Abstract

The two tetranychid genera Paraplonobia Wainstein and Neopetrobia Wainstein ( Trombidiformes : Tetranychidae ) are reported for the first time from Saudi Arabia. Three new species Paraplonobia ( Anaplonobia) arabica Mirza & Alatawi, sp. n., Paraplonobia ( Anaplonobia) haloxylonia Alatawi & Mirza, sp. n. and Paraplonobia ( Anaplonobia) tabukensis Kamran & Alatawi, sp. n. are described and illustrated based on adult females, collected from Prosopis juliflora (SW.) Dc. ( Fabaceae ) and Haloxylon salicornicum Bunge ( Amaranthaceae ) from two different regions of Saudi Arabia. Neopetrobia mcgregori (Pritchard and Baker) is redescribed and illustrated based on female collected from Cynodon dactylon L. ( Poaceae ).The diagnostic morphological features including leg chaetotaxy of all known species of the subgenus Anaplonobia is tabulated. A key to the world species of the genus Paraplonobia is also provided.
