Description of 2 new species of Unjapyx Silv.: U. turbator from Italy
and U. mussardi from Morocco, both very close from U. simplicior (Silv
.) from Italy or U. clayae Pgs. from Corsica. These 4 species could be
distinguised by their abdominal chetotaxy, the cerci, and, concerning
only the male, the absence or presence and the number of glandular pi
ts on abdominal sternites.
