Rhinolophus francisi thailandicus Soisook and Bates   subsp. nov.

( Figs. 1 View FIG , 3–6 View FIG View FIG View FIG View FIG ; Tables 1–2 View TABLE View TABLE )


PSUZC-MM.2008.51 (field number PS080420.6), adult male, body in alcohol, skull and baculum extracted, collected by Pipat Soisook, Tuanjit Srithongchuay, Piyawan Niyomwan and 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 m a.s.l.).



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.


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.
