Material studied. Holotype female, BRAZIL, Santa Catarina State, Nova Teutônia [Seara], v.1952. (F. Plaumann) (USNM).

Paratypes. BRAZIL, Rio Grande do Sul State, Viamão, 1 female on Leandra australis flowers, 21.xi.2003, Porto Alegre, 1 female on Borreria verticilata flowers, 11.ii.2011, 2 females on Fabaceae, 11.ii.2011 (F.S.Melo) (UFRGS) ; Piauí State, Bom Jesus, 1 female on soybeans Glycine max, 12.xi.2012 (E.F.B.Lima) (UFPI) .

Comments. N. ikelus is very similar to N. flavens, but can be distinguished using the characters in the key above. Part of the type material used for this description was collected by Fritz Plaumann from 1949 to 1952 (in USNM), but other specimens were also recently collected in southern and northeastern Brazil. The species seems to be widespread in Brazil.
