the feet have a thin web between all five of the digits; it extends to the subarticular tubercle between the first to third digits, from the third to fifth it extends slightly beyond this tubercle. The third and fourth fingers are tipped with enlarged ball or disc-like pads, the other digits have much smaller discs, the feet smaller than the hands. The discs of the hands are equal to or wider than the tubercles. The skin of the back can be either smooth with some warts, but is never tuberculate. Adult males have nuptial pads and vocal slits. The dorsum (back) is dark brown, sometimes with a thin, light mid-dorsal stripe running down the centre of its back. The ventral surface has a white background colouration, sometimes tinged yellow or reddish on the undersides of the thighs and towards the end of the creature, and is covered with dark splotches. The groin and the back of the thighs are coloured chocolate brown with bright yellow dots or broad stripes on living specimens. The throat is dark brown or solid black, a lighter-coloured stripe runs down it. The iris is coloured coppery gold and is split through the middle with a horizontal dark brown line. Living specimens are more colourful than dead animals, the ventral surface is then described as bright yellow, usually tinged with salmon-pink. It has a karyotype of 2n=22. Distribution As of 2002 it has been collected from the Costa Rican mountain ranges (cordilleras) of the Guanacaste, Tilarán, Volcánica Central and the north of the Talamanca. It was seen in Panama some time before 2010 along the Río Claro in Bocas del Toro Province. Ecology Habitat The native habitat of Craugastor andi is tropical, wet premontane rainforest with bromeliads, usually close to streams, at elevations of to above sea level. Savage (2002) states that it has mostly been collected at an altitude of . In Panama it has been collected at . Behaviour It is a nocturnal, probably arboreal species. The frog is usually found near streams and has also been found up to 5m high in the water pools in the centres of many bromeliads growing as epiphytes on trees. Males call from along streams; females descend from trees to mate. Savage describes the call as "a deep glug, repeated several times". Breeding takes place during the first heavy rains of the wet season. Gravid females have
