| abstract | A new species of the neotenic flat mite genus Larvacarus Baker and Pritchard, 1952 (Acariformes: Tetranychoidea: Tenuipalpidae), Larvacarus iranicus sp. nov., is described from females collected from Astragalus sp. (Fabaceae) in Iran (Kerman Province). This is the second report of this genus in the world. The relationships of Larvacarus with other flat mite genera, including the other larviform species in the genera Raoiellana Baker and Tuttle, 1972 and Phytoptipalpus Trägårdh, 1904 are discussed. |
