Abstract

Abstract A new species of herpelid caecilian, Boulengerula endauensis sp. nov. is described from Endau Hill Forest, Kitui County, Kenya. The new species differs from all other Boulengerula species in having tentacles that are positioned equidistant between the corner of the mouth and snout tip. It can also be distinguished by its body colour, which is predominantly brownish pink as compared to the others, the majority of which are bluish to purple. The new species is very similar to B. denhardti in body colour and both species have a high average number (> 160) of body rings (annular grooves). Boulengerula endauensis sp. nov. differs from B. denhardti by having a lower body length to body width ratio and more posteriorly positioned tentacles on the head. Boulengerula denhardti occurs in the Tana River Delta area in Lake Kenyatta forest-Lamu at the coastal strip about 250 kilometres to the south-east from B. endauensis. The discovery of this species, on an isolated arid montane rocky hill, influenced by the Indian Ocean moist winds, may indicate that characteristically similar hills could harbour additional new Boulengerula species.
来自肯尼亚东南部 Endau Hill 的 Boulengerula 属 Caecilian 新物种
摘要 本文描述了产自肯尼亚基图伊县恩道山森林的一种新的硬骨鱼类--Boulengerula endauensis sp.。该新种与其他所有 Boulengerula 种类的不同之处在于其触手位于嘴角与鼻尖之间的等距离位置。它的体色主要为棕粉色,而其他物种的体色大多为蓝色至紫色。新种的体色与 B. denhardti 非常相似,两个物种的体环(环状凹槽)平均数量都很高(大于 160 个)。Boulengerula endauensis sp. nov. 与 B. denhardti 的不同之处在于其体长与体宽的比例较低,头部触手的位置更靠后。Boulengerula denhardti 出现在塔纳河三角洲地区的肯雅塔湖森林-拉穆沿海地带,距离 B. endauensis 东南方约 250 公里。受印度洋潮湿风的影响,在一个孤立的干旱山地岩石山上发现了这一物种,这可能预示着具有类似特征的山地可能蕴藏着更多的 Boulengerula 新物种。
