Turbonillacoomansi nom.nov. is proposedforChemnitziapusillaC.B.Adams, 1850, non C.pusilla
Philippi,1844.Two earliernominanova appeartobe homonyms.
Key words: Gastropoda, Opisthobranchia, Pyramidellidae,Turbonilla, taxonomy, synonymy,
Atlantic Ocean, West Indies.
The well-known Caribbeanpyramidellid Turbonilla pusilla (C.B. Adams, 1850) was
originally describedin the genusChemnitzia d'Orbigny, 1840.Unfortunately the name
Chemnitziapusilla C.B. Adams, 1850,is aprimary homonym ofC.pusilla Philippi, 1844,
oneofthe morecommon European species ofTurbonilla.Becauseofthispreoccupation,
the replacement nameT. minorwasproposed by Bush in1899.Thisnameis usede.g. in
the recent book by DeJong & Coomans (1988: 126).
However, the name T. minor Bush, 1899, is again preoccupied, viz. by T. minor
Seguenza, 1876.ThereforeBush'sname cannot be used. A second replacement name
was proposed for T. pusilla (C.B. Adams, 1850), viz. T. adamsiCossmann, 1912,which
nameis aprimary homonym ofT. adamsiClessin, 1902,andthus cannot beusedeither.
Theconclusion canonly be that T.pusilla (C.B. Adams, 1850) is stillinneedofa new
name, forwhich Ipropose Turbonillacoomansiafter Dr.H.E. Coomans ofthe Zoologisch
Museum, Amsterdam.
