Abstract

Mesoceration explanatum sp. nov. and M. piketbergense sp. nov. are described from the Piketberg range in the Western Cape Province, South Africa, bringing the total number of known species in the genus to 55, all of which are endemic to South Africa. M. explanatum sp. nov. is a member of the truncatum group, whilst M piketbergense sp. nov. belongs to the endroedyi group and is apparently closely related to M. concessum Perkins Balfour-Browne, 1994 and M. tabulare Perkins, 2008, both of which are endemic to the Cape Peninsula. The two new species were both relatively abundant in the Piketberg, and may be narrowly endemic to this inselberg-like mountain range.

摘要

新种Mesoceration explanatum和新种M. piketbergense是在南非西开普省的皮克泰贝格山脉发现并被描述的，这使得该属已知物种总数达到55种，所有这些物种均为南非特有。新种Mesoceration explanatum属于truncatum组，而新种M piketbergense属于endroedyi组，并且显然与1994年Perkins Balfour - Browne命名的M. concessum以及2008年Perkins命名的M. tabulare关系密切，后两者均为开普半岛特有。这两个新物种在皮克泰贝格都相对丰富，可能是这个类似岛山的山脉所特有的狭域分布物种。
