Type-species: Tachytes obscunis Cresson. Orig. desig. 



Members of this genus are ground-nesting and usually construct multicellular nests. Some 

 species begin their burrows in pre-existing holes such as rodent burrows or abandoned burrows 

 of large insects, whereas others excavate their burrows from the ground surface. Members of 

 the Aurulentus Species Group prey on katydids (Tettigoniidae), those of the Pepticus and 

 Distinctus Groups use grasshoppers (Acrididae), species of the Abdominalis Group prey upon 

 grasshoppers, grouse locusts (Tetrigidae) and pygmy mole crickets (Tridactylidae), and the Mer- 

 gus Group uses only pygmy mole crickets. Members of the extralimital Ambidens Group have 

 been observed preying upon geometrid caterpillars.
