The discovery of this species is of much interest, as it gives the genua 

 Prostherapis a continental distribution. First detected in the extreme 

 north-west of the Colombian district, it has been identified by Boulenger 

 next from Ecquador,* and later from northern Peru.f To the present 

 time the latter is the most eastern locality known for it.
