Assessment Rationale:

Hidryta azorica is a potentially endemic species of theAzores (Portugal) known only from the holotype and for which there is no precise indication of island of occurrence, while it has been suggested that Hidryta atlantica might be a melanic form of H. sordida, a widespread European species. It possibly has a very small Extent of Occurrence (EOO = 4 km²) and Area of Occupancy (AOO = 4 km²). Based upon the unknown distribution and ecology, this species is assessed as Data Deficient (DD). 

Geographic Range:

This species is only known from the holotype, Hidryta atlantica was described from the Azores, but without indication of the island of occurrence. It was never found after its description and consequently there is no precise indication of its location. Schwartz (2005) puts forward the possibility that Hidryta atlantica might be a melanic form of H. sordida, a widespread European species.

Population:

There are no available data on the population size and trend of this species.

Current Population Trend: Unknown 

Habitat and Ecology

The ecology and traits of this species are unknown. Most species belonging the the Cryptini tribe of the Cryptinae family are idiobiont ectoparasitoids of Holometabola pupae or pre-pupae, while some are koinobionts or endoparasitoids. Some species also parasitise the egg masses of Araneae and Pseudoscorpiones (Goulet and Huber 1993).

Systems: Terrestrial 

Major Threat(s):

A lack of information regarding the island or habitat where the holotype was collected or regarding the present status of this species precludes an assessment of potential threats.

Conservation Actions

The species is not protected by regional law. Further research is needed into its ecology and life history in order to find extant specimens. Schwartz (2005) puts forward the possibility that Hidryta atlantica might be a melanic form of H. sordida, a widespread European species; so further taxonomic work is required.
