CYCLOPINIDAE Sars, 1913 sensu Martinez Arbizu, 1997 The Cyclopinidae s. l. complex is the most primitive within the Cyclopoid order (Ho, 1994; Martinez Arbizu, 1997). The unifying apomorphy of the representatives of this complex is the female fully fused genital double somite, although the value of this character has been reduced by the discovery of the genus Muceddina, which displays only partial fusion between genital and first abdominal somites (Jaume & Boxshall, 1997; Huys & Boxshall, 1990, 1991). From an ecological point of view representatives of the Cyclopinidae s. latu successfully colonized marine and brackish coastal habitats, littoral interstitial environments, hyperbenthic habitats, as well as they are well represented in the marine plankton, sea-ice crevices and anchialine caves. A few species have thus far been reported from inland fresh waters. Copepods of the family Cyclopinidae are known also from anchihaline caves and the hyperbenthos of the deep-sea (Jaume & Boxshall 1996, 1997; Martínez Arbizu 1997, 2000). Only one cyclopinid (Barathricola rimensis Humes, 1999) has been described from the hydrothermal vents (Humes 1999). Recently, Martinez Arbizu (ipers. com.) removed most genera from the old family Cyclopinidae, transferring them to other, new families of cyclopoids (Pterinopsyllidae, Psammocyclopinidae, Hemicyclopinidae, Smirnovipinidae, Cyclopettidae, Cyclopicinidae, Giselinidae, Schminkepinellidae). Karanovic (2008) still consider the genera Cyclopinella and Hemicyclopina in the family Cyclopinidae. The family Cyclopinidae Sars, 1913 was recently considered paraphyletic (Martínez-Arbizu, 1997, 2000, 2006) and split into eight families (Stoch, 2010) . Following Martinez-Arbizu's (2001) opinion, presently, the family Cyclopinidae should include the following genera: ALLOCYCLOPINA Kiefer, 1954 AFROCYCLOPINA Wells, 1967 ARENOCYCLOPINA Krishnaswamy, 1957 CRYPTOCYCLOPINA Monchenko, 1979 CUIPORA Ribeiro Lotufo & da Rocha, 1991 (syn.
