The Egyptian pipistrelle is a small bat with long ears, which are rounded at the tips, and long tragi (3). Its long, dense fur is usually dark brown in colour, yet can vary between shades of grey, reddish-brown and pale brown (3), with the fur on the underside being a lighter shade than the fur on the back. A characteristic white stripe, commonly more than five millimetres wide, runs along the wing membranes, and some individuals also have white skin on the fingers and the veins in the flight membranes (4). Egyptian pipistrelle females are often slightly larger than the males (4).
Due to a lack of obvious distinguishing features, it can be difficult to identify different species in the Pipistrellus genus, a name which comes from the Italian word ‘pipistrello’ meaning bat (5). However, the number of teeth is one character that may be used to distinguish between different pipistrelle species; the Egyptian pipistrelle typically has 34 teeth (5).
