Taeniochauliodes是南非最常见和分布最广的鱼蝇属，其中一个历史上公认的有效物种Taeniochauliodes ochracepennis Esben-Petersen。本文对带齿绦虫属Taeniochauliodes进行系统的订正，发现该属至少有8个种：带齿绦虫T. angustus sp.n.，T.渐狭菌属，T. Barnardi sp.n.，T. fuscus sp.n.，T. minutus sp.n.，和T.纳塔尔虫对所有新种进行了描述，并对T.埃斯本彼得塞尼公司& stat.rev.和T.赭色Opennis被制造出来。这些物种都有相对狭窄的分布范围。Taeniochauliodes的种间亲缘关系估计的基础上成人形态数据。根据系统发育结果和目前各种的分布，讨论了该属的历史地理，认为Taeniochauliodes的起源可能可以追溯到晚白垩世。最早的分支，它将T.纳塔尔虫从其余的南非物种，表明一个早期的vicariance事件发生在夸祖鲁-纳塔尔和南非西部地区。此外，Taeniochauliodes内的物种被假设为与其森林栖息地在上新世更新世的碎片。
Taeniochauliodes is the most common and widely distributed fishfly genus in South Africa, with one historically recognized valid species Taeniochauliodes ochraceopennis Esben-Petersen. The present systematic revision of Taeniochauliodes has found that this genus consists of at least eight species: T. angustus sp.n., T. attenuatus sp.n., T. barnardi sp.n., T. fuscus sp.n., T. minutus sp.n., and T. natalensis sp.n. Description of all new species and a redescription of T. esbenpeterseni comb.n. & stat.rev. and T. ochraceopennis are made. These species all have relatively narrowly confined distributions. An interspecific phylogeny of Taeniochauliodes is estimated based on adult morphological data. The historical biogeography of this genus is discussed based on the phylogenetic results and the present distribution of each species, suggesting that the origin of Taeniochauliodes likely dates back to the Late Cretaceous. The earliest branch, which separates T. natalensis sp.n. from the remaining South African species, suggests an early vicariance event occurred between KwaZulu-Natal and more western parts of South Africa. Furthermore, speciation within Taeniochauliodes is hypothesized to be correlated with fragmentation of its forest habitat during the Plio-Pleistocene.
