The present paper deals with a new species,a new subspecies of the genus Leptotrombidum Nagayo et al .,1916 and a new species,a new species\|group of the genus Haemogamasus Berlese, 1889 from Shennongjia of Hubei Province, China. All type specimens are deposited in the Institute of Parasitic Diseases, Hubei Academy of Medical Sciences. Leptotrombidium (Leptotrombidium) dabashanense Liu et Ma, sp. nov. (Figs. 1-5) Body ovate, length 261(244\|286), width 213 (208\|218). Palpal setae formula N.N.BNN/7B. Palpal claws 3\|fored. Galeal setae 10-15 long barbs. Scutum rectangular. SB behind line of PLs. Sensillae filamentous, with 9-11 long branches on distal 1/2, and with 5-7 pairs of small barbs near its base. PL>AM>AL.PW>AW, PW/AP= 4.19, PW/SD= 2.0, AP<PS. Eyes 2×2 on ocular plate. Dorsal setae 32 in number, arranged 2.8.6.6.6.4. Sternal setae 2 pairs. Ventral setae 36 -51 in number (29-39 front, 7-12 behind anus). Legs all 7-segmented, with specialized setae as Fig. 4. Standard measurements (average): AW 80.9, PW 100.1, SB 39.6, ASB 32.7, PSB 15.1, SD 47.9, AP 24.4, AM 72.4, AL 51.3, PL 78.1, Sn 76.6,HS 76.9, DS 71.7/60.9, VS 39.5/50.5, IP 890. Holotype and 2 paratypes larvae, collected from Insectivora, from Shennonjia Forest Region (31°15′N, 109°56′E, about 2*!300*!m), Northwest of Hubei Province on 24 Apr.1995. The new species is similar to L. (L.) zhongdianense Yu et Yang,1981 and L.(L.) longimedium Wen et Xiang, 1984, but differs from the latter in scutum larger, ASB>2PSB,PL>AM>AL; IP>850 (in the latter two species, scutum small, ASB<2PSB, AM>PL>AL; IP<800). Leptotrombidium (Leptotrombidium) halidasys bashuense Liu,Ma et Hu, ssp. nov. (Figs. 6-10) Body ovate, length 339(301-364), width 234(221-266). Palpal setae formula N.N.BNN/7B. Palpal claws 3-fored. Galeal setae branches. Scutum rectangular, middle of posterior margin nearly straight. SB behind line of PLs. Sensillae filamentous, with 8-10 long branches on distal 3/5, with 5-7 pairs small barbs near its base. AM>PL
