Type species: Notaspis cassideus Hermann, 1804, by original designation
We have previously published a comprehensive diagnosis of this genus (Bloszyk et al., 2006). The only other genus in the family Cillibidae is Australocilliba. The two genera may be distinguished as follows: Cilliba: tarsus I without claws; metapodal line absent; epigynium of female without an anterior process; genital plate of male at level of coxae III-IV; Australocilliba: tarsus I with small claws; metapodal line distinct; epigynium of female with distinct anterior process; genital plate of male behind coxa IV. These and other differences between the two genera are also described in Athias-Binche & Bloszyk (1988).
On the basis of this diagnosis, we now recognise eight species of Cilliba. All occur in Europe and one (C. athiasae) extends into North Africa. Some authors have described species of Cilliba that are now placed in other genera, some species have been synonymised, and the placement of some other species cannot be determined because the available information is inadequate. The present composition of the genus is summarised in Table 1.
