We describe a new record genus Munamizoa,Matsushita et Tamanuki,1940,and a new species,Munamizoa changbaishanensis sp. nov.,from China. Type specimens are deposited in the Insect Collection,Forestry College of Beihua University,Jilin,China. Munamizoa changbaishanensis sp. nov. （Figs 1-9） Male. Body length 12.2-14.1 mm,width 3.3-3.8 mm. Head and pronotum black with gray tomenta; elytra black-brown,with dense brown tomenta and brown stripe that varied greatly,i.e.,each humeral angle of elytra with a little upright speckle,base of elytra behind the elytra with a great upright speckle,the central outside of elytra with a oblique stripe and with a reversed ＂J＂ stripe inside （Figs 1-2）; the elytra shoulder with a flyspeck,and base of the elytra behind scutellum with a great speckle,in the middle of elytra,two speckles cicatrize a reversed ＂C＂ stripe （Fig. 3）; or the elytra shoulder with a flyspeck unchanged,base of elytra behind scutellum,the upright speckle＇s back edge with two speckles in the middle of the elytra cicatrize a reversed ＂3＂ stripe （Fig. 4）. Antenna slightly shorter than body,scape wide and equal to the forth,the second segment shortest,the third segment longer than the forth one but shorter than the fifth one. Pronotum with dense wide puncta,and narrow base and wide end,an conspicuously central longitudinal furrow extending its end,and diverging,and showing inverse ＂V＂ with two sides ridgy. The end of elytra smooth or little smooth. The end of femora intumescent,the first tarsus of hind legs longer than the others. Male genitalia （Figs 5-9）. Paramere cylindrical,the inner margin lightly concave with 3 to 6 bristles on it,its segmental venter with sparse and short bristles,a pair of approximately triangular chitin films at the base; no roof; the cardo long and thin,the median entad curving,the end united; median struts and median struts lobe strongly curving,median struts wide and united in the end; the internal sac thick and long,from the 1/4 base to 3/4 terminal part with ossificated thorns at its basal section. Host. Unknown. Visiting Plant. Aruncus sylvester Kostel. ex Maxim. Etymology. The new species was named after the site where the type specimens were collected. Munamizoa changbaishanensis sp. nov. is very similar to the type species of the to Munamizoa maculate （Matsushita et Tamanuki,1935）,but differs from the latter in having male antenna shorter than elytra,two to four irregularly yellow-brown on each elytra,and the first tarsus of its hind leg longer than the length of all the other tarsus.
