Introduction

The first boring bryozoan to be described was Terebripora ramosa from the coast of Brazil, establishing a new family (d'Orbigny 1841-1847). Pohowsky (1978) substantially revised the family, pointing out that confusion had arisen from reliance on description of the soft parts and neglect of the study of the boring system. In this family the autozooids are not pedunculate: the zooids adjoin the stolon at the proximal end, and become separate from it distally. The autozooid is subhorizontal; nearly parallel to the stolon and the surface of the shell. There is no peduncle, but there may be a thin planar zooidal extension, called a vane, connecting from the zooid to the stolon or the shell surface. In the genus Terebripora, the zooids are enantiomorphic, with the orifice either on the right or left side of the stolon. In the genus Marcusopora, known only from the Cretaceous, the zooid orifice is medial along the stolon, and the zooids are bilaterally symmetrical. Terebripora has been provisionally identified from Bass Strait. T. parasitica has been described from subantarctic material by Winston & Hayward (1994).
