A potential revision of the <i>N. echinatinodis</i> complex could either result in the synonymization of certain species or the division of the complex into multiple forms. It is common to find <i>N. echinatinodis</i> exhibiting sculpture similar to that of <i>N. spininodis</i>, particularly in populations from Colombia different from those living in the TDF (Unpublished data). Additionally, coloration is highly variable within the <i>echinatinodis</i> complex. For this reason, using coloration as the primary criterion for distinguishing between different forms is not recommended. Thus, the separation of both species should not rely solely on coloration; instead, the sculpture of the frontal area of the head and the first gastral tergum should also be compared.</p>
