Scientific interest has grown over recent years in response to greatly increased perception of the phylogenetic diversity within the conifers as a whole. Much of this has been stimulated by perspectives of increased knowledge of depths of divisions amongst the many living member groupings, especially from DNA-molecular analyses. Interest includes increasing awareness of just how different and ancient have various of the coniferous divisions been, leading to long phylogenetic-autonomy for many components in major evolutionary developments, often with strong independencies across both Hemispheres. The mainly Southern Hemisphere podocarp members are emerging as one of the most diverse of overall arborescent gymnosperm groupings, and this diversity has been one which has spawned increasing interest in matching taxonomic status to phylogenetic perspectives emerging. Amongst these, the early phylogenetic divergences within the Sundacarpus-Prumnopitys alliance have become increasingly apparent. When combined with independent data from several other lines of evidence, a need for re-evaluation of the generic-boundaries within this group becomes necessary. A taxonomic revision is thus proposed here, separating a newly-named segregate genus, Pectinopitys, from the wider Prumnopitys s.l. alliance, as currently known. Consequent nomenclatural changes are given, and impact one of the species in New Zealand (where two genera here recognised are sympatric), plus those of the Australian region and several of those of the South American continent. Two fossil members from the Northern Hemisphere are also taken into account. On the above bases, main morphological features distinguishing Pectinopitys from Prumnopitys s.s. thus especially include, as ‘key’ main identity features, vegetative characters of leaf-type, spacing, insertion and arrangement.

近年来，随着人们对整个针叶树内的系统发生多样性的认识大大提高，对科学的兴趣日益增长。越来越多的观点被许多生物成员尤其是DNA分子分析中的分裂深度的了解所激发。兴趣包括提高人们对各种针叶林划分的区别和古老程度的认识，从而导致主要进化发展中许多组成部分具有长期的系统发育自主性，而这两个半球通常具有很强的独立性。南半球罗汉果的主要成员正在发展成为整个树状裸子植物种类最多样化的群体之一，这种多样性已经引起人们对将分类学地位与新兴的系统发育观点相匹配的兴趣。其中，早期的系统发育差异。桑达卡普斯-仁慈联盟日益明显。当与来自其他几条证据的独立数据相结合时，有必要重新评估该组内的泛型边界。因此，在此提出分类学修订，将新命名的分离属Pectinopitys与更广泛的Prumnopitys sl联盟分离开，这是目前已知的。随之而来的是命名上的变化，并影响了新西兰的一个物种（这里公认的两个属是同属的），以及澳大利亚地区的物种和南美大陆的一些物种。还考虑了北半球的两个化石成员。在上述基础上，主要形态特征得以区分因此，来自Prumnopitys s的果蝇特别包括叶型，间隔，插入和排列的营养特征作为“主要”主要特征。
