Study on the Impact of Elements in Water on the Diversity of Water Mites(Acari,Hydrachnidia)Species

In this study the distribution and relationships of element levels in water and water mite species (Acari, Hydrachnidia) selected as model organisms have been examined in two different lakes. Water samples from Eber and Karamik Lakes were analyzed with ICP (ICP-OES Instrument Spectro Genesis Fee, Germany) equipment to determine the element levels in the water. That impact level of these elements on the distribution of species was discussed. Change in the lake water composition was not a significantly determining factor in the number of species and diversities of water mites. However, eutrophication was observed to be a determining factor on the distribution of species.

The Application of Ultraviolet Spectrophotometry(UV)on Some Water Mite Species(Acari,Hydrachnidia)

In this study an ultra violet analysis, which is a spectrophotometric method, was applied for the first time as a structural analysis of the group. The following species were collected from Karamik Lake in Afyon Province, Turkey between April and August, 2015, Hydryphantes flexiosus, Hydrodroma despiciens, Georgella helvatica, Eylais infundibulifera, Hygrobates nigromacutlatus and Torrenticola brevirostris. These species were separately analyzed by Ultraviolet Spectrophotometer (US) and the results assessed using graphical readings. The affiliations between the species were read from the graphical curves of each species and then compared in terms of the curves.

Assessment of the Phylogenetic Affiliation Levels of Water Mite(Acari,Hydrachnidia)Species with the Elemental Analysis Method

10 different species of water mites which are Georgella helvetica, Eylais extendens, Hydrachna globose, Hydrachna prosifera, Hydrachna skorikowi, Hydrodroma despiciens, Hydryphantes dispar, Limnesia fulgida, Eylais setosa, Hydryphantes flexuosus were used in this study. The total masses of these species were measured as mg with the use of an elemental analyzer to calculate the percentage of the organic components of their structures. The achieved values were assessed separately for each species and element with the interpolation method. Out of these organic elements, the amount of C with an approximately value of 50% was the highest for all species while the amounts of S which was approximately 1% was determined as the lowest for almost all species. The observed values were discussed in terms of the systematic of water mites.

A newly recorded and a new species of torrenticolid mites (Acari:Hydrachnidiae) from China

A new species of Torrenticola(Acari:Hydrachnidia)is reported from China,namely T.(T.)gladiusirostrum Jia,Gu&Guo,sp.nov.And T.(Megapalpis)distans K.O.Viets,1981 is recorded in China for the first time.Both descriptions and illustrations of these species are provided.The new species is characteristic by:dorsal plate arrangement 2+1;infracapitular bay U-shaped,deep and wide,V2 almost at same level of Ap;gnathosoma ventral apodeme short and blunt,rostrum flat and sword-shaped;P-2 and P-3 ventral processes smooth and pointed,and P-2 ventral process curved upwards,P-4 with two ventral extensions.

First record of Pionacercus Piersig(Acari:Hydrachnidia:Pionidae)from China with redescriptions of two species

The water mite genus Pionacercus Piersig,1894 with two species,Pionacercus anadyrensis Tuzovskij,1990 and Pionacercus leuckartii Piersig,1894,is reported for the first time from China.P.anadyrensis Tuzovskij,1990 and P.leuckartii Piersig,1894 are redescribed and illustrated.

Wandesia(s.str.)boyani Li&Guo,sp.nov.,a new species representing a newly recorded subfamily Wandesiinae Schwoerbel,1961 from China

A new species,Wandesia(s.str.)boyani Li&Guo,sp.nov.,is described and illustrated in detail,which is collected from Qinghai-Tibet plateau,P.R.China,and represents a newly recorded subfamily Wandesiinae(Acari:Hydrachnidiae:Hydryphantidae)to Chinese fauna.The new species is distinguished from its congeners by having stalked acetabula ranged triangularly,developed pregenital sclerite lily-like,E4 at the middle of Ac-1 and Ac-2.
