(Fig. 63)  
 Description. FEMALE (holotype). Body, including gnathosoma, 335 long (335–360 in 10 paratypes), 160 wide (160–165). Propodonotal shield with widely rounded and distinctly sclerotized posterior margin, length 48 (45–50), maximum width 65 (55–60). Setae si and se subequal in length, 30 (29–30) and 32 long (28–35), respectively. Distance se–se 60 (58–63), 4–6 times greater than si–si, 13 (10–13). Bursa copulatrix opening dorso-terminally or terminally. Sternum about 20 long. Posterior projections of coxal fields I distinctly developed, length and width subequal, about 9 long, 10 wide. Distance between distal ends of apodemes II about 25. Two–three pairs of distinct folds present ventrally on propodosoma posterior to coxal fields II. Distance 4a–4a [only one seta 4a present in holotype] (35–45), about 1.5 times greater than ps3–ps3, 25 (25–30). Alveoli of setae h1 and h3 present. Legs III and IV subequal in length, about 120 and 135 long, respectively (excluding pretarsus). Setae cG I–II microspines, about 2 long. Setal lengths: 1a 9 (9–11), c3 13 (13–17), cp 27 (25–30), h2 110 (110–115), vF I–II about 25, mG I–II about 25, gT I–II about 3, solenidion ϕI–II about 10, ω 1 I– II about 9.   
 MALE (2 paratypes). Body, including gnathosoma, 300–310 long, 140–145 wide. Propodonotum as in female. Propodonotal shield 48–50 long, 60-63 maximum wide. Setae si and se subequal in length, 25–27 and se 30–33 long, respectively. Distance se–se 50–55, about 5 times greater than si–si, 8–10. Sternum about 15 long. Posterior projections of coxal fields I distinctly developed, about 9 long, 15 wide. Distance between distal ends of apodemes II about 22. Two pairs of distinct folds present ventrally on propodosoma posterior to coxal fields II. Aedeagus about 43 long, its posterior end situated at level of setae g. Length and width of postgenital shield subequal, about 30. Distance g–g 25–29, about 2 times greater than ps3–ps3, 13–15. Alveoli of setae h1 and h3 present. Legs III and IV subequal in length, about 120 and 130 long, respectively (excluding pretarsus). Setae cG I–II microspines, about 2 long. Setal lengths: 1a 10–12, c3 13–15, cp 25–, h2 105–110, vF I–II about 20, mG I–II about 22, gTI–II about 3, solenidia ϕI–II about 10, ω 1 I–II about 8.   
 Type material examined. Female holotype, 14 female, 1 male, and 3 tritonymph paratypes (BMOC 95- 0917 - 131) ex Hylomyscus arcimontensis Carleton et Stanley (Muridae) (FMNH 155389), TANZANIA: Morogoro Region, Kilombero Dist., Udzungwa Mts., Udzungwa Scarp Forest Reserve, 4 km W, 5 km N Chita, 1460m, 08º28'30"S, 35º54'25"E, 14 August 1995, coll. P.M. Kihaule (WTS 1879); 5 female, 1 male, 2 tritonymph, and 2 larva paratypes (BMOC 95-0917 - 079) ex same host (FMNH 155388) and same locality, 8 August 1995, coll. P.M. Kihaule (WTS 1827).   
 Type deposition. Holotype and the most part of paratypes are deposited in FMNH, other paratypes in OSAL, UMMZ and ZISP; non-type specimens in FMNH, UMMZ.   
 Non-type material examined. Ten females, 2 males, 1 protonymph, and 1 tritonymph (BMOC 91-1350- 009) ex Praomys jacksoni (de Winton) (Muridae) (FMNH 145101), UGANDA: Western Prov., Kasese Dist., Rwenzori Mts, Mubuku River above Kyoha River, 1875m, 11 April 1991, coll. J.C. Kerbis (JCK 1768); 4 females and 1 male (BMOC 91-1350-002) ex same host (FMNH 145089) and same locality, 10 April 1991, coll. J.C. Kerbis (JCK 1745); 19 females, 1 male, 1 protonymph, and 1 tritonymph (BMOC 92-0605-099) ex same host (FMNH 168563), BURUNDI: Cibitoke Prov., Kibira National Park, Ndora Zone, Giserama Col., Gite, 1.1 km N, 0.8 km E Kirumura, 2100m, 19 August 1991, coll. J.C. Kerbis (JCK 2844).   
 Host range and distribution. This species is known only from central and east African murines, Hylomyscus arcimontensis from Tanzania and Praomys jacksoni from Uganda and Burundi.   
 Etymology. The species name is derived from the generic name of the host and is a noun in apposition.   
 Remarks. Y. hylomyscus sp. nov. is closely related to Y. apodemi, in both species, setae si and se are subequal, setae cG I–II are microspines, about 2 long, the distance si–si is very short, 8–10 long, and the bursa copulatrix opens terminally. This new species differs from all other known species of the genus, including Y. apodemi, by the presence of the alveoli of setae h1 and h3. In all other species, the alveoli of these setae are absent.
