A NEW TENTHREDINID
Published online by Cambridge University Press: 31 May 2012
Extract
Genus Synairema, Hartig.
This genus was detached from Tenthredo by Hartig in 1837, for an insect described in 1793 by Panzer, under the name of Tenthredo rubi, found in Germany, Sweden, France, Tyrol, &c. In 1849, Bremi described a new species found in Helvetia, which he named S. alpina. It has not yet been recorded as met with in America.
Synairema differs only from Tenthredo by its lanceolate cell, which is largely contracted in the middle, while in the last it is separated by a straight nervule.
