Scientific Name:

Phyllopetalia stictica

Species Authority:

Hagen in Selys, 1858

Common Name/s:

English

Unicorn Redspot

Assessment Information [top]

Red List Category & Criteria:

Data Deficient ver 3.1

Year Assessed:

2006

Assessor/s

von Ellenrieder, N.

Evaluator/s:

Clausnitzer, V. & Paulson, D. (Odonata Red List Authority)

Justification:
Known from more than ten locations and extent of occurrence more than 20,000 km², but habitat most likely fragmented and quality declining; information on current distribution and habitat requirements, population size and threats necessary to know if the species qualifies as LC or if it should be considered NT or VU.

History:

Geographic Range [top]

Range Description:	Occurs in central third of Chile, from Valparaiso Region south through Metropolitana, Maule, Bío-Bío, Araucania to De Los Lagos Region (von Ellenrieder 2005).
Countries:	Native: Chile

Population [top]

Population:	Although known from ten locations, the habitat of this species is fragmented and further research is needed to understand the global population.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Small forest streams; flight recorded as slow and close to water surface, following narrow streams within forest (Jurzitza 1989); feeding flight observed during late afternoon over pasture lands (Dunkle 1985). Flight period extends from October to February based on collection data. The description of the larva by Schmidt (1941), so far the only one known for the genus, was based on specimens collected at "Comudes", and was presumed to belong to that species by association with adults collected at the same locality. I was unable to find out the exact location of Comudes in Chile, but I still consider the identity of the described larvae as tentative, since Phyllopetalia apollo, P. pudu and P. stictica are sympatric and the described larvae could belong to any of these three species (von Ellenrieder 2005).
Systems:	Freshwater
