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.
