100 . Selangor Woolly Horseshoe Bat

Rhinolophus luctoides

French: Rhinolophe du Selangor / German: Selangor-Wollhaar-Hufeisennase / Spanish: Herradura de Selangor

Other common names: Luctus-like Horseshoe Bat

Taxonomy. Rhinolophus luctoides Volleth et al., 2015 ,

“ vicinity (5 km north-east , approx. 600 m a. s.l.) of the Ulu Gombak Field Studies Centre (3 ° 19 ’ 29 ” N, 101°45 '12 ” E), Selangor, Malaysia .”

Rhinolophus luctoides is included in the trifoliatus species group. The species was only recently described, based mainly on karyotypic and limited morphological data. Specimens of this species clustered genetically with specimens from China and Myanmar that are currently placed in R. pemiger, R. morio was sister to this clade. In addition, a specimen from Vietnam had nearly identical karyotype, although a specimen from China had a highly distinctive chromosomal complement. This Vietnamese specimen was designated as R. cf. luctoides , although other specimens from Vietnam are currently included in R pemiger . These data suggest that R. luctoides may have a more substantial distribution, but the karyotypic variation and its systematic implications within this complex are not yet fully understood. The taxonomy of the R luctus complex is very confused (see R.perniger and R. luctus ). A possible hybrid of this species and R morio has been found. Much further study is needed. Monotypic.

Distribution. Montane regions of Peninsular Malaysia; the exact distribution of this species is uncertain, and it may be more extensive in continental South-east Asia.

Descriptive notes. Forearm 59-65 mm; weight 21-7-32- 2 g. The Selangor Woolly Horseshoe Bat is smaller than the Northern Woolly Horseshoe Bat ( R. perniger ) but similar in size to the Great Woolly Horseshoe Bat (. luctus ) and the Malaysian Woolly Horseshoe Bat (. morio ). Compared to the Malaysian Woolly Horseshoe Bat, the Selangor Woolly Horseshoe Bat has a larger baculum (4 mm long) that is more bulbous at the base, with straight shaft; longer lower tooth row; and usually smaller zygomatic width (with the exception of one female specimen with extraordinarily large zygomatic width). For general descriptive notes, see the species account for the Great Woolly Horseshoe Bat, as the morphological differences between the two species have not yet been fully clarified. Pelage appears to vary from chocolate brown and grayish brown to gray with a frosted appearance. Chromosomal complement has 2n = 32 and FNa = 60.

Habitat. The species has been found in selectively logged dipterocarp rainforest, at elevations above 600 m.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. Calls from a handheld female in the Cameron Highlands, Peninsular Malaysia, had a peak F of 42 kHz.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The IUCNRed List, due to its recent recognition as a species. The taxonomy and distribution of the Selangor Woolly Horseshoe Bat are highly uncertain at present, and much further study is needed before a proper assessment of status and threats can be made.
