在赤道非洲肯尼亚辛巴山自然保护区的9个土壤样本中发现了非常多样化的纤毛虫群落。用不加水的培养皿方法，从风干的样品中分别重新激活纤毛虫，它们的休眠包囊。物种是从生命中确定的，并通过浸银确定。在已鉴定的125个分类群中，有34个(27%)在1985年收集和调查样本时尚未被描述。落叶原始林和幼龄次生松林的样地种类最丰富，各有59种。在辛巴山上发现的最引人注目的物种是Krassniggia Assistant iliaris、Bresslauides terricola、Gigantothrix herzogi和Afothrix darbyshirei。它们是“旗舰”，具有非常独特的形态，由于它们超大的身体尺寸，很容易识别。Krassniggia Assistant iliaris也发生在澳大利亚，可能像其他一些纤毛虫一样，具有有限的冈德瓦南分布。后来在除南极洲以外的所有主要生物地理区的土壤中都发现了白纹藻。巨藻和达比希雷龙虾仍然是辛巴山独有的物种。文中详细描述了它们的分类群：新亚种Sikoropsworonowiczae nov.Gen.，11月Spc.、多核弯孢霉Arcuospardium Multicum nov.Spec.，Dileptus similis Foissner，1995，Plagiocampa bitricha nov.、甜菜单胞菌D erpanomonas exigua Penard，1922，甜菜单胞菌D.exigua bientata nov.Sp.spc.(Penard，1922)nov.Comb.、白粉菌P.terricola nov.、短足类短脚亚种Brachyosoma brachypoda Mallachypoda nov.Spc.、赫氏巨藻Giantothrix herzogi nov.Gen.，11月Spc.、达比雪莲Afothrix darbyshirei nov.Gen.，11月、非洲棘豆Oxytricha africana nov.Spc.和线虫O.elegans nov.规范。
A very diverse ciliate community was found in nine soil samples from the Shimba Hills Nature Reserve in Kenya, equatorial Africa. The ciliates, respectively, their resting cysts, were re-activated from air-dried samples using the non-flooded Petri dish method. Species were determined from life and by silver impregnation. 34 (27%) of the 125 taxa identified had not yet been described in 1985, when the samples were collected and investigated. The richest samples, each containing 59 species, were those from a deciduous primary forest and a young secondary pine forest. The most remarkable species discovered in the Shimba Hills were Krassniggia auxiliaris, Bresslauides terricola, Gigantothrix herzogi, and Afrothrix darbyshirei. They are "flagships" with a very distinct morphology and easy to recognise due to their extraordinarily large body size. Krassniggia auxiliaris occurs also in Australia and probably has a restricted Gondwanan distribution, like some other ciliates. Bresslauides terricola was later found in soils from all main biogeographical regions, except for Antarctica. Gigantothrix herzogi and Afrothrix darbyshirei are still unique to the Shimba Hills. The following taxa are described in detail: Sikorops woronowiczae nov. gen., nov. spec., Arcuospathidium multinucleatum nov. spec., Dileptus similis Foissner, 1995, Plagiocampa bitricha nov. spec., Drepanomonas exigua exigua Penard, 1922, D. exigua bidentata nov. sspec., Parafurgasonia protectissima (Penard, 1922) nov. comb., P. terricola nov. spec., Brachyosoma brachypoda mucosa nov. sspec., Gigantothrix herzogi nov. gen., nov. spec., Afrothrix darbyshirei nov. gen., nov. spec., Oxytricha africana nov. spec., and O. elegans nov. spec.
