description: 3.2 The sanguinolenta- subgroup
Diagnosis. The sanguinolenta- subgroup usually has body mostly black, without metallic tinged macula and antenna entirely black. It is characterized by hind femur and tibia more or less with reddish maculae, posterior corner of metepimeron without distinct appendage.
Thirteen species of sanguinolenta- subgroup is known from China: M. sanguinolenta Gmelin (Europe, Turkey, Mongolia, Japan, North Korea, China), M. erythrocnema A. Costa (Europe, Turkey, Caucasia, China), M. canescens Mallach (China), M. rufoclypeata Wei (China), M. leucotarsalina Wei & Chen (China), M. pentanalia Wei & Chen (China), M. erythrocephalica Wei & Nie (China), M. maculotarsalina Wei & Liu (China), M. shennongjiana Wei & Zhao (China), M. jiangi Zhao & Wei (China), M. yangi Wei & Zhu (China), M. melanosomata Wei & Xin (China) and M. longipetiolata Wei & Zhong (China) (Gmelin, 1790; A. Costa, 1859; Mallach, 1936; Wei & Nie, 1998; Wei & Chen, 1998; Wei & Nie, 2003; Liu & Wei, 2005; Zhao & Wei, 2011; Zhu et al., 2012; Wu et al., 2012; Li et al., 2013a). Here, two species are described as new to science, M. elegansoma sp. nov. and M. reni sp. nov.
