->Range: Data for this biogeographic region does not allow defining a credible range, so no value is presented. ||
->Population: The species was only given for this biogeographical region in the period of the last report, with no information prior to 2007. ||
->HabInfo: The species uses habitats with specific characteristics, of good quality, these rare habitats. It is preferentially associated with small water courses, of moderate but permanent current, shallow watercourses of clear and well-oxygenated waters.

The data come from localized works and occasional personal communications, and there is no systematic prospecting of the species. Only in mid-2018, as part of the Red List of Invertebrates project, did systematic exploration work begin, with particular focus on classified areas, but the results of which will only be reflected in the next report.

The project "Red List for Terrestrial and Freshwater Invertebrate groups in mainland Portugal" started in mid-2018. This operation will be carried out over 3 years, covering the entire national territory of the continent, with particular focus on Sites of Community Importance (SCI)and on terrestrial and freshwater invertebrate species belonging to the annexes of the Habitats Directive but the results will only be reflected in the next report.
The main objectives of this project are:
(a) assess the conservation status, according to IUCN criteria, of species for some terrestrial and freshwater invertebrate taxonomic groups in mainland Portugal;
(b) to fill knowledge gaps in terrestrial and freshwater invertebrate species protected by the Habitats Directive to enable conservation status to be assessed under that Directive;
c) to elaborate and publish the Red List of Terrestrial and Freshwater Invertebrate groups of mainland Portugal in physical and digital support;
d) create a websig platform for storing information, publishing and disseminating results.

Information provided in the field 2.8.2: Reported additionnal information: ||
->Range: The current range surface area calculation does not represent the real range surface area. Change in availability of underpinning mapping data has resulted in an apparent decrease in range area compared to 2013, but this is not due to genuine change. Expert opinion considers the trend in range to be stable. The real range surface area is considered to be the range in 2013 - 4,140.73km2. The FRR in 2013 was 3,941km2. The FRR has been changed to an operator 'approximately equal to current' to reflect this. For further information see the 2019 Article 17 UK Approach document. ||
->Population: The short term trend direction is considered to be 'decreasing ≤1% (one percent or less) per year on average'. This relates to declines in Wales within all four SACs and the loss of the population at Sluxton Farm, Whitemoor. Remedial works have been initiated on three of the SACs to address these declines but may not be on the necessary scale to reverse current trends. ||
->HabInfo: The sufficiency of the quantity and quality of habitat for the species varies across the distribution of the species, with insufficiency reported in Wales. ||
->Future: Future trend of Range is Negative - decreasing <=1% (one percent or less) per year on average; Future trend of Population is Negative - decreasing <=1% (one percent or less) per year on average; and Future trend of Habitat for the species is Negative - slight/moderate deterioration. For further information on how future trends inform the Future Prospects conclusion see the 2019 Article 17 UK Approach document. ||
->Conclusion: Conclusion on Range reached because: (i) the short-term trend direction in Range surface area is stable; and (ii) the current Range surface area is approximately equal to the Favourable Reference Range.
Conclusion on Population reached because: (i) the short-term trend direction in Population size is decreasing by 1% per year or less; and (ii) the current Population size is not more than 25% below the Favourable Reference Population.
Conclusion on Habitat for the species reached because: (i) the area of occupied and unoccupied habitat is not sufficiently large and (ii) the habitat quality is not adequate for the long-term survival of the species; and (iii) the short-term trend in area and quality of occupied habitat is decreasing.
Conclusion on Future prospects reached because: (i) the Future prospects for Range are poor; (ii) the Future prospects for Population are poor; and (iii) the Future prospects for Habitat for the species are poor.
Overall assessment of Conservation Status is Unfavourable-inadequate because three of the conclusions are Unfavourable-inadequate.
Overall trend in Conservation Status is based on the combination of the short-term trends for Range - stable, Population - decreasing, and Habitat for the species - decreasing.
Overall assessment of Conservation Status has not changed since 2013.
Overall trend in Conservation Status has not changed since 2013.

->Range: Range area: Based on single known population.
Short-term trend: The species is known from a single site, although other sites are regularly targeted by field surveys. The area reported in 2013 is larger due to the consideration of two single individuals, vagrants. The short-term trend is therefore considered as stable. ||
->Population: Population size: the species is known from a single site. Targeted monitoring failed to observe the species in other sites.
Short-term trend: yearly counts of individuals suggest a stable population size. ||
->HabInfo: The species is found in a single stream.
The monitoring of the species includes the regular search of other sites suitable for the species. Based on expert opinion on the field, the availability of other suitable sites is very low. ||
->Future: The availability of area and quality habitat for the species is low so that the future prospect to enlarge the range is bad. The current population doing well but is highly isolated and exposed to threats from upstream. An IAS (Pacifastacus leniusculus) recently colonized the stream. This IAS is not known to be easily eradicated.
The upstream area is occupied by crops with intensive agriculture. In addition, a large liquid manure tank is located at less than 150m upstream. ||
->Conclusion: Luxembourg is located on the northern distribution limit of the species. The species has never been much more abundant than currently known. ||

->HabInfo: The specificity of habitat requirements, combined with a reduced dispersibility, makes the species particularly sensitive to destruction and fragmentation of its preferred habitat.
The construction of some dams in the area of occurrence of the species (Sabor, Tâmega) is certainly responsible for the reduction of available habitat. ||
