Panorpa biclada, a new species of Panorpidae （Mecoptera）, is described and illustrated from the Daba Mountains of central China. It can be readily distinguished by the blackish thoracic nota with a light median stripe; forewings with only a prominent pterostigmal band at most in female, and no markings in male; the dorsal valve of aedeagus bifurcated medially into a short ventral branch and a long curved dorsal branch; the female genital plate with the main plate recurved ventrad into an arc-shaped lobe at the base, and the axis divergent broadly at the basal half.
