Bolitoglossa guaneae differs from other Colombian salamanders by many different aspects. It differs from B. adspersa, B. hiemalis, B. hypacra, B. ramosi, B. savagei, B. tatamae, B. walkeri and B. vallecula by not having basal webbing between toes instead having extensive webbing with free tip. It is distinguished from B. altamazonica by having a longer third finger. The ventral surface in B. guaneae is brown with white dots, which distinguishes it from B. biseriata and B. silverstonei. The lack of digital depression distinguishes it from B. medemi, more protruding eyes distinguish it from B. lozanoi and B. nicefori. In having dark brown dorsal and lateral surfaces, B. guaneae is distinguished from B. phalarosoma. Bolitoglossa guaneae differs from B. sima by less extensive webbing. And lastly, B. pandi and B. capitana are larger than B. guaneae (Acosta-Galvis and Gutierrez-Lamus 2012).
The color in life is dark brown on the dorsum with some mottled or white streaks. The guanophores are a diffuse pale blue and cream with reddish marks visible in some individuals. The sides of the animal are brown with cream spots sometimes mottled white with faint blue guanophores. The hindlimbs have a dark brown coloration with a little reddish tint. The tail can range from light to dark brown with your occasional white streak. The tail can be mottled white as well but not always. The iris is copper without any black reticulations (Acosta-Galvis and Gutierrez-Lamus 2012).
The color in preservation is dark brown from the head to the tail with feet and hands light brown. The belly is also dark brown with a few cream patches and cream guanophores (Acosta-Galvis and Gutierrez-Lamus 2012).
Males exhibit secondary sexual traits, such as mental glands, but the species, otherwise, has little variation besides the amount of guanophores and white patterning on the skin (Acosta-Galvis and Gutierrez-Lamus 2012).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Colombia
Life History, Abundance, Activity, and Special Behaviors
This species is a slow moving and recognized as one of the smallest species found in Colombia (Acosta-Galvis and Gutierrez-Lamus 2012).
There is little known about these species besides, but it is assumed to a direct developer as that is a trait of the genus (Acosta-Galvis and Gutierrez-Lamus 2012).
Predators of the species are unknown and their food source/ prey is also unknown (Acosta-Galvis and Gutierrez-Lamus 2012).

PHYLOGENETIC RELATIONSHIPS:Based on morphological characters, B. guaneae is closely related to B. pandi and B. phalarosoma (Acosta-Galvis and Gutierrez-Lamus 2012)
The specific epithet, “guaneae”, alludes to the native Guanes who lived within the distribution range of the species. They inhabited the area since 600 B.C and in 1586 they almost disappeared after fighting with the Spanish. They currently live in Guane, a town of Santander in a small Indian area (Acosta-Galvis and Gutierrez-Lamus 2012).
