Rhabdopleura Allman in Norman, 1869

Type species. Rhabdopleura normani Allman in Norman, 1869, Shetland, by monotypy .

Diagnosis (emended after Maletz 2014). Colonial pterobranchs with fundamentally encrusting, rarely free, tubular constructions with semi-regular to irregular fusellar rings and, in encrusting parts, generally regular zigzag sutures. Erect tubes parallel-sided, originating directly from resorption sites on creeping (or otherwise axial) tubes or indirectly and terminally from a creeping tube via an intervening adnate portion; the latter plus the erect tube comprising a blind-ending side branch. Zooids connected via a robust stolon system (black stolon). Sicular zooid secretes a featureless domal prosicula.
