Aggiungi al carrelloPhyllomedusa lemur is a leaf frog occurring in lower montane rain forests of Costa Rica and Panama. Only one locality is as low as 140 m a. s. l. Captive specimens from For- tuna, Panama, produced three types of vocalizations: a one- note advertisement call, an encounter call consisting of three to four notes emitted in close pr…oximity to another male or after another male's advertisement call, and a release call consisting of several notes. Aggressive behaviour of males consisted of clasping other males and non-receptive females and trying to make them drop off the perch. Four pairs depo- sited 72, 46, 43 and 30 eggs in 3, 2, 2 and 1 clutch, respectively. Clutches were deposited on leaves and the frogs made no attempts to wrap the leaves around them. Eggs hatched after 7 to 14 days (mean, 9.4, n =27 at 24 °C). Eggs covered by other eggs were retarded in development and often died. Metamorphosis was completed after 69 to 98 (mean, 81.5) days at SVL of 21.5-24 (mean. 22.8) mm. Under natural conditions, freshly metamorphosed froglets are larger (25-27 mm). Males developed weak nuptial pads after seven months. The reproductive biology of Phyllomedusa lemur (and other species of the P. buckleyi group) differs significantly from that of other Phyllomedusa species. Egg clutches are not wrapped in leaves and do not contain small empty egg cap- sules surrounding the other eggs. Vocalizations are less complex. In these respects, P. Iemur resembles the Agalychnis species. Perhaps, because of several morphological differences between Agalychnis and the P. buckleyi group, this latter group should be given generic rank. 8 pp., 16 figs, 4.
