Eutogenes frater Volgin (Acari, Cheyletidae): Türkiye Akar Faunasının Yeni Bir Üyesi

Elazığ ilinde (Türkiye) iğde (Elaeagnus angustifolia) altından alınan toprak ve döküntüden üç dişi akar (Acari) örneği, Eutogenes frater Volgin (Cheyletidae) olarak teşhis edildi. Bu tür; dorsal idiosomanın iki plak ile örtülü olması, plak yüzeylerinin papil şeklinde granüllü olması, propodosomal plağın 10 çift, histerozomal plağın 12 çift kıl taşıması ve tüm dorsal kılların yelpaze şeklinde olması gibi özellikleriyle Eutogenes cinsine dâhil olan diğer türlerden belirgin şekilde farklılıklar gösterir. Eutogenes frater, ilk olarak tip yeri olan Bulgaristan’dan tanımlanmış, daha sonra Cezayir, İran ve Macaristan’dan verilmiştir. Bu tür aynı zamanda Giza, Nil Deltası’nın kuzeyi (Mısır) ve Burc el Arab’dan (Birleşik Arap Emirlikleri) da bilinmektedir. Çalışmada, türün tanımı ile birlikte faz kontrast ve diferansiyel interferans kontrast (DIC) donanımlı mikroskopta çekilmiş fotoğrafları verilmiştir. Bu eser, Türkiye’den Eutogenes cinsinin bulunduğuna dair ilk bildirimdir.

Eutogenes frater Volgin (Acari, Cheyletidae): A New Member of the Acarofauna in Turkey

Three female mite (Acari) specimens collected from litter and soil under silverberry (Elaeagnus angustifolia) in Elazığ province, Turkey were identified as Eutogenes frater Volgin (Cheyletidae). This species shows distinct differences from other species in the genus, namely dorsal idiosoma covered by two shields, surface of the shields with papilliform granules, all dorsal setae fan-like, propodosomal shield bearing 10 pairs of setae, hysterosoma with 12 pairs of dorsal body setae. Eutogenes frater has been given before from the type locality, Bulgaria, and was later recorded from Algeria, Hungary and Iran. This species has also been known from Giza, the north of the Nile Delta (Egypt) and Burg Al Arab (United Arab Republic). Description of this species with its phase contrast and differential interference contrast (DIC) micrographs are provided here. This is the first reported occurrence of the genus Eutogenes Baker from Turkey.
