Vitrella gratulabunda A.J. Wagner, 1910
|Taxonomic Notes:||Haase (1995) considered this species to be a 'problematic taxa' known from few specimens all taken from a 'poorly defined locality'.|

Iglica gratulabunda is endemic to Austria. It was originally considered to be possibly Extinct (Wells & Chatfield 1992, IUCN 1994). Haase (1995) pointed out that further taxonomic research should also be undertaken, as the species is currently based on few specimens, and he recommended listing as Data Deficient in the 1996 Red List. However in a precautionary approach, the 2008 Austrian Red List has maintained this species as Critically Endangered. Given that the species is difficult to sample, as it is probably restricted to groundwaters, an assessment of Critically Endangered (Possibly Extinct) B2ab(iii) would be appropriate for the species until more survey efforts can demonstrate extinction and a taxonomic review confirms the species' status.

There is no population information available for this species.
|Habitat and Ecology:||
Iglica gratulabunda is recorded from floodline debris within freshwater rivers and is most probably present in subterranean waters, like other representatives of this genus.
It is unknown whether this species is being impacted upon by threat processes.
Further research is needed to confirm its presence and range, given the nature of the record, as it is currently only known from one location and with a second pre-1950 location. However, as the shells were retrieved from floodline debris, flushed from karst fissures it is difficult to establish population trends or range. The abstraction of groundwater water may pose a threat as this could cause the loss of the species' habitats. Further research is needed to confirm its presence and range, given the nature of the records. As it has been previously listed, it is maintained at the national assessment on a precautionary basis, rather than listing as Data deficient. There are no species-specific conservation measures in place for this species. In the past, this species has been classified as Possibly Extinct (IUCN 1994). Further research is recommended to ascertain whether this species still exists, and if it does then to clarify the extent of its distribution and identify any threat processes impacting upon it.
