Distinguishing features: Bicyclic, large; bar simple (formed of one unit); rim narrow/openings large


Morphology remarks: A large species of Zeugrhabdotus in which the slender, disjunct bar, which is crystallographically uniform, divides the wide, open central area. Differentiation: This new species is distinguished from other zeugrhabdotids in having a simple, slender bar dividing the wide, open central area. [Lees 2007]

Size: Holotype dimensions: L = 8.80μm, W = 6.16μm.
