The Altwelt-Rundblattnasen ( Hipposideros ) is a bat genus in the family of the Rundblattnasen with over 70 species that occur in the tropics of the old world. Most species live in the southern parts of Asia, New Guinea, the Solomon Islands and Australia, 14 species in Africa.

features

The Altwelt round-leaf noses include very large, medium-sized and small to very small bats. They differ from other round-leaf noses in the combination of the following features: the rear part of the nasal leaf has a more or less elliptical shape, the upper edge is smooth and does not have the three pointed outgrowths of the other round-leaf noses, reminiscent of a trident. The tail is almost completely embedded by the tail flight membrane ( uropatagium ), only in some species the last one or two vertebrae protrude. The crest does not extend to the back of the skull. The fur is usually reddish or brownish in color.

Systematics

The genus Hipposideros was introduced in 1831 by the British zoologist John Edward Gray . With over 70 species today, it is the most species-rich genus in the family of round-leaf noses (Hipposideridae). In the past , attempts have been made twice, in 1941 by George Henry Hamilton Tate and in 1963 by John Edwards Hill , to group the species into different species groups based on morphometric characteristics. Whether these groups are really monophyletic or received their common characteristics as a result of convergent evolution remains a matter of dispute to this day. Even the monophyly of Hipposideros is still uncertain to this day.
