Synonym/s: Elapomorphus punctatus Lema, 1979 Elapomorphus tricolor Duméril, Bibron & Duméril, 1854 Phalotris punctatus (Lema, 1979)

Taxonomic Notes:

After a comparison of the type of Phalotris tricolor and P. punctatus, Lema et al. (2005) concluded that both names referred to a single species.

Assessment Information

Red List Category & Criteria:

Least Concern ver 3.1

Year Published: 2010 Assessor/s: Cruz, F. & Nogueira, C. Reviewer/s: Böhm, M., Collen, B. & Ram, M. (Sampled Red List Index Coordinating Team)

Contributor/s: De Silva, R., Milligan, H.T., Wearn, O.R., Wren, S., Zamin, T., Sears, J., Wilson, P., Lewis, S., Lintott, P. & Powney, G.

Justification: Phalotris tricolor has been assessed as Least Concern. This species has a relatively wide distribution throughout Argentina and although this species is likely to be impacted by habitat loss and degradation in parts of its range, it can inhabit a variety of habitats.

Geographic Range

Range Description:

This species is found in Argentina, from Misiones in the northeast to Mendoza in the southwest (Lema 1978), and from Bolivia, Paraguay, and Parana State in Brazil (Lema et al. 2005).

Countries: Native: Argentina (Catamarca, Córdoba, Mendoza, Misiones, Salta)

Population

Population: There is no population information available for this species. Population Trend: Unknown

Habitat and Ecology

Habitat and Ecology:

This species is found in humid and arid Chaco habitat. However, it has also been collected at a study site highly degraded by deforestation and overgrazing (Leynaud and Bucher 2005).

Systems: Terrestrial

Threats

Major Threat(s):

In parts of its range it is likely that this species is impacted by habitat loss and degradation. Much of the Chaco habitat of South America is in various stages of alteration due to grazing of goats and cattle and this threat is reported to be most extensive in Argentina (WWF 2001a). The humid Chaco habitat of South America is reported to be relatively untouched, however, it is beginning to feel the pressures of human development (WWF 2001b). At present these threats are localized threats only and are not likely to be causing the species to suffer significant population declines.

Conservation Actions

Conservation Actions:

There are no species-specific conservation measures in place, or needed, for this species.

Liolaemus capillitas

Taxonomy

Kingdom Phylum Class Order Family ANIMALIA CHORDATAREPTILIA SQUAMATATROPIDURIDAE Scientific Name: Liolaemus capillitasSpecies Authority:Hulse, 1979 Common Name/s:

English – Hulse's Tree Iguana

Assessment Information

Red List Category & Criteria:

Least Concern ver 3.1

Year Published: 2010 Assessor/s: Espinoza, R. & Cruz, F.B. Reviewer/s: Böhm, M., Collen, B. & Ram, M. (Sampled Red List Index Coordinating Team)

Contributor/s: De Silva, R., Milligan, H.T., Wearn, O.R., Wren, S., Zamin, T., Sears, J., Wilson, P., Lewis, S., Lintott, P. & Powney, G.

Justification: Liolaemus capillitas is listed as Least Concern. Despite having a relatively small distribution of less than 1,000 km², the areas of suitable habitat where this species is found experience minimal utilization by humans, and are therefore unlikely to be experiencing habitat degradation, and the species is consequently unlikely to be experiencing significant population declines.

Geographic Range

Hulse's Tree Iguana

Range Description:

This species is found in a small region of the Cuesta de Minas Capillitas, Catamarca, and probably into Tucumán province, Argentina, although this has not been confirmed. It has a distributional area of 948 km², and is found between 2,500 and 3,900 m above sea level.

Countries: Native: Argentina (Catamarca)

Range Map: Click here to open the map viewer and explore range.

Population

Population: There are no population data currently available for this species. Population Trend: Unknown

Habitat and Ecology

Habitat and Ecology:

This species is omnivorous and is found on steep rocky hillsides covered with bunchgrass, scattered low shrubs and small cacti. Within this habitat the species is restricted to rocky cliff faces and exposed road cuts. A large part of its diet consists of ants (R. Espinoza pers. comm. 2010).

Systems: Terrestrial

Threats

Major Threat(s):

Due to this species inhabiting hillside cliffs, there are no major threats to this species. Although there are livestock in the area, the locals tend to graze them along the roads or in the flatter areas near the top of the mountain where this species does not occur (R. Espinoza pers. comm. 2010). There has been a mine in the area of the mountain top for over 100 years; however, this probably does not constitute an immediate threat to this species (R. Espinoza pers. comm. 2010).

Conservation Actions

Conservation Actions:

There are currently no conservation measures in place for this species. More research is needed into the distribution of this species.

Contributor/s: De Silva, R., Milligan, H.T., Wearn, O.R., Wren, S., Zamin, T., Sears, J., Wilson, P., Lewis, S., Lintott, P. & Powney, G.

Justification: Lioloaemus chaltin is listed as Data Deficient. It has a relatively large distribution in Argentina and Bolivia, and further surveys may find new localities in more regions; however it is a poorly known species, its population and distribution status is unknown, and it is suffering from declines in the quality of its habitat due to overgrazing by domestic livestock. More research is needed into the threats of this species, and population monitoring is necessary before a more accurate conservation assessment can be made.

Systems: Terrestrial

Threats

Major Threat(s):

Overgrazing by domestic animals and collection of woody material for firewood are both having a detrimental effect on the habitat of this species.

Conservation Actions

Conservation Actions:

There are currently no conservation measures in place for this species. More research is needed into the threats to this species and monitoring of population trends is necessary.
