Yunnanilus macrolepis Li,Tao et Mao,sp nov (Figs 1 3) Holotype,No 9307001 Standard body length 92?mm,collected from Xuetian Longan(24°50′N,104°20′E),Luoping County,Yunnan,Jul 1993 Paratypes 8 specimens,No.9307002 03,9509001 06,body length 61 92?mm,collected from the same locality as the holotype D iii 7 8;A ii 5;P i 9 10;C 14 15;vertebrae 4+(34 35)+1(2 specimens) Gill rakers 15 on the inner row of the first gill arch Body depth in standard body length 4 8 6 1(5 1),head length 4 1 4 7(4 3),length of caudal peduncle 6 1 9 0(7 9),depth of caudal peduncle 8 3 10 7(9 3) Snout in head length 2 4 3 2(2 7),eye 5 3 8 0(5 8),interobital width 2 5 3 8(3 2) Depth of caudal peduncle in its length 1 0 1 4(1 2) Diagnosis.This new species distinguishes from as far as known within the same genus,by the followings given:1) with rather large and dense scales on body surface;2) distance from origin of dorsal fin equals it to caudal fin base;3) lateral line incomplete,only appears on 3 7 scales;4) barbels much longer Yunnanilus longidorsalis Li,Tao et Lu,sp nov (Figs.4 6) Holotype No 9411001,standard body length 37?mm,collected from Longtan Pool Agang (25°04′N,104°07′E) ,Luoping County,Yunnan,Nov 1994 Paratypes 10 specimens No 941102 03,9204006,9506001 07,standard body length 29 37?mm,collected from the same locality as the holotype D iii 11;P i 10 11;V i 6;A ii 6;C i 14 i Gill rakers 8 on the inner row of the first arch,vertebrae 4+32+1(1 specimen) Body depth in standard body length 3 5 4 6(3 9),head length 3 5 4 1(3 8),length of caudal peduncle 5 4 8 2(6 4),depth of caudal peduncle 10 3 12 3(11 0) Snout in head length 1 9 2 6(2 2),eye 3
