Family Syringophilidae Lavoipierre, 1953 View in CoL Subfamily Syringophilinae Lavoipierre, 1953 Genus Chenophila Kethley, 1970
Type species: Chenophila branta Kethley, 1970 by original designation.
3.1. Chenophila platyrhynchos sp. nov. ( Figures 1–5 View Figure 1 View Figure 2 View Figure 3 View Figure 4 View Figure 5 ) Type material: Female holotype and paratypes: 58 females, 10 males, 10 tritonymphs, 7 protonymphs, and 7 larvae from quills of secondaries of Anas platyrhynchos Linnaeus ( Anseriformes : Anatidae ); collected throughout hunting season (autumn) of 2008 from a midfield pond near the city of Szczecin , Poland (53°27′23″N, 14°26′37″E).
Type material deposition: All type material is deposited at AMU, except 2 female and 1 male paratypes at ZISP and 2 female and 1 male paratypes at ZSM .
Comparative material: 13 female paratypes and 1 male paratype from Anas querquedula Linnaeus ( Anseriformes : Anatidae ); Russia, Kaliningrad Prov., Kurish spit, Rybachi village, 9 June 1957, coll. V. Jygis.
Differential diagnosis: Ch. platyrhynchos sp. nov. is morphologically similar to Ch. kanduli Bochkov & Mironov, 1998 . In females of both species, the hysteronotal shield is present and aggenital setae ag1 and ag3 are unequal in length. The new species differs from Ch. kanduli by the following characters: in females of Ch. platyrhynchos sp. nov., the propodonotal shield is distinctly punctate on the whole surface; each lateral branch of the peritremes has 13–16 chambers; the lengths of idiosomal setae ve, se, and c2 are 80–100, 180–230, and 160–215, respectively; setae si 110–140, always longer than the distance between setal bases si–se. In females of Ch. kanduli , the propodonotal shield is sparsely punctate near bases of setae vi, ve, and si; each lateral branch of the peritremes has 10–13 chambers; the lengths of idiosomal setae ve, se, and c2 are 45–65, 135– 165, and 115–145, respectively; setae si 55–100, subequal or shorter than distance between setal bases si–se (based on comparative material).
Etymology: The epithet “ platyrhynchos ” is directly adopted from the specific name of the host.
