Prelorryia labrusca sp. nov. Silva, Cunha & Ferla

( Fig. 7 A–C)

Female (n = 1). Dimensions: length of idiosoma 240 and width 185.

Dorsum ( Fig. 7 A)—Prodorsum recurved, 10 pairs of dorsal setae (lacking ro); setae la and ex smooth, c1, c2, d1, e1, f1, f2, h1 slightly serrated and h2 smooth, slender. Trichobothrium (sci) whip-like, smooth. Setal measurements as follows: la 14, bo 55, ex 50, c1 17, c2 15, d1 12, e1 14, f1 13, f2 12, h1 16, h2 45 and ps1 absent. Body covered with striations.

Venter ( Fig. 7 B)—Anogenital area with four pairs of genital, four pairs of aggenital and ps 2 in anal region 22. Epimeral formula: 3-1-4-2.

Gnathosoma — Gnathosoma prominent. Setal pattern of palp (tarsus—genu): 5-2-2. Tarsus with seta p' ζ slightly cleft distally. Cheliceral stilettos length 20; length of palp 55.

Legs ( Fig. 7 C)—Length of legs I–IV as follows: leg I 105, leg II 90, leg III 105 and leg IV 102. All legs with two claws and a hairy empodium, empodial hooks absent. Solenidion (ωI) and (ωII) on tarsus I long, longer than half width of tarsus. Tibia II without solenidion (ȹ). Leg setal formulae as follows (tarsus—trochanter): Leg I: 8 (1ω)-4(1k)-1-4-1; Leg II: 6(1ω)-2-0-3-0; Leg III: 5-2-0-2-0; Leg IV: 5-2-0-0-0.

Male: Not found.

Differential diagnosis. The new species belongs to the genus Prelorryia by lacking setae on genua II, III and IV, and lacking solenidia (ȹ) on tibia I. This genus was previously monospecific, with only Prelorryia indonesiensis ( Baker, 1968) . Prelorryia labrusca sp. nov. is distinguished from P. indonesiensis by having a completely striate body, prodorsum lacking seta ro, setae h2 smooth and slender, tibia I with four setae, and the solenidion of tarsus I longer than half the width of the tarsus.

Etymology. This species name refers to the host plant V. labrusca .

Material examined. Brazil: Holotype female collected from Vitis labrusca (Bordeaux variety), Boqueirão do Leão County, State of Rio Grande do Sul, 21/XI/2006, coll. Horn, T.B. Deposited at Entomologia, Fitopatologia e Zoologia Agrícola Department, Escola Superior de Agricultura “Luiz de Queiroz” ( ESALQ), Universidade de São Paulo, Piracicaba, São Paulo State, Brazil.
