—In the present work, two groups of morphologically distinct specimens were identified, here recognized as two varieties. Different gradations were observed regarding the characteristics that separate them, evidencing some level of intersection between these two groups and, therefore, their incomplete separation.

We considered factors other than the phenetic approach to determine the most appropriate ranking for the allocation of the identified taxa since many delimiting morphological characters overlapped in the specimens.
