摘要

The taxonomy of cyclostome bryozoans, both recent and fossil, is founded almost entirely on characters of the mineralized skeleton. However, the adequacy of these characters is now being questioned by molecular sequence data. In this study we construct a molecular tree using ssrDNA and lsrDNA sequences and identify a clade of New Zealand cyclostomes containing species exhibiting widely different morphologies. In particular, Diaperoecia purpurascens (Hutton), a species assigned to the suborder Tubuliporina on the basis of adult skeletal morphology, is shown to be closely related to New Zealand species assigned to Heteropora, including H. neozelanica (Busk), which has a very different adult skeleton and is traditionally placed in the suborder Cerioporina. A new species resembling the Antarctic genus Hastingsia, H'. whitteni sp. nov., from North Island, New Zealand, is found to belong to the same clade, despite being placed conventionally in a different family (Hastingsiidae) from both Diaperoecia (Diaperoeciidae) and Heteropora (Cerioporidae). These results challenge the utility of adult skeletal morphology in cyclostome taxonomy. In contrast to the striking dissimilarity between the adult skeletons of D. purpurascens and Hastingsia' whitteni compared with New Zealand species of Heteropora, morphological similarities in early colony development, as well as possibly the presence of a gizzard, corroborate the molecular interpretation of their close relationships. Greater attention should be paid in the future to early astogenetic characters in cyclostome taxonomy.http://zoobank.org/urn:lsid:zoobank.org:pub:CE81CE34-DE0F-43B6-A46E-E086F3F5E76D

Neozelanica（母程），这是一个非常的不同的成人骨骼，传统上置于亚达尔凯里多纳。一种类似于南极属的新物种hastingsia，h'。 Whitteni sp。 11月，来自新西兰北岛，发现属于同一思工，尽管在不同的家庭（牡蛎）和杂蹄虫（Cerioporidae）中常规地放在不同的家庭（Hastingsiidae）中。这些结果挑战了旋转阵列分类中成人骨骼形态的效用。与D. Purpurascens和Hastingsia的成年骨架之间的醒目不同的差异相比，与新西兰的杂孔，在早期殖民地发展中的形态相似性，以及可能存在眩晕的情况下，证实了他们关闭的分子解释关系。将来，将来应更加注重睫状响的仙鱼队的早期大量特征.Http：//zoobank.org/urn：LSID：Zoobank.org：PUB：CE81CE34-DE0F-43B6-A46E-E086F3F5E76D
