From the Palaearctic only two species of the genus Krendowskia are known (Smit, 1997): K. latissima and K. levantensis. The latter differs from K. latissima by the hook-like tooth at the ventrodistal edge of P- 4. In addition, it differs from K. latissima by much larger size and striated sclerotized integument. The female specimens collected from Kahramanmaraş Province are in perfect agreement with K. levantensis, which was up to now only known from Israel and Iran. Distribution. Israel (Smit 1997), Iran (Pešiċ & Saboori 2007).

Arrenurus Esen, Erman & Dilkaraoglu, 2013, syn. nov.

Arrenurus (s.str.) vavrai Thon, 1899 Arrenurus (s.str.) kurui Erman, 1993 syn. nov. Material examined. Elazıġ Province, Kovancılar, Yeniköy village 25.viii. 1989, (14 / 5 /0), leg. Erman; Bingöl Province, Karlıova, Toklular village, 16.vii. 2009, (1 / 3 /0), leg. Esen. Remarks. Due to the presence of well developed hyaline extensions on petiole ventrolaterally, the similarity of A. vavrai and A. kurui was stated by Smit et al. (2000) firstly. In the original description Erman (1993) compared A. kurui with A. processiger Viets, 1930 and A. zapus Cook, 1976, but was not aware of the close similarity with A. vavrai Thon, 1899. Examination of the specimens from Eastern Anatolia (Elazıġ and Bingöl Province–Erman & Özkan 2000; Esen 2011) show that, due to the concave anterior margin of idiosoma, blunt humps on dorsal shield, short cauda and pygal lobes, associated setae of petiole extending to posterior margin of petiole, and similar dimensions of idiosoma, petiole and total length of palp (Thon 1899), A. kurui is in perfect agreement with A. vavrai. Thus A. kurui should be considered a junior synonym of A. vavrai. A description of the Turkish specimens are given below. Male: Idiosoma 864–1135 long (including petiole), 684–864 wide. Anterior margin of idiosoma concave, dorsal shield incomplete, dorsal shield W 384–553, dorsal furrow not extending to lateral margin of idiosoma. Dorsal humps blunt (fig. 6 A). Genital plates wide and extending to lateral margin of idiosoma. Medial distance between fourth coxal plates relatively large (fig. 6 B). Cauda distinct, pygal lobes very short. Hyaline membrane short, with a concave posterior margin. Petiole rounded posteriorly. Petiole L/W 88–110 / 69–76. Petiole with hyaline extensions on ventrolaterally (figs. 6 C, D). Ligulate process small, rounded posteriorly and not extending to posterior margin of petiole (fig. 6 E). Associated setae nearly extending to posterior margin of petiole. Palp total L 283–320. dL of palp segments: P- 1 29–33, P- 2 73–81, P- 3 53–64, P- 4 81–89, P- 5 47–53. P- 2 medially with five setae (fig. 6 F). IV-L- 4 with a spur. Female: Idiosoma L/W 1428–1460 / 1190–1200, anterior margin of body straight, posterolateral corners slightly distinct, dorsal shield L/W 1080–1100 / 816–825. Gonopore L/W 126 / 153, genital plates large. Medial distance of fourth coxal plates as wide as two genital valves (fig. 6 G). Genital field W 790–815. Palp total L 334, dL of palp segments: P- 1 39, P- 2 84, P- 3 65, P- 4 95, P- 5 51. P- 2 medially with five setae. Distribution.

Remarks. Due to the well developed pygal lobes, rounded posterior margin of petiole, concave anterior margin of body and incomplete dorsal shield, the new species is very similar A. ayyildizi Erman, 1993 and A. virens Neuman, 1880. It can be distinguished from A. ayyildizi in the well developed dorsal humps, the posterior margin of the hyaline membrane wider, the associated setae of petiole not extending to posterior margin (in A. ayyildizi associated setae extending to posterior margin of petiole-see fig. 1 F) and posterior margin of ligulate process pointed. Furthermore, differences are found in larger idiosoma size (in A. ayyildizi collected from Bingöl Province maximum L/W 1075 / 680) and preference habitat (A. ayyildizi collected from streams). Arrenurus virens differs from the new species in the wider hyaline membrane posteriorly, the shorter petiole, the associated setae of petiole extending to posterior margin and the genital plates not extending to lateral margin of idiosoma. The female of the new species is, due to the distinct posterolateral corners and shape of the genital field, similar to the female of A. ayyildizi. It differs from A. ayyildizi in the larger idiosoma size (in A. ayyildizi maximum L/W 1027 / 866) and genital valves with wider triangular chitinized patches.Published as part of Esen, Yunus, Erman, Orhan & Dilkaraoglu, Sibel, 2013, Contribution to the study of arrenuroid water mites (Acari: Hydrachnidia) from Turkey, pp. 73-83 in Zootaxa 3666 (1) on page 74, DOI: 10.11646/zootaxa.3666.1.7, http://zenodo.org/record/28385

Gonopore L/W 152 / 205, genital plates large and wide, slightly enlarged in the middle, genital field close to posterior margin of Cx- 4. Medial distance of fourth coxal plates as wide as one genital valve. Genital field W 654. Excretory pore very close to genital field, far anteriorly of associated setae. Capitulum ventral L 190, chelicera L 230. Palp (fig. 4 B) total L 362, dL of palp segments: P- 1 40, P- 2 84, P- 3 63, P- 4 110, P- 5 65. P- 2 medially with six setae. Dorsal L of I-L: 95 - 90-142 - 178 - 174-204, IV-L- 4-6: 265 - 231-244. Records from Turkey: Antalya Province (Gülle et al. 2011). Remarks. The illustrations of Gülle et al. (2011) did not describe the most important characteristics of A. antalyensis, and in our opinion there are some mistakes in the measurements of the petiole of this species. Examination of one male specimen from the type locality and specimens of Kahramanmaraş Province show that the dorsal humps are not fused distally, the petiole is wider, and P- 2 has medially 6–7 setae. Some of the measurements of the petiole provided in the original description (in parentheses) differ considerably from our measurements: petiole L/W 140 / 120 (125–129 / 89–92). Other measurements of the holotype and the paratype do not differ remarkably from the values given here. Furthermore, the illustration of the palp was probably drawn laterally, because P- 2 is with one seta, while the sword seta of P- 4 is clearly visible, which must be an error. The male of A. antalyensis is similar to that of A. distans due to the short pygal lobes, the enlarged petiole posteriorly, the trapezoid hyaline membrane and it’s concave posterior margin. However, A. distans differs from A. antalyensis by having a pointed posterior margin to the ligulate process which itself only slightly extends beyond the posterior margin of the petiole (in A. antalyensis the ligulate process extends far beyond the posterior margin of the petiole). In lateral view, the petiole of A. distans is narrowed posteriorly (see Smit et al. 2000, fig. 8) whilst that of A. antalyensis is enlarged posteriorly and the associated setae of the petiole of A. distans do not reach the petiole posterior margin. The female of A. antalyensis is easily distinguished from all other species by the excretory pore lying very close to genital field and far anteriorly of associated setae. This character is unknown in other species of the subgenus Arrenurus. Palp shape and setation are in perfect agreement with the male of this species. Furthermore, due to the distinct posterolateral corners and wide genital plates, A. antalyensis females are similar to those of A. ovatipetiolatus but differ in the genital plates which are wider in the middle; the wider medial distance of the fourth coxal plates and the genital valves with narrow triangular sclerotized patches.

Hyaline membrane trapezoid, widest at base, strongly narrowed posteriorly, posterior margin slightly concave. Petiole L 210–218, posterolaterally with a hyaline extension, tip of hyaline extension narrowed or pointed. Associated setae of petiole extending beyond posterior petiole margin (fig. 5 C–D).

Dorsal L of I-L: 59-72 - 100-132 - 134 - 128, IV-L- 4-6: 158-167 - 190. Remarks. The original description of the male of A. kermanensis was based on a specimen which was not completely sclerotized (Pešiċ et al. 2011). Therefore, some differences are found between the holotype and the well sclerotized specimens from Turkey. Compared with the holotype, the specimens from Turkey are characterized by the straight or slightly concave anterior idiosoma margin, a distinct cauda, pygal lobes well developed, the posterior margin of the hyaline membrane concave and tip of butterfly nut-shaped extention of the petiole narrowed posterolaterally. The females of this study have a complete dorsal shield and gonopore valves with small triangular patches (in the original description a single female specimen has an incomplete dorsal shield, and the gonopore valves have medially fused sclerotized patches). This record shows that A. kermanensis has a wider distribution area. Up to now the species only known from the type locality in southern Iran. Distribution. Iran (Pešiċ et al. 2011). New for Turkey.Published as part of Esen, Yunus, Erman, Orhan & Dilkaraoglu, Sibel, 2013, Contribution to the study of arrenuroid water mites (Acari: Hydrachnidia) from Turkey, pp. 73-83 in Zootaxa 3666 (1) on pages 76-80, DOI: 10.11646/zootaxa.3666.1.7, http://zenodo.org/record/28385

The mite fauna of Eksisu Marshes in Erzincan (Turkey)

Reedbeds can be characterized as forming a transition between the aquatic and terrestrial ecosystems. They have distinctive animals adapted to living in aqueous conditions. Because of the lack of data on the mite fauna in marsh habitats of Turkey, this faunistic study was conducted in the Eksisu Marshes, which resulted in collecting and determining 58 species and 36 genera belonging to 29 families. Of these, Stigmaeus sphagneti (Hull), Neothrombium neglectum (Bruyant), Podothrombium macrocarpum Berlese, Johnstoniana eximia (Berlese), Calyptostomata velutinus (Muller), Heminothrus humicola (Forsslund), Astegistes pilosus (Koch), Achipteria coleoptrata (Linnaeus), and Lauritzenia elegans (Kunst) are new records for the Turkish fauna. The diagnostic features and distributions throughout the world of the species that were determined as newly recorded for Turkey are given. This is also the first report of the families Calyptostomatidae and Neothrombidiidae from Turkey
