在美国东部,已描述了两个属的74种Anillini,大部分属于AnillinusCasey.直到现在,这个大属还没有系统的框架,阻碍综合研究。使用101种近地物种的DNA序列,我们提出了一个解决良好的分子系统发育支持一个健全的系统框架。诊断出16种阿巴拉契亚Anillinus,部分使用了新发现的修饰的雄性原丝数量和精管状态的变化。我们介绍了Nearcticanilline幼虫的第一个描述,不具有先前描述的茴香幼虫的突触。在Anillinus内,两个主要的进化枝大多与右paramere的设置一致:一个“毛茸茸的进化枝”有四个以上的刚毛,还有一个四足进化枝。“在整个系统发育过程中,每个进化枝的微生境使用各不相同,和几个内生谱系是系统发育分离的。我们的工作使南卡罗来纳州的动物群增加了近五倍。描述了九个新物种,Serranillusmonadnocksp.11月。,Anillinuscastaneussp.11月。,Anillinuschoestoeasp.11月。,Anillinusdentatussp.11月。,Anillinusjancaesp.11月。,Anillinusmicasp.11月。,Anillinusmicamicussp.11月。,Anillinussenecasp.11月。,和Anillinussimplexsp.11月。南卡罗来纳州新报道了几种物种,使总数达到20个描述的物种,代表七个物种组。皮埃蒙特的两个特有群体居住在深层粘土中,具有独特的男性性特征。Anillini是近地生物多样性的独特组成部分,作为生物地理学研究的模型系统具有巨大的潜力,次要男性性修饰,和内在的适应。
In the eastern United States, 74 species of Anillini in two genera have been described, with most belonging to Anillinus Casey. Until now, no systematic framework has existed for this large genus, hampering integrative studies. Using DNA sequences from 101 Nearctic species, we present a well-resolved molecular phylogeny supporting a sound systematic framework. Sixteen species groups of Appalachian Anillinus are diagnosed, in part using newly recognized variation in the number of modified male protarsi and the state of the spermathecal duct. We present the first descriptions of Nearctic anilline larvae, which possess none of the synapomorphies of previously described anilline larvae. Within Anillinus, two major clades are mostly consistent with setation of the right paramere: a \"hairy clade\" with more than four setae, and a \"quadrisetose clade.\" Throughout the phylogeny, microhabitat use varies within each clade, and several endogean lineages are phylogenetically isolated. Our work increases the South Carolina fauna by nearly five-fold. Nine new species are described, Serranillusmonadnock sp. nov., Anillinuscastaneus sp. nov., Anillinuschoestoea sp. nov., Anillinusdentatus sp. nov., Anillinusjancae sp. nov., Anillinusmica sp. nov., Anillinusmicamicus sp. nov., Anillinusseneca sp. nov., and Anillinussimplex sp. nov. Several species are newly reported from South Carolina, bringing the total to 20 described species representing seven species groups. Two endemic groups inhabit deep clay soils in the Piedmont and possess unique male sexual characters. The Anillini are a unique component of Nearctic biodiversity, with great potential as a model system for studies of biogeography, secondary male sexual modification, and endogean adaptations.
