Atetrapachylasma gen. nov.
Diagnosis. Wall of female of four plates ( Figs 11 View FIGURE 11 , 12 View FIGURE 12 ), compound rostrum (RLRRL), paired compound carinolatals (CL1CL2s) and carina (C); compound plates apparently without sutural traces in dwarf males as well as females. Wall low conical, wider than high; overall round plan constricted at sutures giving the four parietal parts a somewhat lobed appearance ( Figs 5 View FIGURE 5 , 11 View FIGURE 11 ). Opercular plates simple, triangular in outline, articular ridges and furrows weakly developed; tergum without depressor muscles crests; scutum with strong occludent ridge visible externally and internally, adductor pit and ridge absent.
Etymology. “A-” not, in preference to “Para-“ beside or near “, since despite also being four-plated and without traces of vestigial sutures, it is otherwise evidently not closely related to the type, Tetrapachylasma trigonum Foster, 1988: 225 , much less to Tetrapachylasma s.l.
