Andinobates dorisswansonae (Rueda-Almonacid, Rada, Sánchez-Pacheco, Velásquez-Álvarez & Quevedo-Gil 2006)

Diagnosis:This species is one of only two known dendrobatids with only four toes visible on the hind feet. Toes I and II are partially or totally fused in Andinobates dorisswansonae. It can be distinguished from the other dendrobatid with four toes, A. daleswansoni, by the following characteristics: coloration (dark brown to black with irregular orange spots in A. doriswansonnae, vs. a red hood on the head, shoulders, and arms, and a brown or reddish brown posterior dorsum in A. daleswansoni); skin texture (completely smooth in A. doriswansonnae, vs. mostly smooth with a few small, flat warts in the sacro-coccigeal region in D. daleswansoni); amount of toe fusion (toes I and II partially or totally fused in A. doriswansonnae, vs. always totally fused in A. daleswansoni); and testes color in males (dark brown in A. doriswansonnae, vs. cream with brown reticulation in A. daleswansoni). Description:Andinobates dorisswansonae is a small species with a snout-vent length of about 16.8 mm (range: 16.28-17.1 mm) in males and 18.2 mm (range: 17.54-19.43 mm) in females. The head is wider than the body in males but much narrower than the body in females. The snout is rounded when viewed both from above and in profile, with a rounded canthus rostralis and a flattened, vertical, and weakly concave loreal region. No postrictal tubercles are present. Vomerine, maxillary, and premaxillary teeth are not present. The tongue is long (length 2x the width). Eyes are large and prominent, with horizontally elliptical pupils. The tympanum and tympanal ring are oval-shaped and covered by skin in the posterodorsal region, and the supratympanic fold is lacking. The hand is relatively large, with moderately expanded discs on all the digits and paired dorsal pads on the discs. The disc of finger I has a rounded distal edge, while all other finger discs have truncated or undulated distal edges. Hind limbs are relatively short. In this species, the first toe is reduced and partially or totally fused to the second, so that the foot appears to bear only four toes. Toe discs are rounded and slightly wider than the digits, but much smaller than finger discs. Relative length of fingers is III>IV>II>I and of toes is IV>III>V>II. Outer metatarsal tubercle is small, elongated, and protuberant but flattened. Inner metatarsal tubercle is larger and conical. The skin is smooth on the back, belly, and flank. Males have a thinner and slightly smaller body than females, with the head slightly wider than the abdomen. Males can also be distinguished by a wider disc on finger III and the presence of vocal slits. In life, coloration on the back, throat, chest, and upper belly is dark brown or black with irregular red or yellow-orange blotches. Black or sepia legs may have round, red spots. A bright red band is present over the upper lip, extending from the snout tip to the arm insertion. In preservative, red coloration becomes white, and dark areas may become slightly paler(Rueda-Almonacid et al. 2006).This species is syntopic with Andinobates tolimense, but can be distinguished by coloration (brown or dark brown with a metallic yellow-bronze head in A. tolimense) and morphology (toes are completely separate in A. tolimense) (Bernal et. al 2007).This species was described by Rueda-Almonacid et al. (2006) as Dendrobates dorisswansoni; the specific epithet was corrected by Frost (Amphibian Species of the World (http://research.amnh.org/vz/herpetology/amphibia/?action=references&id=7149) Database). A. dorisswansonae is named after Doris Swanson, a dedicated conservationist from Spokane, Washington committed to protecting biodiversity in global hotspots such as the Tropical Andes (Rueda-Almonacid et al. 2006). It is one of only two dendrobatids to have four toes on the foot due to the fusion of the first toe with the second. In A. dorisswansonae the two toes are partially or totally fused, while in A. daleswansoni the two toes are totally fused. This novel character may lead to the placement of these two species in a new genus in the future (Rueda-Almonacid et al. 2006). In 2011, the genus Dendrobates was subdivided into seven genera, including the new genus Andinobates by Brown et al (2011).

Endemic to Colombia. This species occurs on the eastern slope of the northern Cordillera Central in the Municipality of Falan, Department of Tolima, Colombia, at 1,780 m asl. It has been found only in a single patch of cloud forest less than half a square kilometer. The type locality is a mix of cattle pastures and small patches of forest in agricultural areas, with some areas recovering from logging. A thick layer of leaf litter covers the wet, sandy ground. Precipitation is between 1-2 m per year. There are two rainy seasons, and the area is often covered by a dense fog. Annual temperature ranges from 12-18°C. (Rueda-Almonacid et al. 2006).

A. dorisswansonae is a diurnal species found on the forest floor or in bromeliads 1.5-2 m above the ground. Nearby bodies of water are shaded by a 10-15 m high canopy of secondary vegetation with underbrush including heliconias and ferns. Some female specimens were found to contain 5-6 eggs in each ovary. Ova are brown with a diameter of 1.96-2.08 mm. (Rueda-Almonacid et al. 2006). This species is syntopic with Andinobates tolimense. The two species can be distinguished by coloration and toe number (Bernal et al. 2007).

A. dorisswansonae is relatively abundant at the type locality, which is part of Bosques de Florencia National Natural Park (Rueda-Almonacid et al. 2006), but the area it occupies is very small (less than half a square kilometer). Threats to this species include the loss of its forest habitat from conversion to coffee plantations, logging, and grazing, and illegal collection for the pet trade (Stuart et al. 2008). It is protected under CITES Appendix II, with the 1987 CITES coverage of dendrobatids extended to include this species (described in 2006).

A. dorisswansonae species most likely has skin toxins, as do other brightly colored dendrobatids.

Andinobates dorisswansonae, the dotted poison frog, is a species of amphibian in the family Dendrobatidae, endemic to Colombia in the outskirts of Falan and north of the department of Tolima. It is toxic to humans.

La ranita venenosa punteada​ (Andinobates dorisswansonae), es una especie de anfibio de la familia Dendrobatidae, endémico de las cercanías de Falan, al norte del departamento del Tolima, Colombia.

Su piel es de fondo negro brillante o marrón oscuro con manchas rojas, anaranjadas o amarillas.​ Se distingue además de otros dendrobátidos similares porque tiene el primer y segundo dedo del pie fusionado, característica que comparte únicamente con una especie cercana, Andinobates daleswansoni. Los machos miden entre 16,2 y 17,1 mm de longitud y las hembras entre 17,5 y 19,4 mm.​

Se encuentra entre la hojarasca, en bosques secundarios con buen dosel y presencia de bromelias, donde deposita sus renacuajos, a los que cuida y lleva en el dorso hasta una fuente de agua. Se alimenta de insectos, especialmente de hormigas.​

Fue descubierta por Oscar Javier Gallego Carvajal de la Universidad del Tolima en un fragmento de bosque secundario de la vereda El Llano, en Falan. La descripción de la especie fue hecha junto con José Vicente Rueda Almonacid, Marco Rada, Santiago J. Sánchez Pacheco y Álvaro Andrés Velásquez Álvarez, de Conservación Internacional Colombia y fue publicada en Zootaxa en 2006.
