FIGURE 1. Tetraclitella spp. A–E: Tetraclitella judiciae sp. nov. A: RM 318–latus (exterior); B: RM 318–latus (interior), the central, large, ellipsoidal structure is a grain of calcite, that if removed may have damaged the plate. It is not part of the barnacle; C: P313914–detail showing eroded radius of left latus (central cavity on image), and ellipsoidal pattern produced by eroded parietal pores intersecting the exterior surface; D: P313914–detail showing basal section through the shell wall, with inner row of large, elongate pores and outer multi-porous zone; E: P313914–detail showing parietal pores that have been apically infilled; F: Tetraclitella purpurascens purpurascens (Wood, 1815): Basal view of parietes exposing edge of sheath (upper, unpatterned zone) and multi-porous zone that lacks a distinct inner row or larger, elongate pores.
