Bochkovia gen. nov.

Diagnosis. FEMALE. Gnathosoma . Hypostomal apex smooth, without protuberances. Stylophore constricted posteriorly. Peritremes M-shaped with distinct chambers in longitudinal and transverse branches. Stylets of movable digits dentate, with two teeth each. Idiosoma . Propodonotal shield entire. Propodonotal setae arranged 2–2–2. Hysteronotal shield fused to pygidial shield. Setae d1, d2 and e long. Setae d1 situated closer to d2 than to e. Three pairs of aggenital setae present. Genital and pseudanal series with two pairs of setae each. All dorsal setae, except terminal setae (f1, f2, h1 and h2) thick and knobbed. Legs. Apodemes I parallel, not fused to apodemes II, apodemes III and IV absent. Claws subequal in size and shape, strongly curved. Dorsal setae dF, dG and dT of legs I and II knobbed. Setae vs of legs I and II absent.

MALE. Characteristics as in female except: stylets of movable digits edentate; propodonotal setae arranged 2–1–1–2; setae d1, d2 and e short; setae d1 situated closer to d2 than to e; all body setae smooth; dorsal setae of legs smooth.

Host order: Charadriiformes .

Type species: Bochkovia phalaropi sp. nov.

Etymology. This generic name is dedicated to a prominent acarologist and our friend, Dr. Andre V. Bochkov (Zoological Institute of the Russian Academy of Sciences, St. Petersburg, Russia).

Differential diagnosis. Bochkovia gen. nov. is similar to Procellariisyringophilus Schmidt et Skoracki,

2007 (= Syringonomus Kethley, 1970 ). In females of both genera, the hypostomal apex is without the protuberances, the lateral hypostomal teeth are absent, the stylophore is constricted posteriorly, the propodonotal region bears six pairs of setae arranged 2–2–2, two pairs of genital setae and three pairs of aggenital setae are present, apodemes of legs I are slightly divergent, and leg setae vsII are absent. This new genus is distinguished from Procellariisyringophilus by the following characters: in females of Bochkovia gen. nov., movable cheliceral digits are dentate, the hysteronotal shield is fused to the pygidial shield, two pairs of the pseudanal setae are present, the legs are subequally thickened, leg setae vsI are absent, and the claws are strongly curved. In females of Procellariisyringophilus , the cheliceral stylets are edentate, the hysteronotal shield is separated from the pygidial shield, one pair of the pseudanal setae is present, legs I are thicker than legs II, leg setae vsI are present, and the claws are typically opened.
