The African continent has 452 chiggers (Trombidiformes: Trombiculidae) in 61 genera. One of these, Elianella Vercammen-Grandjean, 1956, has only two species known for Africa. The objective of the present study is to describe a new species for Equatorial Guinea, with the aim of increasing knowledge so scarce for Africa.
In this study, we provide drawings, measurements and microscopy images on a Microscope Zeiss for the new species described below. Also, this type of the new species is deposited in the USNM.
We describe a new species of Elianella collected parasitizing the Bioko Forest Shrew, Sylvisorex isabellae Heim de Balsac (Eulipotyphla: Soricidae) from the insular Equatorial Guinea. Also, we are providing a key for the three species of Elianella.
Finally, we are contributing to the knowledge of African species, due the fact this new species is the first chigger recorded to the Equatorial Guinea, on the west coast of Central Africa.
非洲大陆有 452 种恙螨（Trombidiformes：Trombiculidae），分属于 61 个属。其中有一个属名为 Elianella Vercammen-Grandjean, 1956，仅在非洲有两种已知物种。本研究的目的是描述一种新的来自赤道几内亚的物种，旨在增加对非洲如此稀缺的知识的了解。
在这项研究中，我们提供了以下新种的绘图、测量和显微镜图像，这些图像是在 Zeiss 显微镜下获得的。此外，这种新型还被存放在 USNM 中。
我们描述了一种从赤道几内亚岛屿上的 Bioko Forest Shrew, Sylvisorex isabellae Heim de Balsac（Eulipotyphla：Soricidae）身上寄生的 Elianella 新种。此外，我们还提供了 Elianella 属的三种物种的关键特征。
最后，我们为非洲物种的知识做出了贡献，因为这种新物种是赤道几内亚首次记录到的恙螨，位于非洲中部西海岸。
