Range Description

This species is a widespread palearctic species present through much of Europe and into north Asia.

In Europe it is recorded from Norway, Sweden, Denmark (mainland), Finland, Estonia, Latvia, Lithuania, Poland, Republic of Ireland (Eire), Great Britain (UK), Northern Ireland (UK), Netherlands, Belgium, Luxembourg, France (mainland), Germany, Switzerland, Austria, Czech Republic, Slovakia, Hungary, Italy (mainland), Sardinia (Italy), Bulgaria, Romania, Balearic Islands (Spain), Spain (mainland), Portugal (mainland), Albania, the former Yugoslav Republic of Macedonia, Slovenia, Croatia, Montenegro, Bosnia and Herzegovina, Ukraine, and Greece (including Andikíthira Island, Evvia Island, Ionian Islands, Samothráki Island, Northern Sporades Islands, and Thásos Island).

In Africa Van Damme (2010) noted it was recorded in Algeria in the 19th century but this location is now highly populated and polluted so he believed it to be extirpated in northern Africa. Recent research by Glöer & Bouzid (2013) have relocated the species at Lac Tonga, a Ramsar site in Algeria, and the records has been confirmed by dissection, showing the species survives in Algeria.

It is recorded from Egypt but there are no recent records Van Damme (2010). In lower Egypt it was recorded from Fayoum, Lake Qaron (Gardner 1932) and upper Egypt at Kom Ombo; it is now extinct from these locations (original records possibly came from tombs or temples).

The records from the West and SW Asian parts of the range have not been confirmed anatomically, but are currently assigned to Radix auricularia, although Neubert (2012, pers. comm.) expresses some doubt about the Saudi Arabian records. These records also include Israel, Lebanon, Oman, Yemen, Iran and Iraq (Glöer and Pesic (2012) and possibly Jordan and Syria.

In Asia the species is recorded from Afghanistan, Bahrain, India (Maharashtra, Uttarakhand, Himachal Pradesh and Jammu and Kashmir states, and is likely to be present in further states), Moldova, Russia (including Kaliningrad), Ukraine and Yemen. It is distributed widely in China (including Heilongjiang, Jilin, Liaoning, Neimenggu, Hebei, Henan, Shandong, Xixi, and Shanxi, Gansu, Qinghai, Xinjiang, Xizang, Anhui, Jiangsu, Zhejiang, Jiangxi, Hubei, Hunan, Fujian, Guangdong, Sichuan and Yunnan provinces; Liu et al. 1979). There are also records from the Mekong drainage in Indochina (Thailand, Lao PDR, Cambodia and Viet Nam), Nepal and Bangladesh, and the species can be expected in Myanmar.

The species is introduced throughout the United States and can be expected to have been introduced elsewhere.
