Morphology of two Larinus Dejean (Coleoptera: Curculionidae) species introduced into North America for biological control of knapweeds

Levent Gültekin, Robert S. Anderson


The morphology of two introduced knapweed feeders Larinus obtusus Gyllenhal, 1835 and Larinus minutus Gyllenhal, 1835 is investigated. The external and internal morphological characters are described for both sexes. The most promising discriminative characters including male and female terminal segments and genitalia structure are illustrated.
