taxonomic utility, but the presence of, usually, four large distal spurs, 

 one on each prefemur and femur, distinguishes T. californiensis from 

 T. posticus in California; the spurs are smaller, more on the order of 

 teeth, and there are consistently less than four total in the southwestern 

 population of the latter. To be certain of determinations of California 

 material, one should also examine the caudal coxopleurae, which almost 

 always have a sizable terminal spur in T. californiensis (Figs. 13-17) 

 and no adornment in T. posticus (Shelley 1990a, Figs. 7-11).
