Six new species of the Spirobolida millipede genus Riotintobolus Wesener, 2009, are described from the spiny forest in southern Madagascar utilising genetic barcoding, drawings and scanning electron microscopy: Riotintobolus tsimelahysp. nov., R. mangatsiakasp. nov., R. lavanonosp. nov., R. bovinussp. nov., R. antafokysp. nov. and R. makayisp. nov. One other Riotintobolus population from the spiny forest might represent an additional species based on genetic data, but it cannot be described as no male specimens were collected. At present, the genus Riotintobolus Wesener, 2009 has eight species from the spiny forest and two species from the littoral rainforest. A determination key to all ten species of the genus is provided. Molecular data reveal that the two critically endangered species from the humid littoral rainforest are not closely related to one another, but have their closest relative in the dry spiny forest ecosystem. Riotintobolus mandenensis Wesener, 2009, only known from the southern littoral rainforest of Mandena is related to R. tsimelahysp. nov. from the nearby spiny forest at Tsimelahy with a p-distance of 11%, while R. minutus Wesener, 2009 from the littoral forest of Sainte Luce is more distant to all other Riotintobolus species, but more closely related to R. bovinussp. nov. from the southwestern forest of the Makay.

马达加斯加南部的过渡带转移:第一个条形码数据和六个特有的千足虫属Riotintobolus(螺螺旋体,Pachybolidae)的六个新物种。

利用遗传条形码,绘图和扫描电子显微镜从马达加斯加南部的多刺林中描述了六种螺旋形千足虫属Riotintobolus Wesener,2009年:Riotintobolus tsimelahysp。11月,R。mangatsiakasp。十一月,R。lavanonosp。11月,R。bovinussp。11月,R。antafokysp。十一月 和R. makayisp。十一月 基于遗传数据,来自多刺森林的另外一个Riotintobolus种群可能代表了另外一个物种,但由于没有收集到任何男性标本,因此无法描述。目前,2009年的Riotintobolus Wesener属有八种来自多刺森林,两种来自沿海雨林。提供了该属的所有十个种类的确定键。分子数据显示,来自潮湿的沿海雨林的两个极度濒危物种彼此之间并不密切相关,但在干燥的多刺森林生态系统中具有最接近的亲缘关系。Riotintobolus mandenensis Wesener,2009年,仅从南部的曼德纳沿海雨林中得知,与R. tsimelahysp有关。十一月 R. minutus Wesener,2009年来自圣卢斯沿海森林,距附近的Tsimelahy的多刺林距离大约为11%,R。minutus Wesener,2009年与所有其他Riotintobolus物种距离较远,但与R. bovinussp关系更密切。十一月 来自马凯的西南森林。R. minutus Wesener,2009年来自圣卢斯沿海森林,距附近的Tsimelahy多刺林距离约11%,而R. minutus Wesener,2009年距所有其他Riotintobolus物种较远,但与R. bovinussp息息相关。十一月 来自马凯的西南森林。R. minutus Wesener,2009年来自圣卢斯沿海森林,距附近的Tsimelahy多刺林距离约11%,而R. minutus Wesener,2009年距所有其他Riotintobolus物种较远,但与R. bovinussp息息相关。十一月 来自马凯的西南森林。
