Specimen notes
Three specimens of Potamopyrgus antipodarum were uploaded in this project (Snail 1-3). Snail 1 was short and wide, snail 3 narrow and elongate, and snail 2 had intermediary shell shape. Snail 1 was collected from a circa 8 m-wide river in the Kaniwhaniwha reserve in the Waikato region on New Zealand’s North Island (S 37° 55′ 12.8", E 175° 4’ 52.9") the 17th of February 2016; snail 2 from Lake Kiessee, near Jarmen in Mecklenburg-Western Pomerania in NE Germany (N 53° 55′ 44.5", E 13° 18’ 60.0") in June 2017; and snail 3 from a ca. 1 m-wide river in the northern West Coast region of New Zealand’s South island (S 42° 2′ 9.3", E 171° 23’ 21.1") on the 11th of March 2016. All snails were fixed on site in 70% ethanol.
