Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. J. Holloway 2005 | Phacopinae of small to moderate size. Composite lobe of glabella moderately to strongly convex, slightly overhanging anterior border; axial furrow very deep in front of L1; S1 deflected forwards adaxially and obsolete medially; L1 with relatively broad depressed region between lateral node and strongly elevated median swelling that appears attached to back of composite lobe. Cheek narrower (tr.) than glabella across occipital ring. Eye very small, situated low on front of inflated genal field, with lower edge in or just above lateral border furrow; length (exsag.) of eye greater than or equal to postocular length of genal field; palpebral furrow deep, slightly convex adaxially; palpebral lobe very narrow, forming part of convex rim surrounding visual surface; visual surface elliptical to subquadrate in outline, with 9-19 lenses of somewhat uneven size arranged in slightly irregular vertical files of 1-4 lenses each. Lateral border furrow deep, at intersection with postocular furrow flexed rather abruptly upwards to meet posterior border furrow; lateral border expanding strongly backwards, well-rounded (tr.), lacking marginal ridge; cephalic margin truncated or embayed at genal angle. Vincular furrow notched laterally, deep medially. Pygidium with axis as wide (tr.) or almost as wide anteriorly as maximum pleural width. Sculpture of coarse, smooth tubercles on composite lobe of glabella and genal field; medial part of cephalic doublure with fine, dense granules posteriorly, grading into scaly granules and short ridges anteriorly and on lateral part of doublure; pygidium smooth or weakly tuberculate. |
