摘　　要：蛩螽族 Meconematini隶属于蛩螽科 Meconematidae,是一类体形较小而纤弱 ,但活动非常敏捷的螽斯。我国记载约 1 0属 72种。俄罗斯直翅目分类学家 Gorochov( 1 993,1 998)对这一类群的分类系统进行了调整 ,根据雄性生殖器的构造 ,建立了不少新属及新亚属 ,并发表了相当多的新种。在 Gorochov确定的属及亚属特征中偏重了雄性的形态特征 ,对雌性和两性共有的一些特征却没有给予归纳 ,至使一部分仅知雌性的种类无法被正确归属。我们将根据现已掌握的材料 ,对一些属和亚属的地位重新进行划分 ,确立 1个较合理的 ,能客观反映其间亲缘关系及演化规律的分类系统。本文根据中国蛩螽族的材料 ,描述 1 0新种 ,分别隶属于优剑螽属 Euxiphidiopsis,东栖螽属 Eoxizicus和新栖螽属 N eoxizicus,其中的优剑螽属 Euxiphidiopsis和东栖螽属 Eoxizicus是由亚属提升为属的地位 ,和新的同物异名 (东栖螽属 Eoxizicus Goro-chov,1 993=亚栖螽属 Axizicus Gorochov,1 998)。原先的副剑螽亚属 Paraxiphid-iopsis Gorochov,1 993看作是优剑螽属 Euxiphidiopsis的 1个亚属。所有模式标本分别保存在中国科学院上海昆虫研究所 ,北京中科院动物研究所 ,天津自然博物馆和广州中山大学昆虫学研究所。This paper is based on material of the tribe Meconematini from China, ten new species are described, belonging to genera Euxiphidiopsis, Eoxizicus and Neoxizicus respectively. The genera Euxiphidiopsis and Eoxizicus is now raised from subgenera to generic status, and new synonymy (Eoxizicus Gorochov, 1993= Axizicus Gorochov, 1998 syn. n.). And the former subgenus Paraxiphidiopsis Gorochov, 1993 considered as a subgenus of the genus Euxiphidiopsis. Descriptions of the called taxa are given. The type specimens are deposited in the Shanghai Institute of Entomology, Academia Sinica (IEAS); the Institute of Zoology, Academia Sinica, Beijing (IZAS); the Tianjin Natural History Museum (TNHM); and the Research Institute of Entomology, Zhongshan University, Guangzhou (IEZU). Euxiphidiopsis Gorochov, 1993, stat. n. Xiphidiopsis Bey Bienko, 1971, Ent. Obozr., 50:845 (X. capricercus group) Xiphidiopsis (Euxiphidiopsis) Gorochov, 1993, Zoosyst. Rossica, 2(1):66 Xiphidiopsis (Paraxiphidiopsis) Gorochov, 1993, Zoosyst. Rossica, 2(1):67 syn. n. Type species: Xiphidiopsis (Euxiphidiopsis) motshulskyi Gorochov, 1993. The genus Euxiphidiopsis is raised from subgenus to generic status, original description see Gorochov, 1993. This genus is characterized by the head with a dark brown stripe behind each eye. The former subgenus Paraxiphidiopsis Gorochov, 1993 considered as a subgenus of the genus Euxiphidiopsis. 9 species of this genus are known. 1. Euxiphidiopsis (s. str) quadridentata Liu et Zhang, sp. n. (Figs.1～3) Male. Small sized. Coloration yellowish (living specimens possibly greenish). Head with a dark brown stripe behind each eye, pronotum with a dark brown stripe along each side of disc, genucular lobe of hind femora with a blackish spot at apex. Tegmina and wings fully developed. 10th abdominal tergite with a pair long, divergent processes at the hind margin; cerci simplex, slightly incurved and flattened; subgenital plate with four tooth near apex. Female unknown. Length. Body ♂9.0 mm; pronotum ♂3.5 m
