Type material — Female holotype, 36 female and 13 male paratypes, from Delonix regia (Bojer ex. Hook.) Raf. (Fabaceae), Brasília, Distrito Federal, Brazil, 15°47'S and 47°55'W, 6th September 2005, collected by L. Calvoso Miranda, on 10 slides, in the collection of Laboratório de Quarentena Vegetal, Embrapa Recursos Genéticos e Biotecnologia, Brasilia, DF, Brazil and paratypes in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo, ESALQ, Piracicaba, São Paulo, Brazil.
Relation to host — Mites are vagrants, causing no apparent damage.
Etymology — The specific designation, fenestratus, is derived from the Latin fenestra, window, and refers to the prodorsal shield central design.
Remarks — The pointed anterior lobe of the n. sp. resembles that of several other eriophyids in the genus Aculops Keifer, 1966, such as Aculops bolusanthi Meyer & Ueckermann, 1990 and Aculpos acaciae (Ryke & Meyer, 1960). However, the new species is strikingly distinct in the coxal ornamentation, being ornamented on coxae I and smooth on coxae II. In the other known species both coxae are either ornamented or smooth.
