Interchangeable taxa

The more broadly conic form of this species serves to separate it from similar species such as T. lazaroensis Bartsch and T. cholutecana in which the shells are exceedingly slender.
The specific name of this species is derived from the name of the state of Chinandega, Nicaragua.
