Silverstoneia nubicola Dunn 1924

Near Threatened (IUCN 3.1)
Silverstoneia nubicola
Silverstoneia nubicola (Boquete rocket frog)

Common name

Boquete Rocket Frog



Species description based on Savage (2002). A tiny rocket frog (male to 20 mm, females to 23 mm). Males have a swollen middle finger.

Silverstoneia nubicola Adult 1


The dorsal surface is dark brown; the coloration becomes black along the sides. The brown and black portions are separated by a thin cream-colored line that extends from the groin forward to the eye. A second light line extending from the upper lip to the groin borders the black sides below; this line is more evident in males because the throat and chest are black. The upper surface of the thigh is mottled brown.

Silverstoneia nubicola Dorsal 1


The ventral surface is pale yellow, except in males.

Silverstoneia nubicola Ventral 1

Concealed surfaces

Some red-orange coloration is apparent where mottling is not extensive.

Life history

Breeding season

Breeding takes place year-round (Savage 2002). Males call during the early morning and late afternoon from territories on the forest floor (Savage 2002).


The body of the tadpole is oval-shaped, with a long tai, and very low tail fins (Savage 2002). Tadpoles are brown above, pale below (Savage 2002). Some darker pigmentation is generally present (Savage 2002).

Ecology behavior and evolution


Silverstoneia nubicola is a diurnal inhabitant of leaf litter (Savage 2002).


A rapid series of "peets" (Ibanez and Smith 1995)

Behavior and communication

Females deposit their eggs in leaf litter in the territories of males (Savage 2002). Males carry hatchlings to streams to continue development (Savage 2002).
