Eloquent Horseshoe <b>Bat</b> <i>Rhinolophus eloquens</i> French: Rhinolophe <i>éloquent</i> <b>/German:</b> Lautfreudige Hufeisennase <b>/Spanish:</b> Herradura <i>elocuente</i> <b>Taxonomy.</b> <i>Rhinolophus hildebrandti</i> [sic] <i>eloquens</i> K. Andersen, 1905, “ Entebbi [= Entebbe], Uganda.” <i>Rhinolophus eloquens</i> is in the <i>Junugatus</i> species group and has been included as a subspecies of <i>R hildebrandtii,</i> although <i>it</i> is generally recognized as a distinct species. <i>Rhinolophus eloquens</i> is sister to the <i>rest</i> of the <i>fumigatus</i> group. Two subspecies <i>recognized</i>. <b>Subspecies and Distribution.</b> <i>A e.</i> <i>eloquens</i> K Andersen, 1905 - S South Sudan, NE &amp; SE DR Congo, Uganda, Rwanda, Kenya, and Tanzania (including Pemba and Unguja Is in Zanzibar Archipelago); possibly also S Ethiopia, extending as far as Malawi and Mozambique. <i>R e.</i> perauritus De Beaux, 1922 — S Somalia. Descriptive <b>notes.</b> Head—body <i>c</i>. 68-72 mm, tail 20-45 mm, ear 21—38 mm, hindfoot 12—14 mm, forearm 53—63 mm; <i>weight</i> 13-40 g. Dorsal pelage is generally pale brown (hairs are dark gray basally); venter is paler. There is no orange morph. Males lack axillary tufts. Ears are medium in length (44—51% of forearm length). Noseleaf has long subtriangular lancet, with slightly concave sides and rounded tip; connecting process is large and rounded, terminating near tip of sella; sella is covered with longish hairs and is broad and rounded at top, with upper two-thirds being parallel-sided; and horseshoe is medium in width (114—12- 3 mm), covers muzzle, has lateral leaflets, and has deep median emargination. Lower lip has one groove. Wings and uropatagium are brown to dark grayish brown. Baculum is trumpet-shaped, with straight, cylindrical shaft. Skull is robust, with sturdy zygomatic arches (zygomatic width is much wider than mastoid width); nasal swellings are relatively high, being longer than they are broad; frontal depression is shallow to <i>relatively</i> deep; and sagittal <i>crest</i> is comparatively prominent anteriorly. Dental formula is commonly 11/2, C 1/1, P 1/2, M 3/3 (x2) = 28, or rarely 11/2, <i>C</i> 1/1, P 2/2, M 3/3 (x2) = 30,11/2, C 1/1, P 2/3, M 3/3 (x2) = 32, or 11/2, C 1/1, P 1/3, M 3/3 = 30. P2 is <i>very</i> small and completely displaced labially or completely absent, allowing <b>full</b> contact ofC1 and P4, and P3 is usually <i>absent</i> but, if present, is fully displaced labially and lies under cingula of P2 and P4, which are in contact. <b>Habitat.</b> Various semiarid savanna, mesic woodland savanna, and montane forest habitats, including <i>Acacia (</i> Fabaceae <i>)-</i> <i>Commiphora</i> <b>(</b> Burseraceae <b>)</b> brushland/thicket and mosaics of evergreen brushland and secondary <i>Acacia</i> savanna, at elevations up to 1500 m. <b>Food and Feeding.</b> No information. Breeding. No information. <b>Activity patterns.</b> The <i>Eloquent</i> Horseshoe Bat roosts in caves. There might be more information available in papers that misidentified it as Hildebrandt’s Horseshoe Bat <i>{hildebrandtii).</i> <b>Movements, Home range and Social</b> organization. No information. <b>Status and Conservation.</b> Classified as Least Concern on <i>The IUCN Red List.</i> The Eloquent Horseshoe Bat has a <i>relatively</i> wide distribution, but littie is known about its ecology. <b>It</b> seems to be most threatened by general habitat loss from agricultural expansion. <b>Bibliography.</b> ACR (201'8), Cotterill (2013b), Csorba et al.
