In this section, we show an easy way for beginners to discriminate Japanese species. In this way, we focus on 15 species collected frequently in the past in Japan and on 9 species of morphological similarity.

In advance, prepare the slide specimens of adult females, and check whether each specimen is an adult female or not as below. Then, go to STEP 2

1. Count the dorsal setae. The specimen maybe a Japanese phytoseiid species if less than 22 pairs.

2. Check the shields (plates) on the ventral surface. The specimen maybe an adult female of a phytoseiid species if it has sternal, genital, and ventri-anal shields.

3. Check the spermathecae around the coxa of III and IV legs. The specimen must be an adult female if a spermatheca is observed at least at one side.

Inadequate specimens

4. The specimen may not be a phytoseiid species if it has 22 pairs or more.

5. The specimen maybe an adult male if it has sterno-genital and ventri-anal shields. The male specimen has a spermatodactyl on both chelicerae.

An exception

The ventri-anal shield is not clearly observed on the ventral surface of a species, Gynaeseius liturivorus.

Go to STEP 2 if the specimen is an adult female of phytoseiid species.
