Abstract

While new species of termites are described every year, the description of species distant from every known termite species is rare. In this paper, we describe one such species, Engelitermes zambo sp.n., an African Termitidae belonging to an entirely new lineage of termites for which we create a new subfamily, Engelitermitinae subfam.n. The subfamily status of Engelitermitinae was supported by termite phylogenetic trees, including sequences from the four existing samples of E. zambo sp.n., which, albeit with low bootstrap supports, placed Engelitermes gen.n. on a long branch sister to Forficulitermes, the two of which formed the sister group of a clade comprising Cubitermitinae, Nasutitermitinae, Syntermitinae and all other Termitinae. The sister relationship between Engelitermes gen.n. and Forficulitermes is further supported by the similar gut structure of their workers. In contrast, the soldiers of Engelitermes gen.n. resemble those of Cephalotermes. Our phylogenetic analyses, including all clades of Termitinae, call for a global taxonomic revision of the Termitinae subfamily names. Finally, our study highlights that new unique termite lineages are still awaiting to be described.

线粒体系统发育学将一种新的非洲白蚁物种定位到自己的亚科Engelitermitinae中(Blattodea:白蚁科)
虽然每年都有新的白蚁物种被描述,但与每一种已知白蚁物种相距甚远的物种描述却很少见。在本文中,我们描述了一个这样的物种,Engelitermes zambo sp.n,这是一个非洲白蚁科,属于一个全新的白蚁谱系,我们为其创建了一个新的亚科,Engelitelitinae亚科。Engelitelmininae的亚科地位得到了白蚁系统发育树的支持,包括来自E.zambo sp.n的四个现有样本的序列,尽管具有较低的自举支持,但将Engelitermes gen.n.放在Forficulitermes的一个长分支姐妹上,这两个分支形成了一个分支的姐妹群,该分支包括Cubitermitinae、Nasutitermtinae、Syntermtinae和所有其他Termitinae。Engelitermes gen.n.和Forficulitermes之间的姐妹关系进一步得到了其工人相似肠道结构的支持。相比之下,Engelitermes gen.的士兵与Cephalotermes的士兵相似。我们的系统发育分析,包括白蚁亚科的所有分支,呼吁对白蚁亚科名称进行全球分类修订。最后,我们的研究强调,新的独特白蚁谱系仍有待描述。
