Remarks
This species resembles P. sideroicus Zeppelini & Brito, 2014 andP. ubiquum Zeppelini, Lima & Brito, 2018, in the shape of the subanal appendages and general body chaetotaxy but differ from all the species of the genus with records in this area by lacking the interantennal sensillar triangle, this feature seems to be shared by both the species of the queirozi-group and the ubiquum-group. The presence of only three chaetae in the dorsal cephalic area DII is also very unusual for the genus and the reduced number of chaetae in the dorsal posterior part of the great abdomen can be diagnostic for this species.
