Glischropus tylopus [Dobson, 1875]

Vesperugo tylopus Dobson, 1875: 473 ; Sabah, north Borneo , MALAYSIA (Collector unknown; BM(NH) 70.2.10.2) [ 199].

Glischropus tylopus [ 191].

Common English name: Thick-thumbed Pipistrelle

Barcode Index Number: Two DNA barcodes ( RONP 009-14 and RONP 024-14) which are from Perak, Peninsular Malaysia are not assigned with any BIN due to their short sequence length ( < 500bp). However, other DNA barcodes recorded as G. tylopus which were collected in Vietnam and Laos are associated with the BIN, BOLD: AAC 0085.

Remarks: All DNA barcodes (BIN, BOLD:AAC0085) recorded as G. tylopus from Vietnam and Laos (= Indochina) represent G. bucephalus which was recently described on the basis of longer forearms and distinctive cranial features [ 200]. Another species from Sumatra, Indonesia, G. aquilus is distinct from G. tylopus collected in Peninsular Malaysia on the basis of its darker colour and 12.4% divergence in cytochrome b mtDNA [ 201]. It is likely that the form occurring in Peninsular Malaysia represents G. tylopus sensu stricto based on the comparison of specimens from Peninsular Malaysia and Sabah = type locality (see Fig 6 in [ 201]). We did not perform any NJ analysis for G. tylopus as the DNA barcodes from Peninsular Malaysia are too short for comparison with other barcodes.

IUCN status: Least Concern

Recorded at: Pahang: Krau Wildlife Reserve [ 11], Tasik Chini [ 43], Tasik Bera Forest Reserve [ 56]; Selangor: Bukit Lanjan [ 40], Bukit Kutu Wildlife Reserve [ 51], Ulu Gombak [ 53, 54], Semangkok Forest Reserve [ 101]; Kedah: Ulu Muda Forest Reserve [ 57]; Kelantan: Air Panas-Gua Musang [ 61], Gua Musang [ 62]; Perak: Temengor Forest Reserve [ 111].

G. tylopus is a lowland forest inhabitant but has been recorded in hill forest [ 11, 14, 23]. Individuals have been found roosting in small groups in internodes of dead and broken bamboo, and sometimes in rock crevices and banana leaves, occasionally with Tylonycteris species [ 11, 14].
