Siphlonurusdongxi Li & Tong, sp.十一月产自中国云南省香格里拉市，根据卵、若虫和有翅阶段进行描述。该新种与S.davidi (Navás, 1932)关系密切，可通过成虫的颜色、MP分叉点、阴茎、成虫第IX背板后外侧刺、第一个腹部背板若虫以及卵的结构来区分。新种与S.davidi具有相同的形态和结构特征，如长肘部，有许多居间，C、Sc、RA和RSa1之间的交叉脉被不同的色素包围，前翅CuP静脉的强烈弯曲，后翅的宽阔扩张，膜质阴茎叶融合而无齿，支持了新种复合体Siphlonurusdavidi群的主张。新物种的阴茎和卵的结构有助于了解Siphlonurus属的起源和进化。
Siphlonurusdongxi Li & Tong, sp. nov. from Shangri-La City, Yunnan Province, China, is described based on egg, nymph, and winged stages. The new species is closely related to S.davidi (Navás, 1932), and can be distinguished by the colour of the imago, the forking point of MP, the penis, posterolateral spines of tergum IX of imagoes, and first abdominal terga nymph, as well as the structure of the egg. The new species and S.davidi have the same morphological and structural characteristics, such as the long cubital area with many intercalaries, cross veins between C, Sc, RA, and RSa1 surrounded with distinct pigments, the strong curvature of vein CuP in the forewing, the broad expansion of the hindwing, the membranous penis lobes fused without teeth, supporting the proposition of a new species complex, the Siphlonurusdavidi group. The structures of the penis and the egg of the new species could help understand the origin and evolution of the genus Siphlonurus.
