This paper reports four new species of Trombiculidae collected from western Hubei,China and also discusses the geographical distribution and relation with host biology of 16 known parasites(flea,acarid and sucking lice)of Typhlomys cinereus.All type specimens are deposited in the Medical Entomology Gallery,Institute of Microbiology and Epidemiology,Academy of Military Medical Sciences,Beijing.Trombiculindus(Plumosicola)wuhouyongi Liu et Ma,sp. nov.(Figs.1-5) Body ovate,length 237(227-240),width 195(186-209).Palpal setae formula N.N.BNN/7B.Galeal setae with 13-15 long branches.Scutum tetragonal,posterior margin biconvex.SB behind line of PLs.Sensilla shorter,and its base with 5-7 pairs of very small barbs,apical portion with 6-8 long branches.PL>AM>AL.PW/AP=3.67,PW/SD=1.87,AP<PS.Dorsal setae 43-52 in number,arranged as 2.10.(2.10).12.10.2=48;2.9(2.10).13.7.2=45 or 2.10.13.13.12.2=52.Ventral setae 42-58 in number(31-41 before,11-21 behind anus).NDV=90-106.Legs all 7-segmented,with specialized setae as Fig.4.Standard measurements(average):AW 81.7,PW 98.8,SB 38.3,ASB 34.9,PSB 17.7,SD 52.6,AP 26.9,PS 30.7,AM 70.8,AL 51.4,PL 94.9×11,Sn 68.7,HS 86.9,DS 93.6/76.1,VS 45/58.9,Ip 919(887-968).;Holotype and 7 paratypes larvae,collected from Typhlomys cinereus on the border between Wufeng County (30°1′N,110°6′E,about 1?200?m.a.s.l),Southwest of Hubei Province and Shimen County,Northwest of Hunan Province on 15 Apr.2000.;The new species is similar to T.(P.)saxiaensis Wang,Li et Shi,1988,but differs from the latter in:Scutum with longer PS,Sensilla shorter,and its base portion with 5-7 pairs of barbs,apical portion with 6-8 branches,posterior lateral setae and dorsal setae wider and longer;PL>AM>AL;NDV=90-106(in the latter species,scutum with shorter PS,sensilla longer,and its base portion bare,terminal 2/3 with 14-15 branches,posterior lateral setae and dorsal setae narrower and shorter distinctly,PL=AM>AL;NDV=61-69).Leptotrombidium(Leptotrombidium)wulingsh- anense Liu,Xiang et Ma,sp. nov.(Figs.6-10) Body ovate,length 274(254-300),width 219(226-229).Palpal setae formula N.N.BNN/7B.Galeal setae with branches.Scutum ladder-shape,SB slightly behind line of PLs.Sensilla base bare and distal half with about 12 branches.PL>AM>AL,PW/AP=3.4,PW/SD=1.8,ASB>2PSB;posterior lateral setae and humeral setae with slender and longer branches.Dorsal setae usually 28-31 in number,arranged as 2.8.8.6.6;2.8.6.6.4.2 or 2.8.9.8.4.Ventral setae 15-21 in number(13-15 front,7 or 8 behind anus).NDV=48-54.Legs all 7-segmented,with specialized setae as Fig.9.Standard measurements(average):AW 80,PW 95,SB 36,ASB 36.6,PSB 15.6,SD 52.7,AP 27.7,PS 29.9,AM 79,AL 59,PL 105,Sn 80.8,HS 102.4,DS 100.6/78,VS 62.9/80.2,Ip1?012(976-1?038).;Holotype and 10 paratype larvae,collected from Typhlomys cinereus in the border region between Wufeng County(30°1′N,110°6′E,about 1?200 m.a.s.l),Southwest of Hubei Province and Shimen County,Northwest of Hunan Province on 5 May 2000.;The new species is related to L.(L.)bawangense Zhao,1982,L.(L.)pipellae Traub et Audy,1954,L.(L.)periosum Traub et Nadchatram,1967 and L.(L.)insolitum Nadchatram et Upham,1966,but differs from the first in:anterior dorsal setae much longer,in length about as long as posteriolateral scutal setae;there are no thick setae at the dorsal posterior sub-margin and posterior ventral surface;scutum PW and Ip obvious larger.It differs from the second species in galeal setae with more branches;second row with more dorsal setae,arranged as 2.8.8.6.4 or 2.8.9.8.4=28-31;scutum AP and PL shorter.It differs from the latter two species in shorter distinctly scutum AM,AP and SD.Leptotrombidium(Leptotrombidium)typhlomyis Liu et Ma,sp. nov.(Figs.11-15)Body ovate,length 278.7(242-326),width 218.2(191-247).Palpal setae formula N.N.BNN/7B.Scutum rectangular,posterior margin biconvex.SB slightly behind line of PLs.Sensillae with 8-12 long branches on distal 1/2,and with 3-5 pairs of small barbs near its base.PW/AP=3.44,PW/SD=2.0,PL>AM>AL.Dorsal setae 56-75 in number,arranged 2.13.(14.4).15.(13.2).7.2=72;2.12.(12.6).16.12.
