Type specimens. Holotype female from soil under fig plant, at Senuris, Fayoum governorate, June 2012; one paratype female from soil under P. e d ul i s, at Orman Botanical Garden, Giza governorate, June 2012; one paratype female from soil under L. indica  , at the Faculty of Agriculture Farm, Cairo University, Giza governorate, July 2012; one paratype male from soil under an apple tree, at Senuris, Fayoum governorate, October 2012, all collected by R.I.A. Abo-Shnaf. Holotype deposited at the mite collection of the Faculty of Agriculture, Cairo University, Giza governorate, Egypt; paratypes deposited at Departamento de Entomologia e Acarologia, Escola Superior de Agricultura “Luiz de Queiroz” ( ESALQ), Universidade de São Paulo ( USPAbout USP), Piracicaba, State of São Paulo, Brazil.

Etymology. The name fayoumensis  refers to Fayoum, the governorate where the holotype female and the paratype male were collected.

Remarks. Females of this new species are most similar to Typhlodromus (A.) balanites  ( El-Badry, 1967 b), T. (A.) bambusae ( Ehara, 1964)  , T. (A.) bergi ( Moraes & McMurtry, 1988)  , T. (A.) hartlandrowei ( Evans, 1958)  and T. (A.) transvaalensis ( Nesbitt, 1951)  . T. (A.) balanites  differs from the new species by having st 3 on sternal shield and the ventrianal shield with a pronounced constriction at the level of JV 2 (vase-shaped); T. (A.) bambusae  , by having a slightly shorter peritreme (extending slightly anteriad of z 2), st 3 and st 4 inserted on the unsclerotised cuticle and macrosetae sharp-tipped; T. (A.) bergi  , by having most dorsal idiosomal setae smooth, st 3 on sternal shield and ventrianal shield with four pairs of pre-anal setae; T. (A.) hartlandrowei  , by having st 3 on sternal shield and one pair of metapodal plates; T. (A.) transvaalensis  , by having most dorsal idiosomal setae distally knobbed and sternal shield with a distinct median lobe on posterior margin.
