Beitr. 49/2 1309-1321 11.12.2017 Fauna of Ascoidea (except Ameroseiidae) in Guilan province, Iran with two new species record for Iran mites fauna Fatemeh KARAMI, Jalil HAJIZADEH & Hadi OSTOVAN A b s t r a c t : A faunistic study of superfamily Ascoidea (Acari: Mesostigmata) except family Ameroseiidae in Guilan province, Northern Iran was carried out during 2015-2016. During this study 13 species of seven genera belong to two families Ascidae and Melicharidae were collected and identified. Four species namely Asca aphidioides (LINNAEUS), Zerconopsis michaeli EVANS & HYATT, Antennoseius (Antennoseius) bacatus ATHIAS-HENRIOT from family Ascidae and Proctolaelaps scolyti EVANS from family Melicharidae are new records for the mites fauna of Guilan Province. Proctolaelaps fiseri SAMŠIŇÁK (Melicharidae) and Zerconopsis remiger (KRAMER) (Ascidae) are new for Iran mites fauna. Expanded descriptions including illustrations of the adult female of Proctolaelaps fiseri and Zerconopsis remiger, respectively are provided based on the Iranian material. K e y w o r d s : Fauna, Ascoidea, Mesostigmata, New records, Iran. Introduction The superfamily Ascoidea is richly represented in tropical, temperate, and arctic alpine regions, where many of its members are free-living predators of nematodes and micro- arthropods in soil or humus and suspended arboreal litter habitats. -

More recently, this group has been treated at the generic level or as a subgenus of Hypoaspis Canestrini, 1885. One of the objectives of the present paper is to provide a detailed characterisation of Cosmolaelaps, here considered at the generic level, a group that was poorly char- acterised in its original description as well as in subsequent publications. It is most closely related to Stratiolaelaps Ber- lese, from which it can usually be distinguished by the presence of extra paired and unpaired setae on the opisthonotal region of the dorsal shield, as well as by not having hypertrophied chelicerae or corniculi. A total of 108 species belong to Cosmolaelaps, including the new species described here. Five other species may also belong to this genus, but the avail- able published information does not allow their conclusive placement. -

Soil Mite Communities (Acari: Mesostigmata) As Indicators of Urban Ecosystems in Bucharest, Romania M
www.nature.com/scientificreports OPEN Soil mite communities (Acari: Mesostigmata) as indicators of urban ecosystems in Bucharest, Romania M. Manu1,5*, R. I. Băncilă2,3,5, C. C. Bîrsan1, O. Mountford4 & M. Onete1 The aim of the present study was to establish the efect of management type and of environmental variables on the structure, abundance and species richness of soil mites (Acari: Mesostigmata) in twelve urban green areas in Bucharest-Romania. Three categories of ecosystem based upon management type were investigated: protected area, managed (metropolitan, municipal and district parks) and unmanaged urban areas. The environmental variables which were analysed were: soil and air temperature, soil moisture and atmospheric humidity, soil pH and soil penetration resistance. In June 2017, 480 soil samples were taken, using MacFadyen soil core. The same number of measures was made for quantifcation of environmental variables. Considering these, we observed that soil temperature, air temperature, air humidity and soil penetration resistance difered signifcantly between all three types of managed urban green area. All investigated environmental variables, especially soil pH, were signifcantly related to community assemblage. Analysing the entire Mesostigmata community, 68 species were identifed, with 790 individuals and 49 immatures. In order to highlight the response of the soil mite communities to the urban conditions, Shannon, dominance, equitability and soil maturity indices were quantifed. With one exception (numerical abundance), these indices recorded higher values in unmanaged green areas compared to managed ecosystems. The same trend was observed between diferent types of managed green areas, with metropolitan parks having a richer acarological fauna than the municipal or district parks. -

[email protected]; [email protected]; [email protected]; [email protected] RESUMEN. El objetivo principal de este estudio fue evaluar la diversidad de arañas del Área Natural Protegida Isla Quevedo. Se realizó un estudio comparativo de la riqueza y abundancia del orden Araneae en 3 tipos de vegetación: matorral espinoso, manglar y dunas. Los especímenes colectados se obtuvieron mediante 3 métodos: colecta manual, red de golpeo y trampas pitfall. Se obtuvieron 302 arañas en total, todas del suborden Araneomorphae, pertenecientes a 10 familias, 17 géneros y 22 especies. En el matorral espinoso se registraron 14 especies, 5 de las cuales se comparten con el manglar. Las 22 especies determinadas representan el primer inventario del orden Araneae para la isla. La mayor riqueza y abundancia se registró en el matorral espinoso, seguido por el manglar y después las dunas, lo cual comprueba que las arañas son abundantes en zonas de vegetación diversa. Palabras clave: Araneae, diversidad, Isla Quevedo, riqueza de especies, arañas. Diversity of spiders in Quevedo Island, Sinaloa, Mexico ABSTRACT. Main objective of this study was to evaluate the diversity of spiders at Protected Natural Area Quevedo Island.

Phoretic on Bark Beetles (Coleoptera: Scolytinae): Global Generalists, Local Specialists?
ARTHROPOD BIOLOGY Diversity and Host Use of Mites (Acari: Mesostigmata, Oribatida) Phoretic on Bark Beetles (Coleoptera: Scolytinae): Global Generalists, Local Specialists? 1,2,3 1 2 WAYNE KNEE, MARK R. FORBES, AND FRE´ DE´ RIC BEAULIEU Ann. Entomol. Soc. Am. 106(3): 339Ð350 (2013); DOI: http://dx.doi.org/10.1603/AN12092 ABSTRACT Mites (Arachnida: Acari) are one of the most diverse groups of organisms associated with bark beetles (Curculionidae: Scolytinae), but their taxonomy and ecology are poorly understood, including in Canada. Here we address this by describing the diversity, species composition, and host associations of mesostigmatic and oribatid mites collected from scolytines across four sites in eastern Ontario, Canada, in 2008 and 2009. Using Lindgren funnel traps baited with ␣-pinene, ethanol lures, or Ips pini (Say) pheromone lures, a total of 5,635 bark beetles (30 species) were collected, and 16.4% of these beetles had at least one mite. From these beetles, a total of 2,424 mites representing 33 species from seven families were collected. The majority of mite species had a narrow host range from one (33.3%) or two (36.4%) host species, and fewer species had a host range of three or more hosts (30.3%). This study represents the Þrst broad investigation of the acarofauna of scolytines in Canada, and we expand upon the known (worldwide) host records of described mite species by 19%, and uncover 12 new species. Half (7) of the 14 most common mites collected in this study showed a marked preference for a single host species, which contradicts the hypothesis that nonparasitic mites are typically not host speciÞc, at least locally.
