Figure 12; Comparisons of opercular plates (fused scutum and tergum) of Galkinius maculosus sp. n. among species in Darwiniella and Galkinius. Note the height of adductor plate (indicated by double arrows) is much greater in Darwiniella than Galkinius species. The spur of tergum (indicated by single arrow) is sharper in Darwiniella than Galkinius. The opercular plate of G. maculosus sp. n. is closer to species in Galkinius.
