A NEW SPECIES OF ISCHNOCNEMA (ANURA, LEPTODACTYLIDAE) FROM HIGH ELEVATIONS IN THE ANDES OF CENTRAL BOLIVIA

A new species of Ischnocnema is described from high elevations in the Andes of central Bolivia. The new taxon occurs at the highest elevatio n reported for the genus and is allopatric from other species of Ischn ocnema; it is separated from its geographically closest congener, I. q uixensis, by more than 800 km. The new species differs most notably fr om congeners by the presence of subconical to round subarticular and s upernumerary tubercles on the feet, terminal discs, a flesh-colored ty mpanum and coccygeal stripe, and a high head width to length ratio. Ma les of I. quixensis and the new taxon have relatively larger tympana t han females. Frogs of the genus Ischnocnema share distinctive hand mor phology, many morphometric characteristics, eye morphology and colorat ion, and banding of the lips and limbs.
