This redescription is based on Hull’s (1947b) original description. The information available in the original description is inadequate to clearly distinguish

cyclops
from similar species. In Hull’s 1949a key
P
.
cyclops
keys out as ‘Alula near or quite as wide as the basal part of costal cell […]’ (page 108, couplet 54), which suggests that the alula is much wider than on

aster
, although this information is not present in the original description.
