[New taxa in Psoroptinae. Hypothesis on the origin of the group (Acarina, Sarcoptiformes, Psoroptidae)].

Abstract

The author describes three new species and one new genus in the family Psoroptidae, subfamily Psoroptinae. A key is given to all the known genera of this subfamily. The fact that amongst the 16 species known from Africa South of the Sahara, 9 are endemic incites the author to believe that this group has a Centro-african origin.
