description: 3.1 The koreana- subgroup
Diagnosis. Species of koreana- subgroup have body mostly black, without metallic tinged macula. The subgroup is characterized by the antennomeres and hind femur entirely black, hind tibia more or less with reddish maculae, posterior corner of metepimeron without distinct appendage.
The koreana- subgroup contains 7 species: M. kongosana Takeuchi (North Korea), M. koreana Takeuchi (Russia, North Korea, China), M. fulvostigmata Wei & Chen (China), M. minutiluna Wei & Chen (China), M. zhongi Wei & Chen (China), M. dabieshanica Wei & Xu (China) and M. liui Wei & Li (China) (Takeuchi, 1937; Wei & Chen, 2002; Wei et al., 2013). Two species are reported as new to science here, namely M. cheni sp. nov. and M. yichangensis sp. nov.
