Skoracki, Miej & Sikora, Bozena, 2002, New ectoparasitic mites of the family Syringophilidae (Acari: Prostigmata: Cheyletoidea) associated with birds from Argentina, Zootaxa 27, pp. 1-8 : 5-7

2. Aulobia paraguaiae sp. n. ( Figs 10­13 )

Female ( Figs 10­13 ): Total body length 570 in holotype (570 in one paratype).

Gnathosoma: Gnathosoma punctate ventrally. Hypostomal apex with a pair of median protuberances ( Fig 12 ). Peritremes M­ shaped; each lateral branch with 3 chambers, each transverse branch with 7 chambers ( Fig. 13 ). Stylophore 135 long, slightly constricted posteriorly and not reaching the anterior margin of propodosomal plate.

Idiosoma and legs: Cuticular striations as in figs 10, 11. Propodosomal plate with deeply concave anterior margin. Setae vi, ve, sci, sce and d1 on the plate. The length ratio of setae vi: ve: sci 1:1:1. Hysterosomal plate present, only setae d2 on this plate. Setae d2 equidistant to l1 and l2 or closer to l1 than to l2. Pygidial plate present and punctated, anterior margin indistinct. Setae l4, l5, d4 and d5 on this plate. Epimeres of legs I weakly divergent not adjoining the epimeres II. All coxae punctated. Coxae III and IV weakly sclerotized. Setae p’ and p’’ of legs III and IV with 7 tines.

Lengths of setae: vi (30); ve (30); sci 40 (35); h 165; sce (140); d2 (120); l2 125; l4 195 (205); l5 380; d4 30 (30); d5 35 (30); g1 25; g2 (25); pg1 95; pg2 65 (60); pg3 115 (130).

Male: unknown.

Etymology. The name paraguaiae refers to the generic name of host.

Differential diagnosis. A. paraguaiae sp. n. is closely related to A. dendroicae ( Clark, 1964) from Dendroica coronata ( Passeriformes : Parulidae ) from USA ( Clark 1964). In both species setae vi, ve and sci are subequall; epimeres of legs I not adjoining the epimeres II. This new species is distinguishable from above metioned species by the presence of the following features: (1) total body length 570 (cf 720­810); (2) peritremes with 10 chambers (cf 13­14 chambers); (3) paragenital setae pg2 2 times shorter than (cf subequal to) pg3; (4) pygidial setae l 4 set anteriorly to d4 similar to A. gallinago Bochkov et Mironov, 1998 (cf pygidial setae l 4 set near setae d4 similar to A. virens Skoracki et Dabert, 2001 ).

Type material. Female holotype and female paratype from the Magellan Snipe Gallinago paraguaiae ( Charadriiformes : Scolopacidae ); 1977; Argentina­El Bolson, Rio Negro; leg. Kovacs. All material is deposited at UAM.
