Abalakeus Southcott, 1994 is a junior synonym of "plume-footed" Eatoniana Cambridge, 1898 (Trombidiformes, Erythraeidae)—evidence from experimental rearing

Eatoniana Cambridge, 1898 was previously known exclusively from active postlarval forms. In the course of experimental rearing, larvae showing a strong affinity to members of Abalakeus jahromiensis Sedghi, Saboori et Hakimitabar, 2010, were obtained from a field-collected female of Eatoniana plumipes (L. Koch, 1856). Studies of all members of Abalakeus compared with newly obtained larvae of Eatoniana, resulted in synonymisation of Abalakeus Southcott, 1994 with Eatoniana and of A. jahromiensis with E. plumipes. Complementary data to the previous diagnosis of Eatoniana and information on the biology of E. plumipes are provided. A female of E. plumipes was selected as the neotype. A key to Eatoniana spp. known from larvae is provided.

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.

A review of Gonothrombium Feider, 1950 (Actinotrichida: Microtrombidiidae) with description of a new species from Turkey.

The genus Gonothrombium is reassessed, Gonothrombium oudemansianum (Feider, 1948) redescribed and Gonothrombium ozkani sp. nov. described. All larvae were obtained by experimental rearing from field-collected females. A key to species, for adults and larvae, is provided. The distribution of the genus, hitherto known from Africa and Romania, is extended to the territory of Turkey.

Türkiye Faunası İçin Yeni Bir Cins Kaydı: Sucidothrombium Feider, 1973 (Actinotrichida: Microtrombidııdae)

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.

A new species of the genus Atractothrombium Feider (Acari: Microtrombidiidae) from Turkey

TÜRKİYE FAUNASI İÇİN YENİ BİR TROMBİDİİD (ACARI, TROMBIDIIDAE) TÜRÜ: DOLICHOTHROMBIUM INSIDIOSUM (ANDRÉ, 1926)

Bu calismada, Turkiye akar faunasi icin yeni kayit olan, Dolichothrombium insidiosum (Andre, 1926)’un yapisal ozellikleri, yasama ortamlari ile cinsin zoocografik dagilimlari verilmistir.

The genus Emitrombidium Lombardini, 1949 (Actinotrichida: Trombidiidae) resurrected.

Emitrombidium giocondi sp. nov., a second species of Emitrombidium is described based on postlarval forms originating from Turkey. The history of the genus is retraced. The previous conjectures about the uncertain family affiliation of Emitrombidium are clarified and the genus is reinstated as a member of Trombidiidae. Hitherto records suggest the Mediterranean and Pontic distribution of the genus.
