Material studied. BRAZIL, Holotype female, São Paulo State, Franco da Rocha , ( USNMAbout USNM)  ; Santa Catarina State, Nova Teutônia [Seara], 6 females, 3 males from Alchornea  (or Trichilia  ), 14.xii.1949  ; 2 females, 1 male from Trichilia  sp., xii.1949; 1 female, 2 males from Balfourodendron licanum  , 20.xii.1949; 1 female, 1 male from Terminalia  , 26.xi.1949; 1 male from Sapium  , 1.xii.1949; 4 females, 2 males from dry branches, 1.i.1949 (F. Plaumann) (USNM); Rio Grande do Sul State, Jaquirana, 1 female from Myrcia lajeana  , 1 male from Discorea  cf. sublastatum, 1 female from Erythroxylum deciduum  , 28.i.2013, São Francisco de Paula, 1 female from Lamanonia ternata  , 26.i.2013 (A. Cavalleri) ( UFRGSAbout UFRGS). TRINIDAD, St. Joseph , 1 female, ( USNMAbout USNM). 

Comments. Described from 6 females collected near the city of São Paulo, further specimens examined are listed above, including 1 male recorded for the first time. The striae on the anterior area of the pronotum are more widely spaced in the type series than in any of the other specimens listed, but this is here interpreted as intraspecific variation. The wing colour is variable, with the two pale areas, medially and at apex, being poorly defined, as discussed below under N. paraensis  .
