# Pristimantis taeniatus
## Taxonomy and Nomenclature
*Pristimantis taeniatus* was first described by Wilhelm Peters in 1873. It belongs to the genus *Pristimantis*, which is one of the most speciose genera of frogs, comprising hundreds of species primarily distributed in Central and South America. The genus is part of the family Strabomantidae, a group characterized by direct development, meaning their eggs hatch directly into miniature frogs without a free-living tadpole stage.
The specific epithet *taeniatus* derives from Latin, meaning „banded” or „striped,” referring to the species’ distinctive dorsal patterning.
## Description
### Morphology
*Pristimantis taeniatus* is a small to medium-sized frog, with adult snout-vent length typically ranging from 20 to 35 millimeters, though size can vary geographically. The species exhibits sexual dimorphism, with females generally larger than males.
The dorsal coloration is variable but often includes a base color ranging from brown to gray, overlaid with darker longitudinal stripes or bands, consistent with the species name. The ventral surface is usually lighter, often cream or pale yellow, sometimes with faint mottling. The skin texture is generally smooth to slightly granular, with some individuals exhibiting small tubercles on the dorsum.
The head is moderately broad with a rounded snout. The tympanum is visible but often partially obscured by skin. The fingers and toes lack webbing but have expanded digital pads that aid in climbing and gripping vegetation.
### Vocalization
Males produce advertisement calls during the breeding season to attract females. The call is typically a series of short, high-pitched notes repeated at regular intervals. The acoustic properties of the call can vary among populations, potentially serving as a mechanism for reproductive isolation.
## Distribution and Habitat
### Geographic Range
*Pristimantis taeniatus* is distributed across the northern Andes, primarily found in Colombia, Ecuador, and parts of Venezuela. Its range extends from low montane forests to higher elevation cloud forests, typically between 800 and 2,500 meters above sea level.
### Habitat Preferences
This species inhabits humid montane forests, including primary and secondary growth. It is predominantly terrestrial but can be found on low vegetation and leaf litter. The microhabitat selection includes moist leaf litter, fallen logs, and under stones, where humidity is maintained.
The species is adapted to environments with high humidity and stable temperatures, often associated with cloud forest ecosystems. It is sensitive to habitat disturbance, although it can tolerate some degree of habitat modification.
## Ecology and Behavior
### Diet
*Pristimantis taeniatus* is insectivorous, feeding primarily on small arthropods such as ants, beetles, and spiders. Foraging occurs mostly at night, with individuals actively searching through leaf litter and low vegetation.
### Reproduction
Reproduction in *Pristimantis taeniatus* follows the direct development reproductive mode characteristic of the genus. Females lay eggs in moist terrestrial microhabitats, such as under leaf litter or moss. The eggs develop directly into froglets, bypassing the aquatic tadpole stage, which allows the species to reproduce in habitats without standing water.
Breeding activity is often correlated with rainy seasons, when humidity is high, facilitating egg development and survival.
### Predators and Defense
Predators of *Pristimantis taeniatus* include snakes, birds, and small mammals. The species relies on camouflage provided by its dorsal coloration to avoid detection. When threatened, individuals may remain motionless or seek refuge under debris.
## Conservation Status
According to assessments by conservation organizations, *Pristimantis taeniatus* is currently classified as Least Concern due to its relatively wide distribution and presumed large population. However, ongoing threats include habitat loss from deforestation, agricultural expansion, and human settlement.
Conservation efforts focus on habitat protection, particularly in montane forest reserves and national parks within its range. Monitoring populations and habitat quality is essential to detect potential declines.
## Research and Importance
*Pristimantis taeniatus* serves as an important species for studying amphibian diversity, biogeography, and evolutionary biology in the Andes. Its direct development reproductive strategy provides insights into amphibian adaptation to terrestrial environments.
The species also contributes to ecosystem functioning by controlling insect populations and serving as prey for higher trophic levels.
