Female (#2313 CM/ MNRJ ), 15.iii.2012 , Queiroz G.C. leg. Deposited at MNRJ in Brazil . One male (#2212 CM/ MNRJ ), 10.xi.2011 , Queiroz G.C. leg. Deposited at MNHN in Paris, France . Locality. Parque Nacional da Serra dos Órgãos (ICMBio), Teresópolis municipality, Rio de Janeiro State, Brazil . 2100 m a.s.l. Local coordinates: 22º27'38"S , 43º1'45"W . Leaf litter and soil of "campos de altitude". Remarks. Labium with 2 x-papillae visible ( Fig. 30 ). Head with Af composed of 7–8 tubercles separated from Oc and CL. Leg chaetotaxy of legs I–III as follows: Scx2– 0, 2, 2; Cx– 3, 7, 8; Tr– 6, 6, 6; Fe– 13, 12, 11; Tita– 18, 18, 17. Furcal rest with 4 chaetae, devoid of mi; Ve chaetae, on ventral anal valves, 13 ( Fig. 32 ). For other differences see Table 6 . Discussion. The specimens of the three localities where Itanura brasiliensis comb. nov. was found are extremely similar, yet differences on important details of chaetotaxy and tubercle development are noteworthy ( Table 6 ). In this way, they recall the pattern of closely related subspecies within Deutonura deficiens ( Deharveng, 1984 ) , suggesting that sampling intermediate locations in this Brazilian region may disclose a complex of parapatric forms (with narrow hybrid or overlapping zones), leading to upgrade these three populations to either subspecies or species level.
