Abstract
ABSTRACT Phenotypic characters of the uncommon Dimya cf. japonica, based on a specimen from Niue Is. in the South Pacific, are reported to represent the enigmatic Dimyidae in a wide-ranging Bivalvia phylogenetic scenario. The main conclusion is that dimyids are placed between ostreoideans and pectinoideans. This is supported by five synapomorphies. Dimyids are closer to pectinoideans, in that they share four synapomorphies.
期刊介绍：
Malacologia publishes papers on all groups of the Mollusca. Malacologia specializes in publishing long papers and monographic treatments. Complete data are especially appreciated. Papers must be of interest to an international readership. Papers in systematics, ecology, population ecology, genetics, molecular genetics, evolution and phylogenetic treatments are especially welcomed. Also welcomed are letters to the editor involving papers published or issues of import to science of the day.
