(Fig. 56)  
 Yunkeracarus faini apodemi Fain et al. 1967: 79; Smith et al. 1985: 481; Zabludovskaya 1989: 64, 1990: 32.   
 Redescription. FEMALE (holotype). Body, including gnathosoma, 310 long (315–330 in 10 specimens from A. wardi from Pakistan), 156 wide (155–170). Propodonotal shield with widely rounded posterior margin, length 50 (45–49), maximum width 60 (55–60). Setae si 37 long (28–35), slightly longer or subequal to se 30 long (25–27). Distance se–se 57 (50–55), 5–6 times greater than si–si, 9 (7–9). Bursa copulatrix opening terminal. Sternum about 15 long. Posterior projections of coxal fields I distinctly developed, about 9 long, 13 wide. Distance between distal ends of apodemes II 22 (22–27). 2–3 pairs of weakly developed folds present ventrally on propodosoma posterior to coxal fields II. Distance 4a–4a 20 (25–27), 1.3–1.5 times greater than ps3–ps3, 15 (17–18). Alveoli of setae h1 and h3 absent. Legs III and IV subequal in length, about 105 and 115 long, respectively (excluding pretarsus). Setae cG I–II microspines, about 3 long. Setal lengths: 1a 12 (12–13), c3 16 (13–17), cp 30 (27–30), h2 135 (130–140), vF I–II about 27, mG I–II about 28, gT I–II about 4, solenidia ϕI–II about 10, ω 1 I–II about 10.   
 MALE (paratype). Body, including gnathosoma, 300 long (290–320 in 10 specimens from A. wardi from Pakistan), 160 wide (145–155). Propodonotum as in female. Propodonotal shield 60 (45–49) long, 60 (57–60) maximum wide. Setae si 26 long (27–29), subequal to se, 28 long (27–33), respectively. Distance se–se 55 (45–48), 5–6 times greater than si–si, 9 (8–9). Sternum about 13 long. Posterior projections of coxal fields I distinctly developed, 9 long, 12 wide. Distance between distal ends of apodemes II 25 (22–25). Two pairs of weakly developed folds present ventrally on propodosoma posterior to coxal fields II. Aedeagus 44 long, its posterior end situated slightly posterior to level of setae g. Length and width of postgenital shield subequal, about 25. Distance g–g 17 (17–18), 1.3 times greater than ps3–ps3, 13 (12–14). Alveoli of setae h1 and h3 absent. Legs III and IV subequal in length, about 105 and 117 long, respectively (excluding pretarsus). Setae cG I–II microspines, about 2 long. Setal lengths: 1a 11 (10–12), c3 13 (11–13), cp 27 (25–27), h2 115 (115– 130), vF I–II about 27, mG I–II about 28, gT I–II about 3, solenidia ϕI–II about 10, ω 1 I–II about 8.   
 Type material examined. Female holotype (IRSNB I.G. 24.714 A. 1515) and 2 female paratypes ex Apodemus sylvaticus (L.) (Muridae), BELGIUM: Wallonia Reg., Namur Prov., 50°20'N, 04°50'E, 1 November 1964, coll. J. Jadin; 7 female and 4 male paratypes (IRSNB) ex same host, NETHERLANDS: Limburg Prov., Horst, 51°27'N, 06°04'E, 14 March 1967, coll. F. Lukoschus.   
 Type deposition. Holotype is deposited in IRSNB.   
 Non-type material examined. Five females and 4 males (UMMZ, FMNH) (BMOC 90-1500-102) ex Apodemus wardi (Wroughton) (Muridae) (FMNH 140525), PAKISTAN: NW Frontier Prov., Malakand Div., Swat Dist., Yakh Tangai, 34°51'01"N, 72°36'53"E, 2076m, 23 April 1990, coll. S.M. Goodman (SMG 3868).   
 Host range and distribution. This species is known from mice of the genus Apodemus, A. sylvaticus (type host) from Europe (Belgium and the Netherlands), Ukraine (Zabludovskaya 1990), A. agrarius (Pallas) from South Korea (Fain et al. 1967), and A. wardi from Pakistan. The records of solitary specimens from Mus musculus L. (Muridae) and Microtus socialis (Pallas) (Cricetidae) from Ukraine (Zabludovskaya 1990) need additional confirmation.   
 Remarks. Y. apodemi was described as a subspecies Y. faini (Fain et al., 1967). It clearly deserves species status because it differs from Y. faini by several consistent characters. The most notable features of this species are the short distance between setae si–si, 7–11 and the bursa copulatrix opens terminally. In Y. faini the distance si–si is about 18, and the bursa copulatrix opens dorsally.
