Style ( Fig. 86), in dorsal view, with outer lobe rounded; blade abruptly curved laterally posterior to outer lobe; in lateral view, ( Fig. 87), blade with ventral margin serrated; apex strongly rounded with dorsal preapical spiniform process. Aedeagus ( Figs 88, 89), with preatrium underdeveloped; dorsal apodeme developed, dorsal margin slightly rounded, lateral margins not projected laterally; atrium with a pair of elongated processes, each with a long dorsal digitiform lobe at middle portion, almost reaching apex of shaft, and with apex acute, slightly curved anteriorly; shaft elongated, thin, subtubular, mostly straight, and symmetrical, basal portion, in lateral view, curved and rounded, forming an U, apical portion membranous and with a pair long and thin lateral processes about one-third of the length of the shaft, directed ventrally, and with apices acute.  Female terminalia.Female unknown.   Etymology.The species epithet means “shadow” in Latin, referring to the dark color of the face of typespecimens. It is a noun in apposition.   Material examined.   Holotypemale:“ Brazil, RJ, Itatiaia, PNI\  12.II.2015, S 22°25’20.2’’ W\ 44°38’10.0’’,  1642m, Ponto\ 04, Monteiro et al.” ( DZRJ).   Paratypes: Itatiaia: 4♂, “same data as holotype, except: “  27.

However,  Curtara( Curtara) umbra  sp. nov.can be easily distinguished from  C.( Curtara) andresi  sp. nov.by its aedeagus ( Fig. 88) with atrial processes with dorsal margin expanded forming a digitiform process, while in  C.( Curtara) andresi  sp. nov.has the atrial processes with dorsal margin expanded, but not forming process ( Fig. 12).    Curtara( Curtara) umbra  sp. nov.was collected at PNI at altitudes from 1,642 to 2,061 ma.s.l. 4880013426 2015-02-12 DZRJ Brazil 1642 Itatiaia 19 566 1 holotype 4880013320 2014-02-27 2015-01-07 2014-02-27 DZRJ, MNRJ Brazil 1846 -22.416945 Itatiaia 1 -44.642475 Itatiaia 19 566 6 6 paratype 4880013427 2015-01-07 2015-01-07 2014-02-27 DZUP Brazil 2061 -22.402945 Itatiaia 1 -44.642475 Itatiaia 19 566 1 1 paratype
