The Réunion mastino bat ( Mormopterus francoismoutoui) is an African bat species of the genus Mormopterus found on Réunion . It was listed as the Mauritius mastino bat ( Mormopterus acetabulosus ) until 2008 .
description
The Réunion Mastino bat is a large member of the genus Mormopterus and weighs an average of about 6 g. The head-trunk length of the holotype is 94 mm, the tail is 39 mm long. The back fur is short and dark brown, the belly side a little lighter in color. The membranes are also colored black-brown. Males have a gland on their necks that females lack. The ears have not grown together. As with other representatives of the bulldog bats , the upper lips are wrinkled. On average, the body size and weight are slightly smaller than that of the Mauritius Mastino bat.
Systematics and distribution
The Réunion Mastino bat was listed as Mormopterus acetabulosus until 2008 . The species were separated due to morphological differences in ears and body size, as well as genetic differences. The Mauritius mastino bat ( M. acetabulosus ) is endemic to the island of Mauritius after species segregation . The Reunion Mastino bat lives only on the island of Reunion . No subspecies are distinguished. Finds of the Réunion and / or the Mauritius Mastino bat at the beginning of the 20th century near Durban can probably be explained by the regular shipping traffic between the Mascarene Islands and South Africa , during which the animals may have traveled in the holds of the ships. A single finding of the species from Ethiopia can possibly be explained by migration.
Way of life
Reunion mastino bats are nocturnal. The species is widespread on Réunion, it occurs from the coast to heights of 2000 m above sea level. Roosts are found in rock caves and crevices, but also in bridges and in buildings. The largest known quarter, a rock grotto in Les Trois-Bassins , is inhabited by a colony of around 10,000-25,000 individuals during the summer. Colony sizes of up to 65,000 animals are known. Winter quarters of the species are not known, the animals may migrate. The young animals are born around the middle of December, and the young animals do not leave the nursery until the end of May.
Etymology and history of research
The Réunion mastino bat was listed as the Mauritius mastino bat ( Mormopterus acetabulosus ), which occurs on the nearby island of Mauritius , until 2008 . Molecular genetic studies show that both species are closely related but distinct species. Morphological differences in size, weight, skull and tooth features confirm this.
The holotype was collected by Steven M. Goodman and Jean-Michel Probst in 2006 on Réunion in the municipality of La Possession . The specific epithon honors Dr. Francois Moutou, who campaigns for the protection of vertebrates on the Mascarene Mountains.
Danger
The IUCN classifies the species as not endangered (“least concern”) due to its frequency.
