The pomona round-leaf noses ( Hipposideros pomona , synonym : Paracoelops megalotis ) is a bat from the family round-leaf noses (Hipposideridae).

A damaged stuffed specimen that is in a museum in Paris was described in 1947 under its own generic and species name as Paracoelops megalotis . The specimen found in northern Vietnam in 1945 was later considered to be a representative of a genus that was extinct in modern times , until its similarity to the pomona round-leaf nose was recognized and Paracoelops megalotis was synonymous with Hipposideros pomona .

features

The length of the head and trunk is between 45 and 48 millimeters, depending on the population, and the length of the tail is around 30 to 33 millimeters. The bat weighs 6 to 8 grams. The fur is mainly made up of long hair on the back. It's brown on the back and lighter on the belly, from dark orange to gray and light gray.

The length of the arms varies from around 39 millimeters in the populations in southern India, around 41 millimeters in specimens in northeast India to 43.5 millimeters in southern China. The total skull length is 16.6 millimeters in the south Indian populations, around 18 millimeters in northeast Indian and Thai specimens, and 17 to 17.5 millimeters in southern China. The species has relatively large ears, around 19 to 23.5 millimeters in length. The related species Hipposideros cineraceus only has an ear length of 13.0 to 17.0 millimeters, Hipposideros bicolor one of 17.5 to 21 millimeters.

distribution

The Pomona round-leaf nose is widespread from southern and northwestern India via Nepal , Bangladesh , Myanmar , Cambodia , Laos and Vietnam to Thailand and Malaysia and southern China. It occurs at altitudes up to 1900 meters above sea level.

There are three subspecies, but it is difficult to differentiate them from one another:

  • Hipposideros pomona pomona for the southern Indian distribution
  • Hipposideros pomona gentilis for the populations in northwest India, Bangladesh and parts of Southeast Asia
  • Hipposideros pomona sinensis for populations in southern China and on the island of Hainan

Way of life

The species lives in colonies from a few to hundreds of individuals in caves and crevices, but also in abandoned human settlements. It flies relatively low and feeds mainly on insects.

Systematics and taxonomy

Using specimens from the Natural History Museum in London, Knud Christian Andersen established a number of new species, including the Pomona round-leaf nose ( Hipposideros pomona ) and the species Hipposideros gentilis with four subspecies, including Hipposideros gentilis sinensis , which later became synonymous with Pomona round nose were viewed. His work was not finished when Andersen disappeared without a trace in 1918. The study was published by Oldfield Thomas that same year .

The numerous species of the genus of the Altwelt-Rundblattnasen ( Hipposideros ) are divided into five groups. The Pomona round nose belongs to the Hipposideros bicolor group.
