A survey on sensory organs of both sexes of the harvestman Dicranopalpus ramosus classifies structure and frequency of campaniform sensilla, falciform setae, sensilla basiconica, slit sensilla, solenidia, spines, sensilla chaetica, trichomes (simple hairs) and plumose setae. Sensilla are equally distributed on the pedipalp tarsi of both males and females, but females show higher counts of campaniform and falciform setae than males. Females furthermore have about 1000 glandular plumose setae on each pedipalp, that at the same positions in males are replaced by sensilla chaetica. The walking legs of both sexes show a similar distribution of sensory organs, with females showing more sensilla basiconica at the legs I and II and more solenidia on the first pair of legs. Males have a large number of bipterate setae (about 2200 per specimen) at the metatarsi and tarsi of the third and fourth pair of legs. In females these are replaced by simple hairs. Although females show a similar (or slightly higher) number of leg sensilla than males, their density is higher due to their shorter legs. In both sexes the second pair of legs has the largest number of falciform setae, sensilla basiconica, chaetica and solenidia, followed by the legs I, III and IV. The first pair of legs has the highest density of falciform setae, sensilla basiconica and solenidia, followed by the legs II, III and IV. The genital operculum, sternites and tergites show a multitude of slit sensilla. The slit sensilla of the genital operculum and sternites are associated with insertion plaques of muscles operating the penis/ovipositor and regulating opisthosomal volume and hemolymph-pressure.
The spider collection (Arachnida: Araneae) from Albania and Kosovo in the Senckenberg Research Institute, Frankfurt am Main is reviewed. A total of 122 adult specimens were found belonging to 73 species. Records of 48 species for Albania and 28 species for Kosovo, 20 of them new to Kosovo, are presented. Furthermore there are seven new country records for Albania: Platnickina nigropunctata, Erigone remota, Tenuiphantes tenebricola, Pardosa agrestis, Callobius claustrarius and Zelotes femellus. Additionally, Pardosa cavannae is the first record for the Balkan Peninsula. So far 381 species are known for Albania. A total of 106 species is known from Kosovo now; a list of the 86 spider species formerly known to Kosovo is included.
The whip spider collection (Arachnida, Amblypygi) held in the Natural History Museum Vienna, Austria
(2013)
We present data and remarks on the history and contents of the whip spider collection housed in the Natural History Museum of Vienna, Austria. The collection comprises a total of 167 specimens from 4 families, 10 genera and 27 species. It includes types of four species: Charinus ioanniticus (Kritscher, 1959), Damon brachialis Weygoldt, 1999, Phrynus parvulus (Pocock, 1902) and Paraphrynus mexicanus (Bilimek, 1867). Short notes on interesting objects and former curators are provided as well as an appendix with a list of species kept alive by Michael Seiter.
Vom 23. bis 28. Juni 2013 fand der 19. Internationale Arachnologiekongress statt, zum ersten Mal in Asien, im subtropischen Süden Taiwans. Im luxuriösen Howard Beach Resort Hotelkomplex am Kenting Beach im Kenting Nationalpark am südlichsten Zipfel Taiwans trafen sich 248 ArachnologInnen aus 40 Ländern. 133 Vorträge und 69 Posterpräsentationen wurden gezeigt.
Zwei Fälle von abweichender epigyner Form in Pardosa palustris (Linnaeus, 1758) werden beschrieben. Charakteristisch ist das Fehlen der hinteren Seitenteile des Septums. Mögliche Ursachen, wie zum Beispiel "Genitalschaden" bei der Paarung oder die Auswirkungen von Parasitenbefall, werden diskutiert.
[book review:] David Penney (Ed) 2013 Spider research in the 21st century – trends and perspectives
(2013)
The latest arachnological publication from Siri Scientific Press is a substantial compendium of spiderrelated topics covering many aspects of these fascinating animals’ biology. As the title suggests, the overarching theme running throughout this work are the advances which have been made in recent years – particularly through the application of novel methods and/or technologies – as well as productive directions for future research. Following an extensive foreword by Norman Platnick, which summarises the book’s main conclusions rather well, the volume itself is divided into nine self-contained and fully referenced chapters. All have been written by acknowledged experts in their fields and all provide an excellent account of the modern literature.
The pseudoscorpion genus Megachernes is recorded for the first time in Iran. Adults and protonymphs of Megachernes pavlovskyi Redikorzev, 1949 were found in a porcupine nest and under stones in the Deh Sheikh (Pataveh) cave, Kohgiluyeh and Boyer-Ahmad Province, Southwest Iran. A short description of the species is provided, based on the main morphological and morphometric characters of the adults.
Auch wenn der Titel lediglich eine „non-annotated checklist“ verheißt, handelt es sich tatsächlich um mehr. Es ist die Neuauflage bzw. die Fortschreibung des Kataloges von Mikhailov (1997) sowie von dessen Ergänzungen (Mikhailov 1998, 1998, 2000). Die Checklist (der Katalogteil) umfasst alle Arten, die in den heutigen Ländern der ehemaligen Sowjetunion bis einschließlich 2011 nachgewiesen wurden.
