Menke, Arnold S., 2007, Ammophila nancy Menke, a new species in the pruinosa complex (Hymenoptera: Sphecidae: Ammophilinae), Zootaxa 1546, pp. 31-38 : 37-38

Key to species in the pruinosa complex

1. Apex of folded proboscis reaching base of stipes, or surpassing it ( Fig. 10 ); if proboscis extended, then galea length from apex to palpal socket clearly longer than length of stipes (galea 1.14 X stipes length); female clypeus largely asetose, free margin usually arcuate (median lobe rarely defined by lateral teeth) and usually with narrow, median notch ( Fig. 5 ); legs black or red and black .................. californica Menke

- Apex of folded proboscis extending only about one half to three fourths distance to base of stipes ( Fig. 9 ); if proboscis extended, then galea clearly shorter than stipes (galea 0.68 to 0.78 X stipes length, rarely.0.9X); female clypeus with silver setae at least on upper half (fresh specimens), free margin variable, sometimes with weak teeth defining a median lobe, at most with broad, shallow median emargination ( Figs. 3–4 ); legs red and black..................................................................................................................... 2 2. Female flagellomere I length equal to about half lower interocular distance (FI.47–. 53X LID); female flagellomeres I–II as in Fig. 14 ; ventral process of penis valve head of male genitalia forming a C-shape ( Fig. 12 ); labrum apex rounded, sometimes acuminate apically in both sexes ................. pruinosa Cresson

- Female flagellomere I length equal to about 3/5ths lower interocular distance (FI 0.56–0.62X LID); female flagellomeres I–II slender, elongate ( Fig. 15 ); ventral process of penis valve head extending basad ( Fig. 11 ); labrum rectangular, apex straight, without median projection in both sexes nancy Menke , n. sp.
