Two new species of darkling beetles of the genus Morphostenophanes Pic, 1925 (Coleoptera, Tenebrionidae, Stenochiinae, Cnodalonini) are described from Yunnan, China: M. jiaoziensis sp. nov. and M. yangshijiani sp. nov. Additionally, the female of M. bannaensis Zhou, 2020 is described for the first time. A new species group, the yangshijiani group, is proposed. Distributional maps for the two new species and an updated key to the elegantulus and yangshijiani groups are provided. Moreover, intraspecific variant individuals of the two new species are described, and the geographical distribution, elevational ranges, and phenological differences of these species are discussed. The factors contributing to the differences in populations of M. jiaoziensis are analysed.
