Mauson, Tonkin (Vietnam), April-Mai, Fruhstorfer, H., no. 1079 (NHMW). = Asceles longzhouensis Chen & He, 2000: 395 [Formerly treated as synonym of Sipyloidea sipylus by Chen & He, 2008: 176]

Notes. This is a new record of species in Hainan. Chen and He (2008: 176) synonymised Asceles longzhouensis Chen & He, 2000 with Sipyloidea sipylus (Westwood, 1859) . In fact, A. longzhouensis is identical to the male Sipyloidea biplagiata Redtenbacher, 1908 and is here removed from synonymy with S. sipylus .
