Remarks. The holotype of Monochamus fruhstorferi Breuning, 1964 was misidentified as a male (Breuning, 1964), but it is a female and it can be easily identified by the darker apices from antennomeres III to XI and the shape of ventrite V. It matches with the holotype female of Urecha (sic) lunulata Pic, 1934 very well and is herein synonymized, although it was identified as Annamanum lunulatum (Pic, 1934) by Carolus Holzschuh in 1996 (Fig. 4c). And the series of specimens collected from Vietnam confirmed that males of this species are identical to the holotype male of Uraecha longzhouensis Wang & Chiang, 2000 from Guangxi, China.
