Are distances between landmark setal pairs on dorsal shield in Paraphytoseius species (Acari: Phytoseiidae) of any taxonomic value?

It was observed that the transverse distances between the landmark setal pairs j1-j1, j3-j3, s4-s4, Z4-Z4, and Z5-Z5 and the vertical distances between the pairs j3-s4, s4-Z4, and z4-Z5 on the dorsal shield were much less in Paraphytoseius cracentis (Corpuz and Rimando, 1966) and much higher in Paraphytoseius orientalis (Narayanan, Kaur and Ghai, 1960). However, the vertical distance between j1-j3, that were located closer to each other than other pairs, were in variation range of each other in these 2 species. Some of these measurements, especially transverse distance between s4-s4 and vertical distance between s4-Z4, may be of additional taxonomic value. Therefore, study of these features in other species of Paraphytoseius and Phytoseiidae is suggested to see if such studies are useful.
