A new genus and two new species of Canthocamptidae (Copepoda, Harpacticoida) from caves in northern Italy

Lessinocamptus n. gen. is established to accommodate three species from northern Italian caves. It can be ascribed to the family Canthocamptidae Sars 1906 and is distinguished from the other genera by the combined characters of: antenna exopod 1-segmented and bearing 3 setae (or I seta and I spine); mandibular palp 2-segmented with distal article bearing 5 setae; swimming legs exopods 3-segmented; setal formula of exopods: P1 0.0.022; P2 0.1.112; P3 0.1.212; P4 0.1.212; P1 endopod 2-segmented; P2 endopod 1- or 2-segmented; female P3 endopod 1- or 2-segmented, male P3 endopod 3-segmented and modified as usual in Canthocamptinae; male P5 baseoendopod with 2 spines and exopod with 3 spiniform setae. Three species are described in detail: L. caoduroi n.sp. from the vadose zone of Lessinian caves, L. insoletus (Chappuis 1928) and L. pivai n.sp. from cave 'Buso della Rana' near Vicenza.
