(Opiliones: Phalangiidae), is described and illustrated based on males collected in north-eastern Anatolia, Turkey. The new species is similar to R. buresi (Šilhavý, 1965) and R. lenkoranica Snegovaya, 2007. The differences between these species are elaborated. http://www.zoobank.org/urn:lsid:zoobank.org:pub:A53452BB-A85D-4BE8-8A6B- D0FC3421AFE3 Keywords: Opiliones; Phalangiidae; Rilaena; new species; Turkey Introduction To date, 6534 species of Opiliones have been described in 1649 genera worldwide (Kury, 2013), but only 95 species belonging to 35 genera are known from Turkey (Kurt, 2014). The family Phalangiidae Latreille, 1802 consists of 55 genera with approximate- ly 394 species (Kury, 2013) including 49 species from Turkey (Kurt, 2014). Rilaena Šilhavý, 1965 is a genus of the Phalangiidae and includes approximately 15 species in the world (Snegovaya & Pkhakadze, 2014). So far, three of them have been recorded from Turkey: R. anatolica (Roewer, 1956), R. buresi (Šilhavý, 1965), R. gruberi Staręga, 1973 (Kurt, 2014). A new species of the genus Rilaena from Artvin province, Turkey, is described herein. Material and Methods Samples were collected by hand from grasses in the Artvin Province, Turkey. Examined speci- mens were preserved in 70% ethanol and deposited in the collection of the Arachnological Labor- atory of Şiran Vocational School, Gümüşhane University (GUSAL), Turkey.

Biodiversity Data Journal 8: e55242. https://doi.org/10.3897/BDJ.8.e55242 Abstract Background Since the late 1980s, long-term monitoring of various components of natural ecosystems under conditions of industrial pollution has been carried out in the Central Urals. In the mid-2000s, similar programmes were started in the Southern Urals. As a part of these monitoring programmes, the data on invertebrates in different types of biotopes, collected with different methods and in a different time intervals, continue to be gathered. Amongst the most well-studied groups of invertebrates are spiders and harvestmen whose communities are a convenient indicator of the environment. The data collected through these monitoring programmes can also be used to study natural local biodiversity. New information The dataset, presented here, includes information from a long-term monitoring programme for Araneae and Opiliones that inhabit grass stands of secondary dry meadows and litter of spruce-fir, aspen-birch and pine-birch forests in the Central and Southern Urals. The dataset (available from the GBIF network at https://www.gbif.org/dataset/e170dbd1- a67f-4514-841c-5296b290ca90) describes the assemblage structure of spiders and © Nesterkov A et al.

Many specific PCR primers have been developed for amplification of the rDNA cluster fragments from particular taxa. However, the use of universal primers hybridising to the conserved rDNA regions enables discovering sequences of eukaryote endosymbiont or pathogen origin in the analysed DNA sample. This approach makes it possible to detect gregarines (Protozoa: Apicomplexa) that are obligate parasites of digestive tracts and body cavities in invertebrate animals. Here we report new uncultured gregarine clones detected by rDNA sequencing in one harvestmen, Rilaena triangularis (Opiliones: Phalangioidea), and two astigmatid feather mite species, Proctophyllodes stylifer and P. ateri (Acari: Analgoidea). To our knowledge, this is the first record of parasitic Astigmata (cohort Psoroptidia) infected with gregarines. Comparison of the amplified rDNA fragments with sequences deposited in GenBank revealed that analysed sequences corresponded to 18S rDNA from the genera Gregarina (85 and 90 % identity with G. chortiocetes for sequences found in P. ateri and harvestman, and Syncystis (87 % identity with S.

  • Chemical Communication and Ecology in Eupnoi Harvestmen 2
    1 Chemical communication and ecology in Eupnoi harvestmen 2 3 Ignacio Escalante 4 Department of Environmental Science, Policy, & Management. University of California - Berkeley, 5 California, USA. Email: [email protected]. 130 Mulford Hall. Berkeley, CA, USA. 94720. 6 Abstract 7 Communication via chemical signals and cues is a widespread modality in animals. Producing, 8 transmitting, receiving and processing chemical compounds impose important challenges. Nonetheless, 9 certain arthropods rely almost exclusively on this channel for intra- and inter-specific communication. 10 Through a preliminary literature review, I summarize here the morphological, behavioral and evolutionary 11 implications of chemical communication in harvestmen (the arachnid order Opiliones), with particular 12 emphasis in one group: the Eupnoi or “Daddy Long-legs”. This group has a unique secretory gland that 13 opens in an ozopore in their dorsum. While relying mostly on short-range olfaction and contact 14 chemoreception using different setae, some harvestmen are known to use chemicals in defense, alarm, 15 spatial marking, recruitment, or reproduction. I then propose future research direction on the 16 mechanisms of production and the evolutionary history of these traits. Specific questions can include (1) 17 are chemical signals used as alarm pheromones in Eupnoi aggregations? (2) Do harvestmen rely on 18 chemicals to mark their traditional roosting sites? If so, what are the chemicals involved and how do 19 those differ from the ones used as alarm signals? Also, (3) what are the specific functions of the chemical 20 communication during in female-male communication and multi-specific roosting aggregations? And (4) 21 to what extent the use of chemical defenses imposes a trade-off with other defense mechanisms such as 22 ‘playing dead’ or voluntarily releasing legs.
