Panorpodes brachypodus sp. nov.

( Figs 1–12 )

Holotype: Male, CHINA: CHONGQING: Beibei, 6.viii.1940. The antennae of the holotype are broken, with only scape and pedicel remaining on the right antenna, and six flagellomeres present on the left antenna. Other parts of the holotype are roughly in good condition. The right wings were removed and mounted in a permanent slide. Genitalia was removed and is now stored in glycerol in a vial. The slide and vial are kept together with the holotype. The specimen is deposited in the Shanghai Entomological Museum , Shanghai, China ( SHEM) (formerly Institute of Entomology , Academia Sinica , Shanghai, China , IEAS).

Diagnosis. The new species is very specific for its rather short stalk of the hypovalve, making it readily recognized from its congeners. Compared to its sole known Chinese congener, Panorpodes brevicaudatus ( Hua, 1998) from the Changbai Mountains, northeastern China, the new species has the forking point of vein M 1+2 (FM 1+2) lies before that of R 2+3 (FR 2+3), not as a little beyond FR 2+3 as in P. brevicaudatus ; each hypovalve has a rounded distal tip and five minute spines along the out margin near apex in the new species, while the hypovalve is triangular with truncate apex in lateral view, with numerous small black spines at apex and distal two third of outer margin in P. brevicaudatus . The ocellar triangle is yellowish brown in the new species compared to dark brown in P. brevicaudatus , although the color may fade over time.
