57. Robinson’s Horseshoe Bat Rhinolophus robinsoni French: Rhinolophe de Robinson I German: Robinson-Hufeisennase I Spanish: Herradura de Robinson Other common names: Peninsular Horseshoe Bat Taxonomy. Rhinolophus robinsoni K. Andersen, 1918, “ Kao Nawng, Bandon [Surat Thani Province], Lower Siam [= Thailand].” Included in the megaphyllus species group, and appears to be sister to a clade that includes A philippinensis, R megaphyllus, R celebensis, and A virgo, based on limited genetic data. A robinsoni has often been treated as a subspecies or synonym of A megaphyllus, but morphological and genetic data support their specific separation. In addition to the two subspecies recognized here, a third, thaianus. described from northern and western Thailand by J. E. Hill in 1992 (originally named siamensis by D. A. McFarlane and B. R. Blood in 1986 but this name is preoccupied) is commonly recognized; however, it this name is probably a synonym of A chaseni which is presently accepted as monotypic. Two subspecies recognized. Subspecies and Distribution. A r. robinsoni K. Andersen, 1918 - Malay Peninsula. A r. klossi K. Andersen, 1918 - Tioman, Pemanggil, and Aur Is off SE Malay Peninsula. Descriptive notes. Head-body 47-55 mm, tail 19-29 mm, ear 16-23 mm, hindfoot 9 mm, forearm 40-46 mm; weight 6-13 g. Dorsal pelage is dark brown to reddish brown, whereas ventral pelage is slightly paler. Ears are of medium length. Noseleaf has long, broadly triangular lancet that is practically straight with pointed tip; connecting process is high and rounded; sella is broad basally and gets slightly wider in middle before narrowing abruptly before squared-off tip; horseshoe is wide, at 8-3— 9- 2 mm, nearly covers muzzle, has small but noticeable median emargination, and has lateral leaflets that are mostly covered by horseshoe. Lower lip has three mental grooves. Skull is of medium build; anterior nasal swellings are moderately developed and globular; sagittal crest is low and braincase is elongate; frontal depression is longer than it is wide, and is clearly defined; supraorbital crests join sagittal crest more or less behind mid-orbit; rostrum is elongated. P2 is small with well-developed cusp and is within tooth row labially, separating C 1 and P4 widely; P3 is partially or completely displaced labially. Habitat. Known from mixed deciduous forest and lowland dipterocarp forest in Thailand and from lowland and hill forest in Malaysia. Food and Feeding. No information. Breeding. No information. Activity patterns. Robinson’s Horseshoe Bat is nocturnal. It has been reported roosting in crevices in rocks and in palms in the understory, in Malaysia. Call shape is FM/CF/ FM with a F of 64-68 kHz. Movements, Home range and Social organization. Robinson’s Horseshoe Bat probably roosts in small colonies. Status and Conservation. Classified as Near Threatened on The IUCN Red List Robinson’s Horseshoe Bat is considered rare throughout its relatively restricted range (as currently known). It is likely threatened by deforestation for logging, agriculture, and fires. Very little is known of its ecology or potential threats, and further research is needed. Bibliography.

Rhinolophus robinsoni Andersen, 1918 Rhinolophus robinsoni Andersen, 1918: 375; Khao Nawng, Bandon, THAILAND (Federated Malay States Museum, presenter; BM(NH) 1918.8.2.1) [117]. Common English name: Peninsular Horseshoe Bat Barcode Index Number: There are no DNA barcodes recorded under this name on BOLD. Remarks: R. robinsoni was previously considered to be conspecific with R. megaphyllus [9] but is now recognised as a distinct species [98]. Specimens recorded as R. megaphyllus from Peninsular Malaysia [46] should be updated to R. robinsoni. IUCN status: Near Threatened Recorded at: Pahang: Krau Wildlife Reserve [11], Fraser Hill [23, 140], Pulau Tioman [23], Kenong and Gunung Aais [100]; Johor: Pulau Aur and Pulau Pemanggil [23], Gunung Panti and Labis Forest Reserve [100]; Perlis: Wang Kelian State Park [50]; Kelantan: Gua Musang [62]; Melaka: Unspecified [68]; Negeri Sembilan: Gunung Angsi Forest Reserve [100]; Perak: Kledang Saiong Forest Reserve [100]; Pulau Pinang: Bukit Panchor [100]. Recorded as R. megaphyllus at Perak: Temengor Forest Reserve [46]. R. robinsoni inhabits forests primarily and has been recorded in lowland and hill forests roosting in rock crevices and palm leaves [11, 14]., Published as part of Voon-Ching Lim, Rosli Ramli, Subha Bhassu & John-James Wilson, 2017, A checklist of the bats of Peninsular Malaysia and progress towards a DNA barcode reference library, pp. 1-65 in PLoS ONE 12 (7) on page 34, DOI: 10.1371/journal.pone.0179555, http://zenodo.org/record/4251352, {"references":["117.
