     Lectotype ♂, designated by W.E. LaBerge, in Webb (1980: 110). USA, Illinois, Carlinville, 17 April 1888, by C.A. Robertson [INHS, Robertson no. 7346].

Nomada simplex Robertson, 1902: 80 [♂; the ♀ mentioned as Nomada bella Robertson (not Cresson) but not described]. Synonymy by Mitchell (1962: 413).

     Lectotype ♀, designated by W.E. LaBerge, in Webb (1980: 110). USA, Illinois, Carlinville, 10 April 1896, by C.A. Robertson [INHS, Robertson no. 17800].

Taxonomic notes: Nomada denticulata Robertson, 1902 was originally described from material that Robertson (1895: 124; 1898: 514) originally had misidentified as N. articulata Smith, 1854; from material mentioned in the initial work (Robertson 1895), W.E. LaBerge selected a ♂ lectotype. Similarly, Robertson (1902: 80) indicated that his Nomada simplex Robertson had previously been misidentifed as the undescribed ♀ of N. bella Cresson, 1863 by Robertson (1897: 340), so in the latter work (i.e., Robertson 1902) only provided a description of the ♂, with no location information. The lectotype of N. simplex selected by W.E. LaBerge (in Webb, 1980: 110) is presumably one of the ♀ specimens described by Robertson (1897: 340). Robertson (1903: 178-179) later provided a key that treated both sexes of N. simplex.
