Zetzellia ampelae Johann and Ferla  Edit sp. nov.

( Fig. 8)

Description. FEMALE. Gnathosoma  Edit . Palp coxae with 1 spiniform setae; trochanter without setae; femur with 3 long and serrate setae, one of them more robust; genu with 1 long and serrate seta; tibia with 2 setae, 1 claw and 1 accessory claw slender; tarsus with 3 setae, 1 sensillum trifurcated and 2 solenidia ( Fig. 8 B). Infracapitulum with 2 pairs of slender setae and 2 pairs of adoral setae distally. Idiosoma  Edit . Oval outline. Dorsum: Prodorsal shield with 3 pairs of serrate setae, 1 pair of eyes and 1 pair of post-ocular bodies. Hysterosomal shield smooth with 4 pairs of setae. Setae c 2, d 2 and f inserted on small independent shields. Short podocephalic canal starting between the base of palps and leg I, extendig to the base of leg I. Venter: 3 pairs of slender setae between coxae, 1 a at level of coxa II, 3 a anterior to coxa III and 4 a at level of coxa IV. Setae ag 1 inserted on small shields before genital opening and setae ag 2 inserted laterally to genital opening, situated on separate shields ( Fig. 8 C). Genital region with 4 pairs of setae (g 1, ps 3, ps 2 and ps 1), with ps 3, ps 2, and ps 1 more robust and serrate. Setae g 1 reaching the base of setae ps 2. Leg I – IV setation ( Fig. 8 D). coxae 2 (1)- 1-2 - 2; trochanters 1 - 1 - 1 - 1; femora 5 - 4 - 2 - 2; genua 4 - 1 -0-0; tibiae 5 (1)- 5 (1)- 5 (1)- 5 (1); tarsi 12 (1)- 9 (1)- 7 (1)- 7.

Male. Unknown.

Measurements of this species are provided in Table 7.

Type material examined. CAS- 12 (MCN). Female holotype and 2 female paratypes from Boqueirão do Leão: holotype from V. labrusca, Bordeaux  Edit cultivar, 0 8 January 2007, coll. F. Diel; 1 female paratype with same data, 21 November 2006, coll. T.B. Horn; 1 female paratype with same data, 11 December 2006, coll. J.F. Silva. Type deposition. Holotype and all paratypes in MCN.

Differential diagnosis. The new species is similar to Zetzellia quasagistemas Hernandes and Feres, 2005  Edit regarding c 1 setae inserted on the hysterosomal shield. Zetzellia ampelae  Edit sp. nov. has ag 2 setae located on the individual shields lateral to the genital opening and two setae and two claws on the palptibiae, ve, sci and sce setae are 30 % longer than those in Z. quasagistemas  Edit ( Fig. 8 A). In Z. quasagistemas  Edit , ag 2 setae are located on the horseshoe-shaped shield that surrounds the genital opening and it has three setae, in addition to one claw on the palptibiae.

Etymology. The species name is derived from the Greek word Ampelos meaning “vine”.

Remark. It is not possible to associate the new species with phytophagous mites.
