Myotis horsfieldii

Records from Borneo Sabah: Danum Valley, Gomantong, Ma- dai, Sukau, Tepadong (Payne et al., 2000). Sarawak: Mulu NP, Niah NP (Payne et al., 2000). EastKal: Sungai Wain PF (Struebig et al., 2006 a). Comments Eight individuals were captured in harp- traps set across old logging skids on the slopes of the Tabalar formation. This spe- cies is distinguished from most other Myotis by the wing membrane being attached at the side of the foot. It is known to roost in crevices and bell-holes in caves and is asso- ciated with large areas of water (Payne et al., 2000). These authors report M. hors- fieldii from most lowland areas in Sabah and Sarawak, and the SAMD regard this species as widely distributed over much of Borneo. However, apart from a further re- cord from Sungai Wain in 2005, as far as we are aware, the Tabalar records are the first report of this species occurring in Kali- mantan.Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on pages 87-88, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460

Pio, unpublished data); Riam (Payne et al., 2000); Sebangau NP, Tanjung Puting NP (Struebig et al., 2006 b). Comments A male individual was captured in a harp-trap set in the forest understorey at Tabalar, and was easily distinguished from other Bornean Kerivoula by its near translucent wings and ear length (15.0 mm). It is considered a forest specialist (Kingston et al., 2003) with scattered distribution over Borneo (Boitani et al., 2006). However, as far as we are aware this is the first record for East Kalimantan.Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on page 90, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460

Comments This species was captured in harp-traps set in forest at all of the four formations, and was distinguished from K. intermedia by body mass (2 g) and short skull (CBL 10.16–10.36 mm). This Near Threatened (Hutson et al., 2001), forest specialist (Kingston et al., 2003) has been reported from forested sites throughout Sabah, and sympatrically with K. intermedia in Central Kalimantan and Sarawak (Boitani et al., 2006), but appears to be much rarer than K. intermedia.Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on pages 90-91, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460
Cynopterus horsfieldii Gray 1843
No full textCynopterus horsfieldii Gray, 1843 Horsfield’s fruit bat New material 1♂ (MZB M26857). Records from Borneo Sabah: Gomantong, Gunung Kinabalu, Sungai Inarad, Kota Marudu, Trus Madi (Yasuma and Andau, 2000). Sarawak: Ta- puh (Yasuma and Andau, 2000); Bau limestone formations (Mohd-Azlan et al., 2005); Gunung Pendrisen (Jayaraj et al., 2006). WestKal: Gunung Palung NP (Bhudel, 1996); EastKal: Bukit Soeharto (Yasuma, 1994). Comments Small groups (2–6 individuals) of this species were seen roosting near the entrances of Gua Dep at Baai, an unnamed cave at Tintang, and an unnamed cave at Berantai (also known as Tabalar Ulu) vil- lage near the Tabalar formation. An individ- ual from Berantai was captured in a hand net to confirm identification by skull length and to compare to material from other is- lands. The specimen compares favourab- ly, and exhibits the square molars with well developed cusps indicative of C. hors- fieldii. There are scattered reports of this species in Borneo (of which this is the sec- ond for East Kalimantan) where it has also been noted to roost in caves and forests (Ya- suma, 1994).Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on pages 73-76, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460
Miniopterus magnater Sanborn 1931

Records from Borneo Sabah: Batu Ponggul, Gomantong, Gua Liang, Madai, Poring, Pulau Balembangan, Upper Sungai Kuamat (Payne et al., 2000). EastKal: Bantol cave (Yasuma, 1994). Comments Nine individuals were captured in a harp-trap as they emerged from Gua Kelelawar at Tintang. This is the second re- cord in Kalimantan. Otherwise it is only confirmed in Sabah. M. magnater is the largest of the known Bornean Miniopterus (FA in Tintang 48.1–50.5 mm), but is often confused with M. schreibersii. The seven individuals taken as specimens from Tin- tang were confirmed as M. magnater by palatal width, M3–M3 (7.35–7.60 mm cf. 6.6–7.0 mm for M. schreibersii in Sabah — Payne et al., 2000), but it is possible that both species may be present at this formation as there is considerable overlap in external measurements.Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on page 87, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460
Chironax melanocephalus

Comments A single individual was captured in a harp-trap set across a rudimentary trail in disturbed forest at the Marang formation. C. melanocephalus is a small fruit bat, which, in Borneo, is known only from a few records in scattered forested localities (Boitani et al., 2006). Although no speci- men was collected, we distinguished this species by the presence of two pairs of lower incisors and distinct black fur on the head and neck as reported elsewhere in its range. Recent surveys have confirmed its presence in Sarawak and Kalimantan, so it is likely to be more widely distributed than was previously thought, but rare, and con- fined to forest areas as reported by all recent surveys.Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on pages 71-73, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460
Rousettus amplexicaudatus

WestKal: Gu- nung Niut NR (Colijn, 2005); Sungai Lan- dak (RMNH); Perbuah (Yasuma and Andau, 2000). Comments A single individual female was captured in a mist-net set over a stream at the Marang formation and collected as a voucher specimen. Unfortunately, the skull of this speci- men has since been mislaid in MZB, so we are unable to relate to comparative mate- rial. R. amplexicaudatus primarily roosts in caves (Kingston et al., 2006) and so it is like- ly that further surveys of caves at this site will record this species. In Borneo it is known from scattered localities in Sabah, Sarawak, Brunei and West Kalimantan. This capture is the first record for East Kalimantan.Published as part of Suyanto, Agustinus & Struebig, Matthew J., 2007, Bats of the Sangkulirang limestone karst formations, East Kalimantan - a priority region for Bornean bat conservation, pp. 67-95 in Acta Chiropterologica 9 (1) on page 76, DOI: 10.3161/1733-5329(2007)9[67:botslk]2.0.co;2, http://zenodo.org/record/394460
Myotis montivagus
No full textMyotis montivagus (Dobson, 1874) Large brown myotis New material 2♂♂ (MZB M26358 / 26778); 2♀♀ (MZB M26733 / 26734). Records from Borneo Sabah: Danum Valley, Madai, Sepilok, Tabin (Yasuma and Andau, 2000). Comments Five individuals confirmed by dentition of specimens were captured in a harp-trap emerging from Gua Sungai at the Marang formation, two of which exhibited a very high parasite load. This represents the first record for Kalimantan and extends the known range of this species in Borneo southward by about 350 km from records in Sabah (Boitani et al., 2006). This species is listed as Near Threatened by the IUCN (Hutson et al., 2001).
