This large tree frog has been found only in the lowlands below elevation
of about 1000 meters, usually in arid tropical scrub forest. Calling
males were heard on rainy nights throughout the rainy season; in nearly
every instance both males and females were found in low trees and
bushes. On summer nights when there had been no rain, adults were found
sitting on bushes in the scrub forest.
At Coalcoman on July 1, 1955, a chorus was heard at midday. About forty
_Phyllomedusa dacnicolor_ were found in one guayava bush at the edge of
a recently dried pond. Individual males were calling; clasping males
were silent. The call is a barking groan. Fifteen individual egg masses
were hanging from branches and leaves in tear-drop fashion. Each egg
mass contained 100 to 350 pale green eggs, located only in the exterior
part of the clear gelatinous mass. Two composite egg masses appeared to
have been made up by egg deposition on the part of three to five females
(Pl. 2, Fig. 2).
As shown by Duellman (1957a), the characters used by Taylor (1952) to
diagnose _Phyllomedusa alcorni_ are sexually dimorphic. Funkhouser
(1957) apparently was unaware of this sexual dimorphism, for she
recognized _P. alcorni_ and _P. dacnicolor_ as distinct species.

One specimen of this large species was collected in 1951; it was found
on a low branch in tropical semi-deciduous forest at an elevation of 65
meters. In life there were olive-gray blotches on a pale gray dorsum;
the iris was a dark golden color.
This species, which is known from only a few specimens, seems to be
restricted to the coastal lowlands and low foothills from Guerrero
northward to Nayarit. Shannon and Humphrey (1957) described _Phrynohyas
corasterias_ from Nayarit. Their description was based on a small female
having a snout-vent length of 34.4 mm. The new species was diagnosed as
differing from _P. inf
