Water mites of the genusSperchonKramer, 1877 of Kyrgyzstan (Acari: Hydrachnidia: Sperchontidae) with the description of seven new species

Two new water mite species from Kyrgyzstan (Acari, Acariformes, Hydrachnidia)

“…sp. nov. is most similar to S. grigorievka Pešić & Smit, 2020, known from Kyrgyzstan (Pešić & Smit 2020). Both species have a rugose integument, without sclerotized muscle attachment plates, Cx-III with a glandularium, a rostrum shorter than the gnathosomal base, P-2 with a long ventrodistal projection, excretory pore surrounded by a sclerotized ring similar in size to neighbouring glandularia and IV-L-3-5 with a row of scattered plumose dorsal setae.…”

“…With 41 species so far reported, the water mite fauna of Kyrgyzstan is still poorly studied. Water mites of Kyrgyzstan were treated by Daday (1903), Thor (1909), Sokolow (1940), Tuzovsky (2003), and Pešić & Smit (2017, 2018, 2020, 2021a. The genus Sperchon Kramer, 1877 with 11 species is the most diverse, followed by Atractides Koch, 1837 with ten known species from Kyrgyzstan.…”

Sperchon milisai nov. sp., an overlooked new species of water mites (Acari, Hydrachnidia, Sperchontidae) from Montenegro and Croatia, based on morphological and DNA barcode evidence

“…nov. by having a sclerotized excretory pore. The presence of a smooth excretory pore makes the new species similar to S. ampliscutatus Pešić & Smit 2020, a species only known from a stream in the Tian Shan mountains in Kyrgyzstan (Pešić and Smit 2020). The latter species can be separated from the new species by more densely arranged plumose dorsal setae on IV-L-3-5 (in female IV-L-4 of S. ampliscutatus ˃ 12, in S. milisai sp.…”

“…For DNA-barcoding and phylogenetic analysis we used COI sequences obtained from specimens collected in this study as well as published sequence data from BOLD and GenBank. The final dataset for the phylogenetic analysis includes 51 sequences representing Sperchon algeriensis Lundblad, 1942 (n=1), S. ampliscutatus Pešić & Smit, 2020(n=3), S. amuzgari Bader & Sepasgozarian, 1979(n=3), S. clupeifer Piersig, 1896(n=5), S. compactilis Koenike, 1911, S. denticulatus Koenike, 1895 (n=1), S. hispidus Koenike, 1895(n=2), S. hibernicus Halbert, 1944(n=2), S. insignis Walter, 1906, S. milisai sp. nov. (n=3), S. papillosus Thor, 1901 (n=2), S. setiger Thor, 1898 (n=4), S. vaginosus Thor, 1902 (n=4) andS.…”

Water mites of the genus Atractides Koch, 1837 from Kyrgyzstan (Acari: Hydrachnidia: Hygrobatidae) with the description of six new species

“…Distribution -Kyrgyzstan; so far only known from one spring (see Fig 18B in Pešić and Smit 2020) in Tien Shan mountains at an elevation of about 3,300 meters.…”
