A new genus, Promolotra gen. nov., including two new species, P. hponkanrazi sp. nov. (♂♀) and P. shankhaung sp. nov. (♂), is described from Myanmar. The new genus is similar to Molotra Ubick & Griswold, 2011 but can be distinguished by the completely fused bulb and cymbium, the presence of a receptacle, the absence of grooves connecting either the anterior or posterior pairs of spiracles, and the incised labium of both sexes.
