Taxonomy
Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Cyprinodontiformes Rivulidae
Taxon Name:ÊÊAnablepsoides speciosus (Fels & de Rham, 1981)
Synonym(s):
• Rivulus speciosus Fels & de Rham, 1981
Common Name(s):
• Spanish: pez anual
Taxonomic Source(s):
Eschmeyer, W.N. (ed.). 2014. Catalog of Fishes. Updated 3 January 2014. Available at:

Assessment Information
Red List Category & Criteria: Critically Endangered B2ab(iii,v) ver 3.1
Year Published: 2016
Date Assessed: April 24, 2014
Justification:
This species has a very restricted distribution (area of occupancy (AOO) = 9 km²) and it occurs at only
one location that is being affected by deforestation for livestock raising, which is causing a continuous
decline in the quality of its habitat due to erosion and sedimentation. The species is also being collected
for the ornamental trade, suggesting that there may be a continuous decline in the number of mature
individuals. Therefore, it is listed as Critically Endangered.
Geographic Range
Range Description:
This species is endemic to Peru where it is so far known only from its type locality in Quisto Cocha
(3°56'S, 72°24'W), 18 kilometres from Iquitos on the Iquitos-Nauta road (Fels and Rham 1981), in the
Amazon basin (Ortega et al. 2012). The elevation is approximately 100 m. The area of occupancy (AOO)
is estimated as 9 km² (calculated using a 3 x 3 km grid cell over the single locality where the species is
known from) and it occurs in a single location, based on the main threats to the species (capture for the
ornamental trade and erosion and sedimentation from livestock).
Country Occurrence:
Native: Peru

Population
There are no data on population size and trends for this species. It is not frequent. The capture of this
species for the ornamental trade is inferred to be causing continuous decline in the number of mature
individuals.
Current Population Trend:ÊÊUnknown
Habitat and Ecology (see Appendix for additional information)
This annual species inhabits small temporary ponds fed by small streams that may dry up in the dry
season. It feeds on aquatic invertebrates. It is assumed that the habitat quality of this species is
declining due to erosion and sedimentation from livestock raising.
Systems:ÊÊFreshwater
Use and Trade
This species is in the ornamental trade.
Threats (see Appendix for additional information)
The main threat to this species is the capture for ornamental trade. In addition, there is deforestation
for livestock raising in the area that is causing erosion and sedimentation.
Conservation Actions (see Appendix for additional information)
There are no conservation measures in place for this species. It is not present in protected areas.
Research is needed to better determine its distribution, population size and trends, sustainable harvest
levels and to assess the impact of the current threats on its population.
