Notes
145 records
This species was described from the Northeast Atlantic when Angel (1971) showed that the prevailing concept of Conchoecia procera was a complex of three species, with consistent differences in their carapace sizes. Poulsen (1973) placed C. procera in the Claus’s genus Paraconchoecia, but Kock (1992) reclassified all the species originally in Muller’s ‘procera group’ in a new genus Proceroecia, and designated macroprocera as the type species. This is the largest of the three species. The bathymetric profiles show that it occurs at depths of 50-300m at 10-18°N, but deeper on the equator, i.e. slightly deeper than the other two sibling species. Its distribution map shows its latitudinal range to be 60°N-52°S, although distribution of records is unlikely to be representative. It has recently been reported from the Aegean Sea.
