Abstract
The second African species of the family Eutrachytidae is discovered and described as Mahnertellina paradoxa gen. nov., sp. nov. on the basis of two females from the Ivory Coast. The new genus is similar to DicornutophorusHirschmann, 1979, but the marginal shield of the new genus is reduced and the pygidial shield is absent, whereas in Dicornutophorus the marginal shield is complete and the pygidial shield is present.
Highlights
The family Eutrachytidae is a widely distributed group of Uropodina mites (Wiśniewski, 1993)
Marginal shield of dorsal idiosoma reduced at level of posterior processes
Notes: Up to now only one genus of the family Eutrachytidae is characterized by long posterior processes of the idiosoma: the genus Dicornutophorus Hirschmann, 1979
Summary
The family Eutrachytidae is a widely distributed group of Uropodina mites (Wiśniewski, 1993). During my visits to the Natural History Museum of Geneva numerous soil samples from Africa were investigated, and one sample from Ivory Coast contained two unusual specimens of eutrachytid mites which are described as a new genus. Marginal shield of dorsal idiosoma reduced at level of posterior processes. Setae v1 on palp trochanter situated on a long ventral and apically curved process.
