介壳虫（半翅目：胸喙：Coccoidea）是一个物种和形态学上专门化的植物食性昆虫群，其中进化关系和更高的分类是有争议的。来自核小亚基核糖体DNA的序列被用来产生一个初步的分子系统学的椰子总科的基础上代表14个假定的家庭的39种。单系的archaeococcoids（包括Ortheziidae，Margarodidae广义，和Phenacoleachia）是模棱两可的，而单系的neococcoids的支持。以Puto yuccae为代表的Putoidae被发现在新球菌分支的其余部分之外。这些数据是一致的一个单一的起源（在新球菌分支的祖先）的染色体系统，涉及父亲的基因组消除男性。粉蚧科（Pseudocococcusae）似乎是其他新蚧科的姐妹，有迹象表明，粉蚧科（Cococcusae）和蚧科（Kerriidae）是姐妹分类群。绒蚧科（毡鳞）没有恢复为一个单系组和绒蚧属广义绒蚧是多系的。(C)2002 Elsevier Science（美国）。All rights reserved.
Scale insects (Hemiptera: Sternorrhyncha: Coccoidea) are a speciose and morphologically specialized group of plant-feeding bugs in which evolutionary relationships and thus higher classification are controversial. Sequences derived from nuclear small-subunit ribosomal DNA were used to generate a preliminary molecular phylogeny for the Coccoidea based on 39 species representing 14 putative families. Monophyly of the archaeococcoids (comprising Ortheziidae, Margarodidae sensu lato, and Phenacoleachia) was equivocal, whereas monophyly of the neococcoids was supported. Putoidae, represented by Puto yuccae, was found to be outside the remainder of the neococcoid clade. These data are consistent with a single origin (in the ancestor of the neococcoid clade) of a chromosome system involving paternal genome elimination in males. Pseudococcidae (mealybugs) appear to be sister to the rest of the neococcoids and there are indications that Coccidae (soft scales) and Kerriidae (lac scales) are sister taxa. The Eriococcidae (felt scales) was not recovered as a monophyletic group and the eriococcid genus Eriococcus sensu lato was polyphyletic. (C) 2002 Elsevier Science (USA). All rights reserved.
