Reis, 08° 01 ′ 07'' S, 34°56 ′ 41'' W, on six microscope slides. Holotype and paratypes (30 specimens, 20 females and 10 males, on six microscope slides) deposited in the collection of the Laboratório de Acarologia , Departamento de Agronomia, Universidade Federal Rural de Pernambuco, Recife, PE, Brazil . Paratypes (56 specimens, 40 females and 16 males, on 11 microscope slides) also deposited in the collection of Embrapa Recursos Genéticos e Biotecnologia, Brasília, DF, Brazil .

Relation to host

No symptoms seen.

Etymology

The specific designation “hibiscus” refers to Hibiscus, the host plant genus. It was coined by apposition of the tree genus to the mite genus.
