Diagnosis

This subspecies is very similar to the nominate subspecies from Borneo with a FA of 52.97 mm and 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 ‘ Thailand Woolly Horseshoe Bat’.

Description and taxonomic notes

As in the nominate subspecies from Borneo, the Thai subspecies, R. f. thailandicus is a mediumlarge Rhinolophus   . The general appearance is similar to francisi   from Borneo and overlaps in size, with a FA of 52.97 mm ( Table 1 View TABLE ). 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 View TABLE ). The wing measurements are larger than those of R. f. francisi   ; the third metacarpal (3 MET) is 37.47 mm; the fourth (4 MET) is 42.47 mm and the fifth metacarpal (5 MET) is 43.99 mm ( Table 1 View TABLE ).

In the skull, the SL and CCL are 24.37 mm and 21.72 mm, respectively ( Table 2 View TABLE ). The AMSW and ALSW are of 4.76 mm and 6.53 mm, respectively. The supraorbital ridge is very well defined and connected to a well-developed sagittal crest ( Fig. 3a View FIG ). The zygomatic breadth ( ZB) is 12.16 mm which exceeds the mastoid width ( MW), 11.31 mm ( Fig. 3a View FIG ; Table 2 View TABLE ). Each zygoma has a distinct triangular-shaped dorsal arch ( Fig. 3a View FIG ). Both the upper and lower dentition are as in R. f. francisi   but 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 View TABLE ).

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. beddomei   and the slightly smaller R. trifoliatus   ( Tables 1–2 View TABLE View TABLE ; Fig. 5 View FIG ). As noted above, a future study with more specimens from Thailand may prove that the subspecies from Thailand is specifically distinct.
