Opisthosoma with 22 (22–23) dorsal annuli, smooth, with three dorsal longitudinal ridges extending along opisthosoma; 51 (48–54) ventral annuli, with microtubercles becoming gradually more elongated posteriorly to ventral seta II (e).

Material examined

Thirty-six females and eight male specimens, from Artocarpus heterophyllus Lam. (Moraceae) , Recife , Pernambuco, Brazil, 08°01 ′ 07 ″ S, 34°56 ′ 41 ″ W, 2 December 2010, collected by A.C. Reis, on 10 microscope slides. Material 25 specimens (18 females and seven males, on eight microscope slides) deposited in the collection of the Laboratório de Acarologia, Departamento de Agronomia, Universidade Federal Rural de Pernambuco, Recife, PE, Brazil and 11 specimens (10 females and one male, on two microscope slides) also deposited in the collection of Embrapa Recursos Genéticos e Biotecnologia, Brasília, DF, Brazil. We had no access to the type material .

Relation to host

No visible damage.

Remarks

A line running between the bases of scapular setae and bearing various refringent bodies or granules was observed; these granules are individualized or clustered.
