7. Costa of dorsal basal lobe triangularly produced. Aedeagus with a toothlike 



production from near middle of a long, straplike sclerotization. 



placidella (Haimbach) 

 Costa of dorsal basal lobe round. Aedeagus without a toothlike production. 



dumptalis Schaus 



8. Distal projection short, length not more than twice its width; apex truncate. 



indistinctalis, new species 

 Distal projection otherwise 9 



9. Dorsal basal lobe with a small, sharp, toothlike production on costal margin 



albescens, new species

margin floridalis, new species 



10. Uncus with two conspicuous, long, slender, modified setae at apex. 



pallescens, new species 

 Uncus otherwise 11 



11. Hook of right harpe curved serpentine-like. Aedeagus with a distal cluster of 



rather strong spinules squamulella (Zeller) 



Hook of right harpe with curvature otherwise. Aedeagus without a cluster of 

 spinules 12 



12. Hook of right harpe with dilation near middle distinctly angulate. Aedeagus 



long, slender, undulate; width at apex distinctly less than at base. 



diminutalis, new species 



Hook of right harpe with dilation near middle, rounded. Aedeagus shorter 



and stouter than above, straight or nearly so and width at apex and base 



approximately equal 13 



13. Hook of right harpe broadly expanded basally; distal part straight or nearly 



straight, stout and bluntly pointed prestonella Schaus 



Hook of right harpe not so broadly expanded basally; distal part distinctly 

 curved, more slender and more sharply pointed than above. 



arizonensis, new species 



Key to Species of Haimbachia Based on the Female Genitalia 



1. Signum or signa present 3

2. Tonguelike projection with median area of the bifurcation angulate, acute 



and rather deep; the projection divided, slitlike from base of bifurcation to 



near the loop diminutalis, new species 



Tonguelike projection with median area of bifurcation broadly concave; the 

 projection undivided from base of bifurcation to the loop. 



pallescens, new species
