| abstract | Neoparaphytoseius Chant & McMurtry is a genus in the family Phytoseiidae, subfamily Amblyseiinae. The genus includes only two known species from Brazil and Peru, and the third is described here. Neoparaphytoseius caatinga n. sp. is described from the Caatinga biome of Alagoas State, where it was found on Croton blanchetianus Baill (Euphorbiaceae). The new species is compared with the closely related species, Neoparaphytoseius charapa Jiménez, McMurtry & Moraes, and N. sooretamus (El-Banhawy). An identification key for the species of this genus is provided, based on the examination of the type specimens. |
