description: 2. <i>Yunkeracarus apomys</i> Bochkov et OConnor sp. nov. (Fig. 54) <b>Description.</b> FEMALE (holotype). Body, including gnathosoma, 380 long (370–395 in 8 paratypes), 175 wide (175–185). Propodonotal shield with widely rounded posterior margin, length 55 (55–60), maximum width 60 (60–65). Setae <i>si</i> 30 (30–35) about 1.6–2 times shorter than <i>se</i>, 52 long (50–55). Distance <i>se–se</i> 57 (55–60), about 5 times greater than <i>si–si</i>, 9 (8–9). Bursa copulatrix opening dorsal. Sternum about 22 long. Posterior projections of coxal fields I distinctly developed, about 9 long, 13 wide. Distance between distal ends of apodemes II about 30. Two pairs of distinct, slightly sclerotized folds present ventrally on propodosoma posterior to coxal fields II. Distance <i>4a–4a</i> 33 (30–38), subequal or 1.5 times greater than <i>ps3–ps3,</i> 30 (20–30). Alveoli of setae <i>h1</i> and <i>h3</i> absent. Legs III and IV subequal in length, about 125 and 135 long, respectively (excluding pretarsus). Setae <i>cG</i> I–II microspines, about 2 long. Setal lengths: <i>1a</i> 9 (9–13), <i>c3</i> 13 (11–16), <i>cp</i> 35 (31–38), <i>h2</i> 145 (140–150), <i>vF</i> I about 25, <i>vF</i> II about 27, <i>mG</i> I–II 24–27, <i>gTI–II</i> 2–3, &amp;straightphi;I–II 10– 11, solenidia ω <i>1</i> I–II about 9. MALE (paratype). Body, including gnathosoma, 360 long, 170 wide. Propodonotum as in female. Propodonotal shield 54 long, 65 maximum wide. Setae <i>si</i> 25 long, 1.5 times shorter than <i>se,</i> 38 long. Distance <i>se– se</i> 57, about 4.5 times greater than <i>si–si</i>, 12. Sternum about 15 long. Posterior projections of coxal fields I very short and wide, about 9 long, 12 wide. Distance between distal ends of apodemes II about 35. Two pairs of distinct folds present ventrally on propodosoma posterior to coxal fields II. Aedeagus about 40 long, its posterior end situated at level of setae <i>g.</i> Length and width ratio of postgenital shield subequal, about 30 long. Distance <i>g–g</i> 17, about 1.3 times greater than <i>ps3–ps3</i>, 13. Alveoli of setae <i>h1</i> and <i>h3</i> absent. Legs III and IV subequal in length, about 125 and 140 long, respectively (excluding pretarsus). Setae <i>cG</i> I–II microspines, about 2 long. Setal lengths: <i>1a</i> 8, <i>c3</i> 9, <i>cp</i> 25, <i>h2</i> 135, <i>vF</i> I–II about 22, <i>mG</i> I–II about 17, <i>gT</i> I–II about 2, solenidia &amp;straightphi;I–II about 10, ω <i>1</i> I–II about 8. <b>Type material examined.</b> Female holotype (BMOC 92-1400 - 014) ex <i>Apomys</i> sp. C (<i>sensu</i> Heany <i>et al</i>. 1998) (Muridae) (FMNH 146895), <b>PHILIPPINES</b>: Romblon Prov., Sibuyan Is., 4.5km S, 4km E Magdiwang, 325m, 12º30'N, 122º31'E, 17 February 1992, coll. S.M. Goodman (SMG 4937); female and tritonymph paratype (BMOC 92-1400 - 033) ex <i>Apomys</i> sp. C (Muridae) (FMNH 146900), same locality, 20 February 1992, coll. S.M. Goodman (SMG 4982); 7 female and 1 male paratypes (BMOC 92-1400 - 012) ex <i>Apomys</i> sp. C (FMNH 146893), same locality, 16 February 1992, coll. S.M. Goodman (SCG 4928). <b>Type deposition.</b> Holotype and paratypes are deposited in FMNH, other paratypes in NMP, UMMZ and ZISP. <b>Host range and distribution.</b> This species is known only from the type host, an undescribed species of <i>Apomys</i> referred to as “sp. C” by Heaney <i>et al</i>. (1998), from the Philippines. <b>Etymology.</b> The species name is derived from the generic name of the host and is a noun in apposition. <b>Remarks.</b> This new species is most similar to <i>Y. muris.</i> In both species, setae <i>si</i> are distinctly shorter than <i>se</i>, the distance <i>si–si</i> is short, about 3–6 times shorter than <i>se–se,</i> setae <i>cG</i> I–II are microspines, about 2 long. It differs from <i>Y.muris</i> by the following characters. In females of <i>Y. apomys</i>, setae <i>si</i> and <i>se</i> are 30–35 and 50–55 long, respectively, the bursa copulatrix opens dorsally, the propodosoma bears two pairs of distinctly developed and slightly sclerotized folds ventrally. In females of <i>Y. muris</i>, setae <i>si</i> and <i>se</i> are 13–15 and 27–30 long, respectively, the bursa copulatrix opens terminally, and the propodosoma bears two or more pairs of weakly developed folds ventrally.
