Aulonastus pteroptochos  sp. nov.

( Figs. 4–5View FIGURE 4View FIGURE 5)

Description. FEMALE, holotype. Total body length 385 (385–430 in 6 paratypes). Gnathosoma  . Infracapitulum sparsely punctate. Stylophore 120 (115–125) long, basal part of its dorsum with longitudinal striae. Each medial branch of peritremes with 1 chambers, each lateral branch with 6 chambers. Idiosoma  . Propodonotal shield with concave anterior margin, punctate, bearing bases of setae ve, si and c 1. Length ratio of setae ve: si: se 1: 1: 6–6.2.

Hysteronotal shield well developed, fused to pygidial shield, punctate in posterior part. Setae f 2 2.7–3 times longer than f 1 and h 1. Setae ag 1 and ag 3 subequal in length, both pairs about twice as long as setae ag 2. Coxal fields I –II weakly sclerotised and striated, III –IV well sclerotised; all coxal field sparsely punctate. Setae 3 c 1.5–1.6 times longer than 3 b. Legs. Fan-like setae p’ and p” of tarsi III –IV with 6–7 tines. Setae tc”III –IV 1.8 times longer than tc’ III –IV. Lengths of setae: ve 20 (20), si 20 (20–25), se 120 (120–125), c 1 155 (155–165), c 2 120 (110–120), d 1 15 (15), d 2 120 (120–130), e 2 25 (25), f 1 20 (20), f 2 60 (55–60), h 1 20 (15–20), h 2 200 (200–205), ag 1 70 (70–75), ag 2 35 (30–40), ag 3 (70–85), tc’III – IV 20 (25), tc” III –IV 35 (35), 3 b 15 (15–20), 3 c 25 (25–30).

MALE. Unknown.

Type material. Female holotype, 6 female and 1 male paratypes from the Black-throated Huet-huet Pteroptochos  tarnii  (King) ( Passeriformes  : Rhinocryptidae  ); CHILE: Valdivia, 3949 'S 7314 'W, 28 November 1924, coll. Ohde.

Type material deposition. All type material is deposited in the AMU, except 1 female paratype in the ZSM.

Differential diagnosis. Aulonastus pteroptochos  sp. nov. is morphologically close to to A. euphagus Skoracki, Hendricks and Spicer, 2010  described from Euphagus  cyanocephalus (Wagler) ( Passeriformes  : Icteridae  ) in the United States ( Skoracki et al. 2010). In females of both species, the stylophore is striated; each medial branch of the peritremes has one chamber; the propodonotal shield is punctate; the hysteronotal shield is well developed and fused to the pygidial shield; setae h 2 are distinctly longer than f 2, and setae c 1 are slightly longer than se. The new species differs from A. euphagus  by the following features: in females of A. pteroptochos  , the infracapitulum is sparsely punctate; each lateral branch of the peritremes has six chambers; the hysteronotal shield is punctate in the posterior part; the length ratio of setae ag 1: ag 2 is 2: 1, and length of setae se is 120–125. In females of A. euphagus  , the infracapitulum is apunctate; each lateral branch of the peritremes has 4–5 chambers; the hysteronotal shield is apunctate in the posterior part; the length ratio of setae ag 1: ag 2 is 1.2–1.4: 1, and length of setae se is 140–145.

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.
