| Abstract | * Correspondence: f_durucan@hotmail.com Halacaridae is a family of meiobenthic mites found in marine, brackish, and freshwater habitats around the world. It includes more than 1100 described species belonging to 64 genera (Bartsch, 2006, 2009). In Turkey, the first taxonomic study on marine halacarids was done by Bartsch (2000), who reported Isobactrus ponticus Bartsch, 2000 from the Black Sea coast of the province of Sinop. Subsequently, Bartsch (2001, 2004, 2013, 2015) described three new species and reported 18 new records from the same province. Subsequently, Agaue chevreuxi (Trouessart, 1889) and Thalassarachna affinis (Trouessart, 1896) were recorded from the Bostancı Coast of İstanbul (Sea of Marmara) by Bilecenoglu et al. (2013) and Kapiris et al. (2014). In addition to these studies in Sinop and İstanbul, Mytilineou et al. (2016), Stamouli et al. (2017), Durucan and Boyaci (2016, 2017, 2018a, 2018b), and Durucan (2018) carried out taxonomic studies on marine halacarids from the Mediterranean Sea coast of Turkey. Despite all of these investigations, the genus Scaptognathus has not been recorded so far in Turkey. Scaptognathus Trouessart, 1889 is one of the most species-rich genera of Halacaridae with 31 named species in the world (Bartsch, 2009), of which four (S. hallezi, S. sabularius, S. tridens, and S. tereninus) are known from the Mediterranean Sea. Recently, the author had a chance to examine some halacarid specimens collected in Antalya Province, Turkey, and found some Scaptognathus specimens among them. The present paper aims to report the results of taxonomic examination of these Scaptognathus specimens. The species obtained in the present study and so far recorded in past publications are summarized in an updated checklist for marine Halacaridae known from Turkey. In the present study, samples of substrate were collected by scuba-diving and snorkeling from Hamit Bey Plajı (Antalya) (36.87555556°N, 30.70722222°E) on 29.VI.2017 from medium-coarse sand habitats (7 m depth) and Kaş (Antalya) (36.15694444°N, 29.62833333°E) on 10.IX.2016 from fine to coarse sand habitats (25 m depth) (Figure 1). Immediately after collection, mites were extracted by washing the substrates. The meiofauna retained in the set of sieves (63 μm, 500 μm, 1 mm) was sorted under a binocular microscope (Nikon SMZ 10). In the laboratory, mite specimens were cleared in lactic acid and mounted in glycerin jelly. Drawings were prepared with a camera lucida (Nikon Eclipse E400). The specimens were kept in the first author’s personal collection in Antalya. All material was collected by the author. As a result, a total of 56 Scaptognathus specimens were identified to species level as either S. hallezi or S. sabularius. The following abbreviations are used in the description and illustrations: AD, anterior dorsal plate; AE, anterior epimeral plate; ds, dorsal setae, from anterior to posterior: ds-1 to ds-7; GA, genitoanal plate; GO, genital opening; gn, gnathosoma; OC, ocular plate (s); PD, posterior dorsal plate; PE, posterior epimeral plate (s); P-1 to P-2, first to second segments of palp; pgs, perigenital seta(e); sgs, subgenital seta(e). Abstract: This paper presents the first results of a study on the Scaptognathus (Acari: Halacaridae) mites from the Mediterranean Sea coast of Turkey. Two species, S. hallezi Trouessart, 1894 and S. sabularius André, 1961, are newly recorded from Turkey. They are briefly described with drawings, habitats, and worldwide distributions. Additionally, a checklist is provided for the marine halacarid species of Turkey. |
