摘　　要：记述采自云南省春蜓科 2 新种:卢氏奈春蜓 Nychogomphus lui, sp. nov. 和文山刀春蜓 Scalmogomphus wenshanensis, sp. nov.。模式标本保存于浙江自然博物馆昆虫标本室。This paper deals with descriptions of two new species from Yunnan Province, China. Type specimens are deposited in the Zhejiang Museum of Natural History. 1. Nychogomphus lui, sp. nov. (Figs. 1~7) Measurements (mm): Male: Body length 54, abdomen+app length 39, hindwing length 31. Male: Anal triangle 4 cells, 2 or 3 transverse nervures between sectors of from are to bifurcation of Rs in forewing, 1 in hindwing, anal loop 2 ells. Oblique antehumeral stripes connected with the collar below, black lines on lateral sutures rather thicker. Superior appendages apices curved strongly downwards; inferior appendages undulant curved, bifid almost to base, the two branches very closely apposed and the apical horizontal truncated in profile,curved strongly up to meet the superior appendages. Posterior lobe of middle segment of penis absent, anterior hamulus without posterior branch. This species somewhat resembles Nychogomphus flavicaudus (Chao), But easily recognizable by the inferior appendages of male brown, undulant curved, the apical third broad triangle as viewed from the side. Holotype: ♂ , Malipo County, Wenshan Miaozu Autonomous Prefecture, Yunnan Province, 28-Ⅴ-2000, coll. LU Sheng-xian; Paratypes: 2♂♂, same data as holotype. 2. Scalmogomphus wenshanensis, sp. nov. (Figs. 8~13) Measurements (mm): Male: Body length 50, abdomen+app length 38, hindwing length 32. Female: Abdomen+app 33, hindwing 34. This species is similar to Scalmogomphus falcatus Chao, but differs from the latter as follows: 1) frons black, with a very broad transvers greenish yellow stripe stripe on its crest, interrupted at the middle; 2) anterior hamulus deeply cleft into two branches, posterior branches short, about one third length of anterior branches; 3) upper surface of the inferior appendages with a spine situated slightly nearer the apex. Holotype: ♂, Malipo County, Wenshan Miaozu Autonomous Prefecture, Yunnan Province, 28-Ⅴ-2000, coll. LU Sheng-xian; Par
