REMARKS

This species was described from the holotype male and several paratypes (male and female) from Kyushu ( Japan) and two female paratypes from Hong Kong. Although no depository for the types is indicated in the original description, it states in the acknowledgements to the paper that the type series was borrowed from EIHU, and this is presumed to be Matsumura’s collection. Therefore, Matsumura’s misidentification given in the original description (see above) refers to Matsumura (1934) where Empoasca rufa Melichar is listed from Japan and not (as stated) Matsumura (1931) where it is listed from Formosa. The female paratypes from Hong Kong could equally be D. formosus examined here from a male from Hong Kong and hence the question mark under Distribution. The colour of D. takagii was not originally described except that the species resembled D. euryphaessus but with paler coloration. The female tentatively identified here as this species (based on its locality Japan), is mainly reddish in colour.
