101 . Malaysian Woolly Horseshoe Bat

Rhinolophus morio

French: Rhinolophe de Singapour / German: Malaya-Wollhaar-Hufeisennase / Spanish: Herradura de Singapur

Other common names: Jester's Horseshoe Bat

Taxonomy. Rhinolophus morio J. E. Gray, 1842 ,

“ Malacca , Singapore .”

Rhinolophus morio is included in the trifoliatus species group. It was previously included in. luctus but was recendy split, based on karyotypic and limited morphological data. Genetic data place this species as sister to a clade that includes. luctoides , as well as some specimens from China and Myanmar that are currently attributed to. perniger . There is a specimen that probably represents a hybrid between this species and. luctoides . Monotypic.

Distribution. Lowlands of Malay Peninsula; exact distributional limits are not well established.

Descriptive notes. Head-body 70-85 mm, tail 40-52 mm, ear 30-35 mm, forearm 60-69 mm; weight 25- 5-41 g. The Malaysian Woolly Horseshoe Bat is smaller than the Northern Woolly Horseshoe Bat (. perniger ) but similar in size to the Great Woolly Horseshoe Bat ( A luctus ) and the Selangor Woolly Horseshoe Bat (. luctoides ). Compared to the Selangor Woolly Horseshoe Bat, the Malaysian Woolly Horseshoe Bat has a smaller baculum (3 mm long) that is less bulbous at the base (having two bulbs jutting outward and a deeper medial bifurcation) with a straight shaft; has a shorter lower tooth row; and usually larger 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. Tropical forest.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. Echolocation calls of specimens from peninsular Thailand, probably referable to this species, had an average peak F of 40-42 kHz. Calls in Peninsular Malaysia had a range of peak frequencies of 40—42 kHz.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The IUCN ed List, as it is included under R luctus , which is listed as Least Concern. The taxonomy and distribution of the Malaysian 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.
