Remarks. The specimens collected in the present study resemble those described in Kisielewski (1991) due to the presence of a bulbous pharynx and "ocellar" granules. However, they can be distinguished from those in Kisielewski (1991) for the absence of the dorsal cephalic sensorial bristle and the number of spines in the ventrolateral body side (8 against 12). Distribution. Brazil: Diamantina (Minas Gerais State), Jureia Ecological Reserve ( Sao Paulo State).
