Recent expeditions in Kenya and examination of existing collections confirmed the presence of two undescribed Chiloglanis species and revealed previously unknown diversity within the Athi River system. The two new species are easily distinguished from described congeners in the area by external morphology, allopatric distributions, and genetic markers. Chiloglanis kerioensis sp. nov., is restricted to the Kerio River system and is the only known suckermouth catfish from the Lake Turkana basin. Chiloglanis devosi sp. nov., is known only from the type locality, the Northern Ewaso Nyiro (Ng'iro) below Chanler's Falls. In addition to these two new species, this study confirmed the presence of an undescribed Chiloglanis sp. occurring sympatrically with Chiloglanis brevibarbis in the Tsavo River. A dichotomous key for identifying all described Chiloglanis species found within Kenya is presented along with comments.
近期在肯尼亚的考察以及对现有标本的研究证实,存在两种未被描述过的唇吸鳅属物种,并揭示了阿西河水系内此前未知的生物多样性。这两个新物种通过外部形态、异域分布和遗传标记,很容易与该地区已描述的同属物种区分开来。新物种凯里唇吸鳅(Chiloglanis kerioensis sp. nov.)仅分布于凯里河水系,是图尔卡纳湖盆地已知的唯一一种吸口鲶鱼。新物种德沃西唇吸鳅(Chiloglanis devosi sp. nov.)仅在其模式产地被发现,即位于钱勒瀑布下游的北埃瓦索恩吉罗河(Ng'iro)。除了这两个新物种,本研究还证实,在察沃河有一种未被描述的唇吸鳅属物种与短须唇吸鳅(Chiloglanis brevibarbis)同域分布。文中还给出了一个用于鉴别在肯尼亚发现的所有已描述唇吸鳅属物种的二分检索表及相关注释。
