The genus Macrispa Baly, 1859, previously known only from Southeast Asia and south of the Himalayas, has remained unrecorded in China until now. Here, we report the first discovery of Macrispa saundersii Baly, 1859 from Xizang Autonomous Region, China, representing a northward range extension for the genus. Through integrative examination of external morphology and male genitalia, we provide a comprehensive redescription of M. saundersii. High-resolution stacked imaging was employed to document key taxonomic characters, including elytral punctation patterns, stridulatory files, abdominal ventrite structures, and male genitalia.
