The genus PleurigonaMalloch, 1929 is newly recorded in China with the description of one new species, Pleurigona bicolor sp. nov. Photographs and illustrations are provided for the species.

Diplopoda are poorly studied in many regions. The last comprehensive work on the millipede fauna of Switzerland was published in 1993 and listed 124 outdoor-living species. Recent sampling efforts have resulted in the discovery of six millipede species of European origin that were not previously known to occur in Switzerland: Cylindroiulus britannicus (Verhoeff, 1891), C. salicivorusVerhoeff, 1908, C. vulnerarius (Berlese, 1888), Heteroiulus intermedius (Brölemann, 1892), Anamastigona pulchella (Silvestri, 1894) and Macrosternodesmus palicolaBrölemann, 1908. None of them is currently invasive in Switzerland, but some are rapidly expanding across Europe and other regions of the world. A species which was previously only known from northern Italy, H. intermedius, was found in a forest close to Bellinzona. It is likely a native Swiss species which has previously been overlooked. The other five species were collected in human-made habitats in the city of Basel and its surroundings, suggesting human-caused introduction. Two species, C. britannicus and M. palicola, likely have an Atlantic origin, while the three remaining species, C. salicivorus, C. vulnerarius and A. pulchella, are originally from Italy. The biogeography of these six species is discussed, and photographs of specimens of each species and their gonopods are presented.

The objectives of this study were to describe the composition and infection patterns of the helminth communities associated with four amphibians (P. minuta, B. pulchella, L. latrans and R. fernandezae) with different life-habits, and additionally to compare the helmith fauna associated with these amphibians in agroecosystems with different land use (crops and livestock). A total of 300 anuran individuals and twelve helminth taxa were collected in sites located northeast of the Province of Buenos Aires, Argentina. Helminth communities differed between amphibian species according to their habitat preference, digeneans were predominant in aquatic and arboreal amphibians (Hylidae) and nematodes with direct life cycle were found parasitizing semi-aquatic and terrestrial amphibians (Leptodactylidae and Bufonidae). In three of the frog species (B. pulchella, L. latrans and R. fernandezae), parasite prevalence did not vary significantly according to land use. The values of abundance and infracommunity species richness, meanwhile, varied according to land use, with the highest abundance values in crop sites and higher richness in livestock sites. Regardless of the use of land, L. latrans presented the highest values of prevalence, abundance, and richness of helminth species. This is the first study assessing the ecological aspects of parasite taxa in populations of P. minuta, B. pulchella and L. latrans that inhabit agroecosystems in Argentina.

A new genus, Karakumosa gen. nov., is established to accommodate nine central Asian species of burrowing wolf spiders, of which seven are diagnosed and described as new: K. badkhyzica sp. nov. (♂♀, southern Turkmenistan), K. gromovi sp. nov. (♂♀, southern Uzbekistan), K. repetek sp. nov. (♂♀, eastern Turkmenistan), K. shmatkoi sp. nov. (♂♀, northern Ciscaspian region and Azerbaijan), K. tashkumyr sp. nov. (♂, Kyrgyzstan), K. turanica sp. nov. (♂♀, Turkmenistan), K. zyuzini sp. nov. (♂♀, Uzbekistan). Two generic transfers are proposed: Karakumosa alticeps (Kroneberg, 1875), comb. nov. and K. medica (Pocock, 1889), comb. nov. (both ex HognaSimon, 1885). Lectotypes are designated for Tarentula alticepsKroneberg, 1875 (♂) and T. medicaPocock, 1889 (♂). The localities of all Karakumosa species are mapped, and an identification key is provided as well. A short overview of the fauna and diversity of the fossorial Lycosidae of Central Asia is given.

Here we revise the entire Ephemeroptera collection of F.-J. Pictet deposited in the Natural History Museum of Geneva (MHNG) and voucher specimens housed in the Natural History Museum of Vienna (NMW). Due to several unforeseen turns of events, the MHNG collection was already in bad condition at the end of the 19th century. However, the specimens sent by V. Kollar to F.-J. Pictet, and used by the latter for his monograph (1843-1845), have been well curated after their return to the NMW and allow an important nomenclatural change. The species Baetis forcipulaF.-J. Pictet, 1843 is now considered a junior subjective synonym of Ephemera venosaFabricius, 1775, currently Ecdyonurus (Ecdyonurus) venosus (Fabricius, 1775). The specimens described by Thomas in 1968b from southwestern France under the name Ecdyonurus forcipula (F.-J. Pictet, 1843) belong to a new species, Ecdyonurus alaini Bauernfeind sp. nov., which is described herein. Mayfly specimens described by F.-J. Pictet's son, A.-E. Pictet, are also reviewed. Furthermore, information is provided on some other valuable specimens housed in the MHNG and NMW, such as Ametropus fragilisAlbarda, 1878 which was already collected in Italy in the 19th century, or Rhithrogena cinctaNavás, 1921 from the Spanish Pyrenees, which is the second specimen currently known of this species.

Henri de Saussure described 32 species of cockroaches currently placed in the family Corydiidae, some of them in collaboration with Leo Zehntner. These species are listed alphabetically with an account of the type specimens in the Muséum d'histoire naturelle de Genève. The location of type specimens in other museums is given where known. The current binominal combination for each species is provided.

A collection of spiders from Kenya, assembled by Prof. Volker Mahnert and deposited in the Natural History Museum of Geneva, contains 16 identifiable linyphiid species. Among of them a new genus and two new species were revealed: Afrotrichona gen. nov., with Afrotrichona mahnerti sp. nov. as the type species, and Agyneta spinifera sp. nov. Males of Pelecopsis subflavaRussell-Smith & Jocqué, 1986, Lepthyphantes (s. str.) buensisBosmans & Jocqué, 1983, and Machadocara gongylioidesMiller, 1970 are illustrated and briefly redescribed. The latter two species, together with Agyneta habra (Locket, 1968), Metalepthyphantes vicinusLocket, 1968, Microctenonyx subitaneus (O. Pickard-Cambridge, 1875) and P. pasteuri (Berland in Fage & Simon, 1936), are reported for the Kenyan fauna for the first time. In addition, A. spinifera sp. nov. is also reported from Tanzania.

Diartiger wangzheni Yin & He, sp. nov. is diagnosed, described, and illustrated based on a male specimen collected in Sichuan, southwestern China. The new species was found in association with Lasius ants (Hymenoptera: Formicidae) under a flat rock. An updated key to the males of Diartiger species known from China is provided.

A new epiphytic, small-sized species of PlumulariaLamarck, 1816, P. roxanae sp. nov., is described based on fertile material from Bali, Indonesia. Its deep hydrothecae are characteristically narrowed distally through a distinctive hypertrophy of the free portion of their adaxial wall. Its minute gonothecae, however, are comparable in shape and size to those of the well-known, circumtropical P. floridanaNutting, 1900.

A second species of the genus CerochusaYin & Nomura, 2012, C. gesinae Yin & Kleeberg, sp. nov., is described and illustrated from Chiang Mai, Thailand. The new species can be easily distinguished from C. ciliocepsYin & Nomura, 2012 from China and Thailand by the less strongly modified male head, distinct discal striae of the elytra, dense pubescence along the posterior margin of the elytra, and different shape of the aedeagus.

A new family of laniatorean harvestmen from northern Thailand is proposed, Suthepiidae fam. nov., which comprises one new genus and one new species, Suthepia inermis sp. nov. This family stands out by characters hitherto unknown or rarely recorded for Opiliones, and close relatives of this taxon are presently not discernible. Important characters are a short and compact penis with a massively enlarged distal part with a rich armament of sclerites and membranes which can be moved and everted by hemolymph pressure during mating; the pedipalp of males and females is without raptorial adaptations, i.e. elevated sockets (= apophyses) carrying strong distal spines are completely absent, therefore no prey capture basket is present; the male pedipalpal tarsus is enlarged and compressed, its dorso-distal double apophysis presumably contains a gland; the pedipalpal claw is weak, not longer or stronger than long hyaline setae on the dorso-distal apophysis of the tarsus. The only specimens presently known were found in litter of a few forested mountain stocks, between 450 m and 1400 m altitude. A brief overview of Southeast Asian laniatorean families is presented.

Temporal comparisons of a site's biodiversity depend on the availability of at least two asynchronous data sets on a bioindicator group. The Sierra de Guadarrama, a mountain range in central Spain has a high biodiversity and representative sites such as El Ventorrillo Biological Station (Madrid province) play an important role in research and monitoring of the Sierra biodiversity. Although unevenly and randomly, hoverflies of the Sierra de Guadarrama have been surveyed for decades, but never at El Ventorrillo. This important group of pollinators, aphid predators and bioindicators was sampled with a Malaise trap at El Ventorrillo from June 1989 to June 1990. A total of 51 species were identified (20 spp. of Eristalinae and 31 spp. of Syrphinae), 22 of which were new to the Sierra de Guadarrama and 17 to the Madrid province. The genera Brachypalpus and Didea were also new to the Madrid province. The Sierra de Guadarrama now has 126 species recorded and the Madrid province 150. Within the Sierra de Guadarrama, El Ventorrillo becomes the second locality in number of hoverfly species recorded after El Escorial (64 spp.). In the Malaise trap catch, hoverflies with zoophagous larvae had a higher representation than those of other guilds, both in species richness and abundance. The results provided here for El Ventorrillo represent a baseline for future biodiversity studies at this site with a similar experimental design, for example, to detect changes in hoverfly diversities along time.

The Painted Wolf Snake, Lycodon pictus, was recently described based on the type series from Trung Khanh and Ha Lang districts in Cao Bang Province, northern Vietnam. Herein, we report new findings and a range extension of the recently described species. One individual was collected close by the type locality, in Ha Lang District, Cao Bang Province, Vietnam and another one in Nonggang National Nature Reserve, Longzhou County, Guangxi Zhuang Autonomous Region, China, approximately 60 km apart from the type locality. Both specimens generally accorded with the morphological diagnosis of L. pictus provided in the original description. Molecular analyses supported the morphological findings: the newly collected specimens were approximately 0.3-0.9% (cyt b) genetically divergent from those of the type series. Molecular analyses also revealed that the holotype of L. pictus, for which no sequences were available so far, showed, based on the results of a formalin protocol, about 0.9-1.3% differentiation from the remaining type series, 0.5% from the new record from Cao Bang and 0.9% from the new record from China. Based on the morphological and molecular findings, we herein present the first country record of L. pictus from China, with a detailed morphological description of the specimen from Nonggang National Nature Reserve and slightly extend the original diagnosis of the species.

Leptothele chang Schwendinger, sp. nov. (males and females) is described and additional localities of L. benchaRaven & Schwendinger, 1995 in southern Thailand are given. Malayathele Schwendinger, gen. nov. is established, and four new species from Peninsular Malaysia are placed in this genus. These are M. cameronensis Schwendinger, sp. nov. (male and female), M. kanching Schwendinger, sp. nov. (males and females), M. maculosa Schwendinger, sp. nov. (males and females) and M. ulu Schwendinger, sp. nov. (males and females). Identification keys to the genera of Euagridae in Asia and to the species of Leptothele and Malayathele gen. nov. are given. Information on variation of taxonomic characters, biology, sexual behaviour and biogeography is provided.
