在新西兰北部和塔斯马尼亚东北部浅水区发现了两种小型且非常独特的藤壶，这为重新评估现存胸甲动物中最原始的藤壶科提供了一个机会。它们保留在胸总目中，但在序数水平上与有梗总目 s.l. 的其余部分区分开来。由此产生的新目，Ibliformes nov.，由藤壶组成，其主要是几丁质而不是钙质的头状体板；两个科被认可，Iblidae s.s.，包括两个亚科，Iblinae (Ibla s.s.) 和 Neoiblinae nov.。 （Neoibla gen. nov.）和 Idioiblidae nov.包括 Idioiblinae nov. （Idioibla gen. nov.）和 Chaetolepadinae nov. （Chaetolepas Studer，1889 年和 Chitinolepas gen. nov.）。单型几丁鱼进一步凸显了新西兰海洋动物群和整个南半球的高度特有性和孑遗性质。根据形态学以及遗传和幼虫研究（如果可能），建议将其余的有柄胸甲动物分为三个新目：†Cyprilepadiformes、Ibliformes、Lepadiformes 和 Scalpelliformes。
The discovery of two diminutive and very distinct ibliform barnacles from shallow waters off northern New Zealand and northeastern Tasmania provides an opportunity to re-evaluate the Iblidae, the most primitive of the living thoracicans. These are retained within the Superorder Thoracica, but are distinguished at ordinal level from the remainder of the Pedunculata s.l. The resultant new order, the Ibliformes nov., comprises barnacles with predominantly chitinous rather than calcareous capitular plates; two families are recognized, the Iblidae s.s., comprising two subfamilies, the Iblinae (Ibla s.s.) and the Neoiblinae nov. (Neoibla gen. nov.), and the Idioiblidae nov. comprising the Idioiblinae nov. (Idioibla gen. nov.) and the Chaetolepadinae nov. (Chaetolepas Studer, 1889 and Chitinolepas gen. nov.). The monotypic Chitinolepas further highlights the high endemism and relict nature of the New Zealand marine fauna in particular and the southern hemisphere in general. On the basis of morphology and, where possible, genetic and larval work, it is recommended that the remainder of the stalked thoracicans be divided between three new orders, the †Cyprilepadiformes, Ibliformes, Lepadiformes and Scalpelliformes.
