San José and San Francisco de los Rios, 1100 metres above the sea, in the hedges

This species looks somewhat like the European P. rupestris. Strebel suggests * that 
its riblets may be provided with cuticular lappets or hairlets in a very fresh state, which 
would bring it near the following section, Thysanophora. 
c. Cuticular lamellae in oblique rows, crossing the riblets. Spire more or less raised ; 
whorls rounded or scarcely subangulated ; umbilicus moderate or rather narrow.
