Bahramian et Hajiqanbar (Dolichocybidae) that is easily discernible by some modified foliate setae on tarsi I–III; and Tarsopolipus massai Husband, 1989 (Podapolipidae) for which Scarabaeus pius is a new host record.Key words: Heterostigmatina, Pavania, Tarsopolipus, new species, host record.INTRODUCTIONBeetles of the superfamily Scarabaeoidea are one of the most typical co-leopterans, and even insects, to carry various kinds of mites. The mites from groups Mesostigmata, Prostigmata and Astigmatina encompass representa-tives associated with these beetles (e.g. Masan & Halliday 2009, Costa 1963, Oconnor 1982, Houck & Oconnor 1991, Bochkov & Klimov 2005, Kaliszews-ki et al. 1995). In Prostigmata, some heterostigmatic families such as Dolicho-cybidae (Hajiqanbar & Khaustov 2010), Scutacaridae (Ebermann et al. 2003), Pygmephoridae (Khaustov & Trach 2012), Microdispidae (Hajiqanbar et al. 2012) and Podapolipidae (Husband 1989) include species that have relation-ships with this group of beetles. Some mentioned families have only pho-retic relationship with scarab beetles (like Dolichocybidae, Pygmephoridae and Scutacaridae) however, some others are parasite of their hosts (like Po-dapolipidae).The purpose of this paper is to describe a new species belonging to the genus Pavania associated with the Scarabaeus pius (Coleoptera: Scarabaeidae), compare the species with closely related congeners and report of the previ-ously described species Tarsopolipus massai on the aforementioned scarab bee-tle, that provide a new host record for this parasitic mite.Acta Zool. Acad. Sci. Hung. 61, 201526 BAHRAMIAN, M., HAJIQANBAR, H. & TALEBI, A. A.MATERIAL AND METHODSMites were removed from a scarabaeid beetle collected directly from their habitat, livestock dung pads. Mite specimens were cleared in lactophenol solution and mounted in Hoyer’s medium. Terminology follows mostly that of Lindquist (1986) and in part (chae-totaxy of tarsus I of the Pavania) Rahiminejad et al. (2011). The morphology of the mites was studied by a light microscope with phase contrast (Olympus BX51). All measurements in the description are given in micrometers for the holotype and four paratypes in paren-theses. In descriptions of the leg setation the number of solenidia is given in parenthesis. Details of geographical coordinates have been recorded using GPS. The scarabaeid host beetle was identified by G. V. Nikolaev (Al-Farabi Kazakh National University, Almaty, Kazakhstan). The holotype is deposited in the Acarological Collection, Department of En-tomology, Faculty of Agriculture, Tarbiat Modares University, Tehran, Iran. One paratype is deposited in the Collection of Department of Animal Taxonomy and Ecology, A. Mick-iewicz University, Poznan, Poland, and an other paratype in U.S. National Museum of Natural History, Washington D.C., U.S.A. Host beetle is retained with the holotype.TAXONOMYFamily Dolichocybidae Mahunka, 1970Pavania lanceolata Bahramian et Hajiqanbar sp. n.(Figs 1–7)Diagnosis.

Unknown.Differential diagnosis. The species Pavania lanceolata Bahramian et Haji-qanbar sp. n. is readily distinguished from all other species of the genus by some modified lanceolate setae on tarsus I (pv’, pv”, u’, u”), tarsus II (u’, tc”, pv’, pv”) and tarsus III (pv”). Based on drawings of Mahunka (1975), at least, tarsus II seta u’ in Pavania endroedyi Mahunka, 1975 is foliate. Regardless of this trait, the new species is similar to its congeners Pavania fusiformis Lombar-dini, 1949; P. endroedyi and P. kamalii Hajiqanbar et Khaustov, 2010 in presence of trichobothridia and setae f longer than e. The new species differs from Pava-nia fusiformis by seta c2 twice as long as c1 (seta c2 less than twice as long as c1 in P. fusiformis), seta d longer than c1 (setae c1 and d subequal in P. fusiformis), seta sc2 about 3.5 times longer than c1 (seta sc2 about 2.5 times longer than c1 in P. fusiformis). The new species differs from Pavania endroedyi by seta c2 two times longer than c1 (setae c1 and c2 subequal in P. endroedyi), seta v1 longer than e (setae e longer than v1 in P. endroedyi), distance d-d longer than e-e (distance e-e longer than d-d in P. endroedyi). The new species also differs from Pavania kamalii by seta c2 twice as long as c1 (seta c1 longer than c2 in P. kamalii), seta f at least three times longer than e, (seta f about two times longer than e in P. kamalii), seta d longer than c1 (seta c1 longer than d in P. kamalii).Acta Zool.

The host beetle was collected from its habitat i.e. live-stock dung pads, located in Iran, Southern Isfahan Province, near Semirom town, 31.26°N, 51.29 °E, 2,460 m, 8 May 2013, leg. M.

Italy, Iran, France, Spain, East Africa.Remarks. This is a new association between this parasitic mite and the scarab beetle Scarabaeus pius. All previous host records of this mite are Scara-baeus semipunctatus reported by Husband (1989) in Italy, France, Spain and East Africa; by Hajiqanbar et al. (2007) in the vicinity of Galugah Forest, Mazandaran Province, northern Iran; and by Mortazavi and Hajiqanbar (2012) in Kerman Province, Iran.DISCUSSIONThe genus Pavania now includes 20 species of which 9 (c. 50%) are pho-retic on 4 genera of Scarabaeidae: Copris, Onthophagus, Gymnopleurous and Scarabaeidae (Cross 1965, Sevastianov 1980, Hajiqanbar & Khaustov 2010, Rahiminejad et al. 2011, Loghmani et al. 2013, present study). Including Scara-baeus pius as a new host record for mites of the genus Pavania, the number of Scarabaeus species carrying mites of this genus is raised to 8 (see Table 1). All mentioned host beetles are dung dwelling as this habitat provides a rich source of fungi for mite nutrition. Although no life history of the species of Pavania has already been reported, they appear to be fungivorous in this sub-strate and, perhaps help in spreading fungi spores.There are five podapolipid genera parasitizing scarab beetles: Dilopoli-pus Husband, Archipolipus Husband, Stenopolipus Husband, Scarabapolipus Husband et Kurosa, and Tarsopolipus Berlese. Nine species of the genus Tar-sopolipus are associated with three scarabaeid genera Drepanopodes, Kheper and Scarabaeus. Including S. pius, six species of Scarabaeus are exploited by mites of the genus Tarsopolipus. Heretofore, Tarsopolipus massai was found only on Acta Zool. Acad. Sci.
