FULGORIDAE : Zanna dohrni (Stål) ( SRI LANKA ); Lycorma delicatula (White) ( CHINA ). Remarks. Descriptions of the morphological characters of D . browni and D. santoni Ashmead seem very similar to each other. Olmi (1997) proposed D. lycormae Yang as a junior synonym of D. santoni . In contrast, He & Xu (2002) proposed D. lycormae as a junior synonym of D. browni . In both cases, the type locality of each species is Oriental, but only adults reared from L. delicatula were collected from Palaearctic China . The author treats the dryinid species from Palaearctic Japan as D. browni because the specimen has an important specific character status, the flattened antennae. However, further study is needed to settle this problem. L. delicatula is included in the fauna of Japanese insects (Hirashima, 1989), although its distributional record from Japan is doubtful (Kamitani, personal communication). As a Japanese population, D. browni is distributed in both the Palaearctic and Oriental regions of Japan . Specimens collected from Ishigaki-jima differ from other specimens in the following two characters: the testaceous margin of the pronotum and the smooth median part of the scutum.
