Full text

Abstract:

We redescribe and present new diagnoses of the Hylaeus gibbus group in Europe. Species of this group were often confused with each other. Our method of distinguishing between the species is based on dividing three commonly recognised species into four. We present diagnoses and list the characteristics of Hylaeus confusus Nylander, 1852; Hylaeus gibbus Saunders, 1850; and Hylaeus pictus (Smith, 1853). For the newly characterised form, one of Förster's available names has been resurrected—Hylaeus incongruus Förster, 1871. Hylaeus gibbus occurs only in southern Europe and northern to southern parts of central Europe, while H. incongruus reaches more northern latitudes. Types of the most problematic and poorly described forms were examined. Some names of clearly lost types were fixed by designating neotypes.

Abstract:

The paper presents data of around 4000 previously unpublished specimens, collected in various parts of the country during the last decades. With literature sources, a total of 86 species of the genus Hylaeus Fabricius, 1793 from 10 subgenera are compiled for Turkey. New for Turkey are 11 species: Hylaeus (Dentigera) kahri Förster, 1871, H. (Dentigera) pallidicornis Morawitz, 1876, H. (Hylaeus) deceptorius (Benoist, 1959), H. (Hylaeus) gracilicornis (Morawitz, 1867), H. (Hylaeus) paulus Bridwell, 1919, H. (Hylaeus) trisignatus Morawitz, 1876, H. (Nesoprosopis) pectoralis Förster, 1871, H. (Prosopis) incongruus Förster, 1871, H. (Prosopis) trinotatus (Pérez, 1896), H. (Prosopis) variolaris Morawitz, 1876 and H. (Spatulariella) sulphuripes (Gribodo, 1894). No new specimens could be found of 13 species which had been detected formerly. Our knowledge on the distribution of numerous species is greatly expanded. The characteristics of distribution are defined for the individual species. For example, H. meridionalis is the most widespread with records from 46 provinces covering all geographical regions of the country, while many other species are only known from one province, sometimes from a single record. The eastern part of Turkey, in particular the province of Hakkâri, proved to be an important centre of diversity for Hylaeus species. For a number of species the valid names had to be revised. Distribution maps are presented for the newly recorded and rare species. Frequently visited plant species are mentioned. Keys to the subgenera and species of Turkish Hylaeus are provided. Nomenclatural acts All species described by Warncke in 1981 and 1992 from Turkey in the genus Prosopis F. have not yet been revised and formally combined with the valid genus name Hylaeus F. There are however a number of online checklists, which have already registered most of these names under Hylaeus. Representatives of these checklists were checked here: The World Bee Checklist, integrated into the ITIS database (ITIS 2020) and Discover Life (Ascher & Pickering 2019). As new combinations, only the missing names are added here.Hylaeus (Dentigera) giresunus (Warncke, 1992) – comb. et stat. nov.Hylaeus (Hylaeus) trochilus (Warncke, 1992) – comb. et stat. nov.Hylaeus (Paraprosopis) decaocto (Warncke, 1992) – comb. nov.Hylaeus (Paraprosopis) socheri Dathe, 2010 = H.

Abstract:

We report the first record of the neotropical bee subgenus Hylaeus (Gongyloprosopis) Snelling, 1982 (Colletidae) for Brazil. Additionally, an overview of the current geographic records for the three known species of the subgenus is presented. We expand the distribution of Hylaeus (Gongyloprosopis) orbicus (Vachal, 1910), the male is illustrated, and the first floral association with Vismia japurensis Reichardt (Hypericaeae) is reported for this species.

Abstract:

Numerous orchid species are pollinated by food deception, where rewardless flowers attract foraging pollinators through the mimicry of other flowers or the use of non-specific floral signals. Here we investigate the pollination of Caladenia hildae, a member of a diverse Australian genus containing species pollinated by sexual deception, and species pollinated by food foraging pollinators. Despite eight bee species occurring at the main study site, only food foraging bees of a single species of Hylaeus (Colletidae) were observed to remove and deposit pollen of C. hildae. Spectral reflectance of C. hildae flowers differed from co-flowering rewarding species in terms of both the wavelengths of light reflected, and the pattern of colouration. As such, there was no evidence that C. hildae uses a pollination strategy based on floral mimicry. However, the attraction of only a single bee species at this site suggests that C. hildae may use a deceptive strategy that exploits sensory biases or behaviours that differ between Hylaeus sp. and the remainder of the bee community. While Hylaeus have been recorded visiting orchid flowers in several parts of the world, C. hildae may represent the first documented case of an orchid species specialised on pollination by Hylaeus bees.

Abstract:

AbstractWe document a novel exotic bee for North America, Hylaeus (Hylaeus) communis Nylander, 1852 (Hymenoptera: Colletidae), and determine whether it is likely to spread widely across the continent. To evaluate the extent to which H. communis behaves as a generalist and would be able to adapt to novel North American environments, we compare the breadth of its climatic, floral, habitat, and nesting preferences between its native European range and sites where it was first discovered in southern Québec, Canada. Specifically, we calculate the paired difference index, which approximates species generalism, from a set of bipartite networks linking Hylaeus Fabricius, 1793 species to their respective floral hosts and habitats. Results indicate that H. communis is the most adaptable bee of the European Hylaeus fauna and will likely acclimate to its new environment, being a greater generalist than an already widely established exotic bee, H. hyalinatus Smith, 1842. In southern Québec, we find that, despite visiting a wide variety of flowering species, it exhibits a strong association with non-native plants and resides almost exclusively in urban settings. We hypothesise that H. communis will be able to spread widely throughout North America via multiple human-mediated but accidental dispersal events and by following the distribution of European weeds and horticultural plants.

Abstract:

A subgeneric classification for the 318 currently recognised species of the genus Evylaeus recorded from the Palaearctic Region (in the narrower understanding) is suggested. It includes 29 subgenera all of which are keyed. An annotated list of subgenera contains diagnoses and information about type species, general geographic distribution, and species included. The following 19 new subgenera are described: Aerathalictus subg. n. (type species: Melitta aerata Kirby), Biennilaeus subg. n. (type species: Halictus marginatus Brullé), Crassevylaeus subg. n. (type species: Halictus crassepunctatus Blüthgen), Fratevylaeus subg. n. (type species: Halictus fratellus Pérez), Glauchalictus subg. n. (type species: Halictus problematicus Blüthgen), Laevinodilaeus subg. n. (type species: Halictus laevinodis Morawitz), Limbevylaeus subg. n. (type species: Halictus limbellus Morawitz), Loethalictus subg. n. (type species: Halictus loetus Brullé), Malachevylaeus subg. n. (type species: Melitta malachura Kirby), Minutulaeus subg. n. (type species: Hylaeus minutulus Schenck), Monilevylaeus subg. n. (type species: Halictus immunitus Vachal), Nitidiusculaeus subg. n. (type species: Melitta nitidiuscula Kirby), Nodicornevylaeus subg. n. (type species: Halictus nodicornis Morawitz), Pallidevylaeus subg. n. (type species: Nomioides pallida Radoszkowski), Pauxevylaeus subg. n. (type species: Hylaeus pauxillus Schenck), Tricinctevylaeus subg. n. (type species: Halictus tricinctus Schenck), Truncevylaeus subg. n. (type species: Halictus truncaticollis Morawitz), Virenshalictus subg. n. (type species: Hylaeus virens Erichson), Viridihalictus subg. n. (type species: Halictus viridis Brullé). Hylaeus politus Schenck is fixed as the type species of the subgenus Pyghalictus Warncke 1975. Evylaeus albitarsoides (Blüthgen) is resurrected as a valid species. The following new synonymies are ascertained: Halictus fedtschenkoi Blüthgen 1938 = Lasioglossum andromeda Ebmer 1978, syn. n.; Lasioglossum fratellus betulae Ebmer 1978 = L. nupricola Sakagami 1988, syn. n. The lectotype of Halictus fedtschenkoi Blüthgen is designated. Advantages of a more finely divided and hierarchically deeper classification of large taxa are discussed. A synonymic catalogue of species-group names of the Palaearctic Evylaeus, comprising 679 names, appended.

Abstract:

Study on the diversity of insect visitors on tomato flowers were conducted at Bina Sarana Bakti (BSB) organic farm, Cisarua, West Java. Diversity of insects were observed by observational method, an 10 m2 area of tomato plants in the morning, mid-day, and afternoon. Observations were conducted during 20 days. Diversity of visiting insects were analyzed by Shannon diversity and its evenness. Similarity of visiting insects between time of observations were analyzed by Jaccard similarity index. In organic farm, insect visitors of tomato plants consist of six orders belonging to eight species. Insect visitors of tomato flowers were dominated by Thrips sp. (Thysanoptera) and Hylaeus sp. (Hymenoptera). Hylaeus sp. was a main pollinator of tomato plants. Diversity of insect visitors in the morning and mid-day was higher than in the afternoon. Evenness of insect visitors of tomato flowers between observation times were relatively equal.

Abstract:

Hawaii has a single group of native bees belonging to the genus Hylaeus (Hymenoptera: Colletidae) and known collectively as Hawaiian yellow-faced bees. The majority of the 63 species have experienced significant declines in range and population. In 2016, seven species received federal protection under the Endangered Species Act of 1973. Competitors and predators, such as invasive bees, wasps and ants, are thought to be important drivers of range reductions and population declines, especially at lower elevations where more non-native species occur. We evaluated the effects of invasive ants on nesting Hylaeus anthracinus using artificial nest blocks that allowed us to track nest construction and development. The blocks were placed in pairs at 22 points encompassing three sites on the north and east sides of Oahu. One block in each pair was treated with a sticky barrier to prevent access by ants, while the other block remained untreated. From December 2015 to December 2016, we monitored 961 individual nests in the blocks. Seventy percent of nests in control blocks were invaded by ants. Nests in treated blocks were more likely to produce at least one adult than nests in untreated blocks (38% vs. 14%, respectively). In untreated blocks, ants were the most common cause of nest mortality followed by lack of development, displacement (primarily by the competitor Pachodynerus nasidens) and presumed pathogens. The invasive ant, Ochetellus glaber was the only observed nest predator, although the big-headed ant, Pheidole megacephala was also present. Hylaeus anthracinus inhabits coastal strand habitat which occurs in a narrow band just above the high tide line. Nests at one site were destroyed due to a high wave event, highlighting this species’ vulnerability to sea level rise. Additionally, no adult bees or nests were observed at the points where yellow crazy ants, Anoplolepis gracilipes were established. An increased understanding of the factors limiting Hawaii’s yellow-faced bees will provide information for future conservation efforts that may include landscape-scale ant control, habitat restoration and translocations.

Abstract:

Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pollen load, to study habitat disturbance, and bee conservation. However Neotropical trap-nesting bees’ taxonomy and biology are still poorly known and here we provide a review about these subjects. We searched for trap-nest bee studies in the Neotropical Region using Google Scholar and ISI Web of Science at any time in the past to December 2017. We found 109 independent studies, most of which were from Brazil (87 studies), followed by Argentina (10 studies), and other countries had fewer than five studies each. A total of 140 species, 24 genera, 10 tribes and three subfamilies were reported in trap-nests. Nest architecture was described for only 49 species. Taxonomy is only well-known for 14 genera, somewhat known for seven and is essentially unavailable for three genera. Construction material, closing plug and cell shape are similar among species in the same tribes and genera. Vestibular and intercalary cells, and the preliminary plug are variable, even at the specific level. Apinae is the most studied group with available data for all genera recorded in trap-nests. Colletinae is the least-studied group and nothing is known for their nesting biology. Megachilinae is intermediate, with some studies of taxonomy and nesting. We suggest that further trap-nest studies should provide more detailed information on nest architecture and construction materials, including explicit mention of structures that are absent. All Neotropical bees need more taxonomic studies, but some, such as Hylaeus and Megachile, require more attention since Hylaeus is essentially unknown and Megachile is very common on trap-nests.

In New Zealand unmanaged bees species can be important crop pollinators but their abundance and distribution is poorly known within hybrid carrot seed crops Standardised counts of bees visiting flowering carrot umbels (1350 umbels observed/field) across 19 commercial hybrid fields were conducted between 1000 h and 1500 h Despite honey bees being observed in all fields abundance varied greatly between fields (mean981; maximum330 minimum1) Other bees observed visiting umbels were Lasioglossum sordidum (17 fields; mean14; maximum65); Leioproctus sp (12 fields; mean20; maximum19); Hylaeus sp (one field; maximum 1) and Bombus terrestris (six fields; mean20; maximum11) The number of individual bees (all species together) counted/ umbel on male fertile umbels was significantly higher than on male sterile umbels a factor that could contribute to suboptimal pollen flow between umbel lines by bees Examination of their movements between male fertile and sterile lines is required to verify their efficiency as pollinators
