J. pygogramma, was described by Boulenger* ; the types 

 come from the Rio Cruz del Eje, Cordova, Argentina, and 

 the species is well distinguished from J. lineata by its 

 irregular scaling, the abdomen being naked and the scales on 

 the back much smaller than on the sides of the body.

In 1906 I described J. maculata f from Cachi, Salta, 

 Argentina, as a new species, and quite recently Haseman 

 has added J. eigenmanni J, a supposed new species from 

 the Rio Iguassu.
