Two new species of Nematoda, Gairleanema pulchra sp. nov. and Axonolaimus dimorphous sp. nov. are described from Rizhao coast, the Yelllow Sea. Gairleanema pulchra sp. nov. is characterized by six inner labial setae with bulbous swelling, six long outer labial setae and four short cephalic setae in one circle, amphidial fovea oval-shaped, spicules L-shaped with proximal end slightly cephalated, gubernaculum boat shaped with proximal end hooked anteriorly, seven oval-shaped precloacal supplements and tail conico-cylindrical. With the species description here two species are considered valid now in genus Gairleanema. Axonolaimus dimorphous sp. nov. is characterized by four long cephalic setae, amphidial fovea elongated loop in males and loop-shaped in females, spicules arcuated, gubernaculum with dorsal apophysis slightly directed to caudal position and tail conico-cylindrical with caudal setae. With the species description here 34 species are considered valid now in genus Axonolaimus.
从黄海日照海岸发现了两种新的线虫物种，即美丽盖氏线虫（Gairleanema pulchra sp. nov.）和双型轴咽线虫（Axonolaimus dimorphous sp. nov.）。美丽盖氏线虫的特征为：有六个具球茎状肿胀的内唇刚毛、六个长的外唇刚毛和四个短的头刚毛呈一圈排列，头感器椭圆形，交合刺呈L形且近端稍向头部弯曲，引带呈船形且近端向前钩状，有七个椭圆形的泄殖腔前补充器，尾部呈圆锥 - 圆柱形。随着此处对该物种的描述，盖氏线虫属现在有两个被认为有效的物种。双型轴咽线虫的特征为：有四个长的头刚毛，雄性的头感器为细长的环，雌性的为环形，交合刺呈弓形，引带有背突且稍向尾部位置，尾部呈圆锥 - 圆柱形且有尾刚毛。随着此处对该物种的描述，轴咽线虫属现在有34个被认为有效的物种。
