maroniella Dyar and Heinrich 



Tonguelike projection distinctly bifurcate above ventral margin of the 



ostium 7

cave gloriella Schaus 



Tonguelike projection with median area of bifurcation strongly angulate, 

 apices blunt albescens, new species 



10. Signa rather large, slender and thornlike; length of the spine approximately 



two times the diameter of its base quiriguella Schaus 



Signa much shorter, spinelike or subconical 11 



11. Ductus bursae with accordion-like folds from ostium to the loop and distinctly 



tapered from ostium to the loop squamulella (Zeller)

conical, bluntly pointed cochisensis, new species 



Ventral margin of ostium without a median finger-hke production. Signa 

 sharply pointed, spinelike 13
