long (sag.). Cranidium trapezoidal in outline, length:width ratio approximately 53%, maximum width across posterior limbs of fixigenae, narrowest point of cranidium at the anterior margin; strongly convex (sag., tr.). Anterior margin straight (tr.). Posterior margin bowed anteriorly, except for the occipital ring that bulges posteriorly. Anterior branches of facial suture (γ–β) are difficult to distinguish. Glabella long (sag.), anteriorly truncate, trapezoidal in outline, strongly convex, with maximum convexity across midwidth, lateral slopes gently convex; width:length ratio of 71% to 74% (mean 72%; n = 3), occupying 89% of the cranidial length. Axial furrow narrow (tr.) and deep. S1 well defined, deep and narrow (exsag.), intersecting axial furrow approximately level with ε, directed slightly posteromedially for a short distance, before bifurcating with the anterior branch traversing a small distance anteromedially before becoming indistinct and the posterior branch continuing posteromedially. S2 and S3 short; S2 is directed posteromedially, whilst S3 is directed anteromedially. Occipital ring of moderate length (sag.), becoming slightly narrower abaxially, posterior margin strongly bowed backwards. SO wide (exsag.), straight to slightly bowed backwards medially in some individuals, moderately deep (sag.) and deepening abaxially. Anterior cranidial border narrow (sag.), moderately convex, slightly upturned. Anterior border furrow deep and wide (sag., exsag.), with deeper (possibly apodemal) pits situated at the anterolateral corners of the glabella. Preocular field, strongly convex, strongly downsloping toward the anterior border furrow, 21% of sagittal cranidial length between the anterior border and γ. Palpebral lobes reniform in outline, defined by a narrow (tr.), shallow palpebral furrow, anterior tip situated opposite S2, posterior tip situated opposite L1. Eye ridge weakly defined on external surface, slightly more defined on exfoliated surfaces, extending posterolaterally from just anterior to S

a slightly anteriorly curved line towards the anterior tip of palpebral lobe. Palpebral area of fixigena slightly convex, downsloping towards the axial furrow, maximum width (tr.) is adjacent to 92% of the glabellar width. Postocular field moderately long (exsag.) and strongly downsloping toward the posterior border furrow. Posterolateral projections of fixigena strongly downsloping. Posterior border narrow (exsag), widening abaxially, separated from fixigenal field by deep, wide (exsag.) border furrow. Posterior border furrow straight proximally, then directed posterolaterally to ε.

Posterior margin curved slightly forward distally before abruptly curving rearwards to become the inner margin of the genal spine. Genal field subtrapeziform, 75% of librigenal width (tr.) along posterior border, moderately convex. Lateral border moderately well defined, widest near the posterior border. Lateral and posterior border furrows wide (exsag.) and moderately deep. Low eye socle present, separated from librigenal field by wide, shallow eye socle furrow.

long (sag.), subtrapezoidal in outline excluding spines, moderately convex, sagittal length:width ratio of 47% to 54% (mean 50%; n=4) excluding spines. Anterior margin slightly curved, with the articulating half-ring being slightly convex. Axis prominent, moderately narrow (tr.), moderately tapered posteriorly, width:length ratio of 70%, occupying about 85% of sagittal length of pygidium. Articulating half-ring incompletely preserved, appears to have been short (sag.). Four well defined axial rings present, separated by deep, wide (sag., exsag.) inter-ring furrows; a faint fifth axial ring present in some specimens, separated from the terminal piece by a poorly developed inter-ring furrow. Terminal piece short (sag.). Axial furrow deep and wide (tr.). Pleural regions slightly convex, with four wide (exsag.), moderately deep pleural furrows. Furrows are contiguous with the lateral extremities of the axial rings; anterior furrows directed slightly backwards from the axial furrow and distally curved backwards, and becoming shorter and more backwardly directed posteriorly, terminating before reaching margin. Pleural ribs strongly convex. Faint, shallow, narrow (exsag.) interpleural furrows on first and second pleural ribs, extending the entire length of the rib. Border of moderate width (sag., exsag.), defined by change in convexity from the pleural region; with seven pairs of spines, first and fifth pair are considerably longer and proximally wider (tr.). Anterior first to fourth pair of spines extending posterolaterally and become progressively more backwards pointing towards the tips. Posterior sixth and seventh spine pairs directed straight back.

This taxon was originally reported as “Damesellinae, fragments” from Ross River Gorge at locality NT187 by Öpik (1967, appendix 2, p. 16). The specimens from the GOY section and locality 87-008 are remarkably similar, although librigenae from the former site exhibit a slightly shorter genal spine. This minor difference is either ontogenetic (the 87-008 specimens are slightly larger) or taphonomic (GOY specimens are preserved in limestone rather than a coarse sandstone). The GOY specimens also exhibit minor variation in the degree of glabellar taper during ontogeny. The lateral glabellar margins of smaller holaspid specimens converge anteriorly at approximately 20° (
