A new species of water mite Atractides (Atractides) turcicus sp. n. (Acari: Hydrachnidia: Hygrobatidae) from Turkey

Abstract

In this study, the structural characteristics, unique features, various organ measurements of males and females of the water mite Atractides (Atractides) turcicus sp. n. from Turkey are described. In addition, the study compares their characteristics with related species.

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

“…This in turn has increased the eutrophication in the lake a lot. As a result, the amount of oxygen in the lake has decreased quite a lot which in turn has resulted in putting species with low oxygen tolerance under pressure [11]. The fact that the water mite species discovered within the scope of our study and found in Eber Lake are such which are found on the surface areas of pelagic regions proves this point.…”

“…Table 1 indicates that the number of water mite species detected in Karamık Lake are at the expected level while the number for Eber Lake is far below the expected level. In terms of habitats, the species inhabiting Eber Lake were surface species [11]. The fact that the number of species discovered in Karamık Lake indicates that the lake is in a state of ecologic balance and that the species establishing the limnofauna are not about to be seriously threatened in the near future.…”

“…The study regarding the relationship and impact level of water elements on the distribution of water mite species revealed that there is intense eutrophication in Eber Lake due to excessive nitrogen and phosphate domestic waste [11]. In fact as a result of eutrophication putrefaction in the lake has increased and the pollution level has reached an alarming level.…”

“…Both lakes are classified as Class II (100 -20,000 in 100 ml) for fecal coliform content. A census performed with reproduction results achieved with Blood agar and bile-eskulin agar at 37˚C and 45˚C revealed that the ratio of D group fecal streptococci was 72% in Eber Lake and 24% in Karamık Lake [11]. According to these results domestic waste is being discharged intensely into Eber Lake and as a result the eutrophication ratio of the lake continues to increase (Figure 1).…”

Contributions to the knowledge of the water mite fauna (Acariformes, Hydrachnidia) of Türkiye with descriptions of two new species

“…Remarks: Due to the strongly projected ventrodistal protrusion on P-2 and similar morphology of I-L (I-L-5 with short, equally rod-shaped sword setae and the stout, slightly modified I-L-6), the male of new species resembles Atractides dentipalpis (Walter, 1935) and A. turcicus Aşçı, 2009. Atractides dentipalpis was originally described from Algeria on the basis of a female specimen (Walter, 1935). Later, Boyacı (2007) reported A. dentipalpis from Isparta, Türkiye on the basis of both female and male sexes, and presented the first description of the male.…”
