Pseudopygmephorellus szekessyi ( Mahunka, 1970 )


Pseudopygmephorellus szekessyi ( Mahunka, 1970)  

This species was described from Hungary from litter in the nest of Microtus Schrank   ( Rodentia   : Cricetidae   ) ( Mahunka 1970). Kaluz (1992) reported it from Norway as phoretic on Geotrupes vernalis (Linnaeus)   ( Coleoptera   : Geotrupidae   ). This species has a wider distribution and until now, it has been found several times from the Palaearctic (including Iran) and Nearctic regions in association with geotrupid and trogid beetles ( Mahunka 1970; Kaluz 1992; Mašan 1993; Khaustov 2008; Philips 2009; Katlav et al. 2015b).

Material examined. One female, Iran, Northwestern Iran , Ardabil province, forest park, vicinity of Meshginshahr , 38.23°N, 47.41°E, phoretic on Aphodius vittatus Say   ( Coleoptera   : Scarabaeidae   ) collected in dung pads of cow, 14 May 2016, coll. M. Sobhi. GoogleMaps  

Remarks. This species was transferred by Khaustov (2008b) from the genus Pygmephorellus   to the genus Pseudopygmephorellus   . The genus Pseudopygmephorellus   includes six species among which only two species are associated with scarabaeid beetles as follows: P. mazandaranicus Katlav & Hajiqanbar, 2015   phoretic on three different scarabaeid dung beetles, Onthophagus   sp., Aphodius depressus (Kugelann)   and A. varians Duftschmid ( Katlav et al. 2015b)   ; and P. szekessyi   phoretic on Aphodius vittatus   (current study). The association between the mite P. szekessyi   and beetles A. vittatus   is new.
