description: 8. <i>Swinny’s</i> Horseshoe <b>Bat</b> <i>Rhinolophus swinnyi</i> <b> <i>French</i>:</b> Rhinolophe de Swinny <i>I</i> <b>German:</b> Swinny-Hufeisennase <i>I</i> Spanish: Herradura de <i>Swinny</i> <b>Taxonomy</b>. <i>Rhinolophus swinnyi</i> Gough, 1908, Ngqeleni District, Pondoland, Eastern Cape Province, South Africa. <i>Rhinolophus swinnyi</i> is in the <i>capensis</i> species group with <i>R capensis, R gorongosae, R rhodesiae, R simulator, R denti,</i> and <i>R alticolus,</i> and genetic data have placed it close to <i>R capensis.</i> Populations now attributed to A <i>rhodesiaewad. R gorongosae'were</i> previously included in <i> R swinnyi, <i>but</i> genetic and morphological data support their specific status. Monotypic.</i> Distribution. E South Africa, including KwaZulu-Natal and Eastern Cape provinces; specimens from Mpumalanga Province are tentatively included here. Descriptive <b>notes.</b> Head—body <i>c</i>. 42 <b>—</b> 47 mm, tail 18-27 mm, ear 17-2-21- 6 mm, hindfoot 8—9 mm, forearm 40- 8-45 mm. Pelage is soft and flufly, being pale gray dorsally (hairs with pale cream bases) and paler ventrally, <i>occasionally</i> off-white or <i>creamy</i>. Dorsal pelage can also be <i>bright</i> orange in orange morph. Males lack axillary tufts. Ears are short <b>(</b> 42 <b>-</b> 45 <b>%</b> of forearm length). Noseleaf has subtriangular lancet, with distinctly concave sides and bluntly pointed tip; connecting <i>process</i> is rounded (about the same height as sella); sella is naked, with slighdy concave sides; narial lobes at base of sella are comparatively low; and horseshoe is narrow (width 6-7- 4 mm), does not cover entire muzzle, does not have any lateral leaflets, and has deeply notched median emargination. Lower lip has three grooves, with lateral grooves being <i>occasionally</i> indistinct. <i>Wings</i> and uropatagium <i>are</i> brown. Baculum is distinguished from Roberts’s Horseshoe <b> Bat (<i>A</i></b> rhodesiae) by being shorter and not tapered and having narrower base. Skull is delicately built, with thin zygomatic arches; nasal swellings are rounded; frontal depression is very shallow and sometimes nearly flat; supraorbital ridges are weak; sagittal crest is absent posteriorly and very low anteriorly, being <i>weakly</i> developed; P2 is small but in tooth row, and C1 and P4 are well separated as a result; and P3 is tiny and completely displaced labially that allows P2 and P4 to touch or nearly touch one another. Chromosomal complement has 2n = 58 and FNa = 62. <b>Habitat.</b> Mostly savanna woodlands. In KwaZulu-Natal, <i>Swinny’s</i> Horseshoe Bat is found in montane <i>Podocarpus</i> (Podocarpaceae) mist forests. <b>Food and</b> Feeding. <i>Swinny’s</i> Horseshoe <b>Bat</b> is insectivorous and probably forages by slow hawking and possibly gleaning. <b>Breeding.</b> No information. <b>Activity patterns.</b> <i>Swinny’s</i> Horseshoe Bat is nocturnal. Call shape is <b>FM</b> /CF/FM, and peak F component is 104-9-106-7 kHz in South Africa. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Least Concern on <i>The IUCNed List.</i> This assessment includes populations now attributed to Roberts’s Horseshoe Bat and Gorongosa Horseshoe Bat (A <i>gorongosae).</i> Distribution ofSwinny’s Horseshoe Bat is now restricted to South Africa, and <i>it</i> is considered <i>relatively</i> rare. Populations might be threatened <i>by</i> local deforestation from logging and agricultural expansion. <b>Bibliography.</b> ACR (2018), Cotterill (2002a, 2013e), Csorba <i>eta</i> /.
