Remarks .—Molecular data indicate that species currently assigned to Pliocardia (cf., Krylova and Sahling 2010 ) belong to two distinct clades ( Audzijonyte et al. 2012 ; Valdés et al. 2013 ; Johnson et al. 2017 ). The first clade includes “ Pliocardia ” cordata and “ Pliocardia ” ponderosa and is referred to as “ Pliocardia 1” by Valdés et al. (2013) and as “ cordata group” by Johnson et al. (2017) . The second clade includes P. kuroshimana and P. crenulomarginata and was called “ Pliocardia 2” by Valdés et al. (2013) and “ Pliocardia ” by Johnson et al. (2017) . It remains unclear, however, to which, if any, of these two clades the fossil type species belongs. Hence, we use Pliocardia here in inverted commas only.
