A new species within the genus Marionina (Enchytraeidae: Annelida: Clitellata) from the southern Black Sea

Abstract A new species of Enchytraeidae, Marionina triplex sp. n. is described from an intertidal mussel bank in Sinop, southern Black Sea coast of Turkey. Marionina Michaelsen, 1889 is a widely distributed and heterogeneous assemblage of species, but while awaiting a revision the new species is placed here, as it appears to belong to a group of small enchytraeids currently associated with this genus. The new species in some aspects resembles other species reported from the Mediterranean–Black Sea area [M. adriaticus Vejdovský, 1877; M. argentea (Michaelsen, 1889); M. brevis Finogenova, 1972; M. spicula (Frey & Leuckhart, 1847)] and some species described from elsewhere (M. cana Marcus, 1965; M. singula Ude, 1896; M. sublitoralis Erséus, 1976; M. ulstrupae Healy, 1996), but it can be distinguished by its body length, number of segments, number and form of chaetae, shape and size of pharyngeal glands and spermathecae, etc. The new species is only 1.4–1.8 mm long, with 20–25 segments, and is thus one of the smallest marine enchytraeids known. It has mostly three chaetae per bundle, and spermathecae with the ampulla of about the same size as the ectal duct, and with a few gland cells attached to the base of the ectal duct.

Littoral Oligochaeta (Lumbriculidae and Enchytraeidae) communities of some mountain lakes in the Eastern Black Sea Range (Turkey)

Abstract Six surveys were carried out during July and August 2005–2007 in order to determine the Oligochaeta fauna of high-altitude lakes located in the Eastern Black Sea Range. With the highest peak, Kaçkar Dagi (elevation 3937 metres), and mountain plateaus at about 3000 metres in elevation, are the highest part of the Eastern Black Sea Range. This range is one of the most important glacial region in Turkey. Some physico-chemical features and Oligochaeta fauna of 39 lakes were determined for the first time, where no previous faunistic studies took place. As a result of the study, a total of 10 taxa was identified, comprising 3 species from Lumbriculidae [(Stylodrilus parvus (Hrabë & Černosvitov, 1927), Stylodrilus heringianus Claparede, 1862, and Lumbriculus variegatus (Müller, 1774)], 7 taxa from Enchytraeidae [(Cognettia sphagnetorum (Vejdovsky, 1878), Cognettia glandulosa (Michaelsen, 1889), Mesenchytraeus armatus (Levinsen, 1884), Mesenchytraeus sp., Henlea ventriculosa (d’Udekem, 1854), Henlea perpusilla Friend, 1911, and Henlea sp.)]. All the taxa represent new records for the region. Stylodrilus heringianus is recorded for the first time in Turkey.

Dicle Nehri (Türkiye) Oligochaeta (Annelida) faunasının taksonomik açıdan belirlenmesine yönelik bir ön araştırma

Turkiye’nin ozellikle dogu bolgelerinin Oligochaeta faunasi hakkinda bilgiler oldukca sinirlidir. Bu bolgede yer alan Dicle Nehri, tarih boyunca onemli bir akarsudur ve antik Mezopotomya uygarliklarinin temel kaynaklarindan biri olmustur. Turkiye’nin dogusunda ve Elazig sehrinin yaklasik 25 km guneydogusunda yer alan Toros Daglari’ndan dogan nehrin yaklasik uzunlugu 1900 km’dir. Ancak bu nehrin sucul makrozoobentik faunasi, sahip oldugu zorlu cografik ve morfolojik sartlar nedeniyle yeterince arastirilamamistir. Yapilan bu calismada, Dicle Nehri’nin Turkiye’de kalan bolumunde Oligochaeta faunasi bakimindan bu acikligi kapatmak ve daha sonraki calismalara temel olusturabilecek bir on calisma yapilmasi hedeflenmistir. Calisma sonunda 19’u Naididae (13 takson Naidinae, 6 takson Tubificinae) ve 6’ si Enchytraeidae familyalarina ait olmak uzere toplam 25 takson belirlenmistir. Calisma alaninda daha once Oligochaeta faunasinin belirlenmesine yonelik herhangi bir calisma yapilmadigindan tespit edilen taksonlar nehir icin yeni kayit niteligindedir

Denizli’deki dağ göllerinin Oligochaeta (Annelida) faunası üzerine gözlemler

Oz: Sandiras ve Cicekbaba Daglari zirvelerinde yer alan Kartal Golu ve zirveye yakin Gokceova Goleti, Honaz ilcesi yakinlarindaki Sakligol ve Bozkurt ilcesi yakinlarindaki Karagol’un Oligochaeta (Annelida) faunasini belirlemek uzere 2009, 2010 ve 2011 yillari Haziran, Temmuz ve Agustos aylarinda 4 ornekleme calismasi yapilmistir. Kalitatif degerlendirmeler sonucunda, ornekleme yapilan gollerin tumunden degisen sayilarda oligoket turleri tespit edilmis, 3 ordo iceriginde 3 familyaya ait bireyler tanimlanmistir. 17’si Naididae (14’u Tubificinae altfamilyasi, 3’u Naidinae altfamilyasi), 1’i Lumbriculidae ve 3’u Enchytraeidae olmak uzere toplam 21 Oligochaeta taksonu saptanmistir.

Nais christinae Kasprzak, 1973: an Oligochaeta species new for Turkey (Annelida: Naididae)

The family Naididae is one of the most important groups of aquatic Oligochaeta. It comprises 238 species (MARTIN et al. 2008), of which approximately 26 belong to the genus Nais Müller, 1774 (http://zipcodezoo.com/Key/Animalia/Nais_Genus.asp). Most species are cosmopolitan (WETZEL et al. 2000). 48 species of Naididae have been reported from Turkey so far, with 8 species belonging to Nais (N. communis Piguet, 1906, N. variabilis Piguet, 1906, N. simplex Piguet, 1906, N. bretscheri Michaelson, 1899, N. pardalis Piguet, 1906, N. elinguis Müller, 1774, N. barbata Müller, 1774, and N. pseudoptusa Piguet, 1906) (ARSLAN 2006). We have found Nais christinae Kasprzak, 1973, which is new to the Turkish Oligochaeta fauna. We collected mud and water samples monthly from ten different stations at Gümüldür stream in southwestern Turkey, between April 1993 and March 1994, in order to determine the Oligochaeta fauna. Samples were fixed on-site with 4% formaldehyde. Fixed material was again sieved with a 500 m sieve in the laboratory. After sorting the material, oligochaete specimens were preserved in 70% alcohol and prepared for identification on permanent mounts using CMCP 10 solution. The key by TIMM & VELDHUIJZEN VAN ZANTEN (2002) was used for species identification. The photographs of the species were taken by a digital camera (Olympus, Camedia, C-7070) attached to stereo and compound microscopes. The specimens are deposited in the Museum of the Faculty of Fisheries, Ege University, Turkey (ESFM), as whole permanent mounts. Roman numerals = segmental numbers. Our measurements are indicated in parentheses.
