Etymology.
Refers to its
type
locality, in
Colombia
.
Distribution and habitat.
This species was found in areas of Amazon forest,
Guaviare Department
and low Andes Region, Tumaco municipality, both in equatorial area of
Colombia
. These locations are situated respectively in Good’s biogeographic zone 26 and 28 of Neotropical region (
Good, 1974
). The climate of the area is “Af” tropical rain florest climate, characterized by high humidity (
Kottek et al., 2006
). The new species represents the first record of
Salina
with rectangular mucro from
Colombia
.
