Expanded generic diagnoses of all life stages of <i>Yaeprimus</i> Sasa et Suzuki, 2000 (<i>Lunditendipes</i> Harrison, 2000, <b>syn. n.</b>) are given. <i>Yaeprimus tropicus</i> <b>comb. n.</b> is redescribed as an adult based on type material. Additionally, a new species <i>Y. balteatus</i> <b>sp. n.</b> from Oriental China is described based on the adult male and pupa. The phylogenetic position of <i>Yaeprimus</i> within Chironomini and the validity of the new species are explored based on concatenated five genetic markers (<i>18S</i>, <i>28S</i>, <i>CAD1</i>, <i>CAD4</i>, and <i>COI-3P</i>) through both mixed&#8722;model Bayesian inference and maximum likelihood methods. The results strongly support <i>Yaeprimus</i> as sister to <i>Imparipecten</i> Freeman, 1961, which counters a previously proposed systematical position based solely on morphology.
