A peculiar new virus-spermatozoon association in the bug Raphigaster nebulosa (Poda) (Heteroptera-Insecta)
No full textThe sperm of the heteropteran bug Raphigaster nebulosa (Poda) are of two types, differing in length and size of their flagella. The thicker sperm are shorter than the thinner ones and have large mitochondrial derivatives. The presence of virus particles associated with the plasma membrane of thinner sperm is described for the first time; thicker sperm are immune to virus infection. The fact that virus particles are present on thinner sperm only initiates considerations on the transmission of virus

No full textThree new species of Collembola belonging to three different families were described from the Cansiglio Natural Reserve (north-east Italy): Hypogastrura pizzoci sp. nov. (Hypogastruridae), Endonura saleri sp. nov. (Neanuridae) and Pseudosinella cansiliensis sp. nov. (Entomobryidae)
A new cave species of Deuteraphorura (Collembola Onychiuridae Onychiurinae) from central Italy.
No full textViene descritta una nuova specie cavernicola di Collembolo Onychiuridae: Deuteraphorura ba- nii n. sp. (mf, loc. typ.: Grotta dei Cinque Laghi, Monte Nerone, prov. Pesaro-Urbino). La nuova specie è caratterizzata dalla peculiare combinazione della formula dorsale (32/033/33353) e ventrale (3/011/2212) degli pseudocelli che ne permette la facile identificazione rispetto alle altre specie del genere

Heteromurus nitidus
No full textHeteromurus nitidus (Templeton, 1835) Material. Numerous individuals found in different sites of the cave. Heteromurus nitidus is a troglophilic species with holarctic distribution. It has been reported from numerous localities along the Italian peninsula (Dallai et al. 1995) both from soil samples and caves (Dallai and Malatesta 1982) where it usually occurs as a typical element.Published as part of Fanciulli, Pietro Paolo, Caruso, Domenico & Dallai, Romano, 2006, On some Collembola from a Sicily cave, with the description of a new species of Serroderus Delamare, 1948 (Collembola, Cyphoderidae), pp. 1241-1251 in Journal of Natural History 40 (19 - 20) on page 1243, DOI: 10.1080/00222930600803241, http://zenodo.org/record/522757
