, separating the three valid species according to their size and position of the cephalic setae, the position of the apical organ or cirri, and the size of the tail in relation to the anal body diameter. In the mentioned taxonomic key, authors used the term “lateral cephalic setae” to differentiate species; however, this setae position is not expected to occur because amphids are placed in the lateral position of the third ring of sensory organs. Then, these lateral setae are maybe lateral subcephalic setae that migrate to the cephalic setae circle. These authors also suggested that
