A new Colombian species of gymnophthalmid lizard is described from Porce River piedmont, in the northern region of the Cordillera Central of Colombia. The new species is allocated in the Anadia bitaeniata group and represents the westernmost member of the group. This species is distinguished primarily by the sub-hexagonal dorsal scales, large quadrangular ventral scales, ten femoral pores per leg not separated by inter-pore scales in both sexes, and by a combination of several characteristic scale counts, hemipenial morphology and color pattern. The threatened status of the new species is discussed.

A new species of Monticalia with minute, ciliate leaves, radiate capitula, and eight involucral bracts is described from the northern Andes of Ecuador. It is a striking shrub that has been oddly overlooked until now. It grows in the highlands of Papallacta, a very humid páramo characterized by harboring many lagoons. Photographs of living plants of the new species and a related taxon are provided.

The genus Caloctenus Keyserling, 1877 comprises four species of small (3–7 mm) ground-dwelling spiders found in cloud forests and adjacent habitats of the northern Andes of South America, at elevations between 1800 to 2600 m (Silva 2004). All species apparently have a restricted geographic range and most are only known from the type locality. These spiders exhibit a cryptic coloration having a dark brown body with iridescent scales, sparse white plumose hairs and club-shaped red hairs, an ornamentation pattern that makes them indistinguishable from the leaf litter and hard to find. Recent attempts to find more caloctenine spiders in a Peruvian type locality were unsuccessful and it appears their populations, in general, are declining as fast as are their mossy and humid microhabitats.

Meriania juan-canoi, a new species endemic to the northern Andes in Colombia is described and illustrated. This new species belongs to the Brachycera group and can be distinguished from the other species by its apically rounded calyptra, completely free ovary and dimorphic stamens. The description of this new species from a relatively well collected area near a major road in southeastern of Medellín, Colombia, confirms our lack of knowledge on the vegetation of several Neotropical regions. Due to the intense agricultural activity in the area where this species grows and the small area where it occurs, we recommend a conservation classification of Critical Risk (CR).

A new species of Symphyogyna, S. caduciloba, is described, based on the combination of ascending growth form, deeply lobate thallus, variable lobe tips with a small, 1–2-celled apical tooth which is sometimes replaced by a slime papilla, and caducous thallus lobes. Relations with similar species are discussed and a key to the lobate species of Symphyogyna in Ecuador is presented.
