1918 Phillipsia woodwardi ?; Mitchell, pl. 51, fig. 14, pl. 52, fig. 1.
1984 Conophillipisa subquadrata Engel & Morris; p. 50–53, figs. 16–17.
Holotype. AMF80575 (external mould of cranidium).
Paratype material. From NSW 58–12: AMF80574 (partial internal pygidium), AMF80576a/b (external/ internal pygidium), AMF80577a/b (external/internal pygidium). From NU L39: AMF80572 (external pygidium), AMF80573 (external pygidium), AMF80578 (internal pygidium), AMF80579 (internal librigena), AMF80580 (internal pygidium), AMF80581 (internal cranidium), AMF80582 (internal pygidium), AMF80583 (external pygidium), AMF80584 (internal pygidium), AMF80585 (internal pygidium), AMF80586 (internal pygidium), AMF80587 (partial internal thorax), AMF80588a/b (external/internal pygidium), AMF80589 (external pygidium), AMF80590a/b (external/internal pygidium), AMF80593 (external pygidium), AMF80594 (external pygidium), AMF80595 (internal pygidium), AMF80596 (external librigena), AMF80597 (internal pygidium), AMF80598 (external pygidium). From NSW 112–6: AMF80591 (internal pygidium), AMF80592 (internal pygidium). From QGS L3004: QGSF 1017 (external cranidium), QGSF 1031 (external pygidium), QMF2839 (external pygidium).
Locality. Type—NSW L58–12. Others—NU L39, NSW L112–6, QGS L3004.
Emended diagnosis. Rounded genal angles; glabellar length equal to width, moderately convex. Pygidium broadly parabolic, convex axis; border convex; 13+ axial rings; 10–11 pleural ribs; ring furrows straight; lateral lobes on axis.
Remarks. The diagnosis is emended to remove the length of the glabella, as this is uncertain in the available specimens. Monodechenella subquadrata appears to be most similar to Monodechenella grandis (Etheridge Jr. 1892a) (see M. grandis remarks below for a detailed comparison).
