Abstract
Taxonomic studies on five species of Tenthredo Linnaeus were carried out of which two species are described and illustrated as new to scinece from the Indian subcontinent. The other three species, viz. Tenthredo occipitalis Malaise, Tenthredo salvizii (Malaise) and Tenthredo simlasensis (Cameron) are described and illustrate on a uniform systematic pattern. Key characters for Tenthredo maec sp. nov. include: ration of scape and pedicel as 5:3; post acellar are broader than long as 5:4; antennal segment three and four as 4:3 and four apical antennal segments somewhat compressed. The specific characters of Tenthredo pleurimpunctata sp. nov. are: frontal spot covering most of the frontal area but not touching eye margins; scape and pedicel as 5:3; antennal segment three and four as 3:2; mesosternum lacking thorns and post ocellar area almost quadrate.
