Skoracki, M., Zmudzinski, M. & Solarczyk, P., 2017, Ixobrychiphilus, a new genus of the family Syringophilidae (Acariformes: Prostigmata), Acarologia 57 (2), pp. 269-273 : 270

Ixobrychiphilus n. gen.

Zoobank: BEEDD67E-9954-4954-B469-32B6FE2B4ADE

Diagnosis — Female: Small sized syringophilids (total body length 490 – 540). Gnathosoma. Hypostomal apex rounded, without protuberances. Lateral hypostomal teeth absent. Peritremes M-shaped with clearly visible chambers in each branch. Anterior tip of each movable cheliceral digit with 2 teeth. Stylophore rounded posteriorly. Idiosoma. Six pairs of propodonotal setae arranged 2-1-1-1-1. Setae d1 situated closer to d2 than to e2. Agenital series with 3 pairs of setae. Each pseudanal and genital series with 2 pairs of setae. All idiosomal setae smooth and whip-like. Legs. Legs I thicker than II. Antaxial and paraxial members claw pair subequal in size and shape, without basal angle. Apodemes I parallel, not fused to apodemes II. Legs with full complement of setae.

Male: Unknown.

Type species — Ixobrychiphilus wallacei n. sp.

Etymology — The name " Ixobrychiphilus " is taken from the generic name of the host – Ixobrychus , and philus (Gr. phileo – lover of).

Differential diagnosis — This new genus is morphologically similar to Niglarobia Kethley, 1970 associated with charadriiform birds. In females of both species, the lateral hypostomal teeth are absent; the apodemes I are parallel and not fused to the apodemes II; the stylophore is without large tip on the posterior margin. This new genus is distinguished by the following features: in females of Ixobrychiphilus , propodonotal setae are arranged 2-1-1- 1-1; legs I are thicker in comparison to legs II; legs I-IV are with full complement of setae, and claws of legs I-IV are without the basal angles. In females of Niglarobia , propodonotal setae are arranged 2-1- 1-2; legs I and II are equal in thickness; leg setae vsII are absent, and claws of legs I-IV are with the basal angles.
