Assessment Rationale:

Dinotrema azoricum is an endemic species of the Azores, Portugal. It is known only from the holotype, collected on Sao Miguel in 1938, in a (currently) highly disturbed area. From the historical data, it potentially has a very small Extent of Occurrence (16 km2) and Area of Occupancy (16 km2). This species has possibly declined in the past as a result of human activity, but the present situation of this species needs to be further assessed and further research is needed into its population, distribution, threats, ecology and life history. Conservation of native vegetation could potentially aid this species' conservation. Based upon the unknown distribution, threats and ecology, this species is assessed as Data Deficient (DD). 

Geographic Range:

This species is known only from the holotype, collected on Sao Miguel island in 1938. Its location, Furnas, has been under high anthropogenic disturbance for the last decades. Based on the data from the 1938 expedition of Frey, Stora and Cedercreutz, the Extent of Occurrence (EOO) would be ca. 16 km² and the Area of Occupancy (AOO) would be ca. 16 km². There is no recent information regarding the distribution of this species.

Population:

Current Population Trend: Unknown 

Habitat and Ecology

The ecology and traits of this species are unknown. Other braconid wasps from the subfamily Alysiinae, tribe Alysiini are mostly solitary koinobionts. All species are endoparasitoids of Cyclorrhapha (Diptera) larvae (Goulet and Huber 1993). Many species from the genus Dinotrema are parasitoids of Phoridae (Diptera) in mushrooms (van Achterberg 1988). This species was collected in a disturbed area, in the vicinity of hotsprings.

Systems: Terrestrial 

Major Threat(s):

A lack of information regarding the present status of this species precludes an assessment of potential threats. Nevertheless, the area where the holotype was collected is highly disturbed by human presence, and therefore it could be assumed that past and present human disturbance and land use changes, together with habitat degradation caused by invasive species might have affected this species. 

Conservation Actions

The species is not protected by regional law. Conservation of native vegetation could potentially aid this species' conservation. Further research is needed into its population, distribution, threats, ecology and life history and hosts. Historically, this species was present in one area that is currently highly disturbed, but included in the Natural Park of S. Miguel.
