Glossiphonia elegans ( Verrill 1872)

Common names: Brook leech or snail leech

General distribution: Holarctic ( Figures 2 A, 4A, Tables 1,2).

Newfoundland: Survey: Site 1 (CMNA 2006–0002), Site 10 (CMNA 2006–0005), Site 14 (CMNA 2006–0008), Site 17 (CMNA 2006–0012), and Site 18 (CMNA 2006–0013); Museum specimens: CMNA 1987–0467; Literature: Pawlowski (1948) as Glossiphonia complanata at Deer Lake; Pickavance (1971) as Glossiphonia sp. in Rennies River, St. John’s; Davies (1973) as G. complanata at Rocky Harbour.

The record by Pickavance is questionable since Glossiphonia heteroclita was a name sometimes used for Alboglossiphonia heteroclita .
