The only other frog in Central America having red webs and anterior and
posterior surfaces of the thighs is _Hyla loquax_, which has a broad
head, extensive axillary membrane, single median vocal sac, and
uniformly creamy yellow flanks; furthermore, _loquax_ lacks conical,
pigmented supernumerary tubercles on the toes and a large prepollex with
horny nuptial spinules. _Hyla rufitela_ has red webbing, but in no
other diagnostic feature resembles _infucata_, for _rufitela_ is green
above, white below, and has angular prevomerine dentigerous ridges.

_Remarks._--Most specimens of _Hyla pseudopuma infucata_ were found on
bushes and low trees at night. Three males and one clasping pair were on
the ground. The habitat is humid lower montane forest where the amount
of rainfall is high. Although no breeding was observed nor calls heard,
it is presumed that this subspecies breeds in shallow, temporary pools,
like those utilized by the nominate subspecies.

The two localities where _Hyla pseudopuma infucata_ is known are in the
maze of ridges north of Cerro Pando on the Panamanian-Costa Rican
border. The Rio Claro is a tributary of the Rio Changena, in turn a
tributary of the Rio Changuinola, which receives many streams and rivers
draining the northern slopes of the highlands in Bocas del Toro Province
before flowing into the Caribbean. We reached the Rio Claro and Rio
Changena by walking from Finca Santa Clara on the Pacific slopes, over
the continental divide, and down the north slope of Cerro Pando.

The subspecific name is derived from the Latin _infucatus_, meaning
painted, in allusion to the red colors on the limbs and webs.
