Some noteworthy features of the chelicerae and subcapitulum of Phytoseiulus longipes Evans (Acari: Mesostigmata: Phytoseiidae), with observations on the preoral channel in the Phytoseiidae

The female chelicerae and subcapitular groove of Phytoseiulus longipes Evans are described; the presence of a large lobe on the fixed digit in P. longipes as well as in Euseius finlandicus (Ouds.) in relation to liquid feeding is discussed. The presence/absence of cuticular processes forming a "strainer mechanism" on the labrum and preoral channel is discussed in relation to the feeding habits among some Parasitina and Dermanyssina.
