Hypoaspis terrestris ( Leonardi, 1899)

Laelaps terrestris Leonardi, 1899: 508 .

M a t e r i a l. Ukraine, Odesa Region, Odesa, Luzanivka microdistrict (46.55 N, 30.75 E), park, on Pentodon idiota Herbst, 1789 ( Scarabaeidae : Dynastinae), 24.09.2006, 18 ♀ (V. A. Trach); Kodyma District, vicinity of Olexandrivka (48.00 N, 29.23 E), meadow, on P. idiota , 23.05.2009, 3 ♀ (V. A. Trach).

D i s t r i b u t i o n. Armenia ( Ohanjanian, 1978); Italy ( Leonardi, 1899); Iran ( Joharchi, Halliday, 2011); Ukraine ( Bregetova, 1977).

Hosts. Cetoniinae g. sp. ( Leonardi, 1899); Copris hispanus (Linnaeus, 1764) ( Bregetova, 1977) ; Oryctes nasicornis ( Ohanjanian, 1978) ; Pentodon idiota ( Joharchi, Halliday, 2011; this study); Polyphylla olivieri ( Joharchi, Halliday, 2011) .

Remarks. We examined 10 specimens of Copris hispanus from Kherson Region and Crimea, but no mites were found. Hypoaspis terrestris differs from H. krameri by the longer dorsal (j3, z4, Z4) and ventral (st1–st3) setae.

Fourteen species of scarabaeid beetles of the Ukrainian fauna are known to be hosts for mites of the family Laelapidae ( table 2). In our study, mites were found on seven beetle species ( Anoxia orientalis , A. pilosa , Polyphylla alba , P. fullo , Amphimallon solstitiale , Oryctes nasicornis , Pentodon idiota ). On five beetle species ( Anoplotrupes stercorosus , Copris hispanus , Melolontha melolontha , Phyllognathus excavatus , Osmoderma coriarius ), mites were not found; two species of Scarabaeidae ( Anoxia villosa , Rhizotrogus aestivus ) were not studied.
