Recent sighting records of five bat species from
Gunung Arong, Johor, Peninsular Malaysia
Identity of subject Fawn Roundleaf Bat (Hipposideros cervinus) (Mammalia: Chiroptera: Hipposideridae).
Location: Jalan Air Papan – Tanjung Resang, Gunung Arong Forest.
Habitat: Lowland, tall secondary forest.
Date and time: 26 March 2016, 20:00 hrs.
Description of record: An intact, freshly deceased Roundleaf Bat was found on the road shoulder of Jalan Air Papan – Tanjung Resang, a two-lane metalled road which dissects Gunung Arong Forest Reserve. The carcass had no visible evidence of injury or sickness. Measurements were taken as follows : head-body length 55.8 mm, tail length 26.0 mm, forearm length 50.5mm, tibia length 20.0 mm, ear height 13.9 mm.
Remarks: Based on the shape of the noseleaf , which has two lateral leaflets (with the intermediate leaflet narrower than the posterior noseleaf), and on the suite of measurements, this bat is identified as Hipposideros cervinus.
Hipposideros cervinus is common in primary, lowland dipterocarp forest at Krau Wildlife Reserve (KWR), Pahang, Peninsular Malaysia (Kingston et al, 2006). KWR is 230 km northwest of Gunung Arong. The range of this species is extensive: in addition to Peninsular Malaysia it also occurs in Sumatra, Java, Borneo, the Philippines, eastern Indonesia, New Guinea and Australia (Francis, 2008).
