The new species is characterized by face very short, median length shorter than clypeus; clypeus 2.9 × as wide as long, apical margin with weak median convex; area basalis of propodeum very short, lateral carinae indistinct; hind coxa partly irregularly black; fourth and subsequent metasomal tergites black. A key to species of Dicaelotus known in China is provided.
