甲蚁属Prenolepis在这里是第一次被修正。已知现存种13种，其中4种为新种。提供了工人种姓的钥匙，每个物种的工人都被成像，雄性和女王被成像在他们所知的物种中。以工蚁为基础的特征被用来构建Prenolepis的物种水平的系统发育。系统发育分析采用最大简约法和贝叶斯推理法。文中提供了该属的形态诊断，并讨论了可用于区分Prenolepis属群中的Prenolepis属的有用形态特征。提出了主要的分类变化。新种为：P.Darlena、P.fustinoda、P.mediops和P.shanialena。Prenolepis Jerdoni subopaca上升为全种。三个种被排除在Prenolepis中，并作为新组合转移到Nylanderia和ParatreChina：N.Emmae，N.flaviabdomis和P.umbra。两个种被排除在副中国之外，并作为新组合转移到尼兰德拉和副中国：观音和孔明。一种，Z.darlingtoni，被排除在Nylanderia中，并作为一个新的组合转移到Zatania。提出了几个异名：Prenolepis sphingthoraxa=Nylanderia flaviabmunis，P.imparis arizonica，P.imparis colimana，P.imparis Colimana，P.imparis veracruzsis=P.imparis，P.Blackogaster carinifrons and P.nigriflagella=P.Blackogaster，P.long giventris和P.magnocula=P.Naoroji，以及P.Septemdenta=Nylanderia opisopeyia。
The formicine ant genus Prenolepis is here revised for the first time. Thirteen extant species are recognized of which four are described as new. A key for the worker caste is provided, and the worker of each species is imaged, with males and queens imaged in species where they are known. Worker-based characters were used to construct a species-level phylogeny of Prenolepis. Both maximum parsimony and Bayesian inference methods were used for the phylogenetic analyses. A morphological diagnosis for the genus is provided, with a discussion of useful morphological characters for separating Prenolepis from other genera in the Prenolepis genus-group. Major taxonomic changes are proposed. The new species are: P. darlena, P. fustinoda, P. mediops, and P. shanialena. Prenolepis jerdoni subopaca is elevated to full species. Three species are excluded from Prenolepis and transferred to Nylanderia and Paratrechina as new combinations: N. emmae, N. flaviabdominis, and P. umbra. Two species are excluded from Paratrechina and transferred to Nylanderia and Paraparatrechina as new combinations: N. guanyin and P. kongming. One species, Z. darlingtoni, is excluded from Nylanderia and transferred to Zatania as a new combination. Several synonyms are proposed: Prenolepis sphingthoraxa = Nylanderia flaviabdominis; P. imparis arizonica, P. imparis colimana, P. imparis coloradensis, and P. imparis veracruzensis = P. imparis; P. melanogaster carinifrons and P. nigriflagella = P. melanogaster; P. longiventris and P. magnocula = P. naoroji; and P. septemdenta = Nylanderia opisopthalmia.
