Allobates wayuu (Acosta-Galvis, Cuentas & Coloma, 1999)
|Species Description: Acosta-Galvis,Cuentas & Coloma,1999 Rev. Acad. Colomb. Cienc. Exact. Fis. Nat.,23: 226|
The larvae appear somewhat ovoid when viewed from the side. When viewed from above, the snout is ovoid and the edge of the mouth is visible. The eyes are located dorsolaterally, and the nostril is closer to the snout than to the eye. There is a short sinistral spiracle near the longitudinal axis of the body (Acosta-Galvis et al. 1999).
Allobates wayuu was formerly ascribed to the genus Colostethus. Frogs in Colostethus (or formerly in Colostethus) can be distinguished from other frogs by the following combination of characters: an unexpanded third fingertip; presence of a conspicuous dorsolateral band in some examples; presence of ventrolateral band; gular and abdominal regions with flecking; third finger expanded in males; white testicles. Allobates wayuu can be distinguished from the following Colostethus (or frogs formerly in Colostethus) species by the following characteristics: from C. imbricolus and C. pratti by the presence of webbing between fingers II – III and III – IV; from C. inguinalis by the presence of an enlarged third finger and webbing between toes II – III and III – IV; from Anomaloglossus lacrimosus by the lack of extensive webbing and the presence of a dorsolateral band; from Allobates marchesianus by the lack of an expanded third fingertip and length of finger I ≤ II; from Rheobates palmatus and Hyloxalus chocoensis by the lack of extensive webbing and the presence of a dorsolateral ventrolateral band; from Silverstoneia nubicola by the webbing between fingers II – III and III – IV and the presence of a dorsolateral band; from Allobates talamancae by the presence of dorsolateral, oblique lateral, and ventrolateral bands; from C. ruthveni by the presence of an oblique lateral and ventrolateral band, and having the length of finger I ≤ II; from C. lynchi by the lack of a shielded cloaca (Acosta-Galvis et al. 1999).
In life, the adult is generally brown. Both the arms and legs are cream colored, and the legs additionally have faint brown bars. The sides of the body are faint brown. The dorsolateral, oblique lateral, and ventrolateral bands are cream colored. The upper lip has a mild cream color. The underside is creamy with brown-gray markings on the throat that may indistinct. The fingertips and toe tips are obscure brown. In alcohol, the adult displays similar coloration as in life. The sides of the head are faint brown. The thigh has an uneven faint brown band. The underside is creamy with some diffuse brown spotting. The palms of the hand and feet are creamy and mildly speckled brown (Acosta-Galvis et al. 1999).
In life, the larva shows spotted black pigmentation throughout its body. In formalin, the back and sides are black. The underside is unpigmented. The tail is transparent, and shows diffuse black spotting. The muscular region of the tail is creamy (Acosta-Galvis et al. 1999).
The relative lengths of certain body parts with respect to the snout-vent length, such as the head, eyes, tibia, and feet differ from individual to individual (Acosta-Galvis et al. 1999).

This species was previously in the family Dendrobatidae and the genus Colostethus. Before the taxonomic revision of the Colostethus genus in 2006, Colostethus had 138 species, but now it only comprises 18 species with the remaining 120 species being distributed to either the family Dendrobatidae or the newly established family Aromobatidae (Grant et al. 2006).
