A new species of Miniopterus (Chiroptera: Miniopteridae) from lowland southeastern Madagascar
Abstract
Based on morphological, mensural and molecular characters, a new species of bat of the genus Miniopterus is described from Madagascar, M. petersoni. While showing some morphological convergence to the recently named M. sororculus, the species described herein possesses a number of external and cranial characters that separates the two. Further, molecular data indicate that these two taxa are not closely related and are from different portions of the Miniopterus clade. Based on current information, M. petersoni appears to have a distribution in the southeastern portion of Madagascar associated with littoral, lowland and transitional humid-dry forest formations. Populations in the far north of its range, at Montagne d’Ambre in the lower end of montane forest and near Maroantsetra in a lowland zone, are tentatively assigned to M. petersoni

Zusammenfassung
Auf der Basis von Körpermaßen, sowie morphologischer und molekularer Daten beschreiben wir eine neue Art der Gattung Miniopterus von Madagaskar: M. petersoni. Die hier neu beschriebene Art ähnelt morphologisch der vor kurzem beschriebenen Art M. soroculus. Miniopterus petersoni unterscheidet sich von M. soroculus in einer Reihe externer Maße und Schädelcharakteristika. Molekulare Daten legen nahe, dass die beiden Arten nicht näher verwandt sind, sondern von verschiedenen Bereichen des Miniopterus-Stammbaumes stammen. Nach den derzeit verfügbaren Informationen kommt M. petersoni in Küsten- und Tieflandregenwäldern von Südost-Madagaskar, sowie in Übergangswäldern zwischen Trocken- und Regenwäldern vor. Populationen im Norden Madagaskars, im Montanregenwald und tiefer gelegenen Ausläufern bei Montagne d’Ambre, sowie im Tiefland nahe Maroantsetra werden vorläufig ebenfalls M. petersoni zugeordnet.
