First records of the genus Paratrombium Bruyant, 1910(Acari: Trombidiidae) from Turkey

* Correspondence: ssevsay@erzincan.edu.tr Trombidiidae Leach, 1815 constitutes a taxon of worldwide distribution. This family includes 23 genera and 206 species in the world (Mąkol and Wohltmann, 2012, 2013). The genus Paratrombium comprises at present 38 nominal species (Mąkol and Wohltmann, 2012; Konikiewicz and Mąkol, 2014; Noei et al., 2015). Of these, 8 species are known exclusively from larvae, 23 from postlarval stages, and only 7 from both larval and postlarval stages. Larvae of Paratrombium are known as parasites of Hymenoptera, Hemiptera, Coleoptera, and Diptera (Noei et al., 2015). Only 4 genera (Trombidium, Allothrombium, Dolichothrombium, and Emitrombidium) have been hitherto known from Turkey (Erman et al., 2007; Mąkol and Sevsay, 2011; Mąkol and Sevsay, 2014; Sevsay et al., 2016). In this paper, we report 2 species of Paratrombium from Turkey for the first time. Mite specimens were taken from northeastern Turkey (Bayburt, Erzincan, Giresun, and Gümüşhane provinces) between 2013 and 2015. Adults were collected with an aspirator directly from soil, or by extraction in Berlese funnels. Larvae were reared from eggs deposited by adults collected in the field. All specimens are deposited in the Biology Department of Erzincan University, Erzincan, Turkey. The morphological terminology follows Mąkol and Wohltmann (2000). All measurements are given in micrometers. Family Trombidiidae Leach, 1885 Genus Paratrombium Bruyant, 1910 Type species Paratrombium egregium Bruyant, 1910 Paratrombium insulare (Berlese, 1910) Adults. Standard measurements in Table 1. Body length 1295–1710; width, 1014–1355. Crista metopica slightly widened, not clearly terminated in its anterior part, does not reach anterior margin of aspidosoma (Figure 1). Opisthosomal setae; uniform, slightly thickened stem, narrowing towards tip, stem densely covered with long and short setulae (Figure 2). Deutonymphs. Standard measurements in Table 1. Setation sparser than in adults. Palptibia with at least 1 long eupathidium placed close to palptibial claw. Opisthosomal setae covered with relatively long and curved setulae. Two pairs of genital acetabula. Larvae. Standard measurements in Table 2. Pedipalp formula 0–N–0–NNN–NNNωωζζζ (Figure 3). Scutum widened anteriorly and great part of surface porous. Scutum covers more than half of dorsal side of body (in unengorged larvae); no distinct fold on both sides of symmetry axis. Anterior part of sclerite widened and longitudinally striated, covering almost half of scutum. Scutellum porous, with 1 pair of barbed setae (Figures 4 and 5). f D formula: 2-2-6-4-4-2-2. Abstract: The genus Paratrombium Bruyant (Acari: Trombidiidae) is recorded from Turkey for the first time based on collections of P. insulare (Berlese, 1910) and P. megalochirum (Berlese, 1910). Each species is illustrated, and briefly redescribed with accompanying drawings. Larvae of both species were obtained by experimental rearing. The updated distribution of species is provided.

Description of a species of the genus Cheylostigmaeus Willmann (Acari: Stigmaeidae) from Ekşisu Marsh, Turkey

Abstract The discovery of both sexes of Cheylostigmaeus variatus sp. nov. from grassy soil at Ekşisu marsh in Turkey adds more data to our knowledge of this genus. We herein describe and illustrate it and also provide a key to the known species in Turkey.
