique, slightly extended over frons; clypeus 1.4 times longer than maximum width, lateral margins straight and parallel. Head ( Fig. 16 ), in lateral view, with transition crown-face defined, thin, and, smooth. Pronotum ( Fig. 14 ), in dorsal view, lateral margins longer than length of eye. Forewing ( Fig. 17 ) with outer discal cell with inner apical accessory vein or veins ( holotype with one longitudinal and one transverse apical accessory veins); m-cu1 crossvein closer to the m-cu2 crossvein than to the R+M fork, m-cu2 anterad to r-m1; appendix slightly narrower than first apical cell. Metatarsomere I pecten with 6 platellae and an external spine. Metatarsomere II with pecten with 3 platellae and a spine on each side. Male terminalia. Sternite VIII ( Fig. 18 ), in ventral view, subtriangular; 1.8 times wider than long; lateral margins converging apically; posterior margin rounded, slightly excavated medially. Valve ( Fig. 19 ), in ventral view, 3.2 times wider than long; slightly sclerotized at middle third; posterior margin deeply excavated medially. Pygofer ( Fig. 20 ), in lateral view, subtriangular; high at base and narrowing towards apex; 1.3 times longer than high; posterodorsal margin slightly excavated, posteroventral margin rounded; macrosetae dispersed medially and apically; apex almost truncated. Anal tube ( Fig. 20 ) membranous. Subgenital plate ( Fig. 20 ), in lateral view, long, almost reaching apex of pygofer; in ventral view, ( Fig. 21 ) elongated and subrectangular, 3.9 times longer than maximum width; outer lateral margin slightly excavated medially; inner lateral margin slightly rounded; apex rounded. Connective ( Fig. 22 ), in dorsal view, transverse; stem absent; dorsal keel absent. Style ( Fig. 22 ), in dorsal view, with outer lobe reduced, subacute; in lateral view ( Fig. 23 ), blade straight; outer face with several sparse setae; ventral margin smooth at basal half and serrated at apical half; apex hook-shaped, strongly curved dorsally. Aedeagus ( Figs 24, 25 ) with preatrium underdeveloped; dorsal apodeme developed, dorsal margin broadly excavated, lateral margins projected laterally; atrium with pair of elongated processes, slightly shorter than shaft, thin at basal half and strongly expanded at apical half, dorsal margin excavated at apical portion, apex acute; shaft elongated, thin, tubular, slightly asymmetrical; basal portion, in lateral view, curved forming an U; apex flattened, expanded laterally with a pair of short spiniform lateral asymmetrical processes, directed dorsally. Female terminalia. Female unknown. Etymology . The new species name comes from the Latin word ‘dilatatus’ meaning dilated. It refers to the expanded apex of the aedeagus ( Fig. 25 ). Material examined. Holotype male: “ Brazil , RJ, Itatiaia , PNI,\ 27.II.2014 , S22º24’10.6’’ W\ 44º38’28.3’’, 2162m , ponto\ 06, Monteiro et al . ( DZRJ )” ; Paratypes : Itatiaia: 2 ♂ , “same data as holotype, except: “ 25.IV.2014 ” ( MNRJ )” ; 2 ♂ “same data as holotype, except: “ 05.XII.2014 ” ( DZUP , MNRJ )” . Taxonomic notes. Curtara ( Curtara ) dilatata sp. nov. resembles the Curtara ( Curtara ) concava DeLong & Freytag, 1976 by its external morphology, color pattern, styles with strongly curved apex ( Fig. 23 ), aedeagus with atrial processes expanded at apical half, and shaft apically expanded with spiniform processes ( Figs 24, 25 ). However, Curtara ( Curtara ) dilatata sp. nov. differs from Curtara concava and other species of the genus by the following set of characteristics: pygofer with apex almost truncated ( Fig. 20 ); style with blade compressed laterally, with ventral margin serrated on apical half ( Fig. 23 ); and aedeagus with apex of shaft with two asymmetrical lateral spiniform processes ( Fig. 24 ). Curtara ( Curtara ) dilatata sp. nov. was collected at PNI only at 2,162 m a.s.l.
