Scientific Name: Libellula mariae Garrison, 1992

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
Assessor(s): Paulson, D. R.
Reviewer(s): Clausnitzer, V. & Kalkman, V. (Odonata Red List Authority)
Justification:
L. mariae is a moderately wide ranging species within a rather limited range in the mountains of Costa Rica and so far not found commonly anywhere, but not enough field work has been carried out in its range to have a good idea of its present status. Extremely unlikely in assessor’s opinion that such a large libellulid would have such a limited range, and its general rarity makes it likely it has been overlooked in similar habitats in large area of montane forest in Costa Rica, Panama, and perhaps Nicaragua and/or Colombia. Nevertheless, occurrence in cloud forest is already indicative of spotty distribution, and the species should be watched if possible with the hope that the number of locations (currently four) will increase.

Population [top]

Population:Details for L. mariae population numbers are not known at present although it is found in four locations.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:One male was found at a pool in a small swift, clear, sand- and rock-bottomed stream with grassy banks. Found breeding at a permanent root hole caused by tree fall in swampy area in primary forest. Also at a pool in a spring seep in secondary forest 5 km from tree fall site (W. Haber pers. comm. 2006).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): There is little data available to assess the threats to this species, however it is thought that deforestation could cause a problem in the future.

Conservation Actions [top]

Conservation Actions: One population of L. mariae occurs in Tapantí National Park and another in Monteverde Cloud Forest Preserve. Surveying for additional populations is needed.
