Conservation
This species was first collected by I. Payton and J. Marston from the Waiatoto Valley, S Westland in 1973. All the remaining records listed here are based on collections by P. Mayhill in the 1980s and one in 1992 from W of Lake Moeraki, near Haast, S Westland. One of the authors collected S. canaliculata from NE of Charleston, N Westland in 1992. We recommend continuing to rank S. canaliculata as ‘At Risk: Naturally Uncommon’, with the qualifiers of ‘Data Poor: Size and Trend’ and ‘Biologically Sparse’.
