Abstract
The shape and dimensions of the spermathecae are taxonomically important ch aracteristics in phytoseiid mites. In experiments with Neoseiulus californi cus (McGregor) and Typhlodromus pyri Scheuten, the shape of the cervix of t he spermatheca changed considerably and its diameter was increased by 42-49 % when mites were flattened, compared to being mounted with 140 mum spacers underneath the coverslips. Dimensions of the dorsal shield were also affec ted by flattening, increasing by 3-5%.
