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.
