Ventral surface. The caudal coxopleurae, flat, not extended, and 

 apically rounded in the eastern population of T. posticus (Shelley 1990a, 

 Fig. 6), are modified to some degree in the other species and most 

 individuals in the southwestern population of T. posticus. Conditions 

 vary widely, but the structures are usually elevated, produced slightly 

 beyond the caudal segmental margin, and typically have a variable apical
