Eight new species from China, , , , , , , and , are described and illustrated. differs from by having 5-9 irregular and papillae-like calli on each side in the sac of the lip, epichile with entire lobes, petals narrowly obliquely obovate and an apex that is not recurved. is easily distinguished from its relatives similar by having a long stem, pubescent ovary and sepals, epichile lobes with irregular and undulate margins, a subquadrate callus without teeth in the saccate hypochile. differs from by having a simple and lanceolate to ligulate lip, glabrous bracts and ovary, oblique and narrowly ovate petals. differs from by having white-veined leaves, oblong-lanceolate epichile lobes, and viscidium attached to the middle of the caudicle. is easily distinguished from its relatives similar by having distant pseudobulbs, shorter scape, an inflorescence with 9-16 orange-red flowers, shorter lateral sepals with a long acuminate apex, incurved and tubular apical margins, a papillate lip disk and triangular-subulate stelidia. is easily distinguished from its relatives similar by having narrow lanceolate leaves, shorter inflorescence with 1-3 greenish-yellow flowers, falcate-ovoid lateral sepals, a lip with small lateral lobes and 3 keels at the base. differs from by having shorter inflorescence, peduncles with 2 tubular sheaths, dorsal sepals with a retuse apex, lateral sepals with lower edges that are connate to each other and free and divergent toward the apex, obovate petals with an acute or slightly retuse apex. differs from by its 5-veined dorsal sepal, ovate-lanceolate lateral sepals, obliquely ovate-oblong petal, erose-toothed margins and obovate lip with a large, oblong basal callus, and an obtuse base. In addition, three species (, and ) are reported for the first time in China.
本文描述并图示了来自中国的八个新物种，即[物种名称1]、[物种名称2]、[物种名称3]、[物种名称4]、[物种名称5]、[物种名称6]、[物种名称7]和[物种名称8]。[物种名称1]与[对比物种1]的区别在于，唇瓣囊内每侧有5 - 9个不规则的乳头状胼胝体，上唇裂片全缘，花瓣狭斜倒卵形且顶端不反曲。[物种名称2]很容易与其相似的近缘种区分开来，其具有长茎、被毛的子房和萼片，上唇裂片边缘不规则且呈波状，囊状下唇有一个无齿的近方形胼胝体。[物种名称3]与[对比物种2]的区别在于，唇瓣简单，披针形至舌状，苞片和子房无毛，花瓣斜且狭卵形。[物种名称4]与[对比物种3]的区别在于，叶有白色脉纹，上唇裂片长圆状披针形，粘盘附着于蕊柱足中部。[物种名称5]很容易与其相似的近缘种区分开来，其假鳞茎相距较远，花葶较短，花序有9 - 16朵橙红色花，侧萼片较短，顶端长渐尖，顶端边缘内弯且呈管状，唇瓣盘有乳头状突起，蕊柱齿三角形钻形。[物种名称6]很容易与其相似的近缘种区分开来，其叶狭披针形，花序较短，有1 - 3朵黄绿色花，侧萼片镰状卵形，唇瓣有小的侧裂片且基部有3条龙骨状突起。[物种名称7]与[对比物种4]的区别在于，花序较短，花梗有2个管状鞘，背萼片顶端微凹，侧萼片下缘彼此合生，基部游离且向顶端分开，倒卵形花瓣顶端锐尖或微凹。[物种名称8]与[对比物种5]的区别在于，其背萼片有5条脉，侧萼片卵状披针形，花瓣斜卵状长圆形，边缘有啮蚀状齿，倒卵形唇瓣有一个大的长圆形基部胼胝体且基部钝圆。此外，三个物种（[物种名称9]、[物种名称10]和[物种名称11]）在中国首次被报道。
