我们研究了Prenolepis属群的系统发育和分类，Prenolepis属群是我们在蚁科中定义的一个蚂蚁分支，包括Euprenolepis属、Nylanderia属、gen. rev.副帕拉特雷中国，总修订与统计。十一月，Paratrechina，Prenolepis和Pseudolasius。我们从50个分类群中提取的5个基因（CAD、EF 1 α F1、EF 1 α F2、wingless和COI）的DNA序列数据推断了Prenolepis属群的进化。在此基础上，重新对该属的分类进行了研究。Paratrechina（广义）种分成三个不同的，粗壮的分支。Paratrechina longicornis代表了一个独特的谱系，与形态学证据相一致的结果;因为这是该属的模式种，Paratrechina被重新定义为单型属。两个以前合群化的亚属，Nylanderia和Paraparatrechina，被提升为属的地位，以便为其他两个分支提供名称。大部分的分类群以前放置在Paratrechina，133种和亚种，被转移到Nylanderia，28种和亚种转移到Paraparatrechina。另外，有两种拟棘球绦虫被转移到副棘球绦虫中，一种拟棘球绦虫被转移到尼兰德氏绦虫中。所有六个属的工人种姓的形态诊断提供，与用于定义每个属的形态特征的讨论。两个属，Prenolepis和Pseudolasius，没有恢复为单系的分子数据，这一结果的影响进行了讨论。编制了一个以工蜂为基础的单鳞属属组各属检索表。
We investigated the phylogeny and taxonomy of the Prenolepis genus-group, a clade of ants we define within the subfamily Formicinae comprising the genera Euprenolepis, Nylanderia, gen. rev., Paraparatrechina, gen. rev. & stat. nov., Paratrechina, Prenolepis and Pseudolasius. We inferred a phylogeny of the Prenolepis genus-group using DNA sequence data from five genes (CAD, EF1 alpha F1, EF1 alpha F2, wingless and COI) sampled from 50 taxa. Based on the results of this phylogeny the taxonomy of the Prenolepis genus-group was re-examined. Paratrechina (broad sense) species segregated into three distinct, robust clades. Paratrechina longicornis represents a distinct lineage, a result consistent with morphological evidence; because this is the type species for the genus, Paratrechina is redefined as a monotypic genus. Two formerly synonymized subgenera, Nylanderia and Paraparatrechina, are raised to generic status in order to provide names for the other two clades. The majority of taxa formerly placed in Paratrechina, 133 species and subspecies, are transferred to Nylanderia, and 28 species and subspecies are transferred to Paraparatrechina. In addition, two species are transferred from Pseudolasius to Paraparatrechina and one species of Pseudolasius is transferred to Nylanderia. A morphological diagnosis for the worker caste of all six genera is provided, with a discussion of the morphological characters used to define each genus. Two genera, Prenolepis and Pseudolasius, were not recovered as monophyletic by the molecular data, and the implications of this result are discussed. A worker-based key to the genera of the Prenolepis genus-group is provided.
