Drewes' moss frog
© 2004 Robert C. Drewes (1 of 2)
Color: The dorsal surfaces are a uniform dark brown with paler legs. Warts are black against the brown background. The arms and legs are darkly marked with brown blotches on a pale background. A black mask extends from the nostrils through the canthal area to the arm insertion. The vocal pouch is black. The ventral surfaces are darkly marked against a pale background, as are the soles of the hands and feet (Channing, A., D. Hendricks & A. Dawood (1994) ).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: South Africa
Habitat: As the only way of knowing what species of the genus is being collected is by observing the male’s advertisement call, the only habitat presently known for this species is where the males issue their calls. Males call from ledges on moist, moss covered slopes, often concealed under vegetation (Channing, A., D. Hendricks & A. Dawood (1994) ).
Life History, Abundance, Activity, and Special Behaviors
Male Advertisement Call: Besides DNA, advertisement calls are the only way to distinguish between the four species of the genus Arthroleptella that reside in the mountains of the south-western Cape. The call for A. drewesii species consists of 5-10 notes in 0.70 seconds, somewhat evenly spaced, with a longer space between the last two notes. Some notes may double, and the notes are loosely grouped. The dominant energy of the call is between 3.9 and 4.0 kHz with a mean duration of 0.69 seconds Eggs and Young: The eggs are laid under moss of leaf litter in clutches of approximately ten eggs. Interestingly, the young hatch directly into developed frogs, skipping a tadpole phase (Channing, A., D. Hendricks & A. Dawood (1994) ).
