S. pundahis is very rare in Denmark, we have only two specimens, 

 a male and a female (Stæger's type-specimens) as far as known taken 

 on Amager at the border of a ditch; there seems to have been one 

 or a couple more specimens, as Zetterstedt metions two males and a 

 female. The species was detected by Stæger, and as Zetterstedt says : 

 "Stæger in litteris" the name is originally due to Stæger, as is also 

 the description in Zetterstedt II, 477. 



Geographical distribution: — Besides from Denmark the species 

 is only known from Sweden.
