Oribatid mites (Acari: Oribatida) from the coastal region of Portugal.
I. Peloptulus sacculiferus n. sp., an aberrant species of Phenopelopidae compared with similar European species of the genus


A new species of oribatid mites, Peloptulus sacculiferus n. sp., was found in coastal meadows adjacent to  salt  marshes  and  is  described  in  this  paper.  The  species  has  notogastral  sacculi  instead  of  areae porosae, which is unique within the family. The new species is distributed in Portuguese coastal habitats of the Minho River, of the Lagoon of Aveiro and in the south-western Algarve at Cabo São Vicente, but it avoids the salt marsh area. A related species, Peloptulus reticulatus Mihelčič, 1957, occurs at the border of salt marshes in the Lagoon of Faro in southern Portugal. This species is re-described, and P. trinacriae Arcidiacono,  1975,  from  coastal  dunes  in  Sicily  is  declared  a  new  junior  synonym  of  P. reticulatus.
