Abstract

A new oribatid mite genus, Hogsbackia gen. nov. (Oribatida, Punctoribatidae), with type species Hogsbackia africaensis sp. nov., is proposed and described from the indigenous Afromontane forest of South Africa. The new genus is closely related to Scotiazetes, from which it is most easily distinguished by body size ratio, number of notogastral and genital setae, type of humeral porose area Ah, position of dorsophragmata, and leg setation. The redescription of Scotiazetes bidens Wallwork, 1966 is presented, based on material from South Georgia (Antarctic region). The generic diagnosis of Scotiazetes is revised, and the genus is transferred from Ceratozetidae to Punctoribatidae. Relationships between the genera Hogsbackia gen. nov., Scotiazetes and other punctoribatid genera are discussed.

摘要

一个新的食木螨属，Hogsbackia 属。nov.（Oribatida，Punctoribatidae），以南非本土的 Afromontane 森林为栖息地，其模式种为 Hogsbackia africaensis sp. nov.，被提议并描述。新属与 Scotiazetes 密切相关，两者最容易通过身体大小比、背板和生殖器刚毛的数量、Ah 肩区的多孔区类型、背隔的位置以及足的形态来区分。本文根据来自南乔治亚岛（南极地区）的标本，重新描述了 Scotiazetes bidens Wallwork，1966。对 Scotiazetes 的属级诊断进行了修订，并将该属从 Ceratozetidae 转移到 Punctoribatidae。讨论了 Hogsbackia gen. nov.、Scotiazetes 和其他食木螨属之间的关系。
