Type material . Female holotype , 26 females , two males , one deutonymph and two protonymph paratypes on unidentified Asteraceae ; four females , one male on Marcetia velutina (Melastomataceae) ; pedestrian grasslands, Rampa do Caim, Igatú, Chapada Diamantina, 12º53’31”S , 41º19’34”W , 762 m asl; 17 January 2012 . One female, one deutonymph on Panicum sp. (Poaceae) ; pedestrian grasslands, Mucugê, Chapada Diamantina, 12º53’49”S , 41º18’58”W , 1125 m asl; 19 January 2012 . Female holotype and other paratypes deposited in the Mite collection of the ESALQ-USP (Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo , Piracicaba, State of São Paulo , Brazil ). Other specimens in the Instituto Agroforestal Mediterráneo, Universitat Politècnica de València , Spain and the Mite collection of the Centre de Biologie pour la Gestion des Populations, INRAE , Montferrier sur Lez, France . Diagnosis. Female dorsal shield suboval, attenuated between setae s4 and Z1 ; surface distinctly imbricate. Dorsal setae smooth and pointed, except Z5 barbed. Setae j3 twice as long as j1 ; setae j5 0.8 times as long as j4 ; setae r3 1.5 times as long as R1 ; setae S2 , Z4 and Z5 similar in length. Dorsal adenotaxy reduced, with two pairs of dorsal solenostomes ( gd4 , gd6 ); poroidotaxy with the complement of sixteen poroids. Peritremes broad (8 µm wide), reaching the space between setae j1–j3 . Sternal shield striated longitudinally, with three pairs of setae; setae st4 on piriform plates placed close to the posterolateral projections of sternal shield. Ventrianal shield pentagonal, with laterals concave, narrower at the level of pre-anal pores; transversally striated in the anterior part, almost smooth posteriorly; three pairs of pre-anal setae; pre-anal pores punctiform, well separated each other (42–55), posterior or posteroantiaxial to setae JV2 . Atrium of the spermatheca globose and oval-shaped, longitudinally forked, almost as wide as base of calyx; calyx subconical, 10–12 long, 9–10 wide at the junction with the vesicle. Cheliceral fixed digit with three subapical teeth; movable digit with one small denticle, difficult to discern in some females. Genu II with eight setae (2 2/0, 2/1 1); one short (25–29), curved and pointed macroseta on basitarsus IV. Male spermatodactyl T-shaped (15 long); ventrianal shield striated, forming several cells on the anterior part; six pairs of pre-anal setae; pre-anal pores punctiform. Same dorsal adenotaxy, cheliceral dentition and leg setation than in female.
