Abstract

The genus Neoseiulus Hughes, 1948 is one of the largest genera in Phytoseiidae and contains more than 364 valid species in the world. In this paper, a new species N. setarius Ma, Meng & Fan, sp. nov. is described based on both adult female and male specimens collected from Setaria viridis (L.) Beauv. (Gramineae), in Inner Mongolia of China. The adult females of the new species are characterized by having a fully reticulated dorsal shield, barbed Z5, bell-shaped spermathecal calyx with a short basal stalk. Furthermore, seta R1 is off dorsal idiosomal shield in adult males.
