Rhinolophus Francisi is a 2015 described bat of the family horseshoe bats (Rhinolophidae), which is native to Southeast Asia.
description
Rhinolophus francisi is similar to the sympatric sister species Rhinolophus trifoliatus . With a forearm length of 52.9 to 54.7 millimeters and a skull length of 24.3 to 26.6 millimeters, it is a medium-sized bat. The coat color is evenly dark brown, similar to Rhinolophus sedulus and Rhinolophus luctus , but Rhinolophus francisi is between these two species in terms of body size. Like most horseshoe bats, Rhinolophus francisi has a typical nasal structure, consisting of two nostrils that resemble a horseshoe . The nasal leaves are darker than those of Rhinolophus trifoliatus and differ slightly in shape. Rhinolophus francisi calls like Rhinolophus trifoliatus in a range from 49.2 to 50.0 kHz, which is inaudible to the human ear.
Distribution and way of life
A female of Rhinolophus francisi was found in Sabah ( Malaysia ) in 1983 and two other specimens were caught in Indonesia in 2004 . The researchers believe that further genetic analysis of museum specimens as well as on-site animal studies will show that the species is widespread in Southeast Asia.
Little is known about the way of life of Rhinolophus francisi due to the recent discovery. Like all horseshoe bats, it most likely feeds on insects.
Systematics
The first descriptors discovered the species in the collection of the Natural History Museum in London , where the holotype had been stored in alcohol for 30 years. The species is named in honor of Charles Francis, who found the female in Sabah ( Malaysia ) in 1983 . Genetic analyzes showed that two other museum specimens that were caught in Indonesia in 2004 belong to the same species.
