On 20 April 2007, we located a roosting site in a dilapidated house in the suburbs of Secunderabad consisting of five individuals of bats.  From 21 April 2007 to 31 January 2008, we collected the pellets under the roosting site on a fortnightly basis.  Collected pellets were stored in plastic containers for dietary analysis.  On 5 February 2008 all individuals were mist netted, sexed, measured and, all but one, were released.  One male specimen was retained as voucher (OUNHM.CHI.1.2008) and deposited in the Osmania University Natural History Museum, Department of Zoology, Osmania University, Hyderabad.  Observations carried out on the individuals of the roost and morphometrics revealed them as the Lesser Yellow House Bat Scotophilus kuhlii Leach, 1821 (Bates & Harrison 1997).  Analysis of the faecal pellets collected was done between 10 February and 10 March 2008.  Through this note, we report a new locality record of Scotophilus kuhlii Leach, 1821 in Andhra Pradesh and provide brief note on its diet.

The Lesser Yellow House Bat is a widely distributed species and has been recorded from Pakistan to Taiwan, Sri Lanka, Western Malaysia to Philippines and Indonesia (Bates & Harrison 1997; Simmons 2005).  In India, it is distributed in Andaman and Nicobar Islands, Andhra Pradesh, Bihar, Gujarat, Madhya Pradesh, Maharashtra, Meghalaya, Karnataka, Kerala, Orissa, Rajasthan, Tamil Nadu, Tripura, Uttar Pradesh and West Bengal (Bates & Harrison 1997; Molur et al. 2002).

From Andhra Pradesh, Scotophilus kuhlii has been reported from Kotalcheruvu in Kurnool District (Chakraborty et al. 2004) and from Koduru, Balapalli and Thummalabailu in Cuddapah District (Bates & Harrison 1997).  All these locations are south of Krishna River and so far there are no locality based reports of this species between rivers Krishna and Godavari in the eastern part of peninsular India.

Scotophilus kuhlii frequents both the rural and urban landscapes and is known to roost in crevices and holes in walls of huts and old buildings, caves, old temples, palm fronds, hollows in palm trees and dried leaves on trees (Wroughton 1915; Brosset 1962; Sinha 1986).

A brief description of the specimens from Secunderabad and their diet is provided below.



External: Dorsally, the pelage is soft and olive brown in colour and ventrally creamish (Image 1). On the throat, a distinct ‘collar’ is seen.  The muzzle is broad and blunt.  Ears are small compared to the head; the tragus is about half the size of the ear and is crescent shaped.  The tragus is separated from the pinna by a distinct notch.

Cranial: The skull is robust and broad; the lambda is prominent and projects well above the supraoccipital; the lambdoid crests are well developed; the sagittal crest is well defined posteriorly and bifurcates in the interorbital region (Image 2).

Dental:The upper incisor (i2) is unicuspid and is nearly in contact with the canine; the single upper premolar is large and two-thirds the height of the canine; m3 is greatly reduced; the three lower incisors are bicuspidate; the lower canine is large and curved; the first lower premolar (pm2) is very small and situated in between the canine and the well developed second premolar (pm4); the second premolar (pm4) is nearly two-thirds the height of the canine; m3 is very much reduced with the talonoid being reduced in comparison to the trigonoid (Image 3).

Baculum:The baculum is small, bluntly triangular in shape. On the dorsal view, the base seems wider than the apex and is very narrow in lateral view with wide base (Images 4 & 5).

Morphometric measurements (mm.): External: FA - 49.15; HB - 60.33; Tl - 48.80; E - 16.26; Hf - 10.8.  Cranial: GTL - 18.48; CBL - 17.46; CCL - 17.09; CM3 - 6.47; M3-M3 - 8.30; C1-C1- 6.13; M - 13.74; CM3 - 7.37; ZB - 13.02; BB - 10.03; PC - 2.98.  These measurements are that of the voucher specimen only, external measurements of other specimens of the roost is provided in Table 1.


Dietary Analysis

Dietary analysis was carried out following standard techniques (Whitaker 1988).  From each collection of faecal pellets 10-12 individual pellets were randomly selected and analysed.  Each individual pellet was moistened with alcohol and teased to reveal the insect parts.  The insect parts were then identified to the lowest possible taxonomic level following standard literature (Boror & DeLong 1963; Shiel et al. 1997).  The dietary analysis of Scotophilus kuhlii revealed that it majorly feeds on members of the orders Diptera, Coleoptera and Hymenoptera (Table 2).  The dipterans included representatives of the families Anisopodidae, Chironomidae, Culicidae and Scatophagidae.  The coleopterans included representatives of the families Carabidae and Scarabaeidae, while the hymenopterans were represented by Ichneumonidae.
