Three new synonyms of the genus Kamimuria (Plecoptera, Perlidae)

However, the original illustrations of Kamimuria magnimacula Du, 2005 and K. extremispina Du, 2006, lack the necessary detail to accurately assess the spine patterns on the endophallus, which is a key diagnostic feature. To resolve this issue, a re-examination of the type materials, complemented by high-resolution colour photographs, is crucial to ensure precise identification and reliable documentation of these species.Based on a detailed examination of the type materials of Kamimuria magnimacula Du, 2005 and K. extremispina Du, 2006, we propose that K. hunanensis Li & Li, 2022 be considered a synonym of K. magnimacula, K. circumspina Li, Mo & Yang, 2019 and K. dabieshana Yan, Kong & Li, 2021 be regarded as synonyms of K. extremispina.

Additionally, we have provided holotype photographs of K. magnimacula and K. extremispina, along with a distribution map for both species in this paper.
