A new species of the genus Rhinoppia (Acari, Oribatida, Oppiidae) from Turkey

A new species of oribatid mite of the family Oppiidae, Rhinoppia (Rhinoppia) alidagiensis n. sp. is described from soil and litter in Kayseri Province, Turkey. The new species differs from the other species of Rhinoppia (Rhinoppia) by the shape of rostrum, sensillus, body dimensions and number of genital setae.


INTRODUCTION
The number of species and subspecies of oribatid mites in the world is 9910 (Subías, 2004(Subías, , updated 2015. In Turkey, however, the number of the identified species of oribatid mites is 143 (Özkan et al., 1994;Erman et al., 2007). The number of these taxa can be at least 4-5 times through further studies to be undertaken in Turkey, due to habitat heterogeneity, based on comparison with the fauna of the other countries in the Palaearctic region.
The genus Rhinoppia can be characterized by the following features: Rostrum smooth or incised; costulae absent or reduced to the bothridial costulae that exist between the bothridia and the interlamellar setae; interbothridial tubercles present; sensilli fusiform or pectinate; notogastral cristae absent; anterior edge of notogaster without humeral process; ten pairs of notogastral setae; setae c2 present; genital plates with six pairs of setae, exceptionally with five pairs; lyrifissures iad paraanal in position

MATERIALS AND METHODS
All specimens were collected from soil and litter using a standard Berlese-Tullgren funnel extractor. For microscopic study, mite specimens were cleared in 80 % lactic acid and mounted on microscopic slides in modified Hoyer's medium. Drawings were made with the aid of a camera lucida attached to the compound microscope. Examined materials were transferred into 70 % ethanol with glycerol (up to 5 %) for the preservation.
The specimens to be studied using the SEM were cleaned by soaking in Terg-a-zyme solution for 6-12 h, followed by brief (1-2 s) submersion in an ultrasonic bath. They were dried using critical point method, mounted on Al-stubs, and gold-coated in a Polaron sputter coater apparatus.
Measurements and description are based on specimens mounted in temporary cavity slides and on permanent slides. The terminology used in this paper follows Grandjean (see Travé and Vachon, 1975), Balogh (1983), and Subías and Balogh (1989) as well as those by Norton and Behan-Pelletier (2009).
