Janus rnegarnaculatus Liu ＆ Wei sp. nov. and J. rufus Liu ＆ Wei sp. nov. are described from China. Janus megamaculatus sp. nov. differs from its known congeners by the body very large, head and thorax yellow brown with few black macula, the abdomen yellow brown with transverse black bands, the mesoscutal middle lobe with a deep middle furrow and the apical sheath as long as the basal sheath. Janus rufus sp. nov. is similar to Janus xanthus Naito ＆ Smith, 1998 in structure but differs from the latter by the head and thorax almost entirely yellow brown, the antenna brown and about 2 times as long as head and thorax together, the hind femur yellow brown, the cell Rs in hindwing closed and cereus 0.14 times as long as the apical sheath.展开更多
