Mendeschilis a new genus of Microcoryphia (Insecta, Apterygota, Machilidae) from Spain

A new species and genus of Microcoryphia is described as a result of the detailed comparison of specimens from Italy and Spain which had been initially identified as Praemachilis excelsior. The new genus, named Mendeschilis has as its most important distinctive taxonomic characteristic the presence, in the male, of parameres in the VIII^th and IX^th urosternites, while Praemachilis (from Italy) has only one pair of parameres in the IX^th urosternite. Other anatomical characteristics which allow us to differentiate the new genus and the new species are described.
