Key to Genera of Ammophilini

from BOHART & MENKE 1976, slightly modified

1. Episternal sulcus curving back to scrobe from subalar fossa, then extending obliquely ventrad to anteroventral area of mesopleuron ( Fig. 1 ); New World forms .... ..................................................................................................... Eremnophila MENKE

- Episternal sulcus extending straight down from subalar fossa (in some species absent), not passing through scrobe ( Fig. 2 ) ................................................................ 2

2 Claws in most specimens simple but if with single basal tooth on inner margin then mouthparts very long, galea attaining base of stipes when folded ...............................3

- Claws with one or two basal teeth on inner margin; galea not extending beyond stipes midlength when folded and in most specimens shorter; Old World forms ........ 4

3. Apex of sternum I (petiole) meeting and in many specimens overlapping base of sternum II ( Fig. 3 ); spiracle of tergum I located before apex of sternum I (in profile); petiole in many specimens bent upward at level of base of tergum I.................... ....................................................................................................... Podalonia FERNALD

- Apex of sternum I not reaching base of sternum II, intervening space mostly long and consisting of membrane and ligament ( Fig. 4 ); spiracle of tergum I located at or beyond apex of sternum I; sternum I in many specimens bent downward or straight at level of base of tergum I............................................. Ammophila W. KIRBY

4. Mesothoracic venter with anteromedian projection behind forecoxa; petiole socket nearly completely surrounded by propodeal tergum ( Fig. 6 ); inner orbits of female strongly converging below; midtibia with single spur .............. Eremochares GRIBODO

- Mesothoracic venter without anteromedian projection, at most obtusely angled (exception: Parapsammophila foleyi ); petiole socket broadly bounded ventrally by T-shaped propodeal sternum ( Fig. 5 ); inner orbits of female only slightly converging below or parallel or diverging below; midtibia with two spurs (one may be reduced or absent) ........................................................................................... 5

5. Foretarsomere I of female strongly asymmetrical, its outer apex prolonged ( Fig. 9 ); free margin of male clypeus rounded or truncate; tarsi in most specimens with arolia; male gonostyle of usual shape ....................... Parapsammophila TASCHENBERG

- Foretarsomere I of female nearly symmetrical, outer apex only slightly produced (fig. 10); male clypeus triangular; arolia absent; male gonostyle of unusual shape ( Fig. 8 ) ......................................................................... Hoplammophila DE BEAUMONT
