A NEW CRYPTIC SPECIES OF TRICHOGRAMMA (HYMENOPTERA, TRICHOGRAMMATIDAE) FROM THE MOJAVE DESERT OF CALIFORNIA AS DETERMINED BY MORPHOLOGICAL,REPRODUCTIVE AND MOLECULAR-DATA

A new species of Trichogramma, T. kaykai, is described from the desert s of southern California where it is a common egg parasitoid of the ly caenid butterfly Apodemia mormo. The new species is closely related to T. deion, the most common Trichogramma in western North America. It i s distinguished from T. deion by morphological, allozymic and ITS2 seq uence differences; the two also appear to be reproductively incompatib le.
