Primary type information: Primary type material: 5 syntype males. Primary type localities: 4 males Brazil: São Paulo, Agudos, i.1953, 6.iii.1953, 26.ii.1954, nos 766, 921, 922 (W.W. Kempf) (invalid restriction of type locality by Kempf, 1972b: 154; no lectotype designated), 1 male: Brazil: Bahia, Canudos, vii.1951 (L. Travassos). Primary type depository: MZSP. Type notes: 1) Baroni Urbani, 1977e: 71, cites 1 male syntype in NHMB. 2) Borgmeier, 1955: 591, attributes the Canudos syntype to vii.1951 (L. Travassos), but Baroni Urbani, 1977e: 71, gives iv.1954 (G. Jonscher); probably the NHMB specimen is not a syntype.
