Genus Cychrus Fabricius, 1794

Cychrus Fabricius, 1794a: 440. Type species: Carabus rostratus Linnaeus sensu Fabricius, 1775 (= Tenebrio caraboides Linnaeus, 1758) designated by Latreille (1810: 426). Etymology. Uncertain, possibly from Cychreus , son of Poseidon and Salamis, or from Cychros , a city in Thrace near a lake whose water was unhealthy [masculine]. Duméril (1823: 167) stated that Cychros was the name of a bird (probably in Pliny the Elder) but I have not been able to confirm this. Note. Fabricius (1794b: 70) used the spelling Cychrys for this genus in another publication issued the same year. Dates of publication of both works are unknown besides the year. Bousquet (2002b: 16) acted as First Reviser and opted for Cychrus as the valid name.

Diversity.

Northern Hemisphere, with about 115 species (Lorenz 2005: 64-66) in the Nearctic (two western species) and Palaearctic Regions.

Identification.

Gidaspow (1973) revised the North American species. Lindroth (1961a: 25-26) covered the species in his monograph of the Canadian and Alaskan Carabidae .
