protenus and parvifrons is very arbitrarily fixed, since specimens from 

 near Jeremie with 142 to 149 ventrals are called parvifrons, while others 

 from Miragoane and eastward with 149 or more are designated as 

 protenus. It seems best to keep these subspecific names, as a dif- 

 ference does appear to exist between the three forms in spite of the 

 integrading specimens.
