Mesechthistatus is a genus of longhorn beetles of the subfamily Lamiinae. Mesechthistatus have atrophied hindwings and are thereby flightless.
Species There are four widely recognized species that all occur in Japan: Mesechthistatus binodosus (Waterhouse, 1881) Mesechthistatus fujisanus Hayashi, 1957 Mesechthistatus furciferus (Bates, 1884) Mesechthistatus taniguchii (Seki, 1944)
Mesechthistatus taniguchii is also known from China. A fifth species, Mesechthistatus yamahoi had not been recorded since the initial description of a specimen from Taiwan and its status as a species was deemed questionable by Nakamine & Takeda in 2008; however, it is treated as valid by the Catalogue of Life in Taiwan that also includes a modern photograph. Yet other sources place this species in its own monotypic genus, Mimechthistatus.
