Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Mollusca Gastropoda Littorinimorpha Hydrobiidae

Scientific Name: Iglica kleinzellensis Reischütz, 1981
Taxonomic Notes: This species was originally viewed as a subspecies of Iglica gratulabunda (Gloer 2002).  The shell form is variable, as shown by Gloer (2002, p. 142)

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2010
Date Assessed: 2010-01-19
Assessor(s): Haase, M. & Reischutz, P.
Reviewer(s): Fehér, Z., Seddon, M.B., Van Damme, D. & Cuttelod, A.
Justification:
Iglica kleinzellensis is known from a small area, where has only been found as dead-shells in the outflow springs from the Karst groundwaters. The species is believed to need clean water, and there is the possibility of pollution of the groundwaters from agricultural sources. These outflow springs are known to dry-up due to abstraction of the water sources (P. Reischutz pers.comm 2009), but it is not known to which extent these potential threats are impacting the species. Therefore the species is considered as Vulnerable D2. However, should the impact of these threats increase, the species would qualify for Endangered, B2 ab(iii).

Geographic Range [top]

Range Description:Iglica kleinzellensis is known from a small area and has only been found as dead-shells in the outflow of springs from karst groundwaters. This sites are springs north of Ortstrand, near Kleinzell im Halbachtal, Niederosterreich.  Gloer (2002) notes that in addition to the type locality, it is known from two other springs in the immediate vicinity near Kleinzell (Kalter Brunnen 500m s. of town) and a temporary karst spring at Gutenbach near to the Hisrchkogel. Sites lie in the valleys of Turnitz and Traisen (Haase pers, comm 1996).

Habitat and Ecology [top]

Habitat and Ecology:This species is known as dead shells from freshwater springs, and is presumed to live in the groundwater feeding the springs.
Systems:Freshwater
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: No trade in this species.

Threats [top]

Major Threat(s): The main threats are changes to the groundwater system, either through over abstraction of water (leading to drying of the outflow springs) or pollution of groundwater from agricultural sources.

Conservation Actions [top]

Conservation Actions: Iglica kleinzellensis is listed as Critically Endangered on the Austrian National Red List, as well as the Lower Austria List as A1.  Further research is required to know if the species is still extant in the groundwaters of the region, although sampling these sites is very difficult, and possibly only habitat monitoring will reveal changes to that would impact the species.
