Abstract
The spider genus Khorata Huber, 2005 is a diverse group distributed in the Indo-Malayan Region. In this study, we describe two new species from southern China: Khorata nani sp. nov. (male, female; Guangdong) and Khorata yuhaoi sp. nov. (male, female; Yunnan and Guizhou). In addition, we briefly discuss the potential causes of its diversity.
