Ⅹ. 1985. collected by Lian Zhenmin.2. Caryanda amplipenna sp. nov. (figs. 10-12)Closely allied to Caryanda pieli Chang and Caryanda glatiea You, but differs from both in the interocular distance about 2 times the width between antennae of the frontal ridge; the elytra shorter, its length about 1.6 times larger than its width; the subgenital plate of female shightly curved in the middle of posterior margin; and this new species is easily separated from 'Caryanda glauca You by the colour and shape of its bady.Male unknown.Length of body: (?) 32.5mm; length of pronotum: (?) 7.0 mm; length of elytra: (?) 4.5mm; length of hind femur: (?) 15.5 mm.Holotype (?), Sichuan: Liangping County, 18 Ⅷ. 1981, collected by Jiang Xuejiao.
