Subfamily Cataeginae McLean and Quinn, 1987 Genus Cataegis McLean and Quinn, 1987

Type species: Homalopoma finkli Petuch, 1987 as senior synonym of Cataegis toreuta McLean and Quinn, 1987 ; original designation. Recent, Caribbean.

Discussion.— Cataegis was primarily described as a trochid of uncertain familial affinity ( McLean and Quinn 1987; Hickman and McLean 1990). Bouchet et al. (2005) included Cataeginae as a subfamily of Chilodontidae Wenz, 1938 in Seguenzioidea . Recent molecular investigations by Kano (2008) revealed that Cataegis indeed goes to Seguenzioidea ;

the remaining family Chilodontidae appears to be a polyphyletic taxon and needs further investigations.

Distribution.— Cataegis includes deep water species known from the Caribbean ( McLean and Quinn 1987; Hickman and McLean 1990; Warén and Bouchet 1993) and from the Pacific (McLean and Quinn 1990; Fu and Sun 2006). At least one species, C. meroglypta McLean and Quinn, 1987 is known from hydrocarbon seep on the Louisiana Slope ( Warén and Bouchet 1993; García 2002; Gill et al. 2005). Cataegis sp. has also been found in seeps off Costa Rica (Anders Warén, personal communication 2009). Gill et al. (2005) reported occurrences of C. meroglypta from Cenozoic Caribbean seep carbonates. The species has been identified in the Oligocene or Early Miocene Sub−Oceanic Fault Zone seeps of Barbados and also the Miocene Freeman’s Bay Limestone seep fauna ( Gill et al. 2005). Moroni (1966) reported Phasianema taurocrassum Sacco, 1895 from the Miocene “Calcare a Lucine” (seep carbonates according to Taviani 1994 and Peckmann et al. 1999) which is quite similar to Cataegis .
