报道了在东南极洲广泛分布的一批食草象。成年标本的平均体长从这些地方的一些显着不同，从其他地方和不同的栖息地类型。在南极螨的其他物种中没有发现这里报道的大小的地理变化，并讨论了可能的原因。本文还描述了标本间的其它形态变异，并简要记录了T.在韦斯特福尔山的erebus介绍。本文对三种不同形态的瓦氏树蛙Tydeus wilkesi Strandt mannar与T. erebus Strandtmann和被认为是属于后者的物种。
A collection of Tydeus erebits Strandtmann from widespread localities in East Antarctica is reported. The mean body lengths of adult specimens from some of these localities differ significantly from those at other localities and vary with the type of habitat. Geographic variation in size of the magnitude reported here has not been found in other species of Antarctic mites, and possible causes are discussed. Other morphological variation between the specimens is described and brief notes on the behaviour and reproduction of T. erebus at the Vestfold Hills are presented. Three paratypes of Tydeus wilkesi Strandt mannare compared with specimens of T. erebus Strandtmann and are considered to belong to the latter species.
