| Karst caves are distinctly characterised by darkness, low to moderate temperatures, high humidity, and scarcity of organic matter. During the years of 2014–2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 116 genera, while 23.5 % were not identified to species level. Among these species, 85.8 % (211 species) belonged to Ascomycota; 7.3 % (18 species) belonged to Basidiomycota; 6.9 % (17 species) belonged to Mucoromycotina. The majority of these species have been previously known from other environments, mostly from plants or animals as pathogens, endophytes or via a... |

| In the anthers of flowering plants, gymnosperms, and seed ferns, tiny (¡1 mm) granules might occur on the radial and innermost tangential wall of secretory tapetum cells. These sporopollenin granules develop simultaneously with the pollen exine and are called orbicules or Ubisch bodies. The present paper focuses on two quite different topics associated with orbicules. The morphological and ultrastructural diversity of orbicules in the order Gentianales is summarized, and it is demonstrated that orbicules are a plesiomorphic feature in the order. Furthermore, orbicule characters seemed to be correlated with evolutionary trends in pollen dispersal unit and tapetum type features. In the second part, we report on our investigation of Corylus avellana L.... |

| The Artematopodidae is a species-poor beetle family with contentious relationships to byrrhoid and elateroid families. Recent molecular phylogenetic analyses brought ambiguous results based on a single sequenced species. We investigated the taxonomic placement of Artematopodidae within Elateriformia using ribosomal (18S, 28S) and mitochondrial (rrnL, cox1) molecular markers and three artematopodid species. Our analyses placed Artematopodidae close to Omethidae+Telegeusidae in a basal position of broadly defined Elateroidea. Additionally, we described the first artematopodid species from China – Eurypogon jaechi sp. nov. and E. heishuiensis sp. nov. These species are reported from mountains of Yunnan and can be easily distinguished from their Palaearctic... |

| During the course of research on mammal mycophagy and movement in the Northern Tablelands of New South Wales, Australia, extensive collections of sequestrate fungi were made, including numerous cortinarioid taxa. Historically any novel taxa would have been described in the cortinarioid sequestrate genera Descomyces, Hymenogaster, Protoglossum, Quadrispora, Thaxterogaster or Timgrovea based on broad morphological similarities of the sporocarps and spore ornamentation. However, consistent with other recent analyses of nuclear DNA regions, taxa from sequestrate genera were found to have affinities with Cortinarius and Descolea or Hebeloma, and to be scattered across many sections within Cortinarius. None of the historical sequestrate cortinarioid genera are... |

| The moss flora of Mindoro Island was updated based on the 2004–2006 expeditions conducted by the author. The island’s moss flora now consists of 282 species in 128 genera and 39 families, which is higher than Palawan but far less than those of Luzon and Mindanao. Generally, the flora is most abundant in the eastern rainy part of the island, especially along mid-elevations on the east-facing slope of the central mountain range in the transition zone between montane and mossy forests. Moss diversity is also greater in riverine forests than in inland forests at low elevations. Only three moss taxa, Rhaccocarpus alpinus, Dicranoloma daymannianum and Distichophyllum noguchianum, have their Philippine range restricted to the island. Distichophyllum noguchianum... |

| This is a study of the population fluctuation of euglossine species, as well as their preferences for scent baits (cineole, eugenol, vanillin and methyl salicylate) in two forest strata (canopy and understory) at the Reserva Florestal do Azulão, a forest fragment located in the municipality of Dourados, MS, Brazil (22°12'S, 54°55'W). We collected a total of 529 males from four genera and eight species. Diversity and equitability for both strata (understory: H' = 1.195 and J' = 0.6139; canopy: H' = 1.193 and J' = 0.6131) did not show a significant difference and a high similarity index was found (P = 87.5%). On the other hand, abundance was substantially higher in the canopy (n = 358) than in the understory (n = 171). From the scents used, eugenol attracted... |

| Adults of Tabanidae may become serious pests wherever they occur due to their attack to humans and others animals. Tabanids were captured near ground, water surface and at 25 m high on primary forests and forest gaps of anthropogenic origin, to understand their abundance, seasonality, diversity and similarity on such environments. Collections were carried out in the Base II of the War Instruction Center in the Jungle (CIGS) located at 54 km from Manaus municipality, Amazonas state. Two Malaise flight interception traps and four attraction traps (two suspended at 25 m high and two above the water surface of igarapé) were installed in forest gap and primary forest, areas for 10 consecutive days, during 15 months. A total of 2,643 specimens of 66 species were... |

| The order Thysanoptera comprises mostly phytophagous or fungivorous species, with a few species that are predators. Recent studies have emphasized the diversity of behavioural patterns amongst these diminutive insects. From the 5,500 species known worldwide, about 10% are recorded from Brazil, mostly tropical areas. In this work we surveyed the Thysanoptera fauna of a southern locality, 800 km south of the Tropic of Capricorn. The study site was ''Parque Estadual de Itapuã'' (30°22'S 51°02'W), Viamão, RS, and thrips were sampled from wild flowers, branches, grass and litter, from June 1999 to May 2001. A total of 83 species in 32 genera was found, but only 29 of these species could be identified, emphasizing the poor knowledge of the insect fauna of... |

| This work was carried out in order to determinate the local fimiculous Staphylinidae species due to these predators and or parasites importance on the natural control of the dung associated bovine parasites. For that, fecal masses 1, 2 and 3 days old were weekly collected on a pasture of Brachiaria decumbens Stapf, from May 1990 through April 1992. The feces were conditioned in 15-liter opaque plastic buckets, containing lateral and top openings, where flasks were fastened for capturing Staphylinidae beetles present in these masses, during a 40-day period. After this period the soil and fecal masses from the buckets were examined and the remaining insects collected. A total of 13215 specimens were collected, belonging to 34 species. The following twelve... |

| The coreoid fauna from Neotropics is poorly known, especially in terms of community studies. Aiming at contributing to this knowledge, a two-year study was carried out at Parque Estadual do Turvo, Municipality of Derrubadas, state of Rio Grande do Sul, Brazil, to evaluate the composition, abundance and species richness of Coreoidea. Samplings were conducted in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using beating tray method, along two trails of the park. Sampling effort (hours X collectors) totaled 153h. A total of 282 individuals of Coreoidea were collected, distributed in 28 species of Alydidae, Coreidae and Rhopalidae. The most abundant species was the coreid Cebrenis supina Brailovsky, representing 16% of the... |

| In this work, an alternative method for the capture of neotropical social wasps is described, which may supplement or replace the procedures commonly used in wasp surveys. The method was tested in a seasonal semideciduous forest in the northwest of São Paulo State, collecting a larger number of species and a greater abundance of social wasps and of other Hymenoptera than other methods also used in the same area, namely Malaise traps, bottle traps and meat baits. The proposed method was adapted from Wille (1962) who used an attractive solution based on water and honey for bee attraction. In here, the attractive solution was based on water, salt and crystal sugar, and was effective in attracting bees and solitary wasps, but mainly social wasps, which is the... |

| Coleoptera associated to undisturbed cattle droppings in pastures present great diversity and abundance. Several species are of primary veterinary importance for they may act as natural enemies of pest insects that breed in this habitat. To survey the diversity and abundance of Coleoptera associated to undisturbed cattle droppings, four undisturbed cattle dung pats naturally dropped in pastures and 5 cm of the soil immediately beneath them were collected almost all weekly from april 1992 to april 1994 in a farm located in the vicinity of São Carlos, State of São Paulo, Southeastern Brazil. Beetles were collected from the pats both using Berlese funnels and by allowing the beetles to emerge for 30 to 40 days. A total of 24,332 specimens belonging to 13... |

| We carried out a study to characterize fruit fly populations on an organic guava orchard (Psidium guajava cv. Paluma) in the municipality of Una, southern region of the state of Bahia, Brazil, using faunistic analysis of the adult fruit fly specimens captured in McPhail traps from January 2004 through March 2007. A total of 22,673 specimens of Anastrepha (15,306 females and 7,367 males) were captured. Thirteen species of Anastrepha were recorded. A. fraterculus and A. obliqua were the more frequent and dominant species, accounting for 90.1% of all females captured in the traps. A. fraterculus was the predominant species (more frequent, constant and dominant). The high value of the Simpson index (0.62) and the low values of Shannon-Wiener (0.83) and... |
