Species List of Quadroppiidae(Acari: Oribatida) with Descriptions of a New Genus and two New Species.

Two new species of the genus Quadroppia (Acari: Oribatida: Quadroppiidae) from Turkey

“…The new species is well characterized, the lamellae that are parallel to each other, the bothridia directed towards the front of the prodorsum and interbothridial mound level with anterior border of bothridia. For this reason, the new species is distinguishable from all known species of the subgenus (Gordeeva 1983;Minguez et al 1985;Woas 1986;Ohkubo 1995;Subias & Arillo 2001;Subias 2008). The new species differs also from Quadroppia (Quadroppia) quadricarinata, in the following characters: (1) the lamellae parallel to each other (convergent anteriorly in quadricarinata), (2) interbothridial mound level with anterior border of bothridia (extends to the middle of the lamellae beyond the anterior border of bothridia in quadricarinata), (3) the apex of sensilli level with anterior border of lamellae (reach to the middle of the lamellae in quadricarinata), (4) the bothridia directed towards the front of the prodorsum (directed laterally in quadricarinata).…”

“…This genus is represented by the two subgenera Quadroppia Jacot, 1939and Coronoquadroppia Ohkubo, 1995(Subias 2008. The subgenus Quadroppia (Quadroppia) is distinguished from Quadroppia (Coronoquadroppia) by the absence of the frontal appendage which appears in front of translamella (Ohkubo 1995). There are twenty-two known species of the genus from all zoogeographical regions except the Antarctica (Subias 2008;Baran & Ayyildiz 2007).…”

Quadroppia (Coronoquadroppia) sezeki sp. n. (Acari: Oribatida), a new soil mite from Turkey

“…The terminology used here is that of Minguez et al (1985) and Ohkubo (1995). Measurements and descriptions are based on specimens mounted in temporary cavity slides on permanent slides.…”

“…The subgenus, Q. (Coronoquadroppia) can be easily distinguished by the frontal appendage which appears in front of translamella (Ohkubo 1995). There are fourteen known species of this subgenus in the world (Subías 2004(Subías , 2007Baran & Ayyıldız 2007).…”

A New Species of the Family Quadroppiidae and a New Subspecies of the Family Oppiidae (Acari, Oribatida) from Iran

“…Then, two genera, Hexoppia Balogh, 1958and Borhidia Balogh and Mahunka, 1974 were added. Ohkubo (1995) proposed the genus Coronoquadroppia with Coronoquadroppia parallela Ohkubo, 1995 as the type species [Subías (2004) lowered the genus to the subgeneric rank, and synonymized the type species with Oppia circumita Hammer, 1961], which differs from Quadroppia in having a frontal appendage in front of the transcostula. Most recently, Subías (2009) listed 23 species belonging to three genera of this family in his catalogue.…”
