Zoology, Academia Sinica in Bejing. 1. Angustella albonotata, sp. nov.(Fig. 1) Length (incl.
teg): ♂7.0mm～7.8mm,♀ 7.5mm～7.8mm. This species is similar to A. leucostriata Li et
Wang, but can be distinguished from the latter by: 1). colour pattern in pronotum and tegumen;
2). pygoferoblique apically; 3). connective relatively as long as paramere. Holotype: ♂,
Xishuangbanna Mengzhe, Yunnan, 4-Ⅷ-1958, Coll. by Chen Zhi xiang. Paratypes:1♂,
Xishuangbanna Menghai, Yunnan,25-Ⅶ-1958, Wang Shuyong; 1♂, Xishuangbanna Menga, 9-
Ⅷ-1958, Wang Shuyong; 2 ♂♂, Xishuangbanna Menghai, 20,25-Ⅶ-1958, Pu Fuji; 2 ♀♀,
Xishuangbanna Menghai, 25-Ⅶ-1958, Pu Fuji; 1♀, Xishuangbanna Mengzhe, 5-Ⅸ-1958, Pu
Fuji; 1♀, Xishuangbanna Menga, 9-Ⅷ-1958, Pu Fuji; 4♀♀, Xishuangbanna Menga, 4, 8, 9-Ⅷ
-1958, Wang Shuyong; 2♀♀, Xishuangbanna Menghai, 25-Ⅶ-1958, Wang Shuyong; 1♀,
Xishuangbanna Menga, Yunnan, 4-Ⅷ-1958, Chen Zhixiang. 2. Angustella nigrinota, sp.
nov.(Fig. 2) Length (inc. teg.) : ♂7.0mm. This species is similar to A. albonotata sp.nov. in
body characters and male genitalia, the major differences are as follows: 1). color patterns on
vertex different; 2). pronotum and scutellum all blackish; 3). forewing black with a small
roundish yellow whitish patch at middle costal margin; 4). arrangement of setae on subgenital
