Holotype PSUZC-MM.2008.51 (field number PS080420.6), adult male, body in alcohol, skull and baculum extracted, collected by Pipat Soisook, Tuanjit Srithongchuay, Piyawan Niyomwanand Priwan Srisom, on 20 April, 2008. Type locality Pu Nam Ron Stream, Mae Nam Pha Chi WS., Ratchaburi Province, Western Thailand( 13º15’N, 99º2’E, 431 ma.s.l.).
Diagnosis This subspecies is very similar to the nominate subspecies from Borneo with a FA of 52.97 mmand a SL of 24.37 mm. The rostral swelling is relatively narrower than in the specimens from Borneo, with an AMSW and ALSW of 4.76 and 6.53 mm, respectively. The 3D1P is relatively short; it is 66.74% of the length of the 3D2P. The sagittal crest is less developed than in the nominate subspecies. Genetically, it differs from the nominate subspecies by 10.03% at a section of the cytochrome oxidase-I gene.
Etymology The subspecific name, thailandicus, means ‘of or from Thailand’ indicating where this subspecies is found. The proposed English name of the subspecies is ‘ ThailandWoolly Horseshoe Bat’.
Description and taxonomic notes As in the nominate subspecies from Borneo, the Thai subspecies, R. f. thailandicusis a mediumlarge Rhinolophus.The general appearance is similar to francisifrom Borneo and overlaps in size, with a FA of 52.97 mm( Table 1). The body mass (MASS) is 16.0 g. The height of the ear is of 23.81 mm. The noseleaf width (NL) is 12.21 mm( Table 1). The wing measurements are larger than those of R. f. francisi; the third metacarpal (3MET) is 37.47 mm; the fourth (4MET) is 42.47 mmand the fifth metacarpal (5MET) is 43.99 mm( Table 1). In the skull, the SL and CCL are 24.37 mmand 21.72 mm, respectively ( Table 2). The AMSW and ALSW are of 4.76 mmand 6.53 mm, respectively. The supraorbital ridge is very well defined and connected to a well-developed sagittal crest ( Fig. 3a). The zygomatic breadth (ZB) is 12.16 mmwhich exceeds the mastoid width (MW), 11.31 mm( Fig. 3a; Table 2). Each zygoma has a distinct triangular-shaped dorsal arch ( Fig. 3a). Both the upper and lower dentition are as in R. f. francisibut are slightly smaller in size; C–M3 is 9.30 mm; C1–C1 6.07 mm; M3–M3 8.86 mm. The palatal length (PL) is 3.21 mm( Table 2).
The morphological comparison with other species is as in the nominate form of R. francisi.The size of Thai specimen is the smallest of the species. It is intermediate in size between the slightly larger R. beddomeiand the slightly smaller R. trifoliatus( Tables 1–2; Fig. 5). As noted above, a future study with more specimens from Thailandmay prove that the subspecies from Thailandis specifically distinct.
