Nepa is a genus belonging to the family Nepidae, known as water scorpions. There are six species found in freshwater habitats in the Northern Hemisphere.[2][3]
They are oval-bodied, aquatic insects with raptorial front legs. Like other members of the Nepidae, they have a pair of nonretractable cerci-like breathing tubes on the terminal abdominal segment, a characteristic which readily distinguishes them from the Belostomatidae. Their primary staples are other insects and small aquatic vertebrates. They can inflict a painful bite when handled.[4]
Etymology
[edit]'Nepa' is a classical Latin word for a 'scorpion' or 'crab'.[5]

The following species are included in Nepa:[2][3][6][7]
- Nepa anophthalma Decu et al., 1994 (see Movile Cave)
- Nepa apiculata Uhler, 1862
- Nepa cinerea Linnaeus, 1758 - type species
- Nepa dollfusi Esaki, 1928
- Nepa grandis Linnæus, 1758
- Nepa hoffmanni Esaki, 1925
- Nepa monteilsensis Nel, 1988
- Nepa plana Sulzer, 1776
- Nepa remyi Poisson, 1961
- Nepa rubra Linnaeus, 1758
- Nepa rustica Fabricius, 1775
- Nepa sardiniensis Hungerford, 1928
- Nepa seurati Bergevin, 1926
Among these, N. apiculata of eastern North American (Canada and United States), and N. cinerea of Europe, northern Africa and northern Asia, are widespread.[2][4] The remaining have restricted ranges in Corsica, Sardinia, Romania, Morocco and northeastern Asia.[2][3] One of these, N. anophthalma, is the only cave-adapted species in the family Nepidae, found in Movile Cave.[3]
Linnaeus listed a number of additional species in his description of the genus, most of which either are considered synonyms or have been moved to other genera.
