Two New Sawflies of the Genus Gilpinia in China (Hymenoptera, Symphyta, Diprionidae)

This paper describes two new sawflies of the genus Gilpinia, which attack the pine trees severely. The type-specimens are deposited in the collection of the Research Institute of Forestry, the Chinese Academy of Forestry, Beijing, China.1. Gilpinia massoniana, n. sp. (figs. 1,2)The new species is closely allied to Gilpinia variegata (Htg),but differs from the latter in having the clypeus, supraclypeual area, labrum, gena, temple, postocellar area with yellow color in the female, and in having the abdomen with black color in the male.Host plant: Pinus massoniana Lamb.Holotype, Chu County, Anhui Province, 20.

(figs. 3, 4)The new species is close to Gilpinia soda (Klug),but distinguishes from the latter by the thorax with black color, and by the lateral parts of pro-notum, the anterior half of the outer-lateral parts of mesoprescutum, the posterior half of the outer-lateral parts of mesoscutum, and the mesopleuron with reddish brown color.Host plant: Pinus tabulaeformis Carr.Holotype, Jingyuan County, Gansu Province, 30.
