The Bent-wingBat Miniopterus schreibersii andGoulds Bat Chalinolobus gouldii arereadily distinguished by their earswhich are about as broad as long,and do not project far above the Bent-wing is also distinguishedby the characteristic wing fold of thethird digit. According to Troughton(1967) the species with which thepipistrelle is most likely to be con-fused is the Broad-nosed Bat Nycti-ceius rueppellii. I have not seen fivespecimens of the latter but its ex-ternal characteristics are apparently.
