Diagnosis
ReferenceDiagnosis
P. J. Lespérance and D. Desbiens 1995Encrinurines with variable width: length glabellae and equally variable outlines of lines joining tips of L2-L3- L4 lobes; glabellae with 50-90 tubercles, tubercle pairs symmetrical across (tr.) LI and L2, and rarely L3 lobes, in some species (lapworthi, rarus, and gelaisi n. sp.), without symmetry in the others; short anterior cranidial borders in dorsal view, with omnipresent tubercles; with short genal spines (except lapworthi) and hypostomata with elongated middle bodies (except rarus); pygidia with subequal width-length ratios, 17-21 axial rings, 7-9 pleural ribs, and 1-2.5 congruent pleural ribs and axial rings.
D. K. Moss and S. R. Westrop 2014Strongly expanded, “mushroom-shaped“ glabella (character 1, state 1), strongly perforated, small tubercles in the 1L-1, 2L-1, and 3L-1 positions (character 9, state 2), and a relatively narrow pygidium whose length is greater than 90% of maximum width (character 23, state 2).
