Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| K. J. McNamara et al. 2009 (Globoharpes) | Cephalon very vaulted, with strongly tapering prolongations; brim and genal roll both strongly convex and steeply inclined sagittally, less so laterally. Girder very distinct and smooth. Prominent large preglabellar boss, as wide as posterior of glabellar, on genal roll in some morphotypes. Genal area of low convexity. Eye lobes anteriorly positioned. Eye ridges broad, short and weak. Glabella small, strongly vaulted. Ala prominent; alar furrows and posterior alar depression deep. Posterior border furrow broad and shallow. Brim, genal roll and prolongations with irregular but prominent pitting, except on lateral genal roll, where more radially aligned. Genal area, occipital ring and glabella ornamented with fine granules. Hypostome, thorax and pygidium unknown. | |
| R. G. Johnson 2024 | Glabella inset and narrow, width (tr.) being less than 67% of length (sag.). Preglabellar
furrow straight in anterior view. Alae small, posterior border wide (tr.). Fine granulation on glabella, occipital ring and genal area. Inner margin of fringe marked by narrow, faint furrow. Genal roll sloping gently anteriorly, at under 500, more steeply laterally at over 550. Perforations on genal roll smaller than brim perforations. On brim, spaces between perforations strongly inflated. In lateral view, prolongations are strongly tapered, with internal and external rims joining to form long genal spines. |
