Map 29.8. Distribution of Rhithrodytes.

Genus Siettitia Abeille de Perrin, 1904

Body Length. 2.2–2.5mm.

Diagnosis. These are subterranean, flightless, depigmented, and microphthalmic siettitiines (Fig 29.14). They can be diagnosed from most other subterranean members of the group (except Stygoporus and Etruscodytes) by the presence of incised lines on each side of the pronotum (Fig 29.14). Siettitia differ in the prosternal process not reaching the metaventrite.

Classification. Little to nothing is known of Siettitia relationships, though they have been regarded as possibly closely related to Rhithrodytes and Iberoporus (Castro and Delgado, 2001; Ribera and Faille, 2010).

Diversity. There are two species in Siettitia, S. avenionensis Guignot and S. balsetensis Abeille de Perrin.

Natural History. Siettitia are subterranean and have been collected from wells in southern France.
