On some Collembola from a Sicily cave, with the description of a new species of Serroderus Delamare, 1948 (Collembola, Cyphoderidae)

This paper deals with some cave collembola from Sicily. The analysis has revealed the presence of the species Acherontiella carusoi Dallai, 1978, Heteromurus nitidus (Templeton, 1835), Disparrhopalites patrizii (Cassagnau and Delamare, 1953), and Serroderus trinacriae n. sp., new to science. This is the first record of the genus Serroderus for Sicily and Italy. The new species is characterized by the multidentate shape of the mucron, the presence of three to four spines, and by the number of scales on the inner (five) and outer (eight) rows of the dens. The biogeographical distribution of the genus and the taxonomic relationships of S. trinacriae n. sp. are discussed.
