Purpose

Euschoengastia Ewing is a chigger genus in need of revision as it historically has combined species solely on the presence of expanded prodorsal trichobothria. The objective of the present study is to describe a new genus to reallocate two North American Euschoengastia species, to start an organization into this genus.

Methods

In this study, we provide drawings, measurements and microscopy images on a Microscope Zeiss for the two redescribed species.

Results

After examining the types of the species Euschoengastia latchmani Brennan and Yunker and Euschoengastia obscura Wrenn and Loomis, we realized that it was necessary to create the new genus to relocate these two species, mainly based on the following characters: (1) the number of prongs on the odontus; and (2) ornamentation of the prodorsal sclerite.

Conclusion

Goffacarus latchmani n. comb. and Goffacarus obscura n. comb. are redescribed here and to reallocate these two species the genus, Goffacarus n. gen. is proposed.

Goffacarus n. 的描述。gen., 重新分配物种 Euschoengastia latchmani Brennan 和 Yunker 以及 Euschoengastia obscura Wrenn 和 Loomis（Trombidiformes：Trombiculidae）

目的

Euschoengastia Ewing 是一个需要修改的恙螨属，因为它在历史上仅根据扩大的前背毛癣菌的存在来合并物种。本研究的目的是描述一个新属，以重新分配两个北美Euschoengastia物种，以在该属中建立一个组织。

方法

在这项研究中，我们在蔡司显微镜上提供了两种重新描述的物种的图纸、测量值和显微镜图像。

结果

在考察了Euschoengastia latchmani Brennan 和 Yunker 以及Euschoengastia obscura Wrenn 和 Loomis的种类后，我们意识到有必要创建新属来重新定位这两个物种，主要基于以下几个特征：（1）齿数在 odontus 上；(2) 前背骨的纹饰。

结论

Goffacarus Latchmani n. 梳子。和Goffacarus obscura n. 梳子。在这里重新描述并重新分配这两个物种的属，Goffacarus n。将军 被提议。
