Boophis ulftunni Wollenberg, Andreone, Glaw & Vences 2008

Boophis ulftunni is a small frog, with males having an SVL of 21.8 to 24.2 mm, and females ranging from 32.0 to 37.1 mm in SVL. This frog has a slender body, with the head as long as it is wide, and also wider than the body. The snout is rounded in dorsal profile, and slightly truncate in lateral profile, with lateral nostrils located closer to the tip of the snout than to the eyes. The tympanum is distinct, rounded and measures approximately 40% the diameter of the eye. No supratympanic fold is present. The canthus rostralis and loreal region are slightly concave. Vomerine teeth are distinct and located posteromedian to the small and rounded choanae. The limbs are slender with single subarticular tubercles under the fingers and no recognizable metacarpal tubercles on the hands. The fingers are weakly webbed, and have moderately enlarged discs. Males have small, unpigmented nuptial pads on the inner side of the first finger. The relative length of the fingers is as follows: 1

This frog occurs in northeastern Madagascar, and may be widespread throughout the northeastern region. It is known from the Masoala Peninsula, as well as Tsararano, Anjanaharibe-Sud, and Marojejy. It is found both within and outside low- and mid-altitude rainforests, in pristine or re-grown secondary forests, and in forest corridors. The holotype was collected at an altitude of 610-630 m in the Masoala Peninsula. Paratypes were collected from 600-1326 m. Specimens from Marojejy Park were found at elevations approximately 1300 m above sea level.

Individuals were heard at night calling from high perches (2-4 m). Boophis ulftunni calls are trills (single notes with a series of short pulses, varying in interpulse duration), repeated at irregular intervals. A single or double click sound was sometimes also noted to occur between calls. No significant frequency modulation was observed. The dominant frequency was between 5247 and 6413 Hz, varying by geographic location (but the variation may also have been due to calling in choruses vs. in isolation).

This is a newly described species, so no data exist on population trends. It occurs in two protected areas, Marojejy National Park and Anjanaharibe-Sud Special Reserve.

Boophis ulftunni is a species of frogs in the family Mantellidae. It is endemic to Madagascar.
