Abstract
This work deals with taxonomy, geographical distribution as well as known ecology of oribatid mites of the genus Conchogneta Grandjean, 1963 in the world. The majority of species belonging to this genus is known to be widely distributed in Europe, but only three of them are found in other areas of the northern hemisphere. Most species of Conchogneta are inhabitants of litter of various types of forestas, terricolous and epiphytic bryophytes, epiphytic lichens, and soil of steppe, river valleys, moor, oligotrophic bogs, floodland assemblages etc. A new species, Conchogneta glabrisensillata sp. n. is described, and another species, Conchogneta traegardhi (Forsslund, 1947) is redescribed from the northern and western parts of Mongolia, respectively. Conchogneta is recorded for the first time for the fauna of Mongolia. The species status of Conchogneta dalecarlica (Forsslund, 1947) is discussed. Species descriptions are accompanied with detailed illustrations. Furthermore, a key is provided for the identification of adults of the known species of Conchogneta in the world.
Highlights
The oribatid mite genus Conchogneta is one of seven genera in the family Autognetidae, which was erected by Grandjean (1963) with the type species, Autogneta dalecarlica Forsslund, 1947
The members of the oribatid mite genus Conchogneta are limited to the Northern Hemisphere and are mainly known from moist, warm soils and litter habitats in temperate regions
The diversity of this genus is not high, as most of the species were recorded in Europe, except three species, which have expanded distributions in Asia and North America
Summary
The oribatid mite genus Conchogneta is one of seven genera in the family Autognetidae, which was erected by Grandjean (1963) with the type species, Autogneta dalecarlica Forsslund, 1947. The genus comprises seven nominal species and Copyright Badamdorj Bayartogtokh. C. traegardhi (Forsslund, 1947), C. willmanni (Dyrdowska, 1929) and C. dalecarlica (Forsslund, 1947) have rather wide distributions in the Palaearctic or even Holarctic region, and all these three species were recorded in Europe and Asia; C. traegardhi (Forsslund, 1947) was found in North America. Conchogneta iranica Akrami, 2008 is the single species which is only known from Asia (Dyrdowska 1929, Willmann 1941, Forsslund 1947, Winkler 1957, Grandjean 1963, Woas 1986; Marshall et al 1987, Mahunka 2006, 2007, Akrami 2008, Toluk and Ayyildiz 2009)
