Aulobia sittellae, K & Unsöld & K, 2022

K, Maciej Skoracki, Unsöld, Markus & K, Bozena Sikora, 2022, A new species of the genus Aulobia Kethley (Acariformes: Syringophilidae) parasitizing Daphoenositta chrysoptera (Passeriformes: Neosittidae) in Australia, Acarologia 62 (4), pp. 908-915 : 912

Aulobia sittellae n. sp. is morphologically similar to Aulobia dendroicae Kethley, 1970

recorded from two species of the New World Warblers ( Parulidae ) of the genus Dendroica - D. coronata (Linnaeus) and D. nigrescens (Townsend) , both from United States ( Kethley 1970 ; Skoracki et al. 2010). Among all species of the genus, only A. dendroicae and A. sittellae have short and subequal in length propodonotal setae vi, ve, and si.

This new species differs from A. dendroicae by the following features: in females of A. sittellae , each lateral branch of the peritremes has seven or eight chambers; the stylophore is 210–230 long; the hysteronotal shield is not fused to the pygidial shield; hysteronotal setae f2

are 250–295 long; and the lengths of agenital setae ag1, ag2, and ag3 are 170–210, 130–155,

and 200–240 respectively. In females of A. dendroicae , each lateral branch of the peritremes has 12–13 chambers; the stylophore is 170–180 long; the hysteronotal shield is fused to the pygidial shield; hysteronotal setae f2 are 195–215 long; and the lengths of agenital setae ag1,

ag2, and ag3 are 75–80, 60–70, and 90–105 respectively.
