Aulonastus henicorhina Sikora and Skoracki  sp. nov.

( Figs. 7–10View FIGURES 7 – 10)

Description. FEMALE (holotype, 5 paratypes). Total body length 430 (410–435). Gnathosoma  . Infracapitulum and stylophore apunctate. Each medial branch of peritremes with 2 chambers, each lateral branch with 4–5 chambers. Length of stylophore and movable cheliceral digit 115 (115) and 80 (80), respectively. Idiosoma  . Propodonotal shield rectangular in shape, bearing bases of setae ve, si, se and c 1, sparsely punctate near bases of setae ve and si, Setae se and c 1 situated at same transverse level. Length ratio of setae ve: si 1: 1. Setae c 1 1.1–1.2 times longer than se. Length ratio of setae d 2: c 1 1: 1.1–1.2. Hysteronotal shield fused to pygidial shield, well sclerotized, apunctate, bases of setae d 1 and e 2 situates near this shield. Setae f 2 about 3 times as long as f 1. Setae h 2 3.5–3.7 times longer than f 2. Length ratio of setae ag 1:ag 2:ag 3 1.1–1.3: 1: 1.6–2.1. Genital plate absent. Both pairs of genital setae subequal in length. All coxal fields sparsely punctate. Legs. Fan-like setae p’ and p” of legs III and IV with 5 tines. Lengths of setae: ve (15), si (20), se 145 (135–145), c 1 (155–165), c 2 125, d 1 20 (20–25), d 2 135 (135–150), e 2 20 (20–25), f 1 20 (20), f 2 (60–65), h 1 20 (20), h 2 210 (210–225), ps 1 15 (15), g 1 and g 2 25 (25–30), ag 1 (50– 55), ag 2 40 (40–50), ag 3 85 (80–90).

MALE. Unknown.

Type material. Female holotype and paratypes: 5 females, 8 nymphs, 2 larvae and 3 eggs from quill of body feather of Henicorhina  leucosticta (Cabanis); ECUADOR, near Quito, coll. R. Olalla. Mites removed by M. Skoracki.

Type deposition. All type material is deposited in the AMU (AMU–SYR. 350), except 1 female paratype in the ZISPAbout ZISP ( ZISPAbout ZISP AVB 011- 2908 -003) and 1 female paratype in the ZSMAbout ZSM ( ZSMA 20112002).

Etymology. The name henicorhina  is taken from the generic name of the type host and is a noun in apposition.

Differential diagnosis. A. henicorhina  sp. nov. is morphologically similar to A. pirangus Skoracki, Hendricks & Spicer, 2010  described from Piranga ludoviciana (Wilson)  ( Passeriformes  : Cardinalidae  ) from USA ( Skoracki et al. 2010 a). In the females of both species each medial and lateral branch of the peritremes has 2 and 5 chambers respectively; setae c 1 and se are subequal in the length; setae f 2 are about 3 times longer than f 1; setae h 2 are distinctly longer than f 2; setae h 2 are about 11-12 times longer than h 1 and f 1 and the coxal fields of legs I–IV are sparsely punctate. This new species differs from A. pirangus  by the following characters: in females of A. henicorhina  , the lengths of aggenital setae ag 1, ag 2 and ag 3 are 50 –55, 40– 50 and 80–90, respectively; the hysteronotal shield is well sclerotized; fan-like setae of legs III and IV are with 5 tines. In females of A. pirangus  , the lengths of aggenital setae ag 1, ag 2 and ag 3 are 105–120, 115 and 130–145, respectively; the hysteronotal shield is indistinct and weakly sclerotized; fan-like setae of legs III and IV are with 8 tines.
