Jiangsu: 1♂ ( Fig. 8 ), Jurong, Baohuashan , 9-VII-2014, leg. Jianyue Qiu ( MYNU) .

Distribution. China (Beijing, Jiangsu), S. Korea.

Host plant. Celtis sp. ( Ulmaceae ) (Yamasako & Hasegawa, 2009).

Remarks. This species was previously known only from S. Korea (Yamasako & Hasegawa, 2009). It is recorded from China for the first time (Beijing and Jiangsu), indicating that it has wider distribution.

Yamasako & Hasegawa (2009) compared this species with M. (P.) hirsuta distributed in Japan, Korea and Russian Far East. According to our study, it is also quite similar to M. (P.) atrostigma Gressitt, 1942 by the elytral maculae, especially the middle part. However, it can be easily distinguished from each other by: a) presence ( atrostigma ) or absence ( hyunchaei ) of four black maculae on pronotum; b) absence ( atrostigma ) or presence ( hyunchaei ) of light color pubescent markings at basal part of elytra, around humeri.
