Abstract
Eremochaetidae is a rare family found from the Late Jurassic to the Early Cretaceous. So far, only 8 genera with 12 species have been recorded. Herein, we describe a new species, Dissup clausus sp. nov., and the first male of Eremomukha (E.) tsokotukha Mostovski, 1996, from the Yixian Formation, the Early Cretaceous of Northeastern China. Additionally, E. (E.) insidiosa Mostovski, 1996 is considered as a new synonym of E. (E.) tsokotukha. An updated list of all known Eremochaetidae is presented.
