A new genus and a new species of a troglobitic Cixiidae from Sicily are described. Ibleocixius gen. n. differs from Cixius and related taxa in a different arrangement of several characters which are also present in other taxa. Characters at genus level lie in the peculiar morphology of the aedeagus which has only one movable spine, a longitudinal sclerotized ridge on the right side and the characteristic sclerotized areas along the margins and on the left side; in females the transition between the wax plate and the lateral abdomen is very peculiar, forming a rather rounded angle; tergite IX bearing a wax plate partially divided in two portions. The new species, Ibleocixius dunae sp. n., has strongly reduced eyes, the forewings are slightly and the hind wings strongly reduced; the body is partially covered by wax granules that pile up waxflakes mainly along the wing margins. Special characters pertain to the structure of the male and female genitalia. The new species up to now is known only from a single limestone cave of the South-eastern Sicily.

Abstract

A new genus and a new species of a troglobitic Cixiidae from Sicily are described. Ibleocixius gen. n. differs from Cixius and related taxa in a different arrangement of several characters which are also present in other taxa. Characters at genus level lie in the peculiar morphology of the aedeagus which has only one movable spine, a longitudinal sclerotized ridge on the right side and the characteristic sclerotized areas along the margins and on the left side; in females the transition between the wax plate and the lateral abdomen is very peculiar, forming a rather rounded angle; tergite IX bearing a wax plate partially divided in two portions. The new species, Ibleocixius dunae sp. n., has strongly reduced eyes, the forewings are slightly and the hind wings strongly reduced; the body is partially covered by wax granules that pile up waxflakes mainly along the wing margins. Special characters pertain to the structure of the male and female genitalia. The new species up to now is known only from a single limestone cave of the South-eastern Sicily.
