The present paper gives the descriptions of four new species of the genus Yezoceryx Uchida from the Wuyishan Natural Reserve of Fujian province. Wi- thin this area, the well known type localities Guadun (Kua-tun) and Dazhulan (Ta-chu-lan) of many vertebrate animals and insects are located. Some impor- tant distinguishing characters of these four species are given in the following key as well as in the accompanying figures. Key to 4 new species of Yezoceryx 1.Brown, thorax and abdomen unmarked; ventral swelling of abdominal segment I in profile round and low (fig. I -2). .................................................................................................. ........................ Y. wuyiensis Chao, sp. nov. Thorax and abdomen marked with black or dark brown; ventral swelling of abdominal segment I in profile angularly elevated or hooked forward ............................................ 2 2. Middle band of flagellum and tip of ovipositor sheath light colored; mesopleurum with a very large black marking; basal area of propodeum inverted trapezoid, about as long as apically wide (fig.

Flagellum and ovipositor sheath not as above; mesopleurum unmarked; basal area of propo- deum wider than long. .......................................................................................................... 3 3.
